White Holes created our Universe

Click For Summary

Discussion Overview

The discussion revolves around the concept of white holes and their potential role in the creation of our universe, particularly in relation to black holes and the Big Bang. Participants explore theoretical implications, definitions, and the speculative nature of these ideas within the frameworks of general relativity and quantum mechanics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant describes white holes as hypothetical regions of spacetime that cannot be entered from the outside, proposing that they may be the reverse of black holes and suggesting that the Big Bang could be a manifestation of a white hole.
  • Another participant challenges the idea, labeling it as unsupportable personal speculation.
  • A third participant provides a definition of white holes from a source, noting that while they appear in the theory of eternal black holes, there is no known physical process for their formation, making the hypothesis difficult to support.
  • A later reply counters the previous skepticism by referencing existing papers that discuss the concept of white holes, implying that there is some academic interest in the topic.

Areas of Agreement / Disagreement

Participants express disagreement regarding the validity of the white hole hypothesis, with some viewing it as speculative and unsupported, while others reference academic literature that may lend it some credibility. The discussion remains unresolved with multiple competing views present.

Contextual Notes

Participants highlight the lack of known mechanisms for the formation of white holes and the speculative nature of linking them to the origins of the universe. There are references to theoretical frameworks that may not have empirical support.

In general relativity, a white hole, is a hypothetical region of space-time which cannot be entered from the outside; but matter and light can escape from it. In this sense, it is the reverse of a black hole, which can be entered from the outside, but from which nothing, including light, has the ability to escape.

In quantum mechanics, the black hole emits Hawking radiation and so can come to thermal equilibrium with a gas of radiation. Because a thermal-equilibrium state is time-reversal-invariant, Stephen Hawking argued that the time reverse of a black hole in thermal equilibrium is again a black hole in thermal equilibrium. This implies that black holes and white holes are the same object.

The possibility of the existence of white holes was put forward by I. Novikov in 1964. White holes are predicted as part of a solution to the Einstein field equations known as the maximally extended version of the Schwarzschild metric describing an eternal black hole with no charge and no rotation.

When a black hole forms, a big bang may occur at the core, which would create a new universe that expands outside of the parent universe.

Could the Big Bang itself be a white hole. Could our universe have been created as a result of another universe being devoured by a black hole?

The emergence of a white hole, which was named a 'Small Bang', is spontaneous—all the matter was ejected at a single pulse. Thus, unlike black holes, white holes cannot be continuously observed—rather their effect can only be detected around the event itself.

How many of you support this theory and should we work on identifying a new group of gamma-ray bursts that may be associated with white holes.

This is unsupportable personal speculation.
 
From wiki:

In general relativity, a white hole, is a hypothetical region of spacetime which cannot be entered from the outside; but matter and light can escape from it. In this sense, it is the reverse of a black hole, which can be entered from the outside, but from which nothing, including light, has the ability to escape. White holes appear in the theory of eternal black holes. In addition to a black hole region in the future, such a solution of the Einstein field equations has a white hole region in its past.[1] However, this region does not exist for black holes that have formed through gravitational collapse, nor are there any known physical processes through which a white hole could be formed.

It's kind of hard to support a hypothesis involving an object that has no known way of coming into existence.
