The Big Bang

If the universe is expanding, what is it expanding it from?




Big Bang Theory - 1 theory
-approximately 14 billion years ago.
- space and time were actually created during the big bang.
- all matter and energy was found in one dense, pressurized, extremely hot point(a very very small point!)
- in an instant, the point expanded and began creating the universe
- the early universe expanded rapidly
- hubble's use of red/blue shifting gives some concrete evidence to support this theory
