Black Holes and White Holes

[WinstonSmith]

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?

[Graviphoton]

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.

white holes are not well thought of in astrophysics circles... IIRC they break the second law of thermodynamics.

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).

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.

Hear, hear!

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.

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]

INow... no no. I knew that already. I was wanting a reference to, white holes looking like black holes to an observer

[insane_alien]

try the first two references on the wikipedia page.

[Klaynos]

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!

[Graviphoton]

Oh right... thanks

This is teh first time I've heard of white holes...very interesting concept.

[antimatter]

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]

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

[Klaynos]

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...

Right.. thermodynamics..

[Klaynos]

That and no evidence either experimental or theoretical other than people thinking they'd be a nice idea....
