I can't help but notice that at the galactic scale, the journey of the sun is so short-lived.
If the galactic year is 230 million and the sun is roughly 5 billion year old, that means the sun is only at its 22nd orbit around the center of the galaxy.
Given that the sun has 5 billion more years before turning into a white a dwarf, its whole journey as shining star would last 44 galactic years... assuming the sun doesn't run into another star in the next 5 billion years.
Also, great episode and thank you for your hard work.
Just barely old enough to drink. Cheers, Sol!
Define short lived. How is the Sun's journey around the galaxy "short"? In distance? In time? It's neither, ultimately.
You are taking HUGE journeys through massive amounts of distance and time and feeling that it is not so massive simply bc the number 22 is "small". Once you zoom back in and realize that 22 times journey is bigger than our brains can even properly imagine, it doesn't seem small.
Don't forget, this is spacetime, not just space.
I find it even more impressive that the whole milkyway has only turned like 60 times or so since its existence. You wonder how it could even arrange itself within so few rotations.
since our sol is a G-type star, that time of living is a bit average. let's not forget other O/A/B stars have such a shorter time to live. some even 'die' long before our star finish a galactic year, maybe just some several millions of years. however there are other stars live longer than ours (M/K)
and there are hypothetical ways to 'improve' our star lifetime by 'extracting' a bit of our star's mass so it could burn out longer than 10 billion years. but this is another topic for another 'verse' =)))))
@@cowlinator How US-centric, the sun's been drinking for 6 (galactic) years in (galactic) Germany.
I can't believe how well done these videos are, and they are free. I'm so grateful.
I have seen an advertisiment for "QuitSure" app before this video started.
Free thanks to the support of generous donors.
I'm even more amazed by how they managed to avoid pitching Nebula subscriptions. Apparently, that can be done. The mind, 't boggles.
@@deusexaethera like the American Taxpayer... But hey, if they built roads as well as they do educational content, I might quit the Libertarian Party.
@@KCNusach : PBS gets about $25M a year from taxpayers -- a little less than a single F-15 fighter jet, not including maintenance.
I love the little “this is what I think” in the outro. That kind of thing just feels so refreshing to my brain after trying to understand all the science of space-time.
It's also nice like it's just his opinion and not part of the script
I have been enquiring how the Sun moves through the galaxy for a few years & couldn’t find much information about this. Delighted to have this so brilliantly explained. Your Knowledge is astounding and so inspiring. Thank-you for blowing my mind whilst providing such understandable teachings. ✨
Surely one of the pinnacles of wisdom and science is the ability to interpret and break-down complex information into everyday terms for those without years of study to appreciate and understand with a curiosity to know more. Great video.
Well put
If you ever want to know if someone truly knows more than surface level knowledge on any subject, ask them to explain it like you're 5. If they can't, they more than likely know very little.
@@LtShifty not always true. I can’t explain certain things in a way that anybody understands, and most of the time even confuse myself, but I can do it and even show somebody how to do it.
@@LtShifty Well I have known many experts/teachers who definitely did know the material very well but they seemed to refuse to explore new or better ways of breaking it down for their audience. They were very stuck in their one way of explaining or teaching the complex information, and if I couldn't immediately catch on with all the complexity and plethora of new terms and concepts then it was somehow my deficiency in their view. A very unfortunate and backwards attitude I've always thought. Some of the experts really put in the extra effort or are naturally gifted and can explain these things to the public and it's a breathe of fresh air to a curious mind to want to dig deeper into the subject.
@@bobbyt223 I hate to be the bearer of bad news 😂
I'll agree if communication isn't your strong suit then fair enough, trying to dumb something down can be difficult. But I still believe that in most cases, the inability to simplify a complex topic is a clear sign of a fundamental misunderstanding of core concepts.
Currently working through all the previous videos, Matt and the PBS team have made an invaluable resource
welcome aboard bud, i think my IQ has gone up 20 points the last 3 years lol

@@dan7291able Well, not sure about my IQ, but my depth of knowledge has expanded like the primordial universe.
@@dan7291able That’s not how iq works.
@@starling1226 lol it's a joke bud relax, you're on the wrong channel if you're "that" type of person
Love the debunking, without any unnecessary negative energies (semi amateur pun intended). Truly amazing channel, 100% outstanding stuff, 100% of the time. God bless
Bravo! This video not only clarifies misconceptions about Earth's motion but also sheds light on the broader context of galactic dynamics. The explanation of the Local Standard of Rest and its implications for studying dark matter was especially illuminating. It's incredible to contemplate the intricate interplay of forces shaping our cosmic journey. Excellent work!
As an old git who has had a life-long layman's interest in such subjects, it's still very enjoyable to learn more about such, even at a fundamental level that helps stitch together other things I've learned so that I get an even greater understanding/appreciation of the bigger picture.... and PBS serves up those juicy morsels with impressive regularity.
At 8:08, I suddenly had flashbacks to being a kid in the 80s and using Spirographs as a form of entertainment. (Ask your grandparents kids) And the 80s synth pop was helping!
Me too.
Same :D
I had flashbacks to something else.
I'm still watching and love how he can make complex scientific information easier for a layman to understand. Thank you
Depending on your frame of reference, we have never been in the same place for our entire lives. Even sitting here, relatively still, my body is moving at thousands of times the speed of sound.
The Delorian would have gone back to 1955, and popped up into the void of space.
And it's for sure true.
@@ExxInferis Yep. That's why time-only travel is at least impractical, you would always end up in the vacuum of space. Space-time travel would be a solution, if only we could figure out a way to determine the absolute starting and ending position of the trip. A small error, very small, infinitesimal compared to the distance traveled by Earth, let's say 100m, would shoot you in the air or deep underground. So, in my humble opinion, this consideration alone makes time travel impossible.
@@ExxInferis True! 😂
@@maxsignori316 Reminds me of Han Solo telling Luke Skywalker why calculations are needed to fly through hyperspace.
"Without precise calculations you could fly right through a star, or bounce too close to a supernova, and that would end your trip real quick."
I was literally trying to envision the path through the universe the other day and I just couldn't get past what it might look like based on just our galaxy, let alone everything else around us
I was trying to envision it as well but my chauvinistic, toxic male brain was not up to the task. I had to ask my mommy to explain it better. She tried her hardest, but I guess men aren't capable of understanding these advanced concepts.
@@mrquicky dude... go touch grass...
@@mrquicky ?
I'm afraid Matt maybe making a mistake by showing the galactic disk with us bounding up & down through it. They rest of the galaxy is also moving in such a way that they can nearly be nullified. So the the disk makes the motion with us; like we're a 50 lbs girl scout, with floaties, in a wave pool, circling the drain.
Quirks gonna quirk, I guess.. Remember that the main thing is to learn how to keep your main things the main thing.
What a fantastic teacher and researcher. I highly respect someone who corrects himself and answers key questions at the end. Thank you for this great content!
learned more than I thought I was going to
@@Elias_Halloran no you didnt
Every one who can go on google is a researcher. He he is Scientist who is also a researcher.
@@addy405 Anyone who can go into a library can be a researcher
Bahahaha. Fantastic at teaching a lie. Great
There's an error in the video at 4:30, since Jupiter and Saturn years are not 5 and 12 respectively, but around 11.9 and 29.5 respectively.
The 5 and 12 are actually about the distances from the sun expressed in AU, but not quite -- Saturn is more like 9.5 AU
He kind of has a brain fart there. But he was pretty good
@@millicentsmallpenny5837he mentions timescale and precession of the barycenter. I don’t think he meant distance to the sun. I think he merely mistook his facts and also seems to appreciate when his viewers catch his slip ups 🤭
Well explained! My mind has been exercised into a deep three dimensional paradigm, where it normally doesn’t go. Thank you for the ride! Brilliant! Just brilliant!
that last little bit, on what you actually think other life could be made out of and the "out there" being multiple universes away was kind of mind blowing. thank you for sharing your mind with us all, it is so wonderful to just think about things
Finally, an answer to satisfy the "but what if we just don't know about it" responses
Words cannot describe the excitement of seeing a new space time video being posted... its like the scholastic book fair for adults
For adults? I'm 17 it's same for me too
@DevilSingh You would understand his comment if you knew what a scholastic book fair is. If you know what it is, then all I have to say is "Whoooosh".
@@MJ-ig3fo I know brother. I'm in 12th currently. I've attended many scholastic fairs and even bought books. My school arranges these fairs once every year. If you know "Geronimo Stilton" is a story line I love.
@@MJ-ig3fo don't take my comment seriously. I just wanted to say I also feel same joy for space stuff as the one who commented that that's is. 👍🙃
It is hard for me to believe people still believe the lie about space. Open your mind and see the truth and stop believing the lies NASA IS PUSHING.
Just wanted to thank you for all the knowledge spread. I always struggle trying picture how we are able to get a reference point at all from our location.
Great video, really happy to see that at the end you also looked at the Galaxy traveling through the Universe itself. I was starting to worry that wouldn't be covered.
Our path through the universe is WILD yet what’s more wild is that we can understand this much about it! 😮
The least understandable aspect of the universe is that we can begin to understand the universe
Not my statement, but I also don't recall the person who first stated it close to that
I assume many lay people don't understand why we know so little about it in total that being everything past local group.
But I agree from my frame of reference.
The universe is just math -- lots and lots and lots of math.
@@deusexaethera Math is probably the most abstract thing humans can conceive of, so it's not surprising we'd take it to be a cogent candidate for the composition of the universe. The same can be said of the concept of 'information'. Unfortunately, ontology lies outside of epistemology, and so is reduced to an unfalsifiable personal metaphysics.
You think you "understand this much about" your 'wild path through the universe'?
Everything in the Universe is moving relative to each other; so there is really no so-called "path through the Universe". lol
It is more of a "path through" your overworked imagination. lol
This is my favorite channel on CZcams. Nowhere else can I find such complex information presented in such an elegant and understandable manner.
Have you tried Anton Petrov? IMHO him and PBS are THE top science and cosmology channels on CZcams without question.

@@desel8737 Ooh, yes! Absolutely! Can't believe I forgot them.
@@desel8737 their political videos are horrendous though.
You need to closely vet that channel
@@GalacticNovaOverlord I don't see what you mean. I just looked at the channel out of curiosity. Please give 2 or 3 examples.
I love you Matt O'Dowd. your work has always been a calming treat on the sea of internet videos. thanks. I read and listen often.
Wow that was an absolute brain stewer by the time I got to know how an individual body is moving through space. But absolutely mindblowing visuals coupled with a simple narration just helps me once again feel v.v.v.v.v.v.v.v smaalll. Thanks!
I can learn from this man because he does not have a shrill voice with eccentric personality while also being condescending. He does a great job. An excellent teacher. I greatly appreciate the absence of infantilization of the material and the viewers.
Just come out and say it. Whom are you criticizing? ; ) You're among friends.
Indeed, I'd like to know some of these names, too. Generally speaking, I don't really notice whether a voice is annoying or not. The only one that comes to mind is the narrator of Astrum. Can't recall his name off the top of my head.
Gibberish PAL, here time to wake up. Regarding Spheres in Space 🌍and Comets: The on screen CGI showing spherical ball🌝🌍⚽objects floating in "Space" is pure nonsense. Our Sun and Moon are local ionizing gas plasma luminaries, travelling within the Tropics. Earth is a fixed level Plane of existence made of fossilized, mineralized biology of mainly ancient Titanic Dragons🐉 some thousands of miles long, turned to stone (Limestone, and Granite) 🗻mountains.

The Void of space and level Earth was called the "Raqia" in ancient Hebrew (Latin-Firmament), and "the Expanse" is so massive we get Hyperbolic, and Interstellar (now) Comets. Due to Magnetic Force, when these massive transition metal (conductive) laden space fossils get near Earth's dipole, the Anode is discharging electrons into the "Comet" nucleus and taking protons from it. The Comet is now a hot cathode from a cold state (far away) and Sublimation-Phase Transition (from solid to a gaseous state) is causing it to discharge Carbonaceous Dust and microbes etc. by the hundreds of Tons an hour (example) as a Type2 Comet science.nasa.gov/science-news/science-at-nasa/2013/19apr_isonids above Earth.

The electrical Shar is likely an intentionally induced 👽Cosmic Cycle, which adds raw material (Proton Density, Radial Velocity etc.) to the outer magnetic field of the Toroidal Vortex EMF above the level Earth.

I see what you did there. And I agree.
PBS Space Time never started that way. It's come a long way, and matured into a very good educational channel.
This will be perfect for the next time my students ask me this question, thanks PBS!
Just phenomenal. Even when I am bored with everything else on yt I know I have pbs spacetime which I can binge watch. I rewatch a lot of good videos such as this to enjoy the experience. Would definitely support you in the near future.
Regarding frames of reference: if you want to travel in time, you have to know where the earth is going to be when you reach your destination. You also need to know which direction it’s moving. So far we have motion on the solar system, motion through the galaxy, and our galaxy’s motion, plus, I believe, a local galactic cluster motion. Still, to be safe, if I were traveling backwards in time, I would do it in a spaceship in case I didn’t end up where I expected.
04:24 Did Matt just say that the "orbital periods of Jupiter and Saturn were 5 and 12 earth years, respectively???" He must've meant 12 and 29 years and we just misheard him ;) Also, why is the solar system in this video sometimes depicted from above the north pole (planets circling counter-clockwise) and other times from below the south pole (clockwise planetary orbits). Is that to prove that he's not a polar chauvinist? I'm sure being from Australia has something to do with this..
@@onlytruefalcon 5AU is Jupiter's distance but 12 yrs is its orbital period. Saturn's distance is 9.5AU :(
Stellar episode, as always!
Often I see a PBSST-title and think "meh, I'll watch it, but I probably already know this" and everytime it'll teach me a whole lot more than I anticipated. I _really_ should know better by now 😄
I too was thinking about this a couple days ago. Thank you very much. That definitely helps me keep a mental image of our path through our universe. Now if I can just figure out if North is truly the top of our planet or if it's something that northern hemisphere folk came up with. Are we actually spinning in the different perspective? Do all stars spin in the same direction? Our Galaxy has a horizontal plane; do all star systems rotate accordingly to that? Does the universe have a horizontal plane.
And of course no one expects you to memorize all the chemical formulas. Someone on your team should be responsible for fact checking that though. This is a science show. Should get the science correct. It's a little embarrassing and discrediting when you don't. Stop pouting, cheer up. Mistakes happen. No worries, we all still eagerly await the next knowledge you share with us. Just be amazed that some viewers are knowledgeable enough to notice things like that. I have a better grasp of the philosophical meaning to all past events and the meaning of life vs technical stuff like that. Lol
Galactic episode?
True, there is universal agreement that this episode is stellar.
I see what you did there...
Finally, and thank you! An explanation of the 'current' orientation/ecliptic of the plane of the solar system in relation to the movement through the galactic plane. 👍
This has been very informative on how we move throughout the universe and our own solar system😊
This was one of my favorite episodes so far. I love galactic astrophysics.

The video somehow not only presents amazing mathematical and scientific information about our path through the universe, but also simultaneously captures the incalculable marvel and delicate balance of cosmological motion.
One of my favorites I've ever seen on this channel. Outstanding.
yeah! what they said!
It's so complex, that the only answer will probably, most likely to be, that we are in fact. Inside a. Simulation.
@@830jps I agree.
and when we use computers to simulate reality, how do we build the environment?
Do we start with building the simulation on a spinning ball orbiting other celestial bodies?
I don’t think we do. If we are in a simulation inside a computer, it’s probably designed the same way we use computers to simulate reality.
How can a Time Lapse photo of the North Star possibly help your argument?
Essa é a coisa mais legal que já vi sobre como a nossa galáxia funciona!
This is one of the very few channels related to science that are actually worth watching for, most of them are just pure rubbish. Very good content, keep up the good work! The quality is far above anything available elsewhere, explanations and animations are both very well made, random guesses are not stated as facts - which is rare. This can truly call scientific.
As always, a topic that I’d previously given very limited thought to is filled with complexity, beauty, and for those asking the right questions, implications for the testing of much deeper questions and ideas of physics. Many thanks for this great content! 👍👍
These frames of reference remind me of the map projections regarding depictions of the Earth itself, that none can depict all of the information except for a globe but then you can't see the whole map at the same time. There's no single best frame of reference for all cases, as you said, in a way analogous to the map projections.
This is the 1st clip that I didn't get completely lost about half way through. I was able to actually follow this one beginning to end.
Thanks Matt and all PBS team to visualize this for us. Very good explained!
Hey Matt, you and the team have inspired me for years and I *finally* went ahead and got Brilliant with your code. I'm really enjoying the lessons and I feel like I'm that one step closer to a deeper understanding of what has always excited me more than anything else: space, physics, and awesome ideas. It's been really nourishing, just like your videos, so I wanted to give you a heartfelt THANK YOU ❤️ You guys are the best are your job. That isn't even conjecture.
That "extinction 60 million years ago" and the thought of whats to come is really blowing my mind
Very impressed with this video. I have always been interested in astronomy and physics. It was things like this that drove me to enter those professions. Thank you for feeding my insatiable curiosity about the universe and the wonders that we discove
This is an incredibly good video. Thank you Matt (and team!!) for putting in all that effort to bring this to us. I wish we had you guys around when I was in school.
Hey, PBS Space time. I rarely comment, but I realised I have watched your videos religiously for some 10 years. Keep up the good work.
Here is something I think you should consider. I don't know if you have done anything like this, or experienced it, but years ago I put a vinyl record on a fan motor spindle. It would work more safely with a piece of canvas or shower curtain. If you perturb the edge or anywhere while at speed, the perturbation will remain, even after your finger is removed. I believe this relates to the ball chain from the jar experiment and probably has a name already. Anyway, the dent or flexture remains, not only in dimension of size and shape, but fixed relative to directions in space and from the spindle. Even with the considerable centrifugal force trying to remove it. I am one hundred percent certain that this effect occurs in galaxies as well. It may have a relationship to what is called dark matter, in that this effect may be partially responsible for the observed inconsistencies.
This is one of the most interesting videos I have ever seen. Thank you!!
Follow-up questions: In which direction does our CMB-relative velocity point? How much of that velocity is due to The Great Attractor and/or the Shapely cluster (what TGA is moving towards)? If we account for the motions due to Andromeda, TGA, and Shapley, do these add up to the CMB-relative velocity? If not... what accounts for the rest of it?
And what direction is the CMB-relative velocity regarding Earth's orbit around Sun and what direction regarding Sun's orbit around the galactic centre?
Is the Great Attractor moving?
Finally, a well produced video which tells the whole story of astronomical movements and the differing frames of reference that can be chosen, and why they are all equally valid. Vsauce started the madness six years ago and never corrected his error. This sets it straight.
Omg, we are learning so much more about science every day that it gets hard to keep up with what's current. Nice video great information lots to learn
This is impressive what we have worked out. Very interesting and I need to see this more than once
One of your absolute best videos. A simple hypothesis is simply explained but with a mind-boggling conclusion. Well done guys, I'm looking forward to your next epic mini movie.
Matt, you and your team are incredible. Thank you!
Yes, Bravo!
This is by far the best thing i have watched on youtube in the last few years.
Great presentation. I’d trust you to make the big decisions for future space research. The length of time it would take me to catch up to speed with the knowledge you possess, is longer than years our earth has left to exist. Carry on sir 🍻👍
I enjoy these videos so much. The combination of raw knowledge, humor, and great graphics never fails to entertain as much as educate. Thanks for another awesome experience. =)
So basically teleportation is the worst superpower. Got it.
Mind is a blank. Hope it doesn't get worse.
I just LOVE your content! You have so much knowledge and present it easily and understandable. Thank you for your efforts!
Thank you for explaining this! I've asked myself this question over the years and knew that we where moving in a myriad of directions.
Mega like this video. It helped me answering how Earth move through space! I now need to find the video explaining the sun trajectories we see thoughout a year from earth.
Thank you for this wonderful video. I have often wondered about this particular subject.
Thanks, a really great illustration of how complex things get when one takes all factors into account. All depends on how far outside the solar system you want to go I guess!
Mind blowing just mind blowing. How fortunate we are for this wonderful internet , awesome CZcams that brings us amazing people like Matt to tell us the wonders of the Universe!

The Void of space and level Earth was called the "Raqia" in ancient Hebrew (Latin-Firmament), and "the Expanse" is so massive we get Hyperbolic, and Interstellar (now) Comets. Due to Magnetic Force, when these massive transition metal (conductive) laden space fossils get near Earth's dipole, the Anode is discharging electrons into the "Comet" nucleus and taking protons from it. The Comet is now a hot cathode from a cold state (far away) and Sublimation-Phase Transition (from solid to a gaseous state) is causing it to discharge Carbonaceous Dust and microbes etc. by the hundreds of Tons an hour (example) as a Type2 Comet science.nasa.gov/science-news/science-at-nasa/2013/19apr_isonids above Earth. The 3600 yrs. ago Thera Eruption marked last cycle of energetic Comets, and it was called the "Shar" in ancient Sumerian, the "Completion of the Circuit". The electrical Shar is likely an intentionally induced 👽Cosmic Cycle, which adds raw material (Proton Density, Radial Velocity etc.) to the outer magnetic field of the Toroidal Vortex EMF above the level Earth. The "Solar Wind" is the measured strength of the EMF Torus (AKA magneto/heliopause) without it the harmful ionizing UVC radiation from the Void would make life on Earth impossible. The last Passover 3600 years ago (Minoan erupt
Indeed we are among the fortunate. Let us rejoice and celebrate this banquet of knowledge. Felicitations 🎉
Thank you for doing this video, those other videos totally ignore point of reference. Well done.
First time subscriber 💚Inspires me to go back to school just to talk with other nerds again! 🤓 very cool of you to involve fans in quality checking your videos! Much respect.
You are the highlight to my day. Please keep up the good work. Love the existential feeling I get watching these videos..
I love memorizing chemical structures. So much easier than words or numbers or equations to me. They all have different personalities like cartoon characters and tell a story as one's eyes drift around them.
The idea that non-carbon based life is possible but likely in a different universe is fascinating. Thank you.
Pretty much every spacetime video is great, but this one is among the best
Thank you,Mathew O'Dowd and the great staff of Space Time for making such wonderful programs. I would be nowhere without your influence on me. I am truly grateful for the hard work that you do.🙋♂️
Same! I’ve decided to become an Earth Scientist because of Matt (and his videos have helped me greatly during exams). Gonna go into astronomy after UG
@@rainbowbutterflyfan you'd be better off learning asstrology rather than wasting your life on asstronomy which is not even a science.
Its tragic watching people self-immolate on the SCIENTISM sacrificial altar.
How can a Time Lapse photo of the North Star possibly help your argument?
Quite literally went from "this seems like a boring episode" to "this has been one of the most eye opening episodes yet!"
Great job
the most complicated things often come from the most mundane
No such thing as a boring episode of Space Time!
Already seemed interesting to me. I was hooked by the title.
I'm imagining all of the flat earthers who have used that corkscrew helix animation as an argument for their ridiculous theories, watching this video and having their minds absolutely blown 🤯
Absolutely loved the graphics. No one does as good of a job explaining as spacetime
This is one of my favorite topics to bring up when I am trying to get people interested in astronomy.
This was a really good one! Keep up the great work, this is consistently the highest quality content on youtube!
Thoroughly enjoyed this video. I was able to follow despite not being a scientist. Thank you
You need a sidekick to do those "story for another time" :) This is the very best science channel.
And you were so kind to Nick Lucid.
I really enjoyed the video. I have been trying for some time, to picture the trajectory of Earth's travel, taking all of the factors under account.
I enjoyed watching this episode. It follows on the heels of a long discussion I had with my friend about the subject of proper motion and frames of reference. Seems I’ll be dining on crow after I show him this episode. Thanks for the illuminating show.
Amazingly clear and interesting, well done !
I've been listening to your hypnosis videos for years!! Finally a face to go with the voice 😊
I'm just glad not to be dizzy all the time.
I've always wondered what affects the furthest stars on the end of the galactic plane have on the particles that are super far away from those stars, which are still on the tail end of the galaxy.
Awesome video
The reason I think it makes sense to think that the solar system one makes sense is because we generally do that: we anchor movement to the next bigger thing. So when seeing the moon orbit, the earth is still. When seeing the motion of the earth, the sun is still. So when we talk about the "movement" of the solar system, to me it makes sense to make it in terms of the center of the galaxy which means the solar system is corkscrewing around orbiting the super massive black hole at the center.
I believe that's maybe "just in conversation" but that's kinda what I want to get out of a cool gif.
I get we don't choose our reference frame, but feels that we all know what it means when we say, "how does the solar system move" that we mean relative to the center of the galaxy.
Terrific discussion of astronomical motion! It makes me almost believe that I can understand it! :) Thank you!
Yet another excellent explainer from PBS Spacetime! As if there are any other kind from this channel. 😄 They're as reliable as Anton (though far from as prolific), with the occasional wit of Sabine. An excellent combination, I must say!
❤️❤️
Good stuff and of course we include the frame of reference, that we can all directly experience in reality from our perspective as we walk out the front door of our home every day, no matter what location we reside in: that we are standing on a stationary topographical plane with the sun, moon and stars rotating above.
When you are on a plane with no turbulence can you tell how fast you are moving? Of course not. We only feel acceleration or deceleration. Believing we live on a flat earth is simply inexcusable for any adult with a shred of intelligence.
Fantastic job explaining this - i was always curious but confused
Excellent content and quality, as usual. Thank you!
riding in the back of a windowless moving truck at my last job, moving at a constant speed, you couldn't tell if you were going forward or backward. I can only assume it wasn't sideways, but I can't prove that.
This is so much better than those PBS videos that move at maniac speed. Thank you.
Sounds like your explaining 1000 year cycles and longer for the earth.
Great video.
Just wow٫ this is the best space channel on CZcams٫ period.
Give Anton Petrov a try.
He speaks to us …
Not down at us.
Saw this blow up on reddit and was also shared by some family members on Whatsapp. Thank you so much for clearing up the misinformation so nicely!!
First video I have watched, one of the best too fantastic content.
Excellent content and quality, as usual. Thank you!. Excellent content and quality, as usual. Thank you!.
The visuals were extremely helpful thank you
Here is the full clip : czcams.com/video/bceIOLb7HIw/video.html
Incredible episode. Great work gang!
Such a masterpiece explanation of motion of earth
Great episode. ST never disappoints.
