This theory states that the entire universe began as a small, hot, energy point that expanded over billions of years into the universe we see today. This theory is supported by:

  1. Cosmic background radiation left over from the big bang.
  2. Galaxies are still moving apart.
  3. If the big bang occurred the way scientists think it did, they predicted that there would be a certain amount of helium out in space. In 1995 a space shuttle mission measured that level of helium in space.
