The idea that something collided with the Earth and created the Moon is an unscientific, absurd idea. There is a zero percent chance that a collision as described could result in the Moon maintaining an almost perfect orbit around the Earth, and the Earth maintaining a near perfect orbit around the Sun.
- s1artibartfast 3y agoSo all the planets popped into existence with their current Mass and Orbits? Of course not. Mass is summed as is momentum
- purpleblue 3y agoEverything was formed by the spinning of gas clouds and consolidating into planets and such. That's why the planets haven't fallen into the Sun after 14 billion years.
- andrewflnr 3y agoWhich is why nothing has ever collided in the history of the solar system, because they all started on perfectly parallel orbits? Is that about right?
- purpleblue 3y agoNothing large enough to cause a planet to split into two ever collided. Yes.
- andrewflnr 3y agoReally. Interesting. What do you think was the cutoff size for objects that can collide? Can you justify it quantitatively, given your "zero percent chance" line earlier?
- s1artibartfast 3y agoindeed, and how is that proof that the moon didn't come from a collision with the earth?
- wolfendin 3y ago> There is a zero percent chance that a collision as described could result in the Moon maintaining an almost perfect orbit around the Earth, and the Earth maintaining a near perfect orbit around the Sun. I’d love to see the math you did to come to that conclusion. Do you have it in a paper somewhere?
