I never really got how you can go beyond absolute zero. Temperature is the movement/agitation of atoms, absolute zero means the atoms are still and don't move anymore, by definition. Lower than absolute zero temperature should mean the atoms should be "more" still than still.
Which is nonsense to me.<p>And what's even more nonsense, it's that temperatures "lower" than absolute zero are hotter than absolute zero.<p>Can anyone explain this discrepancy ?
