From The Daily Mail:
Experts around the world are eagerly awaiting the switch on of the world's biggest scientific experiment, and none more so than Professor Stephen Hawking.
The £5billion Large Hadron Collider aims to recreate the conditions moments after the Big Bang that created the universe.
It could offer Professor Hawking his best chance so far of winning a Nobel prize if it confirms his theory that black holes give off radiation.
He told the BBC: 'If the LHC were to produce little black holes, I don't think there's any doubt I would get a Nobel prize, if they showed the properties I predict.
'However, I think the probability that the LHC has enough energy to create black holes, is less than 1 per cent, so I'm not holding my breath.'
The British physicist put forward his idea in the 1970s but it proved controversial because many scientists believed nothing could escape the gravitational pull of a black hole.
Although Hawking's theory has become accepted by the profession is remains unproven. Nobel prizes in physics are awarded only when there is experimental evidence for a new phenomenon.
The Large Hadron Collider (LHC) at Cern may produce microscopic black holes that could evaporate in a flash of Hawking radiation.

I hope the experiments go well and we do get lots of information about how the universe formed.

Dr. Hawking is a well respected thinker, but that does not mean he is correct.
Some physicists who re-examined Hawking Radiation have determined that micro black holes might not evaporate. Their papers conclude:
"black holes do not radiate"[1]
"the effect [Hawking Radiation] does not exist."[2]
"infinitely delayed Hawking radiation" [3]
If recent papers are correct, and the Large Hadron Collider creates slow moving micro black holes, then Earth's lifespan might be greatly reduced.
