I was having an inner crisis how we only see one side of the moon while it rotates around us while we rotate around the sun, I’m just having a hard time understanding how perfect things had to happen for us to only see one side.
this is hurting my brain, if it truly rotated it would show the other side at one point, so it's not rotating. it's just basically tethered on an orbit around the Earth. unless they changed the definition of rotating, this doesn't make sense. rotating means spinning 360° around its axis and it is NOT doing that
It is definitely doing that. If Moon didn't rotate on it's axis and say, if always faced the star Betelgeuse (i am sayibg this because now matter what time of the year, stars always stay in the same direction as always), after half a rotation around the Earth, it's back would be facing Earth and it's frobt would stilll face Betelgeuse but of course, this is not what happens because during the half rotation around the Earth, Moon also rotates on it's axis 180 degrees
Yep, it's another example of how you already need to know the answers before consulting anything on Internet. Besides your observation, the video graphics show a perfectly circular orbit around Earth, which is totally false.
@@Pimp-Master it is indeed not a true circle, orbits are a little more oval, but the sync locking effect is still the same, and gives the slight wobble we observe in timelapse images of the moon as well as the slight tilting of both earth and the moon.
If I side shuffle around a pole one time, always facing it, I would have made one rotation around my axis while completing one revolution around the pole. To see this in a clearer perspective, if the pole is going around me and I am always facing it I will have to rotate. The difference is, in the former my rotation is around a circle, in the former my rotation is at a point.
Take 3 balls and try to physically do a representation of this theory and be even more baffled. It makes zero sense. Also, according to the heliocentric model we should have a 12 hour light shift every month with 6am facing the sun at the start of the year and 6 months later 6 am is facing away from the sun. Again, take some balls, a soccer ball and tennis ball for example, and recreate the travel around the sun. The earth rotates 360 degrees in one day, and 1 degree on its orbit around the sun. So every day the earth faces the same direction every 24 hours. After 6 months the earth is halfway around the sun and 6 am is facing away from the sun as the sun has traveled 180 degrees in orbit, halfway around the sun. Food for thought.
@@shaikshoukath582 No, the Moon takes about 27.3 days to rotate once on its axis. That time equals the time taken for the Moon to orbit (revolve) around the Earth once.
At 2:15, the Earth is removed and the moon still rotates on the Earth's axis! It does not rotate on its own axis. If it would rotate on its own axis, then it would rotate like the Earth, but it doesn't. The animation shows this really clearly, no matter what the narrator says. If the moon would rotate around its axis, then at some point, somewhere on the Earth, day or night, we should see the dark side of the moon. That would be impossible to avoid. It just doesn't happen.
Dear Rotation itself involves circulating on its own axis And moon too definitely rotates on its own axis but the thing is that its period of rotation & revolution is almost same(27 days) That is why it's dark part doesn't appear to us
It does rotate on its axis. If the moon weren't rotating on its own axis, then we would be able to see both sides of the moon. Think about it. It's because the moon rotates on its own axis, taking the same time for a revolution around the earth, we see the same side. Try this taking two balls and one revolving around the other, while not rotating the revolving ball on its axis, and you'll understand.
@@dimlighty i have an experiment for you too. Take an orange and shove a chopstick in it. Hold the chopstick by the other end and rotate it around yourself. Just do a few spins. You'll see that the orange will behave just like the moon in relation with the earth. You'll only see one side of it, the one with the chopstick. Then you'll realize that the orange it's not actually rotating around its axis, it basically can't, because it's constricted by the chopstick, just like the Earth's gravity constricts the Moon. The rotation axis of the orange is you, not the center of the orange.
@@sethsavage3532 I tried it, I got your point. But how would you explain this?: The Earth takes 24 hours to rotate on its axis while the Moon revolves around the earth in approx. 28 days. If we were to consider your explanation correct, then then the moon would always be in the sky when seen from the side of the earth which the moon would face. Your explanation just won't fit here.
I have watched tons of videos and explanations on this but I still fail to understand how nobody anywhere on earth don't ever see the other side of the Moon.
haha. the moon does not actually rotate. we don't have to believe in the stupid theory of the rotating moon. If the moon rotates, of course we have seen the back of the moon.
This video, like all the others, only adds to the confusion many people have because it ignores the facts that the moon is tilted 1.5 degrees and its axis always points in the same direction and does NOT turn during its revolution. As a result of showing NO tilt, from 1:38 on it looks like the moon is just being pulled around earth without rotating - even though it actually IS rotating (relative to its imaginary, non-turning axis). If those two details were clearly shown, it would be clear that the moon must rotate to keep the same face toward earth.
I don't know why, even after watching and replaying the explanation a few times, I still struggled to comprehend; but then it finally clicked, so if you're still struggling like I was, here's my "click" moment: Yes, the moon has to show its backside at some point; but by then it's moved to the opposite side of the earth. So if the moon's backside is pointing "up" at the "top" of its trip around Earth, then by the time it spins fully (backside pointing "down"), it's also coincidentally traveled to the "bottom" of its circle around Earth. So... it tries to "moon" us but it doesn't realize we're no longer there. 😜
Alternatively, you could have simply said that the moon's period of rotation coincides with the amount of time it takes to orbit the earth. This is known as synchronous rotation and is why the same side of the moon always faces earth.
@@sailorman8668 For some reason though, that wasn't enough. I kept thinking "yeah but the moon HAS to turn around, so why don't we ever see it?!?!" It didn't click with me that the synchronous rotation/revolution meant that our relative positions were always in flux.
2:27 Wrong! The Far Side of the Moon is not always dark. During a New Moon, when the Near Side is dark or almost completely dark, the Far Side is fully lit up and is not the Dark Side any more. So we should call them Near Side and Far Side, and recognize that their lighting changes over the month.
So many things still do not add up about the moon and its movements. For instance sometimes the moon goes the same way as the sun and other times it goes a lateral way of the sun. I watch the moon whenever visible that's why it doesn't make any sense to me. It seems to me like it's being piloted by some type of being.
If the moon rotates on its axis, then we would see the backside of the moon. Showing a line running to the moon shows rotation around earth, but not the spin on its axis. If the moon spins, physics, would show all of the moon surface at different points on earth. Two spinning orbs at different speeds of velocity don't sync. Even your video shows that if the tethering ball was connected to the string that their isn't a spin on the ball. The string would wrap around the ball.
This is what I struggle with. For no point on earth not to see the other side of the moon means to me that the moon does not spin on its axis. However everyone says it spins once every moon rotation around the earth. I have set up models and no matter where the moon axis is, if it spins we should see other parts of the moon within those 28 days of rotation
@@b577960 : your setup is wrong, or incomplete. You need to think of your moon with a stick of something for its axis. That stick doesn’t rotate so if you have a stick make a mark in it and be sure never to rotate the stick Then run your demo and see if the “moon” keeps the axis mark in the same place or not. It realize writing this down may not be Really clear. Sorry.
Kit- thanks for getting back to me- I actually did stick a toothpick in my mandarin and I kept it steady as I rotated it around my apple. You are right, if the moon did not spin then I would see the other side. If it rotated once ion 28 days I would not see the other side. Thanks
Do you have any idea what I went through the past hour just trying to imagine what it looks like when I searched google how we only see a part of the moon's side 🙉 Anyways, thanks for this excellent visualization and explanation! Really really really appreciate it!
This video is good in graphics but it doesn’t NOT make sense as the moon takes 27 days, 7 hours and 43 seconds to revolve around the earth. It DOES NOT revolve at the same speed than earth’s rotation as shown at 1:39 🤷🏻♀️so yeah it looks like pretty much we have no idea how it actually works?
If I side shuffle around a pole one time, always facing it I would have made one rotation around my axis while completing one revolution around the pole.
Hold a can/cup in front of you and spin around once and the can/cup that was always facing you will have done one rotation. You will also notices that the back of the can/cup will have faced all the walls as you spin around, so you know the can/cup is rotating, its just not rotating on the spot.
For those at are struggling to understand that a single moon rotation is required in order for us to not see the other side of the moon. Put a toothpick through a mandarin and grab an apple. Moon is mandarin and apple is the earth. Put the toothpicked mandarin on the table and don’t touch it. Let’s for the sake of understanding we make the apple rotate around the mandarin. You see that apple (earth) can see all sides of the moon as it rotated around the moon. This means that the moon must rotate on its axis once every 28 days. Now go back and make the earth (the apple) the centre and the mandarin (with the toothpick) rotate around the apple. Keep the toothpick always in the horizontal position as it rotates around the earth. This is the case if the moon did not spin on its axis. You can see that the earth would see the other side of the moon. This means that the moon must spin on its axis once every full revolution around the earth. So why does it only spin once? The reason is that the earth’s gravitational pull on the moon is stronger on the close side and weaker on the far side. This means that the gravitational centre of the moon is not in the middle of the moon but is off centred from the moon’s axis and is closer to the earth side of the moon this means that the majority of the moon’s mass is further away from this gravitational centre. Therefore as the moon is rotating around the sun the centrifugal force will throw the greater mass to the far side of the rotation, and therefore we on earth only see one side of the moon. I hope this makes sense to everyone
In addition. I would like to add that the moon’s rotation is more like a tethered rotation around the earth. In much the same way as those old line controlled flying aircraft with you in the centre. The motor is creating the centrifugal force that equals the gravitational pull (the lines going back to you in the centre). On these model planes you only get to see one side of the plane, that’s because the greater mass (weights added on far wing) is on the far side wing half. I hope this makes sense to everyone
IKR, I honestly think he'd have double the subbed if he voiced the videos himself unless he sounds like a smurf, but then again some people are into that!! 🤔😆
time required for one full rotation = time required for one full rotation Should watch the video and correct it before making it public. Nothing worse than mistakes in a video that's meant to teach. Time in video of what I'm talking about is at 45 seconds.
The graphic is not wrong. The time of One rotation of its rotation is equal to the time of One rotation of its revolution. I think you are getting mixed up because of what he says not what the pics are. Nothing worse than a wrong comment. LOL
For all the people saying the graphic is wrong at 0:45 understand that it is not. Forget Rotation and Revolution for a second and imagine the pics are of a Cat and a Dog. The time for One full Rotation of the CAT is equal to the time of ONE full Rotation of the DOG. See now.
@@alexfarias5156 when you start to investigate this, everything is very strange....earth should be lit on only one side like the moon, it doesent add up.
I know! The moon seems to manage keeping one face aimed at Earth even through orbital speed ups and slow downs, so why can't it always be a full moon too? Geez, this thing can pull off any stunt.
Wait a minute, they say the moon orbits the earth anti-clockwise. But why do i, right now see the moon going clockwise (west to east?) that doesn't make any sense.
no idea what you're talking about. In this video, the rotation of the moon on it's axis, and the revolution of the moon around the earth, are both going anti-clockwise. West to East is anti-clockwise. On a clock face - 12 is North. 3 is East. 6 is South. 9 is West. In this example the moon goes from 12 (North) to 9 (West) to 6 (South) to 3 (East) and back to 12 (North) around the Earth. That IS anti-clockwise.
Very Very great video but my question here is why there is no tidal Locking between the earth and sun and what if their was tidal locking between earth and the sun then only one part of the earth will get light from the sun.
yeah, this is all great and stuff. but the odds that it has an infinite "axis" to rotate around. we just assume the only one there is, is left to right or right to left. but it could have been up and down or down to up. or anything in between. The fact all of these are zero and always faces us is beyond comprehension in odds. someone parked it there makes more sense than anything else.
@@julien.le.createur that is the "created" explanation. but doesnt apply to any other freaking satellite known to man. and not only that. if "1:47" were true, it wouldnt create a "same face" moon, but a severely wobbly one. and also, how long would it take to do what you claim? i thought it was a chunk of earth as science stated. or is it not.... but yet its not made off the same % of material.... what a joke.... also, your 1:47 explanation is just the center of mass. this in fact would NOT stop it from having a rotational speed difference than the mass that is "pulling" on it... the moon would just have a visual wobble, just like an unbalanced tire. pulling on the center of mass has ZERO affect on moments of intertia... its sad that people fall for such chitty physics

because all of this is a lie... they lied in the beginning of heliocentric, so when questioned about things like these, they have to create more and more "facts" One of the newest things they've invented is the Moon is IN the Earth's Atmosphere...
Because the reason the moon is tidally locked with Earth has to do with differences in the gravitational force between the Earth and moon. With human-sized objects, this doesn't matter, but with something well over 2,000 miles across - it makes a difference. The force of gravity gets weaker as you get farther away, so the difference in the force between the Earth and the side of the moon facing Earth - the the opposite side varies by 2,000 miles. The total distance to the moon is 240,000 miles or so. While small, it is a difference of about 0.8%. Over millions of years, this adds up. For the Earth regarding the sun, the Earth is about 8,000 miles across, but the sun is 93 *_MILLION_* miles away, so the difference in the gravitational force on opposite sides of Earth relative to the sun is tiny. 0.008%. The variance is 1/100th of what it is for the moon. Add on to this the fact that the Earth is also much more massive than the moon, so this variance has a much lesser effect on the Earth. This is why the Earth is not tidally locked with the sun. The tidal forces on the Earth from the moon are actually more significant than from the sun - and the Earth is indeed slowing down for this very reason, but due to the lesser variance - and more mass - it just doesn't have the same effect. This is how educated people answer your question. Uneducated morons respond with "because all of this is a lie". I'll let you decide which answer to accept.
@Dev Guy I understand the science behind it. That's the point of science. I don't just blindly accept it. I understand how tidal forces work - namely the gravitational gradient that occurs with large celestial bodies due to the inverse square law that gravity demonstrably follows and how that demonstrable gtadient interacts with those celestial bodies. The same phenomenon can be observed with just about every other moon in our solar system with regards to their parent planets (they too are tidally locked into synchronous orbit about their parent planets). So the answer to your question is a resounding yes. The irony of your argument is that you are the one blindly rejecting the explanation because you do NOT understand the science. You think that gives you carte blanc to just reject that which you don't understand and accuse others of blindly accepting it. To those that DO understand it, you might as well be accusing us of blindly accepting that fire is hot. Because science. That's how utterly stupid you sound to us.
If We see only one side of the moon so does the rest of the Universe, so please explain how does it Rotate from the Earth's prospective and from the other prospective of the universe
So does it mean that if I were on the surface of the moon, on the moon's equator, if I pedaled my bicycle towards the sun setting on the horizon, I would experience an eternal day since 17 km/h would be enough to compensate for its rotation?
We only "see" one side of the moon (which is shined by the sun). But, the side which faces the earth is not always the same side. Human is just restricted with their own senses.
The animation does not show the moon rotating on its axis. Where its axis should be is on the diagram it actually shows the face that always faces earth, except its facing upwards, towards the viewer. Also the earth shown here is spinning on its axis (which is apparently goes through Papua New Guinea). Pretty confusing for a supposedly educational video.
So if you were living on the moon, then there wouldn't be one side that is always in darkness. It just appears that way to us because of the tidal locking. Interesting.
Earth's Moon" - NASA Solar System Exploration is an even better depiction of a "Real Time" model and it shows a wobble because there are extenuating issues both other gravitational forces and the tilted axis of both earth and moon relatively speaking. This still provides a unique opportunity of having a tower pointing thousands of KM in length towards each celestial object which in an isotropic field can provide statical charged area's that could be harnessed like Nicola Tesla tried to harness. Also Hyper Loop space travel would sling shot ships into many different directions without in efficient rocket propulsion. The future benefits of this have yet to be realized. Oh how we are such cave men and women still in this day and age. AI will see this come about before my idea is realized.
Picture in your mind an elevator not only towards the earth without connecting but reaching a gravitational balancing point it will not be earth's geostationary orbit but a significant distance to the earth. This elevator will not just be an elevator more like a induction tube connected too the moon and then through the moon at different angles with different tube outlet tube/elevators in what ever direction one would want to launch a space vehicle or probe. sling shot too anywhere using the rotation of the moon as our immediate so called "wormhole" there is so much future potential alignments of gravitational pull to reach high speeds, for different objectives. I do not think anyone else has thought of that yet.
But the moon is apparently moving further away from us each passing year but by bit, so wouldn’t the gravitational force weaken bit by bit and lead to a different speed of rotation and orbit, leading to see more of the other typically unseen sides of the moon? The side where the aliens or the military bases are that is lol?
So it's a unic characteristic of the moon but all the other moons are moving in the same way (?!) The side we can not see it's called the far side of the moon, not the dark side.
But gravity is not a force according to GR, so what keeps the tidal locking? It is said that 59% of the moon is visible from the earth, imagine an arc 59% of the moon's circumference and in the middle of the arc a point m and lies in the imaginary line passing between the centers of the moon and the earth. After a quarter revolution, the point m is already off the line and remains off the line on half revolution and soon. So how can you you say that the same side is facing towards earth?
Gravity is curvature of space-time according to GR, and effect of curved space time is the same as the effect of gravitational force in Newtonian model, on macro scale, and speeds far away from speed of the light. It is 59% of total amount of Earth surface visible from Earth, but not at once, but during the period of one orbit of the Moon, so your example has no sense at all.
The moon is not "locked" in any way whatsoever. The narrator is convinced that the moon could have changed its rotation, but over 4 billion years has proved him (it) wrong.
I have this doubt about this. @1:47, When Moon rotates, why the centre of gravity also rotates. As I understand, The reason why centre of gravity is different from centre of mass is due to varying gravity of Earth, right? If it is so, even when moon rotates, centre of gravity should notchange, right? OK. Got it from the video given below. czcams.com/video/kcdrgPVXgxA/video.html There is a bulge produced in the surface of moon and it happens due to that.
చంద్రుని (ఉపగ్రం) యొక్క centre of gravity , చంద్రుని యొక్క వృత్తము యొక్క centre లో ఉండదు. ఎందుకంటే, భూమి యొక్క ఆకర్షణ శక్తి లో, చంద్రుని యొక్క ఆకర్షణ శక్తి, 6 వ వంతు మాత్రమే. అందుకే centre of gravity చంద్రుని లో ఒక వైపుకు ఉంటుంది.
Great content thanks 👍 quick question if the Moon alignment change is rectified by the earth why is The moon is moving away from Earth at a rate of 3.8 centimeters (1.5 inches) per year. So what I believe is all the satellites on tied to any planet has equal impact of gravitational force from both Sun and the Planet itself to its own Satellite and the Sun being more stronger can have an impact on the Satellite of the planets too... Let me know your thoughts ??
@@fauxreal9739 Literally, the only way physically possible for us to see the same side of the moon is if the moon is rotating. There's literally no other explanation.
I am sorry, but your explanation is incomplete. You explained tidal locking but did not explain why it happens. Tidal locking happens because the moon is a deformable body, and because of Earth's gravitational tidal force, it deforms to become an ellipsoid. Tidal forces are the stretching forces due to the difference in gravitational force between two points. The region of the moon closer to Earth will experience greater gravitational force than the one further away. This distorts the moon from a sphere to an ellipsoid. This slight bulge of the ellipsoid is closer to Earth, so it has more force of attraction; hence, it is forced to always point towards Earth. That is the main reason for tidal locking. This deformation of the moon is crucial in understanding tidal locking because a perfectly rigid sphere cannot get tidally locked. I have avoided the technical details of how deformation for the moon comes at an expanse of its rotational energy (or speed of revolution, depending on which has less period). This syncs the period of revolution with the period of rotation.

This video, like all the others, only adds to the confusion many people have because it ignores the facts that the moon is tilted 1.5 degrees and its axis always points in the same direction and does NOT turn during its revolution. As a result of showing NO tilt, from 1:38 on it looks like the moon is just being pulled around earth without rotating - even though it actually IS rotating (relative to its imaginary, non-turning axis). If those two details were clearly shown, it would be clear that the moon must rotate to keep the same face toward earth.

I'd like to see if someone finally make this version, with tilted moon
To top it off, the earth is said to be traveling through our galaxy at 490,000 mph! That means the moon is also traveling at the same speed.

I don't know why, even after watching and replaying the explanation a few times, I still struggled to comprehend; but then it finally clicked, so if you're still struggling like I was, here's my "click" moment:
Yes, the moon has to show its backside at some point; but by then it's moved to the opposite side of the earth. So if the moon's backside is pointing "up" at the "top" of its trip around Earth, then by the time it spins fully (backside pointing "down"), it's also coincidentally traveled to the "bottom" of its circle around Earth.
So... it tries to "moon" us but it doesn't realize we're no longer there. 😜
Alternatively, you could have simply said that the moon's period of rotation coincides with the amount of time it takes to orbit the earth.
This is known as synchronous rotation and is why the same side of the moon always faces earth.
@@sailorman8668 For some reason though, that wasn't enough. I kept thinking "yeah but the moon HAS to turn around, so why don't we ever see it?!?!"
It didn't click with me that the synchronous rotation/revolution meant that our relative positions were always in flux.
This should have way more views
2:27 Wrong! The Far Side of the Moon is not always dark. During a New Moon, when the Near Side is dark or almost completely dark, the Far Side is fully lit up and is not the Dark Side any more. So we should call them Near Side and Far Side, and recognize that their lighting changes over the month.
no one is exactly right in this world, where newton's theory was wrong then we are always wrong, thank you for your note
Amazing video! Thanks a lot for imparting this valuable knowledge
Nice explanation
So many things still do not add up about the moon and its movements. For instance sometimes the moon goes the same way as the sun and other times it goes a lateral way of the sun.
I watch the moon whenever visible that's why it doesn't make any sense to me. It seems to me like it's being piloted by some type of being.
The moons orbital plane is differ than that of the earth around the sun.
If the moon rotates on its axis, then we would see the backside of the moon. Showing a line running to the moon shows rotation around earth, but not the spin on its axis. If the moon spins, physics, would show all of the moon surface at different points on earth. Two spinning orbs at different speeds of velocity don't sync. Even your video shows that if the tethering ball was connected to the string that their isn't a spin on the ball. The string would wrap around the ball.
This is what I struggle with. For no point on earth not to see the other side of the moon means to me that the moon does not spin on its axis. However everyone says it spins once every moon rotation around the earth. I have set up models and no matter where the moon axis is, if it spins we should see other parts of the moon within those 28 days of rotation
@@b577960 : your setup is wrong, or incomplete. You need to think of your moon with a stick of something for its axis. That stick doesn’t rotate so if you have a stick make a mark in it and be sure never to rotate the stick
Then run your demo and see if the “moon” keeps the axis mark in the same place or not.
It realize writing this down may not be
Really clear. Sorry.
Kit- thanks for getting back to me- I actually did stick a toothpick in my mandarin and I kept it steady as I rotated it around my apple. You are right, if the moon did not spin then I would see the other side. If it rotated once ion 28 days I would not see the other side. Thanks

Wow. Everything is so crystal clear due to this cartoon. How could I ever doubt this story? Science knows everything, bah bah bah.
Welcome Sumit Sir ke students 😁😁
This video is good in graphics but it doesn’t NOT make sense as the moon takes 27 days, 7 hours and 43 seconds to revolve around the earth. It DOES NOT revolve at the same speed than earth’s rotation as shown at 1:39 🤷🏻♀️so yeah it looks like pretty much we have no idea how it actually works?
Why doesn't that happen to the Earth due to the sun's gravity?
you are asking the right question
@@rockwithyou2006 Any official answers?
Exactly. NASA is a religion
Bcaz earth is far away and doesnt affected by his tidal locking by sun due to weak gravitational force
Because the heliocentric model is made up nonsense
Gem
If I side shuffle around a pole one time, always facing it I would have made one rotation around my axis while completing one revolution around the pole.
in fact, they could come from anywhere in Europe, not just Poland
Will you please tell me the name of the background music at the end of the video at 3:14
Hold a can/cup in front of you and spin around once and the can/cup that was always facing you will have done one rotation. You will also notices that the back of the can/cup will have faced all the walls as you spin around, so you know the can/cup is rotating, its just not rotating on the spot.
For those at are struggling to understand that a single moon rotation is required in order for us to not see the other side of the moon. Put a toothpick through a mandarin and grab an apple. Moon is mandarin and apple is the earth. Put the toothpicked mandarin on the table and don’t touch it. Let’s for the sake of understanding we make the apple rotate around the mandarin. You see that apple (earth) can see all sides of the moon as it rotated around the moon. This means that the moon must rotate on its axis once every 28 days. Now go back and make the earth (the apple) the centre and the mandarin (with the toothpick) rotate around the apple. Keep the toothpick always in the horizontal position as it rotates around the earth. This is the case if the moon did not spin on its axis. You can see that the earth would see the other side of the moon. This means that the moon must spin on its axis once every full revolution around the earth. So why does it only spin once? The reason is that the earth’s gravitational pull on the moon is stronger on the close side and weaker on the far side. This means that the gravitational centre of the moon is not in the middle of the moon but is off centred from the moon’s axis and is closer to the earth side of the moon this means that the majority of the moon’s mass is further away from this gravitational centre. Therefore as the moon is rotating around the sun the centrifugal force will throw the greater mass to the far side of the rotation, and therefore we on earth only see one side of the moon. I hope this makes sense to everyone
In addition. I would like to add that the moon’s rotation is more like a tethered rotation around the earth. In much the same way as those old line controlled flying aircraft with you in the centre. The motor is creating the centrifugal force that equals the gravitational pull (the lines going back to you in the centre). On these model planes you only get to see one side of the plane, that’s because the greater mass (weights added on far wing) is on the far side wing half. I hope this makes sense to everyone
I now have more questions than answers 😮💨

time required for one full rotation = time required for one full rotation Should watch the video and correct it before making it public. Nothing worse than mistakes in a video that's meant to teach. Time in video of what I'm talking about is at 45 seconds.

Thank you so much. I'm reading Rocket Men about the Apollo 8 mission & was having a hard time remembering/understanding how this worked
Great! Wonderful content. Where is the video about phases?
I know! The moon seems to manage keeping one face aimed at Earth even through orbital speed ups and slow downs, so why can't it always be a full moon too? Geez, this thing can pull off any stunt.
Wait a minute, they say the moon orbits the earth anti-clockwise. But why do i, right now see the moon going clockwise (west to east?) that doesn't make any sense.
no idea what you're talking about. In this video, the rotation of the moon on it's axis, and the revolution of the moon around the earth, are both going anti-clockwise. West to East is anti-clockwise. On a clock face - 12 is North. 3 is East. 6 is South. 9 is West. In this example the moon goes from 12 (North) to 9 (West) to 6 (South) to 3 (East) and back to 12 (North) around the Earth. That IS anti-clockwise.
Very Very great video but my question here is why there is no tidal Locking between the earth and sun and what if their was tidal locking between earth and the sun then only one part of the earth will get light from the sun.
yeah, this is all great and stuff. but the odds that it has an infinite "axis" to rotate around. we just assume the only one there is, is left to right or right to left. but it could have been up and down or down to up. or anything in between. The fact all of these are zero and always faces us is beyond comprehension in odds.
someone parked it there makes more sense than anything else.

what a joke....
also, your 1:47 explanation is just the center of mass. this in fact would NOT stop it from having a rotational speed difference than the mass that is "pulling" on it...
the moon would just have a visual wobble, just like an unbalanced tire. pulling on the center of mass has ZERO affect on moments of intertia...

There is no dark side of the moon, really. Matter of fact, it's all dark. -Gerry O'Driscoll
It was so interesting!
Wow !!!.....wowww....
why does not earth have synchronous rotation when it rotates around the sun ?
because all of this is a lie...
they lied in the beginning of heliocentric, so when questioned about things like these, they have to create more and more "facts"
One of the newest things they've invented is the Moon is IN the Earth's Atmosphere...
Because the reason the moon is tidally locked with Earth has to do with differences in the gravitational force between the Earth and moon. With human-sized objects, this doesn't matter, but with something well over 2,000 miles across - it makes a difference. The force of gravity gets weaker as you get farther away, so the difference in the force between the Earth and the side of the moon facing Earth - the the opposite side varies by 2,000 miles. The total distance to the moon is 240,000 miles or so. While small, it is a difference of about 0.8%. Over millions of years, this adds up.
For the Earth regarding the sun, the Earth is about 8,000 miles across, but the sun is 93 *_MILLION_* miles away, so the difference in the gravitational force on opposite sides of Earth relative to the sun is tiny. 0.008%. The variance is 1/100th of what it is for the moon. Add on to this the fact that the Earth is also much more massive than the moon, so this variance has a much lesser effect on the Earth. This is why the Earth is not tidally locked with the sun.
The tidal forces on the Earth from the moon are actually more significant than from the sun - and the Earth is indeed slowing down for this very reason, but due to the lesser variance - and more mass - it just doesn't have the same effect.
This is how educated people answer your question. Uneducated morons respond with "because all of this is a lie". I'll let you decide which answer to accept.
@Dev Guy I understand the science behind it. That's the point of science. I don't just blindly accept it. I understand how tidal forces work - namely the gravitational gradient that occurs with large celestial bodies due to the inverse square law that gravity demonstrably follows and how that demonstrable gtadient interacts with those celestial bodies. The same phenomenon can be observed with just about every other moon in our solar system with regards to their parent planets (they too are tidally locked into synchronous orbit about their parent planets). So the answer to your question is a resounding yes.
The irony of your argument is that you are the one blindly rejecting the explanation because you do NOT understand the science. You think that gives you carte blanc to just reject that which you don't understand and accuse others of blindly accepting it. To those that DO understand it, you might as well be accusing us of blindly accepting that fire is hot. Because science. That's how utterly stupid you sound to us.
@Dev Guy Why you waste your time with brainwashed ignorants who believe everything they are told.....
@Dev Guy I would like PROOF that the Moon actually has an axis that it rotates around. I want to see a flag planted on the surface or something.
That is Good explaining 🌺
If We see only one side of the moon so does the rest of the Universe, so please explain how does it Rotate from the Earth's prospective and from the other prospective of the universe
So does it mean that if I were on the surface of the moon, on the moon's equator, if I pedaled my bicycle towards the sun setting on the horizon, I would experience an eternal day since 17 km/h would be enough to compensate for its rotation?

@@fromnorway643 Yes.
@@salmaniqbal6091 I'd assume it's under "cheapest possible music we could use that won't trigger a copyright strike."
We only "see" one side of the moon (which is shined by the sun).
But, the side which faces the earth is not always the same side.
Human is just restricted with their own senses.
No, only one side faces Earth.
That is COMPLETELY wrong.
The same side of the moon always faces earth.
We NEVER see the other side.
how other moons behave?
The animation does not show the moon rotating on its axis. Where its axis should be is on the diagram it actually shows the face that always faces earth, except its facing upwards, towards the viewer. Also the earth shown here is spinning on its axis (which is apparently goes through Papua New Guinea). Pretty confusing for a supposedly educational video.
So if you were living on the moon, then there wouldn't be one side that is always in darkness. It just appears that way to us because of the tidal locking. Interesting.
Earth's Moon" - NASA Solar System Exploration is an even better depiction of a "Real Time" model and it shows a wobble because there are extenuating issues both other gravitational forces and the tilted axis of both earth and moon relatively speaking. This still provides a unique opportunity of having a tower pointing thousands of KM in length towards each celestial object which in an isotropic field can provide statical charged area's that could be harnessed like Nicola Tesla tried to harness. Also Hyper Loop space travel would sling shot ships into many different directions without in efficient rocket propulsion. The future benefits of this have yet to be realized. Oh how we are such cave men and women still in this day and age. AI will see this come about before my idea is realized.
Excellent video
Finally I understood
The sun is moving through space and we are following it while rotating and going around it.
Picture in your mind an elevator not only towards the earth without connecting but reaching a gravitational balancing point it will not be earth's geostationary orbit but a significant distance to the earth. This elevator will not just be an elevator more like a induction tube connected too the moon and then through the moon at different angles with different tube outlet tube/elevators in what ever direction one would want to launch a space vehicle or probe. sling shot too anywhere using the rotation of the moon as our immediate so called "wormhole" there is so much future potential alignments of gravitational pull to reach high speeds, for different objectives. I do not think anyone else has thought of that yet.

Dammit music so scary, so creepy!
Typo at 0:47! The second rotation should be revolution. Hope that helps! :)
But the moon is apparently moving further away from us each passing year but by bit, so wouldn’t the gravitational force weaken bit by bit and lead to a different speed of rotation and orbit, leading to see more of the other typically unseen sides of the moon? The side where the aliens or the military bases are that is lol?
So it's a unic characteristic of the moon but all the other moons are moving in the same way (?!)
The side we can not see it's called the far side of the moon, not the dark side.

But gravity is not a force according to GR, so what keeps the tidal locking? It is said that 59% of the moon is visible from the earth, imagine an arc 59% of the moon's circumference and in the middle of the arc a point m and lies in the imaginary line passing between the centers of the moon and the earth. After a quarter revolution, the point m is already off the line and remains off the line on half revolution and soon. So how can you you say that the same side is facing towards earth?
gravity is not a force only on a technical level. For 99% of applications, we can treat it like a force.
Gravity is curvature of space-time according to GR, and effect of curved space time is the same as the effect of gravitational force in Newtonian model, on macro scale, and speeds far away from speed of the light.
It is 59% of total amount of Earth surface visible from Earth, but not at once, but during the period of one orbit of the Moon, so your example has no sense at all.

I am sorry, but your explanation is incomplete. You explained tidal locking but did not explain why it happens.
Tidal locking happens because the moon is a deformable body, and because of Earth's gravitational tidal force, it deforms to become an ellipsoid.
Tidal forces are the stretching forces due to the difference in gravitational force between two points. The region of the moon closer to Earth will experience greater gravitational force than the one further away. This distorts the moon from a sphere to an ellipsoid.
This slight bulge of the ellipsoid is closer to Earth, so it has more force of attraction; hence, it is forced to always point towards Earth. That is the main reason for tidal locking.
This deformation of the moon is crucial in understanding tidal locking because a perfectly rigid sphere cannot get tidally locked.
I have avoided the technical details of how deformation for the moon comes at an expanse of its rotational energy (or speed of revolution, depending on which has less period). This syncs the period of revolution with the period of rotation.
This is difficult for my brain to wrap my head around it?
The rotation of the earth is different from the moon's. Why wouldn't we notice this change as it revolves?
