I thought scientists concluded that The Big Bang never happened.
Nope.
That line gets repeated a lot on the internet but as far as I know the Big Bang Theory (the theory itself, not the TV show) is as solid in astronomy as the standard model is in particle physics.
I've said it often: one of the great tragedies of the Gobal Warming Hoax is that it tends to make all science seem like a hoax. It is a great tragedy.
Global Warming is a hoax.
The Big Bang Theory (the theory itself, not the TV show) is not a hoax and currently explains more about astronomy than any light-years-distant second contender.
