The Secret of the Dark Side of the Moon

Earth's gravity is so strong we only see one side of the orbiting moon. Modern exploration to the mysterious dark side revealed dramatic surprises and revised theories about the moon's formation.

They used old foren texts and hypothies also carveing and religeon. Also lazers and sonar and xrays to measure with calculus.

Why does a science channel assume "Impact creators" not very scientific.

I’ve seen pictures of the “front “ side of the moon, and I’ve seen pictures of the “back” side of the moon. The full disk. Since we have pictures of the “back” side, I know that it’s possible to have pictures of all sides. Can someone please direct me to the pictures of the “top” side, the “bottom” side, the “left’ and “right” sides. When I see them, I’ll recognize the areas of the front side, which we see all the time, right next to areas we never see. thank you.

The moon is a construct of unbelievable technology that is far superior than anything we can imagine. We have been deceived by our governments and our ancient ancestors left behind clues for us. Why do you think we haven’t gone back to the moon? Why is it that the photo’s of the “Moon” are censored out or in low quality? We sure have the technology. I’m no expert but if you take the time to do your research and hear the “stories” or “theories”, they all share a common factor. Something or someone is holding back and controlling our perceptions. But why???Wake up Humans!

Good theory and all but what about the fact that the moon is essentially perfectly round? Wouldn't it be funky shaped if the dark side had another moon morph into it?

And how do you know its 30 miles thicker on the dark side when you've never been there???

If that’s so, then how come we don’t see one half of the moon heavy crusted side if the former smaller chasing sibling moon had slowly merged-impact our bigger current moon? Hmm...unless the former smaller moon sibling was in a slightly higher orbit? This hypothesis they produced is ignoramus and looks “half baked and half heavy crusted” burnt to me, people! Purrrleeeezzzzz...go join the flat earth and never moon landed theorists bunch with this one-cell amoeba 🧠 dumb idea hypotheLUDICROUSis!

The only explaination why the far side of the moon is full of craters is because it catches all the impacts of asteroids towards earth, since it never faces us.

Gravity pulls the lava this way, and the suns reflection off earth makes the moon slightly warmer so the lava has a weaker barrier for the lava.
Jyotsna Gokhale (12 days ago)
It isn't "bizzare" 2:36 - it's gravity of Earth affecting Moon, just as the other way effect causes tides in oceans on Earth, and more. Lovely 3:00 - 4:00.

Ask students (incoming or outgoing) of MIT, if they can solve this easy question of astrophysics, which I asked on a french astronomy forum: 1) Considering a particular situation of the Moon, show that its maximum speed in a reference linked to the Earth, is greater than 6000 km / h! 2) Subsidiary question (very difficult) Could you determine the minimum speed of the Moon relative to the Earth? P.S: the speeds found on Wikipedia, for example, are completely wrong: only the average speed of the Moon relative to the Earth is accurate, and is worth about 3683.6 km / h. That the students reassure themselves: nobody "wished" to give the answers on the site in question (lol). Greetings from Paris. professor essef.

What kind of idiot will believe in such rubbish theory? here is my theory which looks better than theirs: We all know moon is part of our life, Moon act as a shield for earth, somehow it takes bullet for us long time ago and maybe even till this day, all those erosion you see is due to the impact of the meteors, and without the moon probably all those meteors would hit the earth and the life wouldn't be as same as today for us, without moon earth wouldn't be the same and probably life wouldn't be the same either, tide of the ocean and the gravity change all are related to the moon, so yeah my theory is moon protect us from the meteors and all that are sign for the meteor impacts.

How about that the moon on this side is protected from most meteorietes by our earth and the moon's far side is not protected and and get more hits by meteorietes that is why it is so ruff maybe this is a better theory

It's very possible that the cosmos has been around for a very long time. Millions of years ? Yes. It's possible God created almost everything and left if for millions of years, then put humans here at a later time. Normally we hear only two sides of the "where did we come from" answer. How about part of both is correct and part of both is wrong ?

Why would gravity keep the moon from spinning on its axis?
max5250 (14 days ago)
Who said gravity is keeping the Moon from spinning on its axis? The Moon is still spinning on it's axis, but it's spinning is synchronized with revolving around Earth.

Prince of all Negros (20 days ago)
If you feel a balloon with water since gravity is pulling down on it the bottom half is going to be thicker than the top half so shouldn't it makes sense that the Earth is pulling on the moon so the side that's facing us it's obviously going to be thicker then the other side because gravity is pulling everything towards this side? Maybe I need to work for NASA
skenky lump (20 days ago)
the moon is a see through mother foc***s, you can't see the dark side because there isn't any.
max5250 (14 days ago)
Saermed Haque (21 days ago)
There is no difference in crust thickness. What i think is that the earth gravity had such a strong pull on the moons near side even that long ago that it made the moons lava spillage to come through the near side. Also the moon took a lot for the earth. Impacts craters on the far side.. image a moon smaller than its size.. forget about the natural disasters that would come with it for a second. Half of the asteroids would miss the and impact the earth making development for life much more difficult. My theory.🤔

All the people on here denouncing science because this story may not be correct and because sometimes ideas and stories in science change have it completely ass backward. Science is amazing because when it gets the story wrong (as is sometimes the case - let’s face it, you get stuff wrong too, it’s a human thing and scientists are humans, sort of) science admits when it’s wrong and updates it’s theories according to the latest information. Of course science can never tell us everything. Of course science isn’t always right. If those two facts bother you then they are an impossible standard that you’ve imposed on science. You are born a baby with no knowledge. You will die with more knowledge than you started. Throughout your life you make observations, come up with ideas to explain what you see, tested your ideas, and refined your beliefs and ideas based on forthcoming evidence so that your ideas closely match reality. Nobody wants their perception of reality to starkly contrast with actual reality. That is to say, you want the description of the world in your head to be accurate, correct? Yeah so do science and scientists. It’s sad that all the information we learn over our lives is lost when we die. If only there was a way to record what we’ve learned and pass it on. Oh shit wait, we do that already, and when we pass on the information we learn about the physical world around us we call it SCIENCE!!!!!

0:39 ... "Although the moon rotates..." That should be finished with ... "Around the Earth and not on it's axis." And who are the people in this spewing speculative nonsense using no references to back up what they are saying? They are not identified. Horrible video.
max5250 (14 days ago)
So, you think Moon is not spinning on its' axis?! How come we can only see one side of it?

The explanation about the moon having a thicker crust on one side was because of another that merged over time in orbit but then why is it on the far/dark side but not on the side where it merged in the first place?

Oh my God this video killing me it is impossible for two objects in space too mush together, unless it is2 holes
David Skotarczak (1 month ago)
It's thicker on that side because of the pull of the gravitational force on the Moon from the Earth.it has to do with gravity, in some spots on earth the crust is thinner what makes the Moon any different.

Mary C (1 month ago)
Takes a licking and keeps on ticking! Seriously, were it not for the moon, look at the hits we would take. BTW, common sense says, over time, all those astoroid "hits" deposited a lot, adding to the top layer and making it thicker!
