The BBC reports:
Researchers working on the Large Hadron Collider (LHC) say they are delighted with the progress made since the machine restarted on Friday.
One official said the collider had done more in a few hours than it did in five days of operations last year.
The LHC is being used to smash together beams of protons in a bid to shed light on the nature of the Universe.
Housed in a 27km-long circular tunnel under the Franco-Swiss border, it is the world’s largest machine.
During the experiment, scientists will search for signs of the Higgs boson, a sub-atomic particle that is crucial to our current understanding of physics. Although it is predicted to exist, scientists have never found it.
