Vacuum energy and Energy conservation

Click For Summary

Discussion Overview

The discussion centers around the concept of vacuum energy and its implications for energy conservation, particularly in relation to vacuum fluctuations and the uncertainty principle. Participants explore whether these fluctuations can lead to violations of energy conservation, referencing both theoretical perspectives and experimental evidence.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants mention that vacuum energy fluctuations, which involve the creation and destruction of virtual particles, are said to violate energy conservation based on the energy-time uncertainty principle.
  • Others challenge the validity of references that claim vacuum fluctuations violate energy conservation, emphasizing the need for credible sources to support such claims.
  • A participant questions whether vacuum fluctuations themselves violate energy conservation, indicating a desire for clarification on this specific aspect.
  • There is a call for valid references to facilitate a more informed discussion, with one participant suggesting that without such references, the conversation lacks a solid foundation.

Areas of Agreement / Disagreement

Participants express disagreement regarding the interpretation of vacuum energy fluctuations and their relationship to energy conservation. There is no consensus on whether these fluctuations violate energy conservation, and the discussion remains unresolved.

Contextual Notes

Some claims rely on interpretations of the uncertainty principle, and the discussion highlights the need for clear definitions and valid references to support various viewpoints. The conversation also reflects a concern over the credibility of sources cited in the debate.

TL;DR
I understand from Noether's theorem, energy is not conserved in big scale space-time (because space-time is not static in big scales).
Also, I have heard from physicists that vacuum energy fluctuation (creation and destruction of virtual particles) violates energy conservation. The reason, they justify, is based on uncertainty principle (energy-time form of uncertainty principle), energy can exist and disappear for a very short period of time.
Could somebody explain this in simple words please?

This is not an acceptable referende. How are we to track that down and figure out where the misunderstanding is.

They do not.

Thanks Vanadium 50
How about vacuum fluctuation, does it violate energy conservation?

As has already been pointed out, this is not a valid reference. Without a valid reference we have no basis for a discussion.

For that reason, I am closing this thread. @Ebi Rogha, if you have a reference, please PM me and I will look at it, and if it looks OK, I will reopen the thread so you can post it.
