Discussion Overview

The discussion revolves around the concepts of black holes and white holes in astrophysics, exploring their theoretical implications, potential existence, and relationships to phenomena like the Big Bang. Participants engage with speculative ideas and hypotheses regarding these celestial bodies.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant expresses a strong interest in black holes and white holes, suggesting that white holes could serve as a means of transport between points in spacetime and possibly different universes.
  • Another participant argues against the existence of white holes, stating that they would violate the second law of thermodynamics.
  • A participant questions the visibility of a white hole, proposing that if one were nearby, it would be excessively bright.
  • There is speculation about the possibility of our universe existing within a black hole, prompting further inquiry about the nature of black holes and their implications for our universe.
  • One participant suggests that quasars might actually be white holes rather than supermassive black holes, presenting an alternative hypothesis.
  • Another participant inquires about the need for sources to support claims made in the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the existence of white holes, with some proposing their potential existence and others arguing against it due to thermodynamic considerations. The discussion remains unresolved regarding the nature and implications of black holes and white holes.

Contextual Notes

Some claims rely on speculative reasoning and hypothetical scenarios, such as the relationship between black holes, white holes, and the Big Bang, which may not be universally accepted or proven.

i like astrophysics so much! But have particular interest in black holes and white holes and the big bang!


In astrophysics, a white hole is a postulated celestial body that spews out matter, in other words an anti-black hole, or the time reversal of a black hole.

It can be a means of transport between points of spacetime and even different universes. A matter that enters through a black hole might come out of a white hole. For example an astronaut that got suck into a black hole will come out of a white hole. Although, sadly, he would be crushed up terribly, but the exact number of atoms that made up his body will come out of the white hole. The existence of white holes is hypothetical, as they appear to violate the second law of thermodynamics but the laws of physics that apply in our bubble universe will not be the same in other bubble universe.

Other speculations include the hypothesis that quasars are actually white holes instead of supermassive black holes.

It is possible that a white hole is created out of an anti-matter star when it explodes. As it is the opposite of a black hole. An "anti-black hole". white holes have a high chance of existence in our universe as you can say our universe is created out of a massive white hole. The Big Bang which spews out matter.

although my article talks about white holes, i don't think its possible for them to exist as they would violate the second law of thermodynamics!
 
Welcome to physicsfourms,Whiteholes(Frist time there is a username that has sam the name as his frist post and not being about him/her self)
Good article you worte but can you put links to your sources?
 
Well we would know if a white hole was near, because everyhting would be too bright, right?

I was just thinking about white holes the other day while looking at this photo

So is it possible for us to be in a black hole ( our "Universe")?

what do you mean? A black hole in our universe? Or we live in a black hole?
