What really happens?

What do you mean? All atomic motion would, in theory, stop. However you can never reach absolute zero, it is impossible, so lets not guess.

 

Well that is based upon the fact that at absolute zero you would know the exact location and momentum of electrons which would break the rules of the Heisenberg Uncertainty principle. I think it's a better idea to say 'We may reach absolute zero, but we'll never be able to tell that we did as the act of making a measurement will bring whatever we're measuring above absolute zero.'

'We may reach absolute zero, but we'll never be able to tell that we did as the act of making a measurement will bring whatever we're measuring above absolute zero.'

So all we have to do is separate information from energy(states) so we can transfer information wihtout transferring energy. :rolleyes:

According to quantum mechanics if you cannot observe it you cannot say it exists.

 

But the Third Law of Thermodynamics (combinded with the Second) say that absolute zero can only be approached as a limit and never obtained.
