LHC back in action

Posted by:


Tonight scientists at CERN are rebooting the LHC (Large Hadron Collider) in an attempt to recreate conditions fractions of a second after the Big Bang by crashing opposing proton beams, traveling at nearly the speed of light, into one another. Shortly after the LHC’s debut last September, a manufacturing glitch in wiring led to a liquid helium explosion that left the surrounding equipment damaged and ice-coated. The LHC faced another (albeit more humorous) setback earlier this month when a bird dropped a piece of baguette into the machine, causing a short circuit.

Now that repairs are completed, scientists hope the LHC will offer insight into several puzzling theories such as dark matter and the Higgs boson, a particle which gives other particles mass.
