Qm virtual particle force on wire, acrose the universe

Click For Summary

Discussion Overview

The discussion revolves around the concept of virtual particles and their hypothetical force on a wire extending from Earth to a distant part of the universe receding at near light speed. Participants explore the implications of cosmic expansion on such a wire and the relevance of quantum mechanics (QM) to the scenario.

Discussion Character

  • Debate/contested, Conceptual clarification

Main Points Raised

  • Lachlan questions the virtual particle force on a wire extending across the universe and seeks to understand the implications of such a scenario.
  • Bill asserts that virtual particles do not exist and suggests that the wire would not break due to the relativistic nature of velocity.
  • Lachlan acknowledges Bill's point about virtual particles and shifts the focus to the effects of expanding space on the wire, questioning the reference frames involved.
  • Bill clarifies that while the universe is expanding, this expansion does not affect objects within that space and recommends that the discussion may be better suited for the relativity forum.

Areas of Agreement / Disagreement

Participants express disagreement regarding the existence of virtual particles, with Bill denying their existence while Lachlan initially considers them. There is also a lack of consensus on how cosmic expansion affects the wire, with differing views on the relevance of quantum mechanics to the issue.

Contextual Notes

The discussion includes assumptions about the nature of virtual particles and the effects of cosmic expansion, which remain unresolved. The participants do not reach a definitive conclusion regarding the implications for the wire.

What would be the virtual particle force acting on a wire, which go's from say Earth to any part of the universe reseeding away from us at near light speed, or grater ?, would it break,
and how would we compute it ?

Virtual particles don't exist as has been discussed in numerous threads on this forum.

Since any velocity is stationary in its frame it wouldn't break.

Thanks

Thanks bill.
Ok, virtual particles, have no part to play here. As you state they don't exist
So, I suppose the ? becomes are case of our expanding space, reference point verse, the far end the wire expanding space reference point.
So not a ? QM can help with.

Thanks

The size of the universe is expanding - but that has no effect on objects occupying that space:

This isn't really a QM issue - you should post over on the relativity forum. Also see if you can make your query more specific.

Thanks
