[00:00.000]Scientists at the world's largest
[00:02.230]particle accelerator have successfully collided
[00:04.980]beams of protons at the highest energy levels ever seen.
[00:08.140]There was cheering in the control room at CERN,
[00:10.990]the European nuclear research center in Switzerland
[00:13.680]as one of the biggest and most complicated
[00:15.820]scientific experiments got fully underway.
[00:18.520]The experiment is seen as a major breakthrough
[00:21.520]in efforts to understand
[00:22.900]the fundamental nature of the universe.
[00:24.470]Doctor Martin White is a research fellow at CERN.
[00:27.940]\"One of the great mysteries
[00:29.460]of the universe is that most of the mass
[00:31.250]in the universe is some kind of dark matter.
[00:33.740]It's some kind of particle
[00:35.260]that doesn't match anything we've seen before.
[00:36.740]And if you look into space,
[00:38.060]you can see this
[00:38.970]because you can see its gravitational pull.
[00:40.300]So wonder thing is that we hope to get,
[00:42.090]recent or earlier,
[00:43.160]an effective scene in the next two years
