Reply to comment by jonnyclueless in In the absence of cosmic radiation, would an object placed in space eventually cool to absolute zero? by IHatrMakingUsernames

Absolute zero would mean that the particle would not be moving. That violates the Heisenberg Uncertainty Principle, which states that the position and momentum of a particle cannot be known below a certain value.

And the minimal energy that remains as a result of this is called "zero point energy", as it's the lowest possible energy state (but not "zero energy")

Is that an unbreakable law? Alternatively, could we stop being able to determine where it is, like a Bose-Einstein condensate but on a macro level?
