Recent calculations of BB conditions at the start: -"When the universe was less than one microsecond old and more than one trillion degrees, it transformed from a plasma of quarks and gluons into bound states of quarks - also known as protons and neutrons, the fundamental building blocks of ordinary matter that make up most of the visible universe-"Below this temperature, quarks and gluons are confined, existing only in hadronic bound states such as the familiar proton and neutron. Above this temperature, these bound states cease to exist and quarks and gluons instead form plasma, which is strongly coupled near the transition and coupled more and more weakly as the temperature increases."- Read more at: http://phys.org/news/2014-08-conditions-birth-universe.html#jCp
