Does this paper disprove the possibility of a new universe creation?

Click For Summary

Discussion Overview

The discussion revolves around the implications of a specific paper on the possibility of creating new universes through quantum fluctuations and tunneling, particularly in the context of heat death and De Sitter Space. Participants explore theoretical frameworks and the credibility of the paper's claims.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant questions whether the paper disproves the possibility of universe creation through quantum fluctuations after heat death, and whether quantum tunneling could still occur under such conditions.
  • Another participant expresses skepticism about the "fecund universe" idea, suggesting that the paper introduces significant doubt but acknowledges the speculative nature of its content.
  • A request for clarification on the relationship between quantum tunneling and quantum fluctuations is made, indicating a need for further exploration of these concepts.
  • It is proposed that quantum tunneling can occur to a lower-energy vacuum state, which could have destructive consequences if it happens within the cosmological horizon, while tunneling to a higher-energy state is deemed impossible in this context.

Areas of Agreement / Disagreement

Participants express differing views on the implications of the paper, with some questioning its credibility and others acknowledging its speculative nature. The discussion remains unresolved regarding the validity of the claims made in the paper and the conditions under which quantum tunneling may occur.

Contextual Notes

The discussion highlights uncertainties regarding the definitions of quantum fluctuations and tunneling, as well as the speculative aspects of the paper in question. There are unresolved questions about the implications of the paper's claims on existing theories of universe creation.

My question has multiple parts, does the following paper:

https://arxiv.org/abs/1405.0298

Disprove the possibility of creation of another universe through quantum fluctuations if heat death occurs?

If it does could another universe still be created through quantum tunneling?

Can quantum tunneling exist without quantum fluctuations in De Sitter Space?

How credible is this paper? Are there any that refute the authors claims?

My general feeling is that it puts the "fecund universe" idea into serious doubt, but there's too much speculation in the paper to be certain. I would consider the paper to be one requiring serious consideration by anybody who is proposing a new idea for how new universes might form.
 
Do you have any knowledge on quantum tunneling? Can it exist without quantum fluctuations?

What is some of the speculation in the paper?

Thanks for the reply.

Quantum tunneling can still exist if it's to a lower-energy vacuum state, if such a state exists. If tunneling to a lower-energy vacuum state were to occur somewhere within our cosmological horizon, the lower-energy vacuum state would spread outward at very close to the speed of light and destroy everything within the original tunneling event's horizon.

Quantum tunneling to a higher-energy state can't exist in this model because there aren't fluctuations that raise energy.
