- A quick and simple explanation of why the moon's shadow moves across the earth from west to east during the solar eclipse. Many flat earth proponents think they have debunked the globe, but as always their claims are based on a misunderstanding of the science. Unfortunately, scientists are not doing a good job of explaining this, particularly with this video titled "Dear Science: Why does the eclipse shadow travel from west to east?" • Dear Science: Why does...
Look up the sizes, distances, and speeds of the earth and the moon, and do your own math, and you will see it works if you do it correctly. One minor correction: The moon's orbital period in relation to the sun, called a synodic month, is about 29 and a half days, not 27, but that does not change the explanation. If you do the math, be sure to use the synodic month, not the sidereal month.
Sorry for the background noises and the simple crayon drawing. I just wanted to do something simple and easy to understand, so we recorded it at the restaurant while we waited for our dinner. :)
All I know is this guy has the greatest patience of anyone, he makes me want to be a better person.
I really like this video - education for Flat Earth believers with crayons. So, appropriate.
Boxspot .. Excellent.
LOL :D :D :D
I tried educating a Flat Earther with crayons. He ate them.
tony kamps well said. They must all be inbred
owen, nice one. earth is flat motionless and beautiful.
And, if I'm not mistaken, the shadow moves across earth surface at about 1000 MPH! If you're on a mountain overlooking a valley that the shadow is coming across, you can actually see the moons shadow traveling really fast, I mean it's amazing how quickly it covers the distance from where you first see in until it hits you...
Most people do not realize that the Moon while rising and setting east to west is actually moving eastward in the sky with respect to the stars and planets. It moves east by the width of its own diameter EVERY HOUR. Just knowing this explains why the eclipse shadow moves west to east. Each 24 hour day, the Moon will be found approximately 12 degrees to the East in the sky than the day before.
The fact Eric Dubay somehow has more subscribers than you boggles my mind.
most people aren't so insecure that they need to subscribe to a channel telling them the earth is a globe.
one might as well sub to a channel that explains the religion of the pope and where bears go to shit.
Nathan Grant Check out explore bears and bison.
AlexanderKrah, many of Eric's subscribers are debunkers, not believers.
proof in the #s?
Jordan Pierce, proof of what? Because he has followers doesn't mean he is telling the truth. I don't believe anything he says and I follow him, just to see what he says next..
What this guy is saying is correct!
Since the moon travels east to block the sun to create the eclipse, the shadow of the moon will start in the west then travel east. BUT the earth rotates way faster than the moon's orbit so we will always see the shadow from east to west. No matter what!
The moon physically orbits faster but with it's distance, it takes 27 days to complete an orbit.
The moon would have to complete it's orbit in less than 24 hours in order for it's shadow to cast west to east. Which is impossible because the sun rises in the east and sets in the west because of how fast we are rotating east.
I didn't make this up it's science...the only issue is what we were taught does not add up to what we witnessed in the eclipse. Stay woke
CORRECT. So the official story and explanation remains a complete fallacy lol~
That moon moving 2000 miles an hour must be a fucker to land something on that! You know😉
If only the moon had this thing called Gravity...
^^ That...And if only we had something called rockets to match speed with the moon...
Xain And if only those rockets could get beyond low earth
The Mad Flatter
They absolutely can and have.
Xain prove it
You could have added that the moon seems to rise in the east, and set in the west, but it is rotating the same direction as the earth.
If the earth spins faster it will surpass moon rotation and the shadow will go east to west.
CHECK YOUR SCIENCE HISTORY DUMBSHIT. BEFORE YOU START SPOUTING OFF IMAGINARY ANSWERS.
I think this is the simplest explanation I've seen of this. Many people assume that the moon is moving East to West in its orbit because that's the direction we see it go from our vantage point.
An alternative explanation would be to look at it from an earth-bound perspective and looking purely relative speeds.
- The sun crosses the sky once every 24 hours: 15°/hour.
- The moon is a little slower at around 24.8 hours, so about 14.5°/hour.
The key-point is that the sun crosses the sky *faster* than the moon, even though the sun is on the outside track so to speak. The sun catches up to the moon.
You can model this with 3 circles (from outside to in: sun's path, moon's path, earth), but really don't even have to. The only thing that needs to be demonstrated is how a shadow can seem to move "backwards", and that can be done with linear velocities just as well.
Take a simple flashlight, some object and a wall. These represent the sun, moon and earth, respectively.
In the first demonstration, keep the object stationary and move the light (the 'sun') from right to left behind the 'moon'. This simulates the sun overtaking the moon. The shadow on the wall will move from left to right, _even though the 'sun' moves right-to-left!_ This, of course, is simply because of how projections work.
The second demonstration would involve a moving 'moon' too, but at a lower speed than the 'sun'. You'll get the same effect. Only if the 'moon' were to move faster than the 'sun' would you get a right-to-left shadow.
If this still isn't enough, you can do it with circles to model how it works with an actual sun, moon and earth. You'll get the same thing, of course.
You should make a video to share that with the rest us.
Funny thing is you just described how to perform this test on the flat earth model. The wall being the earth is stationary and the sun and the moon move around the plane. What you need to do is hold the flashlight (sun) still and you use a globe or ball to represent earth and a ball to represent the moon and move them according to the motions that we are told and see if you can move the shadow from west to east.
Oh sure, you can use the test for a flat earth model as well. It'll work for a banana-shaped earth too. The shape of the wall is mostly irrelevant to the direction of the shadow. As is which items are moving, as long as you get the relative movements correct. It's just that using a flat, stationary surface makes illustrations considerably easier.
The point of dispute here is that flat earthers claim that since both the sun and moon travel from east to west, the moon's shadow should travel east-to-west as well. But that's simply not how shadows work. That's what I was getting at: what matters is the *relative apparent speeds* between the light and object as seen from the observer location.
"What you need to do is hold the flashlight (sun) still and you use a globe or ball to represent earth and a ball to represent the moon and move them according to the motions that we are told and see if you can move the shadow from west to east."
No you don't need to do that at all. All you have to show is that the shadow can move in the opposite direction as the light and object causing it, as that's the root of their objection. Again: all that matters are the *relative apparent speeds.*
In case of the sun-moon-earth system, the relative speeds are such that, as seen from the earth, the sun will overtake the moon from the east. Shadows always come from the opposite direction, so the moon's shadow will come from the west. That's all it is.
Look at Flat Earth Math's and Sly Sparkane's channels for more details. They have videos on eclipses that show you exactly how it works.
Yes it does make a difference. According to ball idea the sun doesn’t move and the earth revolves around the sun as the moon revolves around the earth. So if you are moving the flashlight across the wall then you are moving the sun. Again I challenge you to perform a more accurate test using a stationary sun with a moving globe and moon. In the flat earth idea the earth dose not move and the sun and moon move around in a circle over the earth. On their model the eclipse does work.
But now onto the real problem with the ball idea. As we are told the earth does not sit still while the moon orbits, it is also moving in an orbit around the sun. So as the moon travels around the earth on the side away from the sun (our night sky) for 14 days (to complete half of its orbit) it is going to have to travel a much greater distance than it does when it travels between the earth and the sun (our daytime sky) for those 14 days. So to maintain its constant visual to us on earth it is going to have to change its speed greatly. As well as its rotation speed to make sure that we only see the same side of the moon. Kinda like if I (earth) was to run in a big circle around an object (sun) and you (moon) were to run circles (orbit) around me.
Whelp, yeah you're right, looks like I spoke too soon :S
While it's still true that you need to look at relative speeds, when the observer is offset from the center of rotation, getting those relative speeds turns out to be ... complicated.
I have a small Excel model where the sun is fixed, the moon orbits and the earth rotates, just as you wanted. As predicted, the shadow moves west-east. However, once the moon's orbital period increases to about 60 days (coincidentally, the ratio between lunar orbit and earth diameters), things start to get weird.
Below 60 days, it's always west-to-east. Above ~70, it's east-to-west. In between is some sort of transitional stage where you get to see three eclipses in some spots O_o. My guess is that this happens for a similar reason as retrograde motions of planets, but that's just a guess for now. And this is assuming I've modeled it correctly, of course. For now it's just a simple 2D model and I haven't even begun to take tilt, oblateness and eccentricity into account.
Oh, and note that you'll get similar complications in a flat earth model. But since there is no flat earth model that can predict the positions of the sun and moon accurately anyway, attempting to predict eclipses with it is a somewhat pointless.
Flat earthers are simply those who skipped physics class
No they dropped out around grade 4.
Wow who would of thought someone on CZcams would make sense
The moon is moving faster, yes, if we're talking mph. But it cannot keep up with the earth's spin. If it could, it would set in the east; not in the west. The reason it set in the west is because the earth "leaves it in the dust".
bammbamm12 "The moon is moving faster, yes, if we're talking mph. But it cannot keep up with the earth's spin."
What? The Moon, or the Moon's shadow?
"If it could, it would set in the east; not in the west. The reason it set in the west is because the earth "leaves it in the dust".
You're confusing the movement of the shadow with the Moon as you see it from the surface.
Moon's shadow - but what's the difference?
So you're claiming that this animation is false? It shows the shadow moving faster than the earth's spin, in the heliocentric setup.
"Moon's shadow - but what's the difference? "
So you're saying the Moon's shadow, at the time of the eclipse, could not keep up with the Earth's surface?
"So you're claiming that this animation is false?"
No, I don't think I said that.
You're being cagey. As you were.
A concept that has the flat earth people mystified and convinced of the NASA conspiracy, and you explained it in 5 minutes, literally in crayon... so appropriate. #salute
Think about it this way. The moon moves across the sky east to west, but the sun moves east to west faster. Now do you see how the shadow moves west to east?
Here are a few of my best eclipse pics from Oregon. Yes it arrived exactly as predicted by the heliocentric model. ;)
imgur.com/a/42T6J
How many stars did you see during totality?
VOYSOVREASON--eclipses were predicted for several millennia before the heliocentric model was believed.
Ed Younica - Predicting by recognizing the recurring pattern is NOT the same as calculating it based on the actual mechanisms. They could not calculate the precise time and path like we can today.
VOYOVREASON--It sounds like you want to believe that this MODEL is the source of prediction. The Model does not increase our knowledge so we don't have to worship it. On humans predicting eclipses thousands of years ago
"It turns out - here's your word for the day: Saros - that the geometry of the sun and Earth and moon repeats with a period of 18 years, 11 days and eight hours, almost exactly. So on Aug. 10 in 1999, there was a total eclipse of the sun. It had almost exactly the same path, almost exactly the same duration, in the same latitudes on the Earth. But because of that eight-hour difference, it didn't take place over the U.S., it took place over Europe. And so that Saros, that notion of that periodicity, that long-range periodicity, has been known since ancient times. And if you think about it, three Saros cycles, the eight hours add up and so every 54 years, a total eclipse of the sun happens about in the same place as it did 50 years before. The Babylonians and Assyrians knew this as early as 200 or 300 B.C. And so they've been able to tell us that eclipses were coming for that long. It's remarkable that they had the wherewithal to figure that out."
Ed Younica - you’re right, it is amazing just how smart ancient people were and how easy it is for us today to under estimate them. Look at the ancient Chinese, who invented printing, the compass, gunpowder and made the first recorded observations of solar eclipses and comets. The ancient Greeks like Democritus, developing the atomic theory in the fifth century BC. Or, Aristotle describing a spherical world 2,000 years ago in his book ‘On The Heavens’. Unfortunately, but just as amazing and at the complete polar opposite, we have people today still believing in an ancient bible book of myth and nonsense over modern science, formal education and learning.
Thank you for this simple explanation. Maybe if the most basic astronomy class were a requirement in high school, we wouldn't have these flat earthers all over the place. The funny thing about this eclipse coming up in about a week is that no flat earth model can support an eclipse, since the flat earth theory is predicated on the sun and moon always being above the earth. This of course means that we could never view the sun and moon overlapping on earth. This is quite an inconvenient and indisputable fact for the flat earth community.
the shadow may move from west to east on the ball, but the spin would still cause the shadow to move from east to west. in order for it to work you have to use reference frame, which calls for a stationary earth. its impossible on the heliocentric model to replicate this event using precise spins and orbits, if you actually try to replicate this the only way for it to work like i said, is to keep the earth still. which is never the case in the heliocentric lie. the fe is stationary, and if the sun is moving at 15 degrees an hour while the moon is moving 13.3 degrees an hour the westward shadow works. it doesnt on the ball model. try to replicate it.
1 lives Gaming - The earth moves yes, around the sun, but only about 1 degree per day (360 degrees / 365 days), and the eclipse only lasts about 90 minutes, so it only moves about 6% of one degree during that time (1.5 hours / 24 hours). So the earth movement around the sun is negligible, AND the moon moves with the earth around the sun. So my analysis is valid.
A solar eclipse on a flat earth would not follow the path this one follows, sweeping down from NW to SE, it would have to be parallel to the equator. Explain that.
Here is a good description of all the factors involved.
www.space.com/36388-total-solar-eclipse-2017-duration.html
Sun is an omnidirectional light source... would it even have an effect if we would spin 360 degree in 1 minute?
Go look at my comment. Your own comment explains why the shadow moves west to east, then you turn around and don't believe what you just proved
Hey I did my simulation and I now understand why the shadow moves west to east. As I said try to prove myself wrong. And I can see how people think of the process as very counterintuitive.
I think what people like you should do when you do these demonstrations is draw a rigid shadow column extending out from the moon and directly extended away from the sun thus always pointed in the same direction even though the moon moves in an arch. It'll easily get the point and concept across.
Since the shadow column is rigid and it's moving at a 1-to-1 ratio extending straight out from the moon, which is moving at approximately 2288mph in relation to the earth, the shadow column is also moving at 2288mph.
The moons speed is instantaneously getting translated down to Earth. This is a critical point the flat earthers are missing. They're envisioning the shadow moving in an arch like a bike wheel fixed at the center of the Earth and not totally perpendicular across the earth.
Thus when the shadow column crosses the Earth, moving at 2288mph, it's overtaking the Earth's own 1000mph velocity and the difference between the two speeds gives us the actual speed of the shadow from west to east. Which is key here. It's an illusion caused by the light of the sun, the moons speed and the moons shadow speed against the Earth's speed.
Take away the light of the sun and hence the shadow column and the illusion of the moon going west to east goes away.
Thank you so much for the experience. It really helped me learn alot.
I'm not convinced. I'm thinking this was really good photorealistic CGI? You should work for Pixar, those meaty hands looked totally realistic. But yeah, the shadow will move West to East. :-)
Flat Earth Math - ha ha good one.
VoysovReason what i am most afraid of is that this guy is serious.
Barend Bank, he' not. :)
I'm pretty sure.
+Barend Bank I was serious when I described those hands as "meaty." :-)
The Van Allen belts would totally melt any crayon! FAYK!!!!1!!
Perfect intuitive common sense.
I didn't think it existed on you tube.
Thank you
that doesnt make any sense. The moon would have to travel around the earth less than 24 hours.

Ricky Summer - Apparently you missed the part about the moon's path being SIXTY TIMES LONGER than the earth's surface path. Think!
A fantastic explanation - and something I have not thought about before. Your videos are always a joy to watch.
It's sad that we need to explain these things to the stupid masses 🤦🏻♂️(face palm)
Mercury 7 Not at all. It's not remotely intuitive that the moon is travelling at twice the speed of the surface of the Earth, and no-one should be called stupid for needing it to be explained. If you explain it and they still say "Yes, but flat Earth," then feel free to call them stupid.
I don't think this qualifies and common knowledge. If you know it, you know it, but most people don't know this.
Michael Zentz that's the simple answer I was looking for lol
Michael Zentz lol only if you're under the impression that the circumference of the moon's orbit is comparable to the circumference of the Earth. If so, you're only off by a factor of 60 or so.
Michael Zentz No, it's saying that the moon is travelling faster through space that the surface of the Earth is moving through space. Therefore the shadow of the moon on the surface travels faster than the surface that it's travelling across. I'm not being facetious when I ask, what part of that don't you understand?
Solar Eclipse Shadows always move West to East. Not just this one.
Excellent explanation. Flat earths will say its buoyancy or some shite like that. Keep them coming sir!
Maybe it's gravity because the crayon is pulled toward the center of the Earth because the rotation and spin of the heliosphere circle Paul your train of the sun that the black hole is going to the left equals MC square pie turtles move up and down because frogs jump over hills and cell phones work because pickles are green
flat earthers are just little kids who never grew up lol. they literally ask questions that a 4 year old would ask. which i can understand from a 4 year old. not from a grown up.
Thank you for crushing the Flattards only hope
Mark Seven You mean,The globes only hope if it moves in the opposite direction and increases in size exponentially
Crushing! Destroying! hahah
Mark Seven we did it yes
Emperor's New Clothes. Sure. You did it. You did it by changing the established model to suit your needs.
The reason you are unable to list what changes were made is that no changes were made. The well-established times for Earth's rotation and revolution and the moon's revolution and distances between the three objects guarantee a west-to-east eclipse every time. You're just too dumbass to understand any of it, with a pinch of desperation for any observation that doesn't fit the globe model to taste.
who the hell downvotes this? it's literally the easiest way to demonstrate the earth's revolution alongside the moon's orbit
Sorry, but it's impossible on heliocentric model.
Then why were we able to predict it’s exact path to the second? Hmmm.
@@JonasGrumby71 Hi!!! Bro Your earth is hollow/concave. Not, globe or a disc.
Hey guys, here is a great experiment. Just take your flash light, grab a golf ball, stand in front of a white wall (you could tape a map of the US there too). The wall represents America. The golf ball is the moon. The flashlight is the sun of course. Now raise the ball about 6 inches away from the wall. Turn on and point your flashlight towards the wall, passing from east to west (right to left), keeping the golf ball still, in one place, between the wall and the flashlight. The shadow of the golf ball will travel from west to east (left to right) or northwest to southeast depending on the angle you travel pass the ball. The truth will present itself. Its up to you to believe your own eyes or someone else.
VoysovReason Close! only one slight little error, the moon rotates around the earth every 29.58 days not 27. Thia ia only in passing but other than that, ya did good!
Brad Defoor you jebaited me into thinking that u are a flat earther, thank god not.
I am not a flat earther. My response was that he was off by 2 1/2 days. Was not putting him down but was helping in the next video that he makes.
Brad Defoor ik, thats what i was saying. Understandable misunderstanding.
Brad Defoor - Yes, you are right. It is 29.58 days relative to the sun, called a synodic month. That is the value that makes sense in this context. It is 27.32 days in relation to the distant stars, called a sidereal month. So that is where I got 27, but since we are talking about the moon relative to the sun, I should have used the synodic. Thanks. ;)
I was only trying to help, maybe I should have worded it better. But from the videos so far when dealing with the flat earth, you have done an awesome job in the information that you have given, keep it up!
In circular motion the angular velocity is calculated not linear where the formula is angular velocity is equal to linear velocity divided by radius from the center of the axis so earth angular velocity is 1800 km/hr divided by radius of earth which is 6300 which comes to 0.285 radians where as since moon revolves around the earth at 3400 km per hour at a radius from center of earth which is 380000 km its angular velocity will be only 0.009 which is much slower so please check this math and let me know if I am wrong. the moon revolves around the earth only 0.5 degrees per hour to complete 12 degrees in a day while earth at the same time moves 15 degrees around its axis so if we say the eclipse starts at point A than in one hour that point has moved 1800 kms to point B while moons has only moved 60 kms from point A which is 0.5 degrees of angular movement. I am sure you have not considered the main fact that circular motion goes on angular velocity not linear.
... but the Moon's shadow has no rotational or angular component around the Earth....
The FE clown car doesn't care. No matter how you explain it to them. I tried the same thing. They still can't wrap their head around it. So I went over all the Newtonian equations and the latitude at Goreville Illinois. They ignored those ones because there was math above the 7th grade level involved. Where will you be for the eclipse ?
Steven Baumann - I'm going to Oregon. Very excited.
VoysovReason I hope you have clear skies!
I'm gonna sleep when the other side will have all the fun :(
Quikee I'm sorry. Well. You could always come out there. If you have the means. All of us will post a lot of video for you.
Steven Baumann Hehe thanks. It's a bit late for that now, but I'm too busy anyway for an adventure like this. I'm looking forward too see the videos ;)
Uh, I don't think so.
If the earth rotates through 360 deg in 24 hours, that's 360 deg/24 hr = 15 deg/hr. If the moon completes a single orbit of the earth every 27.321 days, that's 360 deg/27.321 days = 0.549 deg/hr.
For the moon to "overtake" a point on the surface of the earth it would have to be orbiting at greater than 15 deg/hr, almost 30x faster than it's actual orbital speed. In other words, the moon would have to complete an orbit of the earth in less than 24 hours.
When analyzing rotational motion, the distance of the rotating objects from the axis of rotation comes into play.
The moon doesn't overtake a point on the surface of the earth, it's *shadow* does
Explained so simply. Another great video, even Flatards and Creationist should be able to understand.
Joe P. God makes me feel special. science offers you a way away from your demons😉
Sadly this is true. Just refer to Answers in Genesis Statement of Faith.
They will ignore any evidence that contradicts scripture. This really is lunacy. And they indoctrinate innocent children to believe the same nonsense.
It truly is sad.
Well good thing I wasn't indoctrinated into the faith, I found Jesus a couple years ago. No scripture specifies a flat or globe earth. Sounds to me like you're hiding your ignorance behind the mask of intellectualism.
Joe P. Read my above comment, it goes both ways though. People putting on their mask of ignorance just because they have faith in God, they think they don't need to understand how the universe works, just like people devoted to learning how it works but don't want to try and understand a spiritual life with God try and hide behind intellectualism. There's a road for both intertwined.
This video does NOT explain why. The real reason is that shadows move faster than objects when the shadow is cast over a great distance. When I place my hand over a light bulb, and cast my shadow a great distance on a wall per-say, a small movement of my hand will cause my shadow to move a great distance on that wall. The Earth's rotation over comes the moon's movement (360 degrees in 24 hrs vs 27 days) but it cannot over come the speed of the shadow.
I like the explanation but it still seems inconsistent that the shadow can move one way and yet the moon itself still travels the other way across the sky every day.
It's counter intuitive yes. I think that's why a lot of people go for the Flat Earth. Much of science is counter-intuitive and the full wonderment of reality is difficult to wrap one's head around unless they've been forced to work with this kind of logic in say, applied sciences. At that point, thinking and reading about things like this becomes a joy and you end up with a clear picture in your head of how the universe works. It's not a snowglobe.
Well, having been an engineer designing silicon chips for 25 years, I still don't have a clear picture of the shadow moving the opposite direction to the object.
chris4072511--not a flat earther--HOWEVER I am a nerd and search for truth. The shadow MUST GO WEST if the official model is correct. What is wonderful about this--we can through science do our own experiments and observations. There is no working model or observation that supports the solar eclipse explanation. Think of it this way. Picture the sun stationary as the model uses it and the Moon moving counterclockwise coming across the sun. (change this to test the hypothesis) Make the earth stand still--no rotation. Would the shadow 1.move east, 2. move west, 3. stay still? You can do your own experimentation. It will STAY STILL. NOW put a spin on the earth--what way MUST THE SHADOW GO?
So many incorrect statements here... You live on a planet called Hillbonio.
For a correct visualization of what really happened, here you go. It's painful to see people so grossly misunderstand something that's been fully understood and predicted for thousands of years. czcams.com/video/dgj--6EX-RE/video.html&t=9m15s
Furthermore, the shadow of the eclipse can actually turn and start going East to West if the shadow is close enough to one of the poles and is synchronous with the hemisphere which happens to be tilted toward the Sun. It's counter intuitive but I believe you can figure it out if you try hard enough.
The moon can never over take the earth at the speed of 2300 miles per hour while is at a distance of 330000 miles, sorry this is not math or science, this is gibberish.
"this is gibberish" the only factual point you made.
imagine moon is a airplane and it takes 30 days to circle the earth while earth has spun 30 times in the time I am sure the shadow is never even going to catch up lol
The moon's angular velocity is FASTER than Earth Rotation. You can test this easily. Go outside when the moon is in the sky and note the position of the moon, Wait 24 hours and go out at the EXACT same time as the day before. Note that the Moon is about 12 degrees ( a little more than a fist width at arms length) farther EAST than it was the night before. If you go out the third night at the same time the moon will be about 25 degrees farther EAST. Checkmate. The only reason that the moon appears to go west is because of the Earth's rotation.
Swinde,
No, moon's angular velocity is LESS (slower) than Earth's.
Moon's linear, or tangential speed is MORE (greater) than Earth's.
The rest you got correct.
Moon travels 2,200 mph...Earth's surface trave!s 800-1,000 mph (depending on latitude).
*VoySovReason* Moon and earth revolve and rotate counter clockwise but because we rotate *27/28* times faster than the moon orbits us thus it appears to move *east* to *west* on our sky. But on the day of that eclipse the shadow moved *west* to *east* which should only happen if the moon is noticeably faster than the earth's rotation which is what you explained very well.
But there's a flaw to your Logic every other time the moon revolves *west* to *east* (counter-clockwise) around the earth i.e (with no solar eclipse) still at around 2000mph approx just as you mentioned it rises *eastwards* and sails *westwards* even at the equator where speed is maximum.
Your answer to the question didn't put *previous observations* into consideration.
To put things clearly you didn't address the reason why the moon moved *west* to *east* on the day of the eclipse in contrast to why on every other day it moves *east* to *west* on our sky still at the same revolution speed even at places around the equator.
If it would help try simulating this in a 3d software. To better understand what I am talking about. Also in my simulation at exact scale of the sun,moon and earth' sizes and distances the moon's shadow seems diverging and bigger than the earth with the sun that big and far away(The shadow never converges to a small area on the sphere like it's supposed to). Well at least in blender.
* "To put things clearly you didn't address the reason why the moon moved west to east on the day of the eclipse in contrast to why on every other day it moves east to west on our sky" * - the moon didn't behave any differently that day. It was the _shadow_ of the moon, not the moon itself, which would have been observed as going East. How is that so hard for you to grasp?
The earth is flat. Period. Moon and sun same size. You'll see.
@idontthinkso I don't think so

Great explanation! Thank you. The problem with other expalnations on YT is that they are not to scale i.e. sometimes are very confusing
Then why are their eclipses that go other directions?
Rodriguez Rodriguez
That's because you don't understand how it works.
Go back to school.
Joe P They do? So why were all these mainstream science outlets adament about explaining why the shadow moves West to East during this eclipse, months beforehand while never making a point of it with other eclipses in the past?
School is the place were they dumbed us down.And from reading the comments,you and others are still on their carousel ball toy.Shooting around the sun, 30 times faster then a bullet.I bet you believe in santa claus too.Grow up.
Yeah its like a checkmate of sorts you would think.. honestly just one more on the endless list of discrepancies throughout the heliocentric model and its depiction of the moon, sun, and earth relationship.
Thierry Herreman. I bet you believe in other imaginary beings. Educate yourself.
You just contradicted yourself. You said the Earth rotates opposite of the Sun and the Moon, but when you explained why the shadow moves from West to East you showed the moon moving the same direction as the Earth.
Provide the exact source and statement.
This does not offer an explanation. It might explain why the shadow moves eastwards, but by that model we should then see the moon zooming across our sky, and we would see it pass over twice in a 24hr day. What he has not done in this model is rotate the Earth so that the shadow will move across the globe of the Earth Eastwards, but the surface will move westwards because the Earth is spinning. The moon can't be zooming by that fast, because in the sky it moves at an apparent speed just slightly slower than the sun. This model does not work and yet you are all applauding the effort! It does not fit with observations.
count69 - No, the moon does not pass over the earth twice in a day. You still don't understand it. The sun and moon only appear to be about 1/2 degree of width in our sky. That is called angular diameter. So to block to sun, and then unblock it, the moon only moves about 1 degree. That is only a tiny percentage of it's complete orbit, 1/360. So you are making a huge mistake thinking it has to move half of its orbit to block the sun. It doesn't. Again, the size of the moon orbit is 60 times bigger than the earth. Your claim assumes they are the SAME SIZE!
count69 - Yes, I noticed there are a lot of bad animations out there. I never found one that made it perfectly clear. I know you didn't say that it has to move half it's orbit to block the sun, but that is kind of the implication if you say it has to lap the earth twice in 24 hours. It seems you think it must move 180 degrees to pass it's shadow across the earth, or half it's orbit every day, but it doesn't, because it's orbit is so big. Almost no animations show the true scale of the earth and moon, because they look like small dots when you space them correctly. See my video "Proving the earth is not flat - Part 3 - The moon". In that video I show it to scale. The moon's orbit being 60 times the diameter of the earth is the key to understanding it. Only during a small part of it's orbit does the moon shadow hit the earth. The rest of the time, the moons shadow is missing the earth. So that is why it can move faster than the earth rotates, but still take about 29.5 days to make a full rotation. You can look up the distance of the orbit and given it's orbital period of 29.5 days, calculate it's speed. It works out to about 2288 mph.
count69 yip. If heliocentric theory is correct the earth is spinning faster than the moon can create a west to east casting shadow. It's path around the earth is so fast it's speed would only cast a shadow moving west to east if it were right outside what heliocentrists call the atmosphere
The Mad Flatter... We obviously and undeniably know that isn't the case. This guy did a great video on the moon explaining how it simply can't be 'close'. Simple observations by 2 people in 2 far apart locations easily show this (with no math needed). If your thoughts are the moon is right outside the atmosphere, can you humor me and watch it, if for no other reason but to explain why what he is saying could possibly be wrong?
But he hasn't explained the mechanics of the eclipse?
good job I read the comments section because I thought I was mistaken in thinking that the moon orbits is 29 days
just goes to show you should not believe everything you see on CZcams

+Peter Paul Donoghue,
Well...
There are two common ways to look at it.
...
1) Relative to distant stars (sidereal).
Sidereal month 27.321661 days (27 d 7 h 43 min 11.6 s)
2) Relative to the sun (Synodic), or new moon to new moon.
The synodic month is used to calculate eclipse cycles.
Because Earth has progressed in its orbit during the month, the moon must go a little bit farther along its orbit to realign with the sun.
Synodic month: Because of the moon's and Earth's elliptic orbits effects on the variations in angular rate,
the actual time between lunar phases may vary from about 29.18 to about 29.93 days.
The long-term average duration is 29.530587981 days (29 d 12 h 44 min 2.8016 s).
...
From Wikipedia
It can only work on a flat Earth map
+wes - Show us an illustration of how the path of the recent eclipse works on a flat earth map. Why did it not go parallel to the equator? Why doesn't it happen every month?
wes WROOONG
Plus, if you look at the actual path of totality, it starts in the northwest and ends up almost southeast (around Georgia). Does this work on the FE?
Wow, your math is completely wrong great job! If the earth goes around 27 days for the moon to travel around it once its spinning faster than the moon. the actual speed the moon and earth is traveling makes no difference, just the revolutions. You cant compare 24 hrs to 27 days and say the moon is traveling faster, that makes no sense. So there is no possible way the shadow can be cast from west to east. Oh, and you left out the earth is circling the sun.
it's just a COINCIDENCE SUN and MOON are DIFFERENT SIZES and DISTANCES yet EXACTLY SAME SIZE in our SKY! =D
Another pseudo-christian trying to prove God exists?
Yah, what is wrong with that guy, he should have been trained by now to not trust his own eyes. Only Science can tell you what you are looking at. He must be a Christian.
Yes, exactly right, it's a coincidence. Wasn't the case in the past, won't be in the future. Not a perfect coincidence though obviously, the apparent size of the moon varies by about 10% because it orbits the Earth in an ellipse as does the apparent size of the sun from the Earth's orbit which results in annular and total eclipses. Still, we're quite lucky I agree. Pity the moon is inclined by 5% from the plane of the solar system, that was unlucky, we'd get an eclipse every month if that were the case.
ps. you might want to get the caps lock on your computer looked at.
You left out the fact that the Earth also has to be at just the right distance.
Next you'll say it's just a coincidence that Earth has human life to see it. A coincidence it has water to sustain life; closer to the Sun water would boil away and further away it would freeze. A coincidence it has breathable air. A coincidence animals are born with DNA coding that allow some to survive alone right after hatching, sea turtles head for the sea. A coincidence plants have seeds to reproduce, photosynthesis, soil with minerals, rain, and animals to disperse the seeds, birds and bees and bats for pollination, and the balance of nature...Etc...Etc. Even evolutionist admit it's an all but unbelievable string of coincidences. There is a Nova special on it, I have it written down it somewhere.
Even many atheist have said evolution of humankind has such an infinitesimal chance of happening it could only happen once. Yet it would have to be twice, a male and a female, and they would have to happen along at the same time & place. No logical mind would believe it. But those programmed from childhood and who make it a personal matter will believe anything.
Jordan Pierce ""it's just a COINCIDENCE SUN and MOON are DIFFERENT SIZES and DISTANCES yet EXACTLY SAME SIZE in our SKY! =D""
No more of a coincidence than them actually being the same size and at the same distance.
In reality during a solar eclipse it depends on where the Moon is in it slightly eccentric orbit. Sometimes the Sun is totally blocked and sometimes it is not totally blocked. Due to the fact that the Moon moves in front of the Sun and the Sun is sometimes seen as being larger than the Moon during a solar eclipse one should then come to the conclusion that they are neither the same size nor the same distance away.
Wow thats amazing. I'm not very smart and this explained it so simply that I understood this concept. This is so exciting! I know I'm corny 😄
Michael Libert - Thanks, that's nice to hear.
You should do more videos of you picking up chicks at bars.
FINALLY! I've seen so many explanations online, both text and video, and none of them have managed click for me. I finally get it now! Thanks! :D
Right off the bat, this kid is confused by the counterclockwise rotation of the Earth. You cannot expect someone who has difficulty with something so elementary to even begin to grasp the concept of solar or lunar eclipses'. The instructor actually messed up by not clearly explaining that the moon does not "revolve", itself. It does however revolve around the Earth. When he says the moon is moving at 2000mph, he doesn't clarify that it isn't revolving itself at 2000mph. He makes a comparison between the Earth spinning at a little over 1000mph versus the moon flying through space at 2000mph. But he made it sound as if the moon is revolving itself at 2000mph. You MUST be more precise when explaining this to the next simpleton you attempt to inform. For the most part though, he's correct.
first , prove the earth rotates and we will go from there..
Bill, look up the Eötvös Effect.

I still don’t understand why people believe the earth is flat, why ??
Because their have truth.
@VoysovReason
I want to start this off by saying that I know that the earth is round. I also went to just south of St. Louis, USA, to experience the 2017 eclipse first hand. After the eclipse, i saw videos pop up with people asking why the shadow moved from west to east, so I thought about it for a few minutes.
IMO I'm sorry, but that was a terrible explanation. If I hadn't come up with my own, through observation, this video would have never been able to explain it to me.
So, here's how I figured it out. Now keep in mind, that this is from observations with my eyes, not taking into account the difference in sunset each night, or the position of the earth in its orbit. The conclusion is based on relative observations. I drive south after work at 11pm, so I see the southern night sky daily. (nightly?)
If you were go to outside every night at, lets say, 10pm and take note of the position of the moon in the sky, you will notice that the position of the moon each night is further to the east. So although, relative to the position of the sun, to the casual observer it might look as though the sun and moon take the same time to cross the sky, that is not true. From my simple observation, the moon "lags behind" the sun every night, moving further east relative to the sun. I had never actually thought about the direction of the orbit of the moon around the earth, but that simple observation confirms that the moon orbits the earth from west to east.
So therefore, because it rotates west to east, and because, relative to the sun, it is moving to the east, a shadow that it would cast on the earth would move from west to east.
The fact that the moon orbits at 2000mph and the surface of the earth rotates at 1000mph+ at the equator is NOT proof or explanation of why the shadow is moving west to east. Its throwing numbers at someone who doesn't know better, to improperly prove something. What if the moon were further out and orbited at only 500mph, its shadow could STILL move from west to east during a solar eclipse.
If any of this is incorrect, please let me know.
[Edit]
I edited out the part saying that the moon could orbit as slowly as once every 364 and still have the same effect. That's incorrect.
You are correct. You are explaining the same thing a different way. The actual speeds do not really matter, but the RELATIVE speeds do matter.
Can't watch now but I'm sure it will be great!
Im not a flat earther but this is just wrong to my common sense. If the earth is rotating around its axis at 1k mph and the moon is rotating around the earth at 2k mph then how come it can cast its shadow on earth west to east? Since it has to travel a huge distance in space while the earth is just spinning around its axis.
bigtbk3 Think of a line coming from the sun and touching the surface of the earth. The earth would spin past this line at 1000 mph. The moon would move through this same line at 2000 mph, from west to east . The moon outpaces the surface of the earth past this line, the line being the same as a light ray from the sun in this scenario.
The speeds are not an answer. What you see is the answer. You see the moon travel WEST. Are we to believe that when an eclipse happens--the moon speeds up? If you want to talk speed lets do it. The angular speed of the moon is faster than the earth--SO (we all AGREE). The RELATIVE SPEED of the moon to the surface of the earth is KEY. When you are looking at the moon--what way does it go across the sky? Toward the west. That means the moons speed RELATIVE to the earth is SLOWER. Hence the shadow MUST MOVE WEST. Since it does not--the OFFICIAL MODEL IS WRONG. LOVE THE TRUTH--STOP FIGHTING IT--BELIEVE SCIENCE--NOT SCIENTIST.
@TRUTHandLIGHT4809 Thank you you're right. These stupid people claim it was a great video and it wasn't.
you really should do more videos. I like them cause they are accurate yet clear. Please upload some more stuff, I also liked the ones about evolution.
I have this idea you're in a bar drunk as shit and you're sitting there explaining this.
No idea why...but I just do.
But now I get it,I was always stumped by this,I was sitting up awake last thinking about this too funny enough.
She says okay at the end there wow! So this must mean that everyone on the flat Earth sees the same Eclipse ? I don't think this is the case.
But wait, isn't things move slower if they away from a center??
It's the angular velocity of the Moon compared to the Earth that matters. The Moon has a greater angular velocity hence its shadow moves from west to east.
The angular velocity is irrelevant, because the Moon's shadow has no angular velocity.
You've got to bring out the crayons!!
Simple and convincing !
It's the lightsource that determines the direction of the shadow, the object has nothing to do with it, no matter how fast it's spinning! This makes no sense at all!
The phone ap "Day and Night Map" displays the position of the sun and moon at any particular date and time. Using this ap, the sun reaches the same longitude every 24 hours. The moon, however, reaches the same longitude every 24 hours and about 50 minutes. Thus, each of them revolve around the earth at their own speeds, and following a path that is somewhat similar. Since the sun's speed is greater than the moon's speed, the sun continually increases it's lead in front of the moon, until after about a month the sun catches up with the moon from behind.
Using this ap, I set the day to 8/21/17 and the time to the morning, advancing the time incrementally. On that day in the morning, the sun is behind (east of ) the moon, and both are southeast of the United States. By about 10am, the sun is close behind the moon, and gradually gains on the moon over the next 3 hours until the sun is in front of the moon.
If the sun is moving at a higher altitude than the moon, as the sun advances and passes the moon, a shadow would result. If the sun is slightly to the south of the moon as it passes, it would cast a shadow to the north, and the path of that shadow would follow that which is advertised for the solar eclipse on that day.
Thus, even though the "Day and Night Map" ap is shown on a globe earth model, it actually shows the movement of the sun and moon that is totally consistent with the Flat Earth model.
Exactly how did FE know we are about to have a solar eclipse again? No mention of it coming from any model I've seen. Must be magic that helio gets it right every time huh? Lunar eclipses too. FE response... A magical dark orb appeared and then vanished, because reasons.
When it is the eclipse, you see how the moon it's moving in the sky, and why it's not moving in the same way night??????????? Yeah, because it s night, riiiight???? Pfffff....
Very good video for 7 yearls old kids to explain them how it works.
The reason the moon's shadow moved west to east is the same reason absolutely everything's shadow on the surface of the earth moves west to east. It's the same reason your shadow moves opposite your direction of travel when you pass directly under a street light. =)
As beings of curiosity we spend our whole lives trying to figure out where we are and then we die! No one's getting out alive! And we are not on a spinning ball!
Let me turn your attention from the solar eclipse to the lunar eclipse. Why does the shadow in a lunar eclipse move from the top of the moon to the bottom?
Nick Sandt - Because lunar eclipses always occur near sunrise or sunset, so you are looking at it sideways. Here is a time lapse of the recent lunar eclipse I took in the early morning hours, in California. The orientation is exactly as I saw it, as the moon was setting to the west.

Voyce & Nick,
...
Uh... Wait a minute here, BatMan.
...
You can see a lunar eclipse at midnight if you live in the right place... The last one I watched was mid sky, not near the horizon.
...
The direction depends on BOTH your local viewing orientation, but also there is the fact that the moon's orbit is tilted 5 degrees off from the Earth-sun orbit (ecliptic).
...
For an eclipse, the moon must be crossing the ecliptic. This is where the earth-sun orbit and moon-Earth orbits cross. Those two planes intersect.
Graphic linked below...
Since the orbits cross, but are at a 5 degree angle at this point, it means the moon can be going somewhat northward or southward during the eclipse.
..
IF you happen to be facing more east or west, it can be moving left-right, or right-left as well. Flat Earthers would say that this is added complexity so as to confuse the peons, but geometry is geometry and simple to us smart-ass folks at the opposite end of the Dunning-Kruger Spectrum. (:-D).

Ahoy there Steve/Observ45er thanks for all the work that everyone at Challenger Center has done to inspire and motivate kids to learn about science. Keep up the great work. One student at a time. Apparently this is also how to solve the flat earth problem. It would be easier if they could just ask a question honestly. Had Nick just omitted his first sentence and would appear much more honest.
The Challenger Center must seem like the devil incarnate to Flat Earthers.
Ahoy Cap'n,
Have you been to one?
It quite literally looks like running another mission the way they are so engaged in the team oriented tasks. I work other activities like summer camps, after school 'club' and family science nights when there are activities more like the gold standard of Mr. Wizard to do. I pay attention to this stuff so I understand all the latest misconceptions as well as occasionally reading a good metaphor to explain things.

The earth is actually concave with a rotating celestial sphere but thank you very much for your work.
I'm open for debate. Try me.
here is a visual moving model reference of how it works czcams.com/video/5z5-9RAZbKE/video.html
Omg your missing the point. The moon is physically moving faster than the earth is rotating yes. BUT, you cannot forget that the moon takes 27+ days to orbit. 27+ rotations of the earth. The surface of the earth moves faster than the moon orbits. The earth will spin away from the shadow. It is going the wrong way. You are wrong sir.
You are missing the fixed light source (Sun), you are assuming the Sun is directly behind the Moon at all times. if the Sun was moving directly behind the Moon, your assumption would be true,
The Moon is moving through the ( earth size) light beam that is hitting the Earth, remember the Sun isn't moving.
FAKE... CGI
At 240,000 mile distance, the moon is orbiting the earth in 2000mph. Which is the same speed of 40mph if the moon were to be napping the earth. While the earth spins at 1000mph, so it is easily overtaking the moon. Thus on Globe model, the solar eclipse can only produce the path from west to east. See czcams.com/video/fqb0E9n65L0/video.html.
Put it another way. Earth' spin 360 degree / 24 hours = 15 degrees/hour. According to www.pas.rochester.edu/~blackman/ast104/moonorbit.html, the moon can only move 0.5 degrees/hour.
Thank you for a clear well illustrated answer to the question.

We could but bone heads won't understand.
I'm in Tennessee so I'm going to see it
wanna know what I Learned during the eclipse that it took the moon 90 mins to cross the USA and how fast it took to cover the sun lol
"Sounds Like Common Core Math to Me." :-) .. So, with that explanation of the Moon Moving From West to East .... and with the way things are getting crazier.. .Would This Not Make People Do Strange Things... like on a full Moon, and as we know the Moon's gravitational forces play in to the cycles.... I am just trying to wrap my head around the craziness of things we are seeing...
Thanks.
so we should the moon lapse the sun in your theory
Hello! very nice video. I am not a Flat earth velieber but i´ve been concern about that shadow trace. About the rotation of the earth and translation of the moon, rotation's earth is west to east and translation moonsi west to east as well, but because of the earth rotation speed we always see moon moving from east to west. the position of the moon relative to the sun will appear to cross the sky around 13.5 times faster than the sun east to west. I am still confuse
Brilliantly well put!
i don't really get it to be honest.. yes the speed is greater, but it shouldn't be moving greater from our perspective since we have to spin 27 times around for even one lunar orbit.. so how the hell does the moon appear to go faster when we are spinning faster than the moon is circling us? If they said the moon orbits in one day.. wouldn't that mean the moon would never move out of position from our perspective? It would have to be following the earth rotation exactly at the same point for it to be 1 orbit in 24 hours... So now if you say the moon takes longer than that... how the hell does that equal the moon traveling faster than the earth is spinning from our horizon.. ??
The moon’s orbit is about 60 times the diameter of the earth. So only a TINY portion of its orbit is a involved in the eclipse. It only moves a few degrees to sweep across the earth. Picture a bicycle wheel. How far do you have to spin the wheel for one spot on the tire to cross the hub? Only a tiny bit, not 180 degrees.
I still don't get it... If a plane is traveling parallel to me in the sky near my horizon and its traveling west to east at 500 mph... Even if i am spinning in a circle much slower west to east .. my perspective will always be approaching and passing the plane from my spin.. It has to, because my spin is happening faster than the plane is traveling across the sky regardless of the actual speed... im obviously not spinning 500 mph but i don't have to.. The plane will never over take my perspective and travel across my field of view as long as my spin is happening quicker than I am perceiving the plane.. h If you say the moon takes one day 24 hours to complete its orbit,, and the moon is right in front of me... the moon shouldn't move at all... It should remain in my line of sight... The spin would be equal to the rotation but im assuming that doesn't have to equal the same speed. I think there is something else to this... I think maybe it has to do with the angles in which the moon is orbiting..The elongated orbit.. Cause as its passing faster than ur spinning perspective its going in one direction longer as the earth spins in a giant elliptical loop. That is the only thing that could explain this.. because i can't see how something has to spin 27 times to one orbit and yet the moon travels faster across your horizon.. ur constantly passing the moon in ur rotation.. and if ur passing something ,,, it doesn't pass your perspective of it.. In my example that would mean the plane passing my perspective faster than i am spinning around in place.. thats impossible.
You're trying to compare based on rotational speeds, but the Moon's shadow has no rotational component around the Earth.
The shadow moves across the Earth/Moon system like a pencil rolling across a CD - it's a straight line, the extension of the line between Moon and Sun, it doesn't rotate around the Earth.
Clear?
When i talk about rotation, I mean the earths rotation... which gives us the perspective.. My mental block that I am having stems from the fact that the moon travels from east to west... So in my head im imagining something traveling from east to west would cast a shadow east to west because from our vantage point we are passing the moon with our rotation.. So my brain is thinking we should also pass the shadow east to west... I know I am wrong obviously and I know the reason for it that is explained in this video.. but for some reason I can't get a grasp of it logically.. I don't know why.. I think it has to do with the giant elliptical shape of the orbit that is confusing me. Because lets just say the moon circled the earth in a perfect circle and you connected a laser in a straight line from the moon to earth.. in order for the moon to stay in the same position = 1 orbit 24 hours, the moon would have to be traveling much faster than the rotation of the earth because it has to travel a greater distance to keep up with the rotation.. That laser beam should stay even on the surface not moving.... If the earths spin is faster than the moon can keep up with then the moon would start traveling east to west on our horizon... But what happens with the laser beam? The laser beam keeps moving west to east?
Guinea54 "When i talk about rotation, I mean the earths rotation... which gives us the perspective.. My mental block that I am having stems from the fact that the moon travels from east to west..."
No. If you're looking down on Earth and Moon from above, Earth is rotating anti-clockwise, and Moon moving around Earth anti-clockwise. So in pure compass points, the Moon is moving west to east, but since points on the Earth move faster in the same direction, the Moon moves across the sky, for an observer, east to west.
"So in my head im imagining something traveling from east to west would cast a shadow east to west because from our vantage point we are passing the moon with our rotation.. So my brain is thinking we should also pass the shadow east to west... I know I am wrong obviously and I know the reason for it that is explained in this video.. but for some reason I can't get a grasp of it logically.."
Stop thinking from the perspective of you on the Earth to start with. Look at it from above, draw a couple of circles on a piece of paper and imagine the sunlight coming from beyond the Moon circle. Draw a straight line to represent the Moon's shadow, as a continuation of the line from the sun. Before the eclipse, this shadow projects straight past the Earth, on its 'west' side, and after the eclipse, straight past on the East. It doesn't revolve around the Earth.
"you connected a laser in a straight line from the moon to earth.. "
No, don't do this, because the shadow is not rotating around the Earth, so the direction of this laser has no meaning
I may have to do a video on this....
Thank you VoysovReason.
Your explanation makes no sense! Everything you say is correct until you get to the end. The earth takes one day to complete the trip, the moon takes 27 days. So, how many times faster (than it currently moves) would the moon have to travel just to stay over your city? My calculation is 27 times faster. So if the moon currently moves at 2000 mph it would have to travel 27 x 2000mph= 54,000mph just to keep up. We know that that moon does not travel fast enough to keep up. That is why it appears to rise in the east and set in the west even though it is traveling in the same direction of the earth. There must be an explanation, but that is not it.
That's because earth is flat that's why these people will never be able to explain correctly why the shadow moves from west to east.

He just goes off that everything it’s far
We know according to the sphere model the moon is moving faster, granted. As we spin easterly one full 24 hour rotation the moon has only moved 1 step of its 28 steps it has to take (28 days). So basically after a day it hasn't moved much at all in its orbit around us.. So in our sky's it moves east to West as the sun does due to the speed of spinning earth.Its orbit and speed isn't really relevant as to how it moves across our sky's. EAST to West. The shadow would have to move east to West. It's the earth's movement that would create this if the sphere model is true. It's not but
no. the moon is moving twice as fast as the earth rotates but it has a much longer distance to go. so, yes, it appears not to move too much but the shadow is a direct projection of its speed onto the earth.
it's a bit like looking at a distant airplane and seeing that it appears not to move much across the sky but if there was a big long sick attached to the plane and reaching all the way down to you on the ground then it would smack into your at 500+ mph and smash you dumb fucking head to pieces.
it works a bit like that.
Do you even think before you write these ludicrous comments. Fuck man take the fuckin NASA tin foil hat off. Why not make the moon three times as fast as the rotating pear?? How bout 4 times as fast?? How bout make it 330000 miles away instead of 230000 miles away? How about take you big long "sick" and knock the moon out of your galaxy and stop the eclipse from happening...
Wait.. there are 2 moons now in the heliocentric lie? The moon is shrinking? The oblate pear is warming? We observe the moon is 230000 miles away? Are you sure the moon isn't made of cheese........
explanation makes sense when trying to explain the movement from west to east.. but can you show us that same explanation while showing us the moon rising from the east and setting to the west?
Syx7one Rulz The moon rises in the east for the same reason the sun does, the earth rotates from west to east so the east is the first part of an area to rotate around and face the moon.
I get that but a moon rising to the East doesn't answer the west to east shadow. His explanation shows the moon moving West to east that's why there's a shadow.... I'd like for him to show a rising moon moving from east to west with it's shadow moving West to east
Syx7one Rulz Sal Amander Think of it this way. Imagine an imaginary line from the sun to the earth. This represents the light from the sun. For the timespan of the eclipse the line is basically stationary. In 1 hour the earth's surface moves past the line at 1000 mph and would move 1000 miles. The moon in its orbit passes the same line since it is between the sun and earth. It is travelling at 2000 mph along its orbit. The moon will travel 2000 miles in the same hour that the earth moved 1000 miles. That is why the shadow goes from west to east faster than the earth's speed.
Another way to think of why there is a difference in direction is in sunrises and sunsets you are looking from the earth to the sky. The earth rotates towards the east, so that is why they rise in the east. The shadow of the moon is in contrast coming from the sun and moon, and the moon is travelling faster than the earth from west to east as explained above.

Syx7one Rulz - The moon rises in the east because we are on the earth rotating west to east. That is the predominant motion from our perspective.
the sine wave from the eclipse and jetstreams are unexplainable. UNTIL, you plot those same points on a flat earth map, then you see a circle which makes sense. peeps can't think
