<How could a planet collapse under it's own gravity? What would generate that much gravity? Your idea needs a lot of support to get that ball rolling.
Any astronomical object above a certain size is spherical because of its own gravity. If you were to chop something the size of Earth in half with a cosmic Ginsu knife and separate the two halves, each one would behave as though they were made of a large glob of liquid, despite the seeming solidity of the planet to the layman. Each half would collapse separately into a sphere (about 6,350 miles in diameter each), generating in the process one hell of a lot of heat.
I would suggest using history as a guide instead pulling silly ideas like that out of your head.
That's where I pull all my ideas. From where do you pull yours? I have a couple of guesses.
Good thing you don't do anything important otherwise I'd begin to worry. Take a science class and learn something.
I used to teach an astronomy class, but that's probably neither here nor there. And if I had something important to do all day, I wouldn't be able to hang here. Lucky, huh?

How do you think it gets to BE a goddam planet??
