• Question: At absolute zero, do the electrons stop spinning around the nucleus, because if it didn't, then surely there would still be enery there so it wouldn't be absolute zero, but then if it did stop, then wouldn't the atom go weird?

      Very good question! The electrons never stop spinning around the atom. Yes, there is still energy in the atom. But that energy can not be used outside. From the outside point of view, all the atoms are at rest, so it is zero absolute.

      Great question. The problem you brought up is exactly why you can never actually get perfectly to absolute zero, only very very close to it.
