Switch-on nears for proton smasher
Updated on 08 September 2008
Scientists will this week "switch on" the most powerful particle accelerator ever built as they prepare for an epic journey back in time to the birth of the universe.
The £5 billion Large Hadron Collider (LHC) will smash protons - one of the building blocks of matter - into each other at energies up to seven times greater than any achieved before.
In the flashes from the collisions, scientists expect to reproduce conditions that existed during the first billionth of a second after the Big Bang at the dawn of creation.
