ALICE will study collisions of heavy nuclei, like Pb.
WHY?
The collisions between Lead nuclei create little fireballs with temperatures 100 000 hotter than the centre of sun
•At this temperature, the protons and neutrons of the Lead nuclei
melt into their elementary components, the quarks and gluons
creating a state of matter called Quark Gluon Plasma for a very
brief instant of time. •Such state of matter must have existed at the extreme
temperatures of the early Universe a few microseconds after the
Big Bang
