      For many reasons – see here for more details

      http://www.talkorigins.org/faqs/astronomy/bigbang.html

      The fact that the universe is homogenous (stars, planets etc are minute perturbations) in all directions and that the deviations from this are tiny (a few parts in a 100,000). This is now being measured very precisely by the Planck probe and previous to that by WMAP and before the COBE – the radiation from the Big Bang is all around – a small % of the interference fuzz on an analog TV are the electromagnetic waves left over from the Big Bang

      The fact that we’re so spread out in space makes me think that everything came from one massive exposion. Trouble is, no one was around back then to see it so there are other theories. What do you believe?

      If you leave the telly on and you see that snowstorm effect that’s electromagnetic waves from the Big Bang
