Gravitational waves and the multiverse

Click For Summary

Discussion Overview

The discussion revolves around the potential connection between gravitational waves and the multiverse hypothesis, specifically regarding whether events occurring within black holes could lead to the detection of gravitational waves by the LIGO observatory. The scope includes theoretical implications of black holes, multiverse concepts, and gravitational wave detection.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that if the multiverse hypothesis is true, singularities at the centers of black holes could give rise to "baby universes," potentially detectable by LIGO.
  • Others argue that a sound response to the initial question requires a reference to a multiverse theory that predicts such events, emphasizing the need for peer-reviewed publications.
  • A participant suggests reframing the question to explore whether any events predicted by general relativity (GR) could occur entirely within a black hole and still produce gravitational waves detectable outside.
  • Some participants note that there is no singular, well-defined "multiverse hypothesis," and that the ability to detect gravitational waves from external universes would depend on the specific model being considered.
  • One participant highlights that the concept of baby universes from black holes is exotic and lacks a proper working model, suggesting that detection of such events may not be feasible.

Areas of Agreement / Disagreement

Participants express disagreement regarding the existence and definition of a multiverse hypothesis, as well as the feasibility of detecting gravitational waves from events inside black holes. The discussion remains unresolved with multiple competing views presented.

Contextual Notes

Participants note limitations in the discussion, including the lack of a unified multiverse theory and the dependence on specific models for claims about gravitational wave detection.

Assuming that the multiverse hypothesis is true and a singularity at the center of a black hole can give rise to another baby universe. Can we detect such an event in the LIGO observatory?
 
Astronomy news on Phys.org
To get a sound response, you need to cite a reference that claims there is a multiverse theory predicting a singularity can give rise to a baby universe.

Valid references are peer reviewed publications.

I suggest a better question (and I myself don't know the answer or I would offer it) might be -

Is there any event that might occur entirely inside a black hole that GR predicts could cause gravity waves outside the black hole?

As far as I know, there is no single "multiverse hypothesis" that leads to a fully fleshed out physical theory. You would have to specify exactly which theory you were asking about in order to get any answers since whether or not "external universes" can be detected via gravitational waves would be entirely model/theory dependent.

There are a couple of completely unrelated ideas that would all lead to the existence of things you could call separate universes. There is no "multiverse hypothesis".

Baby universes from black holes are among the most exotic ideas, and they don't really have a proper working model. We also couldn't detect that.
