Yay - back to re-creating the Big Bang. That should burn the Swine Flu off

Get ready for the Christians moving the goalposts to accommodate the Big Bang once they've proved it happened.

I think its only narrow minded Americans who deny the big bang. Generally Christians accept the big bang theory, as much as Physicists do at least, Particularly those Christian Neuclear Physicists that work at CERN.

Christianity merely requires a creator, which i would suggest is a prerequisite of creation.

God created Man

almost correct

actually, it was

Man that created God

I don't know where He lives, various different places according to his representatives

I can't see the LHC proving that the BB occured. Will do all sorts of fun stuff though!

And here is a handy website that allows you to check in realtime that everything is going OK, in case you're one of those who is concerned...

Woohoo - we can have another "end of the world" party

we did the last time they fired it up - ok, we just like a good excuse for a part, in fact any excuse for a party.

7 billion

Something that has always confused me is the size of the known universe - currently estimated at 156 billion l/y across, and the age of said universe - 13.7b years.

According to Einstein nothing travels faster than light (yes I know there's a get out when warping spacetime but....), yet it's expanded at nearly 12 times the speed of light.

There is a reason for that simon but i cant remember it now. Google it and you'll find an answer! One part was the speed of light being different in the early times, and also relativity between the two sides each leaving the centre at the speed of light. Theres more im sure!

As far as I can remember, it's to do with the fact that the expansion of the universe is not just stuff travelling outwards (at max the spped of light). Space itself is expanding making things more distant than their velocities would suggest. In other words even if all the 'stuff' wasn't moving at all, space itself would still be expanding and distances between the stuff would still be increasing. Something like that. Plus there's something called inflation in the current model - a sudden burst of rapid expansion early in the universe. This inflation and the normal expansion have no speed of light limit. And that's my understanding of how the universe can be much bigger than stuff moving outwards from a single point at the speed of light for the age of the universe suggests it should be. There are actual proper ways they know all this too, of course - i.e. it's not all 'just a theory' as Jon's Christian buddies might say .
