WinstonSmith Posted May 20, 2008 Share Posted May 20, 2008 I have recently read about a theory that involves a black and white hole in place where the Bermuda triangleis. Is this a sound theory? and if so would it account for a lot of anomalies in our planet? Link to comment Share on other sites More sharing options...
Graviphoton Posted May 20, 2008 Share Posted May 20, 2008 No. The gravitational attraction of earth, would couple with the black hole, and would inexorably mean that the black hole would fall into earth, and start to eat it up. Also, hypothetically lets say it doesn't, if the black hole isn't very big, it would very much eventually evaporate through gamma radiation production; the smaller the black hole, the quicker the evaporation of its mass. Therefore, the theory is totally bogus. And it certainly wouldn't be a white hole, because they spew out energy, not contain it. This effect would also be noticable.

Klaynos Posted May 20, 2008 Share Posted May 20, 2008 white holes are not well thought of in astrophysics circles... IIRC they break the second law of thermodynamics. Link to comment Share on other sites More sharing options...
Sayonara Posted May 20, 2008 Share Posted May 20, 2008 And it certainly wouldn't be a white hole, because they spew out energy, not contain it. This effect would also be noticable. That's not really an effective differentiation. To an outside observer, black and white holes appear the same. The only difference is what happens to attracted matter at the horizon. White holes will only "spew energy" in the sense you mean it when they die, and black holes emit Hawking radiation anyway (which you'd certainly hope we would notice).

WinstonSmith Posted May 20, 2008 Author Share Posted May 20, 2008 Thank you. again for clearing this up it seemed funny when I read it. though I am not a Scientist I am interested in all matters of Science. and It's nice to have a place like this.

Graviphoton Posted May 20, 2008 Share Posted May 20, 2008 Mmmm... not tha i don't believe you, but do you have any refence to the observational qualities of a white hole? I know more on black holes, than what i do white... itr would be interesting. Link to comment Share on other sites More sharing options...
iNow Posted May 20, 2008 Share Posted May 20, 2008 http://en.wikipedia.org/wiki/White_hole The existence of white holes that are not part of a wormhole is doubtful, as they appear to violate the second law of thermodynamics. ...Just as Klaynos said above.

Graviphoton Posted May 20, 2008 Share Posted May 20, 2008 INow... no no. I knew that already. I was wanting a reference to, white holes looking like black holes to an observer Link to comment Share on other sites More sharing options...
insane_alien Posted May 20, 2008 Share Posted May 20, 2008 try the first two references on the wikipedia page. Link to comment Share on other sites More sharing options...
Klaynos Posted May 20, 2008 Share Posted May 20, 2008 I have to say I think # ^ E. Fahri and A. H. Guth (1987). "An Obstacle to Creating a Universe in the Laboratory". Physics Letters B183: 149. sound fun! Link to comment Share on other sites More sharing options...
Graviphoton Posted May 20, 2008 Share Posted May 20, 2008 Oh right... thanks Link to comment Share on other sites More sharing options...
a Clown Posted May 22, 2008 Share Posted May 22, 2008 This is teh first time I've heard of white holes...very interesting concept. Link to comment Share on other sites More sharing options...
antimatter Posted May 25, 2008 Share Posted May 25, 2008 This is teh first time I've heard of white holes...very interesting concept. yes...quite... I was actually thinking about the possibility of white holes the day I found out about them (iirc, a long time ago). I was reading about black holes, and considered briefly the exact opposite of a black hole...then the next chapter was about white holes...

Dark matter Posted May 29, 2008 Share Posted May 29, 2008 I'm not sure if this is true or not, but i heard every black hole is a white hole if someone were to go backwards through time in a black hole... not sure Link to comment Share on other sites More sharing options...
Klaynos Posted May 30, 2008 Share Posted May 30, 2008 I'm not sure if this is true or not, but i heard every black hole is a white hole if someone were to go backwards through time in a black hole... not sure Sounds like bunk to me... Black holes radiate as black bodies, and have ejecting spurts from their accretion disks... don't see how you could run them backwards and get a white hole. Not that white holes exist of course...

Klaynos Posted June 2, 2008 Share Posted June 2, 2008 That and no evidence either experimental or theoretical other than people thinking they'd be a nice idea.... Link to comment Share on other sites More sharing options...
