Is it because at absolute zero you would know with certainty the momentum and the position of the particle? Or is there another reason? Would we ever be able to overcome the Heisenberg uncertainty principle?
In: Physics
The uncertainty principle does add a pretty decent reason behind why we cannot reach absolute zero, leading to zero-point energy.
However, we can use thermodynamic arguments with entropy and the third-law to show that any closed system cannot reach zero by any procedure in a finite number of finite operations. This is kind of a macro-level explanation really as opposed to the QM level explanation, but they’re essentially equivalent.
There’s probably some level of explanation towards this in QFT too, ie quantum foam.
