ATLAS Scientists catch glimpse of the Primordial Universe

26 November 2010

After less than three weeks of colliding lead ions at the highest energies ever achieved, scientists at the LHC laboratory in Geneva, Switzerland, already have brought new insight into the universe as it existed immediately after the Big Bang. Temperatures at the collision point reached trillions of degrees, about the temperature that the lead nuclei would literally melt into a “soup” of its basic building blocks. Indeed, scientists of the ATLAS collaboration are the first ever to observe direct evidence of “jets” of particles as they pass through this hot, primordial soup.  Detector technology developed in Canada was critical to this success. The ATLAS paper was accepted by the prestigious journal Phy
