You don't understand.
The protons go around the 27km loop 11000 times a second, however today they just fired one around in one direction, stopped it. Then fired one round in the other direction. Just to check it all works in both directions and stuff.
At full speed when they collide the protons will be doing 99.99% of the speed of light.



 i have set them straight though. Clarkey1984, thats me mate!
 he can at least sleep well at night knowing he set me straight on you tube today!
