The Large Hadron Collider finally restarted again, with beams colliding at 7 TeV, an energy three and a half times faster than ever before.
It should hopefully usher a potential change in how we see physics, the nature of the cosmos, and how we came to be.
Scientists opened up the champagne after it started producing the record-breaking collisions, and for 18 to 24 months will be able to examine the results coming from the particle accelerator.
However it wasn’t without problems - it took three attempts before it started to run successfully.
The CERN Twitter feed reported at the point where it finally worked, and suitably the writer’s excitement made it sound like Captain Picard was doing something a bit mental with his photon torpedoes.
10.40 am - “Beams look really good this time, Preparing for energy ramp!”
10.54 am - “Ramping up now!”
11.11 am - “Half of today’s energy at the LHC: 1.75 TeV! All lights are green!”
11.22 am - “Physicists hold their breath in the control room of the LHC.”
11.30 am - “3 TeV at the LHC. Almost 3.5 Tev...”
11.41 am - “The ramp is successfully completed! Beams are now accelerated to 3.5 TeV, the highest energy! Preparing for collisions now!!
11.49 am - “Operators are stabilizing the beams... yes, we’ll attempt to collide them soon!”
11.58 am - 12.01 am - “Final sequence for collapsing is starting! Collapsed, now stabilizing the beams. Experiment have seen collisions!!!!!!!!!!!”
12.01am - “First time in the history!!!!!!!!!!!! World record!!!!!!!!”
12.03 am - “Nature does it all the time with cosmic rays (and with higher energy) but this is the first time this is done in Laboratory!!”
12.23 am - “Now we have stable colliding beams-first time ever at this energy!”
Another latest tweet showing that data is already being collected successfully: “Experiments have already recorded thousands of events! We had more than 1 hour of stable and colliding beams.”
And the latest: "Experiments have half million events! More than three hours of stable and colliding beams. WOW!"
