What are these scientists up to? Just re-creating the Big Bang so we can all disappear in a black hole of our own making, that's all! Madness. It's fine, of course, they're not really expecting that to happen. Well, there's only a very small chance...y'know, not enough to worry about.
I'm telling you this is a bad idea. Circumspection would be a very, very good thing here. Scientists aren't circumspect - they make bombs, and drugs that have devastating side effects, and stuff that causes pollution, and it'll all turn round and bite us on the bum one day.
We don't advance through science, we just create a different set of problems. Wipe out one devastating disease and you get another in its place. Like the police trying to stay one step ahead of the criminals, we try to get the better of nature - and we do for a brief moment - but then she hits us with something else because she's cleverer than us.
It's not knowledge we need, it's kindness.
Anyway, this experiment. Today one of the critics is quoted as saying that if it has the effect they fear then nothing will happen for four years and then stuff will start going catastrophically awry. So, let's see, four years - that'll be 2012. The very year that the ancient civilisations always said the world would end.
