This Hangout takes us well into the past, as we delve into the very early Universe. The LHC can recreate these early-Universe conditions in the lab by colliding heavy ions together. But why do we collide these different particle species? What is in store for the heavy-ion collisions after the end-of-year break? What is this mysterious quark-gluon plasma?
CERN's Quantum Diaries blogger and ATLAS physicist Pauline Gagnon is joined by theorists Urs Wiedemann and Stefan Floerchinger, as well as experts from the LHC's heavy-ion experiment, ALICE: Despina Hatzifotiadou, Antonin Maire, David Dobrigkeit Chinellato, Leticia Cunqueiro Mendez and Kenneth Read. Also connecting are ATLAS physicists Steven Goldfarb and Tiina Wickstroem from the Science Museum in London with content developer Alice Lighton, as well as Fraser Cain, publisher of Universe Today.
Recorded live on 6th December 2012.
The hangouts with CERN answer questions received via #askCERN on Twitter and Google+ and via YouTube and Facebook comments.
