Can energy change physical laws?

Click For Summary

Discussion Overview

The discussion revolves around the question of whether huge amounts of energy could alter the fundamental nature of the universe, including its physical constants, laws, and dimensions, and whether such changes could lead to the existence of a multiverse of various levels.

Discussion Character

  • Debate/contested
  • Exploratory

Main Points Raised

  • Some participants propose that large amounts of energy could change the universe's nature, potentially enabling a multiverse of different levels.
  • Others question the premise, asking why energy would have such an effect and noting that multiverse theories are hypothetical with no empirical evidence.
  • A participant expresses skepticism towards multiverse theories, particularly emphasizing the many-worlds interpretation of quantum mechanics but questioning the value of unobservable universes.
  • One participant argues against the idea that energy can change fundamental laws, stating that energy is a dimensionful quantity and that discussions should focus on dimensionless quantities like the fine structure constant.
  • A later reply critiques the speculative nature of multiverse theory, suggesting that discussions should be grounded in peer-reviewed research rather than Wikipedia references.

Areas of Agreement / Disagreement

Participants express a range of views, with no consensus reached on whether energy can change the universe's nature or the validity of multiverse theories. The discussion remains unresolved with competing perspectives presented.

Contextual Notes

Limitations include the speculative nature of multiverse theories, the dependence on definitions of energy and dimensions, and the lack of empirical evidence for claims regarding changes to fundamental physical laws.

Could huge amounts of energy change the universe's nature (fundamental physical constants, laws, dimension)? Could it change it so much that it would enable our universe to be a multiverse of level 1, 2, 3 or 4?

why would it ?

since multiple universes are only hypothetical and there is no evidence for them, your Q cannot be answered

I don't subscribe to all those "multiverse" theories. The only one that makes some sense to me is the level 3 many-worlds interpretation of QM, but what good is it to have other "mathematically possible" universes that we have no way to observe or otherwise prove the existence of?

No. Energy has dimensions. For example, the SI unit is the joule, which is of course an arbitrary amount chosen by people, not by Nature. So to have a large amount of it means that you have a large amount compared to an arbitrary amount, so the notion of a large amount of a dimensionful (as opposed to dimensionless) quantity is entirely arbitrary.

When you look at issues like this you need to look at dimensionless quantities, like the fine structure constant. If it had a different value our universe would be an entirely different place. It may not even be possible for it to exist.
 
Multiverse theory is speculative. Discussion of a particular peer-reviewed paper that explores it might be ok, but discussion based on Wikipedia is not.

Thread closed.
