theories regarding the universe and the solar sytem.?

Question

what are the theories regarding the universe and solar system??? :)

Answer 1

I just answered a similar question, so I'll give you the same answer... The best theory is called "the nebular hypothesis".

The nebular hypothesis is a theory about how solar systems are formed. It says that a giant cloud of gas/dust particles (which resulted from the death of a previous star) condensed into itself. As material packed into the center of the cloud the whole thing started spinning, which flattened the cloud into a disk. The center of the cloud (where the most material ended up) becomes a star, and the outer parts of the cloud eventually formed planets, asteroids, commets, etc...

Here's a couple links for more information since this is such a brief answer...

Otherwise, there's always the good old answer of "God did it!"

Answer 2

Condensation of gases from galactic explosions.
