Today's test won't reveal any scientific insight, but in the coming months the two beams of particles will eventually be smashed together, at 99.99% the speed of light in absolute vacuum at near absolute zero, and analyzed by four detectors; LCHb, ALICE, CMS and ATLAS. This infamous video produced by CERN's Kate McAlpine explains the science behind the LHC in a fun way, so resist the urge to fall down laughing and watch it through once and you'll get the gist of how the experiment works.
