Discussion Overview

The discussion explores the theoretical possibility of black holes expanding in negative dimensions, potentially leading to the creation of a negative universe. It touches on concepts related to black hole physics, singularities, and speculative ideas about the nature of such a universe.

Discussion Character

  • Exploratory
  • Speculative
  • Debate/contested

Main Points Raised

  • One participant proposes that as a star contracts into a black hole, it could theoretically continue contracting into a negative dimension, creating a negative universe that resembles a big bang from the perspective of its inhabitants.
  • Another participant argues that this idea is purely speculative, as the physics of black holes does not extend to the singularity, and emphasizes the need for a theory of quantum gravity for clarity.
  • Concerns are raised about the inability to test such a hypothesis due to the nature of black holes, where no light can escape past the event horizon.
  • One participant dismisses the initial proposal with a short answer of "no" and suggests it resembles the question of whether we are inside a black hole.
  • There is a light-hearted exchange about the terminology used, including the correct spelling of "black hole" and "Occam's Razor."
  • Another participant acknowledges the speculative nature of the discussion and questions whether the laws of physics would be the same in a negative universe.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of the initial proposal, with some outright rejecting it while others entertain the speculative nature of the idea. The discussion remains unresolved, with no consensus on the validity of the concepts presented.

Contextual Notes

Participants note that the discussion involves speculative science and personal theories, which may not align with the forum's focus on mainstream STEM subjects. There is an acknowledgment of the limitations in testing such ideas due to the inherent properties of black holes.

I know this is far from what a strict obeyance to the principle of occoms razor may result in and its probably wrong. is it theoretically possible that as a star contracts to result in a black hole, the contraction does not stop when its just a point hole, but continues, expanding in a negative dimension, increasing in negative size and giving rise to a negative universe? To inhabitants of such a universe, if such is possible, its birth would resemble our big bang, right?

Interesting thought but its pure speculation since the physics of black holes doesn't extend to the point of singularity so we just don't know.

Perhaps once we discover the theory of quantum gravity then things will become more clear.

Even if we could design an experiment to test out your thought no light signals would ever escape for us to view since the escape velocity, once you're past the black hole event horizon, is greater than the speed of light itself so basically you'd never be able to tell us what happened.

However, you could use it as a premise for a cool science-fiction story realizing that you'd have to violate one or more principles of physics to make it interesting.

Also please be aware that PF doesn't dwell on speculative science or personal theories and will often close threads related to it. PF is focused primarily on helping students understand mainstream STEM subjects.

Oh, the gravity of it all that causes the space between the words black hole to disappear into the void of malapropism...
 
jedishrfu, lol.. black>-----<hole
Anyway, i know this can never be objectively tested, hence the words theoretically (although, i did allude to my speculation that this could have actually happened to our universe)

Simon, thanks, ill read up on it.

PS: Do you think the laws of physics inside such a universe would be the same?

... yeah, we'll be telling Uranus jokes next.

... the word "speculation" is more appropriate here than "theory". Take care with speculations on PF.

The link I provided has the background and a short discussion on the questions you raise here.
It is also well discussed in these forums and elsewhere online, you should investigate.
