  • Absolute Zero is -273.15c (which means no energy -by heat- at all) 0K. There are still several theories for before the big bang: My preferred choice (but not the only one that exists), is that one universe was sat at a temperature very close to absolute zero (and sat like this for a very long time) most atoms being at a very low energy level (because of the temperature) and most atoms being Hydrogen (though some may be more complex). Another universe moving through timespace (also possibly at a very low energy level) collided with it (causing the big-bang) and so many atoms collide & merge to higher densities causing stars & planets to start (also with the creation of stars, you get the creation of other elements, solar systems planets heat etc...) So before the big-bang is possible, there are several theories as to what happened before it & above you have a (very basic) description of one theory.
