The origin of the moon

The theory of the moon's formation that has proven most fruitful is the so-called Giant Impact Theory. In this theory, an early protoplanet dubbed Theia shared Earth's orbit at the beginning of the solar system. It then collided with the Earth to make the moon. This video shows a computer simulation of this event, made at the University of Colorado.

I would love to have seen that in person from a nice vantage point. If all of that happened in a day, what a wonderful day of entertainment that would be. Set up some lawn chairs and a barbecue on your spaceship's patio, have a few beers, watch some planets explode. What more could you want?

I cringed when the lady explaining the model kept saying "we believe"... When a scientist speaks to the public, they need to be a little more careful with their words, as a lot of people will point to that phrasing as "proof" that science is little more than another religion.

And yay, on the 3rd day, the Lord created the moon.

...at about 3:15pm... by shooting a 22 cal. worldlet through it, but Mrs. God was standing on the other side, and the God Police came and after about 3 billion years, God was finally set free so he could finish us.

Intelligent Design works quite well. kthxbye.

Um, no. Let the ignorant believe what they want; scientists shouldn't have to carefully choose their words for the sake of idiots.

So a planetoid strikes a perfect glancing blow on early Earth, which rips the planetoid apart but doesn't blow protoearth into smithereens.

The result of the collision is that Earth receives an addition of iron to its core, which in turn generates a stronger magnetic field, thus keeping the solar wind from stripping off our atmosphere, a la Mars.

The collision also imparts a slight axial wobble to Earth, allowing for an uneven heating and cooling of the planet, generating weather systems in our atmosphere and supplying a near-constant temperature that's perfectly suited for complex amino acids to form chains.

Finally, the remains of the collision hang in our sky, providing us with a fairly workable asteroid shield, tides -- and at the right moment in time, -perfectly- block the sun, allowing a group of astronomers to confirm the predictions of a Swiss patent clerk and thus understand the fundamental nature of the universe.

Your god is an awsome god? My science makes your god look like a toddler.
