the moon from the earth

[GiZMO]

how did the moon get separated from earth exaclty?

[The Ataris]

there are a couple possibilities
1. the earth captured the moon during the formative stages of the solar system
2. it was formed from the debris after a planet the size of mars collided with the earth
3 i forget what else but there probably is some other theory

I'd say we'll never know...

What does this have to do with Evangelion?

[GuGuEaTeR]

as in Evangelion sense, a meteorite or sumthing struck Earth and caused First Impact. this created moon, and also creating Pacific ocean. that's far as i can guess :p

This is how it relates to Evangelion. In episode 7 (I think) they show a document from some history thing about the history of the world after the second impact. Here is a screen cap of the part of it about the first impact

yes in nge the moon does originate from the earth, though science in real life would tend to place the moon as being older than the earth, and that the earth probably came from the moon...

Well, I think thats the latest theory, and it actually uses impact to explain the existance of moon :D

Using powerful computers, scientists with the Southwest Research Institute (SwRI) in Boulder, Colorado and the University of California, Santa Cruz (UCSC), believe they can now prove how our Moon came into being.

Researchers Robin Canup and Erik Asphaug started with the basic idea that a large, Mars-sized object slammed into a young Earth not long after the solar system was formed. (This idea was first proposed in the 1970's, but lack of time travel has prevented any actual eye-witness accounts to prove such an event.)

Using a computer modeling process called smooth particle hydrodynamics, researchers took the impactor and the Earth and divided them into 20,000 small, discrete pieces. They were then able to run computer simulations of various impact events and watch how each tiny piece would react to the resulting explosive forces.

After running a simulation where the Mars-sized impactor slammed into the Earth at an oblique angle, the resulting debris coalesced into a moon of just the right size, composition, distance and rotation. In other words, the product of their simulated impact seemed to match our Moon.

This model improves on previous impact scenerios that required "a disturbingly narrow range of conditions" to produce the Moon we have today, according to planetary scientist David Stevenson with the California Institute of Technology.

One earlier scenario required not one but two large impactors to hit the Earth at different times, one to create the moon, the other to alter the Earth's spin to its current rate. Another scenario called for a giant impact to occur on a half-formed Earth. While the second model would have produced a proper-sized moon, the Earth would still need to grow in size to its current mass. As the Earth collected more mass, so too would the newly-formed moon. Thus the final product of the second model would be a properly-sized Earth with a much larger Moon.

"The model we propose is the least restrictive impact scenario, since it involves only a single impact and requires little or no modification of the Earth-Moon system after the Moon forming event," said Dr. Canup, Assistant Director of the SwRI Space Studies Department in Boulder.

USCS Professor Erik Asphaug adds, "Our model requires a smaller impactor than previous models, making it more statistically probable that the Earth should have a Moon as large as ours."

While the oblique impact of a Mars-sized object with a young Earth seems to answer many of the questions about the Moon's formation, we will probably never know for sure how our Moon came into being. Without eye witness accounts, the best scientists can do is piece together existing evidence. Even though 12 men have walked on the Moon's surface and gathered samples of its rocky surface, there is still a tremendous amount of things we don't know about our nearest neighbor. All we can do is keep studying, collecting data, and keep trying to fit all of the pieces together. The latest research certainly appears to be a step in the right direction.

I watch something about the creation of the moon in the Discovery channel so time back. I forgot on what theory they decided to adapt. Either it was a piece ripped off from the Earth due to some castastrophical event or it was synchronously formed along with the Earth.
