Big bang theory

• Observations of red shift support the theory that the universe began as a very small area that was extremely hot and dense that then exploded outwards and has been expanding ever since.

• If this were correct then it suggests that there should be high energy radiation produced during the Big Bang that would be present everywhere in the universe.

• We have observed cosmic microwave background radiation all through the universe that has expanded to a microwave wavelength.
