Watch How the Moon Was Formed
itwbennett writes "A pair of NASA videos released today show the moon as you've never seen it before. In one video, you get an up-close tour of the moon's craters, thanks to video and images from the Lunar Reconnaissance Orbiter. In the other, you can watch an animation of the moon's creation and evolution."
How did they narrow down the timescale of the events to be so specific without any samples?
This does not correspond at all to how my pastor says the earth, the moon, the sun, and everything else was created. Why should I believe what NASA has to say?

Who says it's hollow, and was towed here by aliens.
Didn't the moon impact the earth at one point? Isn't that why it's fairly lopsided?
-SaNo
Strange that they would animate the meteoroid impacts with sound.
Last I check, there wasn't any sound in the near perfect vacuum of space on and around the moon.
I've read lots about what happens to the earth when the move leaves orbit. but what happens to the moon? does it fly into the sun? towards jupiter? or become a planet of its own?
On the formation of the moon video, the time frame starts at "-4.5 billion years ago".
"4.5 billion years ago" or "-4.5 billion years" makes sense (the former making more sense, but the latter is still acceptable), but what exactly is "-4.5 billion years ago"?
Oh, what, you gonna tell me the moon evolved from apes?
that doesn't show how the moon was formed. isn't it supposed to be the result of 2 separate impacts?
When the meteroids impacted, they would have caused a broad spectrum of light. That includes light at very low frequencies.
A few years back, we watched an intense meteor shower. As the meteors became visibly 'fuzzy' and then 'snapped' out of view, we HEARD corresponding sounds. This seemed impossible, but turned out to be real (they weren't delayed by speed of sound). The cause was low frequency light, which was transduced by fine elements around us -- like our hair, and dry grasses.
So an observer with a full head of hair would have 'heard' sounds of the meteor impacts, if he was in a quiet environment.
When he was finished he left it behind.
It is not "How the moon was formed", it is "Why the moon looks like it does". Still a very cool video.
I can't help but wonder... why am I watching a NASA video where the crater's falling on the moon makes sound in a vacuum?
I know it's artistic license and all, but aren't videos like this reserved for nerds, who actually care about things like accuracy?

I thought it was common knowledge the moon was formed in Wisconson.
Based on recent articles in the Physics Today, the moon is almost entirely made of Earth Mantle. Therefore, the viewpoint of a georeactor megavolcano probably is more likely.
Based on recent articles in Science News, it seems that in the formation of Kimberlite rock, there is a reaction which can send the magma into orbit, basically with carbon dioxide being the rocket fuel.
Referencing back to a Slashdot article not too long ago, the main structure of the moon is from two smaller moons colliding in a fairly slow collision.
Based on the new kimberlites found in a huge ring of 950-mi radius all around the Hudson, and the age of the Hudson rock [ the margin of error in rock dating, plus the fact that georeactors will throw off the Uranium isotope counts but perhaps not the Pb/Pb counts, allow for the probability], I'd say that the Hudson is one likely origin of the moon.
*But* that doesn't mean I don't think a much smaller asteroid triggered it. Based on the probability that georeactors will create enough vapor pressure to keep themselves from getting dense enough to go critical, it would take a large, sudden, horizontal force on a uranium-laden calcium berg in the mantle, to force it critical. Once it went critical, shock waves in the mantle could trigger another georeactor on the opposite side of the earth.
My guess, based on all that? 2.1 billion years ago, a relatively small asteroid [that is, not mars-sized] impacted near the south pole at a shallow angle, plowing the submantle south of Tierra Del Fuego, and throwing shocked glass all around South Africa, Antarctica, and Australia. You can see the plowed area in Google Maps, from Del Fuego to the South Sandwich Islands. It triggered a georeactor that exists under the South Sandwich Islands, and at the time was under the Vredefort Crater. The georeactor blew, making the volcanic crater. On the other side of the globe, near where Iceland is today, was another georeactor, with what is now the Hudson Bay above it. That georeactor also blew, creating the bay, shattering the crust all around it, and causing Kimberlate / Lamproite blasts through the shattered crust.
At that point, you had a huge amount of matter orbiting the earth at relatively slow speeds. Some of it fell back, but a lot of it formed into two moons, which at some point later, merged in a relatively slow collision.
I can't throw a probability on the scenario, but I tend to think [based on the articles I have read] that that scenario is more probable than any other that has been proposed.

This much more informative video by the Smashing Pumpkins clearly shows that the moon looks like either cheese or some type of cookie. Furthermore it is populated with ugly jumping guys covered with craters that are easily defeated with a parasol or umbrella.

moon? It never does get old, does it?

Moon watch YOU being formed!

That's a must see - really well done.
So the moon hasn't change significantly in a billion years? Interesting.
