Answer 2

I'm afraid chase_123 is a little confused,
a theory is an UN-PROVEN Idea and THEOREM is something we know for a fact to be true. (ex) String theory and Darwinian theory are not proven therefore they are theory's where as Copernican theory (earth revolving around the sun and so on) is a proven fact therefor it is a Theorem my personally fav is string theory but I'm going to give you one of mine,
In my opinion IF the Big Bang happened, the amount of energy and speed it was released would create mass, it fits into E=MC2 energy is = to mass at the speed of light squared so it would make sense that the energy when it slowed down turned into mass and created planets and stars (stars would just be the mass with residual energy in it) and planets would be mass without any energy left, and with all the mass having gravity over time solar systems would be formed.
P.S.
this is just a thought I don't know if its a published theory or not it's just based on one thought leading to another and another, this line thinking can explain alot of thing's but it probably creates impossibilities somewhere but who knows

Answer 3

String theory, Evolution theory, Euclidean theory, evolution theory, Big bang theory (even though they've all been mostly proven.

Answer 4

william above does not understand what a theory is!

If a theory is proven then it becomes a fact.
The Big Bang and evolution are theories.
So is Creation.

Neither can be proved by operational science since neiher was observed and neither can be trested or repeated.

Answer 5

confusing situation. browse in google or bing. that will will help!

Answer 6

Chas_chas_123 is misinformed. I blame his parents.
