When I was 10, I told my father that we only see one side of the moon from Earth. He told me that I was wrong. I told him that I learned this in school. He grounded me for talking back at him and told me to tell my teacher that she was wrong. Loving relationship obviously, but he was not the only person in my life to have such strong attachments to the idea that we see all sides of the moon from Earth. This phenomenon has always perplexed me. All one has to do is care enough to pay the slightest attention to our closest stellar neighbor to see that our view of its surface never changes, other than the shadow across its surface. It all goes to show that, not enough people look up. I guess they are afraid of getting bird poo in the eye. My wife was in her late 20s when she pointed out a strange object in the day sky. It was the moon. I often wonder how these enormous details are missed for entire lifetimes. I wonder what I, myself am ignorant too. Fortunately for life lessons, I do not allow cognitive dissonance to get in the way of learning something new every day. Thank you for the video from a decade in the future.

It still doesntmake sense to me because it is not rotating as it revolves.

for gravity, the force is constant as its always interacting with the body, so the acceleration, therefore is 10m/s² downward

Gravity !!!!???? You Mean the same thing that NASA cannot prove, and Einstein said there's NO WAY to prove it !!!! WoW 😮 are you indoctrinated !!!!

I agree with the above statement 😊. The acceleration ore deceleration will be zero at the point of changing direction. There is the forge of gravity that will welkom it back on earth..but the rock has no engine ore propulsion..that could do it ..change it..with maximum acceleration. 😮

Acceleration needs 2 points to calculate because it's a comparison between two points. The definition of acceleration is a change in speed.

Perfect teaching . 👍🙏

That explains me and my first wife.

Or moon just like sun is stationary yet both revolving round us

Probably explains why The Far Side of the Moon has so many more craters from objects in space striking it. It's always got The Far Side facing out

finally I FOUND IT!! JESUS BLESSED!! THANKS FOR UPLOADING THIS VIDEO!! GOD BLESS YOU!!🎉

Je ne comprends pas

I see sp many clip but this is the only one makes me understood why we dont see the far side of the moon.

It gets bigger. All of the part will scale up. If you doubled the size of the part, the hole would get 2x bigger. Thermal expansion does not increase size to that extent, but it does uniformly scale all features in a similar manner. You can also imagine the atoms that make the edge of the hole getting further from each other, expanding the hole.

gets bigger probably

Stays the same? Where can I find an answer

0:43 , 1 year is the metric being used. (this "time" around the sun of earth's orbit" ?? ) More and more this seems like a ridiculous metric from a "talking monkey" (homosapien) perspective. what is therefore 1 year on Venus, Mercury, Mars, Saturn etc.... ? How does that translate into a light year ? Is "time" even real? If "year" is used in a completely different capacity to describe "distance" here, then please explain with timestamp in your video, thanks.

a?

Decrease

Great!!!!! ☺️

Without watching I'm going with they aren't big enough.

We are but a mere spec in this universe

I could be wrong, but my intuition says: The water between the voids will feel weaker gravity towards the voids, therefore relatively stronger gravity in the directions pointed away from the voids, therefore the water in the gap between the voids will flow outwards from the gap, causing the gap to contract, making the voids appear to be drawn closer together. Though water would "evaporate" into the voids, filling them with water, if the water fills the entire universe, then the limits of the rate at which densities of water can equalize over the vast distances will result in the areas that started empty remaining less densely filled with water for a long time. I think the areas being lower density regions rather than completely empty regions won’t change the result of the thought experiment from the video. So the end result, according to my intuition, is a merged void (actually a pocket of colder, less dense water gradually equalizing with the rest of the universe as a bubble of reduced temperature/density water propagating outwards).

In the universe, there's actually no space, dude! Only quantum fields creating geometry :-P

the uh- the uh- the holes would get filled in with water (no he pretends it's difficult so uh-) The empty holes would set up diving schools? And uh submarines would be spaceships?!

Less! It's the radius and mass below you which is relevant in the formula.

someone posted a solution assuming its dark matter but if we assume its just vacuum/air then the water will fill the spaces, the empty spaces created after the water moved will be filled by other water, and eventually the empty spaces will travel to the edge or, if there isn't one, stretch out and become thinner and thinner over time

Tricky, alright. We know empty space in our universe expands due to the some 68.3 % dark energy in it. This makes it expand by some 70 km/second per Megaparsec. If these specific blobs are just empty space it would mean dark energy were 100 %. Thereby these blobs would expand towards each other, join and push all the water away from it. The gravity of the water would aid this expansion, accordingly to the points of gravity he demonstrates I don't know; haven't looked for the answer yet ...

the empty space would be rapidly filled with water

That is actually something to think about🤔 I don't know what it is though😅

ok, someone do the work and go and find out the answer and post it as a comment below...

Does that mean that in 6,500 years it will be Springfall in the entire year for everyone?

Thanks

a bullet have no momentum it only slow down and drop out at sonic x3 velecity

This is awesome.

I love this. My curiosity is accelerating.

Sink to the bottom, because increase in pressure will reduce the volume of air in the balloon

Wabit😂

Easy for scuba divers. Surely sink!

Ah, I know! The right answer is "I do not care":)

Stay?

The surface area of the ballon decreases due to the extra pressure on the balloon so the weight of the of water the balloon is displacing is less now than the weight so the it will sink.

Thank you it so much

DensityBalloon1=m/V1 DensityBallon2=m/V2 D1/D2=V2/V1. Pressure1=ph1, Pressure2=ph2 Where h=depth P1/P2=h1/h2 Since P2>P1 then V1>V2 therefore D2>D1 then balloon should sink.

Sink, the force for the float is equal to how much the weight of how much space the balloon takes from the water. As the depth of water increases the pressure will increase and make the balloon smaller. Hence the floating force will decrease

I wonder if the pressure that the water from above to maintain level puts it on top the balloon. Then the weight would pull it down.

Sink….
