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.
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.
@@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.
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.
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.
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.
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.
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?
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 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
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.
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!
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.
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.
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.
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
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!! 🤔😆
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.
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.
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.
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
Well I suppose it's easier to just fall back on God or Aliens when science gets difficult rather than do some actual work. Fortunately for you there are people who do work these things out which is why you can use a magic glowing brick to watch these videos rather than living in a cave and worshiping the twinkly god's in the sky.
@@garethwynn01 I am not religious, so fighting the argument for god and thinking you won, wont work here...im not religious at all. in fact, quite the opposite.

@@chaztitan6457 I said God OR Aliens. As an engineer I would hope you'd understand how to interpret a logical OR. Being unable to explain something and then asserting something even less plausible is a clear logical fallacy.
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.
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
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
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.
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.

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
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.
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 ??
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?
@@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.
Im not trying to say anything with this ... But its so ... lets say ... amazing ... that our planet ... "a Thing" which can not think, take decisions and actions ... somehow have the Perfect Parameters for life to exist. When we say perfect parameters, we realy mean perfect ... any small errors can drastically change it to a planet like the other ones ... where life is not possible. We, humans with all the knowledge we get / have, still cant get perfect parameters on anything we do and always still have errors, small or even big ones. But our planet ... not. Plus ... to me, looks like every type of Live Form from the Planet, the Nature, the Animals, the Humans, etc, again ... are like perfectly "built" as "Entities" and function around the keywords ... If / When / And / Or / Then ... We, to get where we are, we needed to practically copy what "Nature Evolution" did by itself, alone, so perfectly and precise and We still Can Not Do It perfectly, still having so many errors. To me ... looks like our Planet and every type of Live Form from the Planet are actually the result of a Higher Mind / Minds who meticulously planned and crate all this. Like an example... If anyone is trying to explain that A Plant, not an animal or the human who have a brain which can help ... just A Plant ... "was thinking", planning then "took the perfect decisions" and "action" to "adapt, live and reproduce" ... and if we take this explanations as correct, then ... wow. And that without going in to details of the discussion about all the "Perfect Parameters" around this example which will make all this even harder to believe. In the beginning i said that i dont want to say anything about this ... But if we just stay a little and think, we will easily see the obvious ... We Were Created by "Someone" / "Someones" Was God? God is who "we know" He is? Or was / is Someone Else? I really hope that God is Who we know He is ... Even if there are more and more Discovered Signs which "say" that God is someone else... But again... lets truly hope that is not the case. But its so obvios that in reality, "The Perfect Parameters Evolution" can be just an amazing Fantasy Story and / or Movie ... but not the true.
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?
Bro, I can't understand the Tidel lock between the earth and moon. I watched many videos regarding that but I can't believe that. Please explain this. My exact doubt is moon is also rotating itself, so somewhere we can see its front side and somewhere we can see its back side. Then how can be it tidel locked ?
Hi i had this same doubt but i am cleared now. I will try to explain it. Watch without rotation and with rotation once again. Imagine the orbit of the moon around the earth as a clock, so it will be easier to understand. Without rotation the moon shows its other sides, Understood yes. But now with rotation the moon constantly creates an opposite side to that. So now it feels like it is not rotating. Bcz its cancelling the side change created which will be created without rotation. Try this with a two objects which has unique sides. You will figure it
"I watched many videos regarding that but I can't believe that. " It is totally irrelevant what you, or me, or anyone else, believes. "My exact doubt is moon is also rotating itself, so somewhere we can see its front side and somewhere we can see its back side." We can see back side of the Moon only from place in space that is behind the Moon. But, since the Moon rotates around itself at the same speed as it is orbit around us, it turns always the same side toward our direction.
@Robert M Simpson Jr Yeah sure... ... and, when the sky is white, water above evaporated, and when the sky is read, it's fire burning above... Glass dome.... ROTFL
Lets try this. You are a dancer and you have a dance partner. Let's say the dance floor looks exactly like the face of a clock, that is, it has 12:00 at the top, 3:00 at the right, 6:00 at the bottom, and 9:00 at the left of the clock. You are standing in the center of the clock. Your partner is standing just under the 12:00. (1) You (in the center) are facing your partner eye-to-eye who is standing at 12:00. Thus you are looking north at her. Your partner is facing you, thus she is facing south inward to the clock. (2) Your partner is a good dancer and she can twirl, or do a 360, or spin without falling. Said another way, she can "rotate" flawlessly. (3) Let's watch her rotate. Nothing else moves for now, just her. Facing you she turns to her left and faces the east. This is just a 1/4 turn or 90 degrees. Now from the east she makes another 1/4 turn to her left, and is facing north completing a half rotation. From the north she makes another 1/4 turn to her left and now she is facing west. She then makes a final 1/4 turn to her left and is now facing south again and facing you. She has just made a complete rotation. Please note that. (4) In the step above she did all of her rotation standing at 12:00. She is your moon. Her whole life REVOLVES around you! Now we will see what happens when she rotates AND revolves and let's see if she will still face you or not. (5) As in step (1) you are facing north--12:00-- looking at her, and she is facing south looking at you in the center. She rotates to her left and faces east. BUT, this time she also revolves, she does not stay in a fixed position at the 12:00! If her rotation speed and revolving speed ARE THE SAME then she will be at the 9:00 position on the clock. Why? As she makes a 1/4 turn to face east, she as moved 90 degrees. We also make a 1/4 revolution to the left about the clock face or 90 degrees also because they BOTH (rotation and revolution) move at the same rate. Note she is now facing east as she should. She is facing you in the center. The earth rotates too so if you were to match her speed you would see her face-face again. However the earth's rotation is faster so YOU may not see her face-to-face but she WILL be facing somebody on earth. She is looking inward toward the earth (clock). We see her face and only her face at this position. We will just stick to the clock and have you match her speed for illustration purposes. (6) From the east she makes another 1/4 turn to her left such that she is facing north, or the 12:00 position. However, as she is rotating left she is ALSO moving left (revolving) to the 6:00 position of the clock at the same time during the process again. She goes from east to north which is 90 degrees, so if she also move 90 degrees on the clock at the same time, she goes left from 9:00 to 6:00. She is facing north from 6:00, thus she is still facing the clock looking upward at you. (7) From facing north she rotates left 1/4 turn or 90 degrees such that she is facing west. If she rotates 90 degrees, she also must also revolve left 90 degrees, thus on the clock she goes from 6:00 to 3:00. From the 3:00 position facing west she is still facing or looking inward toward you and the clock. (8) From facing west she rotates left 1/4 turn or 90 degrees such that she is facing south. Again. She's come full circle. She also must revolve left 90 degrees, thus on the clock she moves from 3:00 back to 12:00. As when we first started she is looking inward towards the clock and facing you. She has made a full rotation and a full revolution and all the while she was facing inward. Her face was ALWAYS toward the clock, we never saw her back! Her rotation may seem subtle, but she DID fully rotate. We are usually seeing rotations and things moving at different speeds and so we wonder "how is it possible for something to turn completely around without us seeing all sides of it?" Well if you rotate 1 degree and revolve 1 degree at the same speed you see the same orientation. If you're turning left as you're moving left you see the same face. Look at it this way, how can you walk for two steps and not get anywhere? Walk one step forward and one step backwards. One move can compensate or counter the other thus resulting in no gain or loss of position. Speaking of the moon's movement how about Michael Jackson's moonwalking? He could walk walk and go nowhere at the same time! Cool! Just thought about it, here's an easy set up. a) Hold your phone with the face facing you. b) From the phone's perspective turn the face to the left and hold. c) Now move the phone to your left side. It is still facing you. d) Now turn the phone face left again and hold. e) Now move the phone left of your position, it will be behind your head (it's okay to turn with it, the earth does). The face of the phone is still facing you even if you don't turn to see it. f) Now turn the phone face left again and hold. g) Now move the phone left of your position. It is still facing you. h) Now turn the phone face left again and hold. i) Now move the phone left of your position. It is still facing you. I'm in a swivel chair so I can rotate myself quiet easily. We have come full circle rotating (turning the phone face left) and revolving (moving the entire phone to your left from the prior position) the phone with its face still facing me. You may not think the phone has rotated, but it has completed a full return. And you never saw the back of it! No more mystery. Try using or playing with some props as above, it is easier to see what's happening than trying strictly "the common sense" approach. I didn't get it either until I started using objects to help my non physics mind see. Again, one thing is certain re the earth/moon movements; if the moon rotation and revolution are at the same speed seeing one side of the moon is the ONLY result you could possibly have. Hope this help and wasn't a waste of your time.
@@Konvicct so what's the speed of the moon's rotation, not the revolution? If the earth rotates at roughly 1,000 miles/hr, what about the moon? Earth's rotation gives us the obvious 12 hr contrasting dark and bright skies..dark when we are not facing the sun. Bright when we are facing the sun. Thus, proved the erth is rotating while revolving around the sun. Why can't we get same outcome of the same concept with the moon?
He said that this phenomen is very common for all planets that have a moon. Jupiter has plenty moons i will go to Stellarium program and set my location to Jupiter, then i will see what i would see from jupiter.
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.
@@RajinderYadav 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 the moon is turning anti clockwise on its axis as well as revolving anti-clockwise around the earth surely at certain points the gravitational pull of the sun would be greater than that of the earth? Is TIDAL LOCKING not just a THEORY? Could you maybe have painted one side of the earth black as you have done with the moon and create an animation (which includes the sun ) to explain Tidal Locking and Eclipses and also GRAVITATIONAL LENSING? I think that by showing the interconnectedness it might make this theory more comprehensible.
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 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.
Same.. I still don't understand
Same here 😞

For moon rotation and revolution is same
It’s path around the earth is not a perfect circle tho. It’s elliptical, so wouldn’t that mean it’s rotation is not constant. Speed up slow down?
I just couldnt see it in my head without the provided visual. Thanks. I didnt realize how slow the moon rotated on its axis.
A small correction : time required for one full rotation =time required for one full revolution.

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.
I saw that too. Big mistake
I have to stop watching the video before my brain get exploded due to the confusion.
Notice in that first graphic both say "ROTATION". The one should say "revolution"
No actually it's correct. It says the time of rotation of moon is exactly same as time of earth's rotation, i.e, 24 hrs it's called synchronising
I agree, Jeff. It is an unfortunate mistake.
@@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.
@@KCLBrunel yep you are right I'm bit confused😅
@@KCLBrunel yaa..... You're absolutely correct.
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.

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
@@Abrar1950 i don't think you understand what "its own axis" means.
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.

Thank you for this lunar explanation, especially the clarification of the moon's rotation and revolution.
I'm still so confused. The animation looked to me like we are still seeing the other side.
I tried to explain all this on another post here. It is long. Look at my response to poster Arun Poomalai. It may help.
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.

Nice explanation
Removing the Earth is how I finally got it!!! Thank you! Omg my brain
Wow. Everything is so crystal clear due to this cartoon. How could I ever doubt this story? Science knows everything, bah bah bah.
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?
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.
Thank you for this wonderful and amazing information... Selenophile here..
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

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.

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.

The moons orbital plane is differ than that of the earth around 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.

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
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.

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
When viewing the moon from the same exact location, how has it completely rotated 180° and appears upside down in the sky?
This is difficult for my brain to wrap my head around it?
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.
Yes. That's why the earth always shows the same side to the sun. Because science.
At 0:45 it should be = Time Required for one full revolution (right side)
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 ??

We, to get where we are, we needed to practically copy what "Nature Evolution" did by itself, alone, so perfectly and precise and We still Can Not Do It perfectly, still having so many errors.
To me ...
looks like our Planet and every type of Live Form from the Planet are actually the result of a Higher Mind / Minds who meticulously planned and crate all this.
Like an example...
If anyone is trying to explain that A Plant, not an animal or the human who have a brain which can help ... just A Plant ... "was thinking", planning then "took the perfect decisions" and "action" to "adapt, live and reproduce" ... and if we take this explanations as correct, then ... wow.
And that without going in to details of the discussion about all the "Perfect Parameters" around this example which will make all this even harder to believe.
In the beginning i said that i dont want to say anything about this ...
But if we just stay a little and think, we will easily see the obvious ...
We Were Created by "Someone" / "Someones"
Was God?
God is who "we know" He is?
Or was / is Someone Else?
I really hope that God is Who we know He is ...
Even if there are more and more Discovered Signs which "say" that God is someone else...
But again... lets truly hope that is not the case.
But its so obvios that in reality, "The Perfect Parameters Evolution" can be just an amazing Fantasy Story and / or Movie ... but not the true.

My exact doubt is moon is also rotating itself, so somewhere we can see its front side and somewhere we can see its back side.
Then how can be it tidel locked ?
Hi i had this same doubt but i am cleared now. I will try to explain it. Watch without rotation and with rotation once again. Imagine the orbit of the moon around the earth as a clock, so it will be easier to understand. Without rotation the moon shows its other sides, Understood yes. But now with rotation the moon constantly creates an opposite side to that. So now it feels like it is not rotating. Bcz its cancelling the side change created which will be created without rotation. Try this with a two objects which has unique sides. You will figure it
"I watched many videos regarding that but I can't believe that. "
It is totally irrelevant what you, or me, or anyone else, believes.
"My exact doubt is moon is also rotating itself, so somewhere we can see its front side and somewhere we can see its back side."
We can see back side of the Moon only from place in space that is behind the Moon. But, since the Moon rotates around itself at the same speed as it is orbit around us, it turns always the same side toward our direction.

ROTFL
Lets try this. You are a dancer and you have a dance partner. Let's say the dance floor looks exactly like the face of a clock, that is, it has 12:00 at the top, 3:00 at the right, 6:00 at the bottom, and 9:00 at the left of the clock. You are standing in the center of the clock. Your partner is standing just under the 12:00.
(1) You (in the center) are facing your partner eye-to-eye who is standing at 12:00. Thus you are looking north at her. Your partner is facing you, thus she is facing south inward to the clock.
(2) Your partner is a good dancer and she can twirl, or do a 360, or spin without falling. Said another way, she can "rotate" flawlessly.
(3) Let's watch her rotate. Nothing else moves for now, just her. Facing you she turns to her left and faces the east. This is just a 1/4 turn or 90 degrees. Now from the east she makes another 1/4 turn to her left, and is facing north completing a half rotation. From the north she makes another 1/4 turn to her left and now she is facing west. She then makes a final 1/4 turn to her left and is now facing south again and facing you. She has just made a complete rotation. Please note that.
(4) In the step above she did all of her rotation standing at 12:00. She is your moon. Her whole life REVOLVES around you! Now we will see what happens when she rotates AND revolves and let's see if she will still face you or not.
(5) As in step (1) you are facing north--12:00-- looking at her, and she is facing south looking at you in the center. She rotates to her left and faces east. BUT, this time she also revolves, she does not stay in a fixed position at the 12:00! If her rotation speed and revolving speed ARE THE SAME then she will be at the 9:00 position on the clock. Why? As she makes a 1/4 turn to face east, she as moved 90 degrees. We also make a 1/4 revolution to the left about the clock face or 90 degrees also because they BOTH (rotation and revolution) move at the same rate. Note she is now facing east as she should. She is facing you in the center. The earth rotates too so if you were to match her speed you would see her face-face again. However the earth's rotation is faster so YOU may not see her face-to-face but she WILL be facing somebody on earth. She is looking inward toward the earth (clock). We see her face and only her face at this position. We will just stick to the clock and have you match her speed for illustration purposes.
(6) From the east she makes another 1/4 turn to her left such that she is facing north, or the 12:00 position. However, as she is rotating left she is ALSO moving left (revolving) to the 6:00 position of the clock at the same time during the process again. She goes from east to north which is 90 degrees, so if she also move 90 degrees on the clock at the same time, she goes left from 9:00 to 6:00. She is facing north from 6:00, thus she is still facing the clock looking upward at you.
(7) From facing north she rotates left 1/4 turn or 90 degrees such that she is facing west. If she rotates 90 degrees, she also must also revolve left 90 degrees, thus on the clock she goes from 6:00 to 3:00. From the 3:00 position facing west she is still facing or looking inward toward you and the clock.
(8) From facing west she rotates left 1/4 turn or 90 degrees such that she is facing south. Again. She's come full circle. She also must revolve left 90 degrees, thus on the clock she moves from 3:00 back to 12:00. As when we first started she is looking inward towards the clock and facing you.
She has made a full rotation and a full revolution and all the while she was facing inward. Her face was ALWAYS toward the clock, we never saw her back! Her rotation may seem subtle, but she DID fully rotate. We are usually seeing rotations and things moving at different speeds and so we wonder "how is it possible for something to turn completely around without us seeing all sides of it?" Well if you rotate 1 degree and revolve 1 degree at the same speed you see the same orientation. If you're turning left as you're moving left you see the same face. Look at it this way, how can you walk for two steps and not get anywhere? Walk one step forward and one step backwards. One move can compensate or counter the other thus resulting in no gain or loss of position. Speaking of the moon's movement how about Michael Jackson's moonwalking? He could walk walk and go nowhere at the same time! Cool!
Just thought about it, here's an easy set up.
a) Hold your phone with the face facing you.
b) From the phone's perspective turn the face to the left and hold.
c) Now move the phone to your left side. It is still facing you.
d) Now turn the phone face left again and hold.
e) Now move the phone left of your position, it will be behind your head (it's okay to turn with it, the earth does). The face of the phone is still facing you even if you don't turn to see it.
f) Now turn the phone face left again and hold.
g) Now move the phone left of your position. It is still facing you.
h) Now turn the phone face left again and hold.
i) Now move the phone left of your position. It is still facing you.
I'm in a swivel chair so I can rotate myself quiet easily. We have come full circle rotating (turning the phone face left) and revolving (moving the entire phone to your left from the prior position) the phone with its face still facing me. You may not think the phone has rotated, but it has completed a full return. And you never saw the back of it! No more mystery. Try using or playing with some props as above, it is easier to see what's happening than trying strictly "the common sense" approach. I didn't get it either until I started using objects to help my non physics mind see. Again, one thing is certain re the earth/moon movements; if the moon rotation and revolution are at the same speed seeing one side of the moon is the ONLY result you could possibly have. Hope this help and wasn't a waste of your time.
@@Konvicct so what's the speed of the moon's rotation, not the revolution? If the earth rotates at roughly 1,000 miles/hr, what about the moon? Earth's rotation gives us the obvious 12 hr contrasting dark and bright skies..dark when we are not facing the sun. Bright when we are facing the sun. Thus, proved the erth is rotating while revolving around the sun. Why can't we get same outcome of the same concept with the moon?
He said that this phenomen is very common for all planets that have a moon. Jupiter has plenty moons i will go to Stellarium program and set my location to Jupiter, then i will see what i would see from jupiter.
The rotation of the earth is different from the moon's. Why wouldn't we notice this change as it revolves?
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.
@@willoughbykrenzteinburg have you proved this to yourself? but it's fact! i mean science.
@@RajinderYadav 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.
@@RajinderYadav Why you waste your time with brainwashed ignorants who believe everything they are told.....
Thnx
how other moons behave?
If the moon is turning anti clockwise on its axis as well as revolving anti-clockwise around the earth surely at certain points the gravitational pull of the sun would be greater than that of the earth? Is TIDAL LOCKING not just a THEORY? Could you maybe have painted one side of the earth black as you have done with the moon and create an animation (which includes the sun ) to explain Tidal Locking and Eclipses and also GRAVITATIONAL LENSING? I think that by showing the interconnectedness it might make this theory more comprehensible.
The sun is very massive but also wet far away.
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.
Will you please tell me the name of the background music at the end of the video at 3:14
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.
@@max5250 Curved space is a competing theory only. There are others that disagree with it.
