Has seen a collision. http://news.bbc.co.uk/1/hi/sci/tech/8593780.stm
Now, i know i'm as thick as two short planks, but i find this really interesting, was watching that Prof. Brian Cox on Wossys show the other night explaining it a bit in simpletons terms and got into it, he said that 27k stretch of tunnels they've created under Geneva, that they are pushing particles through, WILL see results shortly, and so it has.
Brian seems quite excited on twitter
, and his show is worth a watch on iplayer Wonders of the Solar System
Wish i understood it a bit more like, but i'm trying.
