Is There Any Motion at Absolute Zero?

Click For Summary

Discussion Overview

The discussion revolves around the concept of motion at absolute zero (0 Kelvin), exploring whether any form of motion can exist in this state, particularly in relation to subatomic particles and their energy states.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants propose that absolute zero represents the minimum energy state for an object, suggesting that while particles would be in their lowest energy states, some motion may still occur due to the uncertainty principle.
  • One participant argues that even at 0 Kelvin, it is possible to move an object in a lab, implying that motion can exist externally, though this does not necessarily address internal particle motion.
  • A mention of zero point energy is made, indicating a potential area of exploration regarding energy states at absolute zero.

Areas of Agreement / Disagreement

Participants express differing views on the nature of motion at absolute zero, with no consensus reached on whether internal motion of particles can exist or how it relates to external motion.

Contextual Notes

There are limitations regarding the definitions of motion and energy states, as well as the implications of quantum mechanics, which remain unresolved in this discussion.

Is it possible for motion to exist at 0 Kelvin?

Yes, absolute zero is the MINIMUM energy state for an object, not a ZERO energy state. The subatomic particles would all be in their lowest energy states, but for some that state would still entail some motion I believe. I'm sure the uncertainty principle matters here somehow.

Well, if I had an object at 0 Kelvin (strictly speaking, some non-zero temperature that is very close to zero) I could still move it around my lab... So the answer has to be yes.

If you were asking about internal movement of the particles making up the object, then Drakkith has already answered.
 
zero point energy.
