THE BIG BANG THEORY

Olivia & Chaney

EVIDENCE

  • Hubble's law is named after Edwin Hubble. This law states that the universe was once compacted and that the universe keeps expanding
  • It is stating that a galaxy is moving proportionate to its size. Since it says that it means that one day a long time ago it had to have started all together.
  • The Big Bang Theory states that the universe was once very hot and scientists have found Cosmic Microwave Background (CMB) radiation to prove this right
  • The amount of hydrogen and helium in the atmosphere corresponds with the Big Bang Theory
  • The Big Bang theory suggests that the galaxy was initially EXTREMLY HOT. We should be able to find evidence of this and we did. It was found in 1965 by Arno Penzias and Robert Wilson. The evidence that was found by those two wise men was Cosmic Microwave Background radiation.
