Title: Physics question
Post by: WhoTookMyUsername on February 13, 2011, 01:43:40 pm

Not sure how the universe expansion thingo works.
Is everything just getting bigger (proportionally)
or are new thngs being created?

If everything is just getting bigger, where did existing planets etc. come from? where they all condensed in the big bang,

Not sure about the creating things, but everything is moving further away. Like stars and galaxies.

I was going to answer your question but the arrogance conveyed in your forum signature is repulsive.

Space is getting bigger, matter isn't. All mass was in the singularity prior to the big bang. Hence constant mass all growing further away from each other.

There are many theories of the universe, but atm it is expanding.
