Waldo Posted March 23, 2006 Share Posted March 23, 2006 What If, and this is a big If, the ENTIRE UNIVERSE were consumed by black hole, would it still evaporate? This question drives me crazy? Link to comment Share on other sites More sharing options...
Klaynos Posted March 23, 2006 Share Posted March 23, 2006 the entire universe couldn't be swallowed by a black hole, because what would the black hole exist in? If you mean what would happen if all the matter in the universe was sucked into a black hole would it still evacuate? Then yes it would... Link to comment Share on other sites More sharing options...
Waldo Posted March 23, 2006 Author Share Posted March 23, 2006 I'm sorry, yes i meant all of the contents of the universe. Would it be possible that all of the energy of the universe was sucked in to the black hole? If so could it again evaporate? Link to comment Share on other sites More sharing options...

Stage 5 being the total uniform distribution of the photons produced from the evaporation. So the answer is yes Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
5614 Posted March 23, 2006 Share Posted March 23, 2006 There is a process known as Hawking Radiation whereby all black holes evaporate. It is named after Stephen Hawking who proved it could exist (theoretically). So in this case, and any case, the black hole would evaporate.

Either we get crushed into a singularity or we go on expanding for eer untill all the universe is filled with radiation... great choices It should be noted that the latter, if true, would probably last MUCH MUCH longer then the big crunch idea.

Waldo Posted March 24, 2006 Author Share Posted March 24, 2006 From what i understand black holes evaporate due to vacuum fluctuations. Could these fluctuations happen if the entire energy of the universe were in the black hole, iguess is the real question. Thanx Link to comment Share on other sites More sharing options...

Thanx Yes there is no such thing as empty space, everything has something in it - vaccum fluctuations for example. Quatum fluctuations always occur as is my understanding.

Waldo Posted March 25, 2006 Author Share Posted March 25, 2006 Your answer makes al ot of sense but i am still confused. I guess the question i could ask would be if there was no energy in the universe would the universe exist? I guess it wouldnt but what do you think. Thanx for you response though Link to comment Share on other sites More sharing options...

I guess it wouldnt but what do you think.Thanx for you response though Well yes - the universe can't ever be empty, there are always things in it to prevent it being so. There are vaccum fluctiation, virtual particles created and detroyed etc. Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
JesuBungle Posted April 30, 2006 Share Posted April 30, 2006 I don't mean to sound like a hippie. But imo, the universe is only energy. Anything that is, is energy. So how sure are you that there would be a universe without energy. Would there be any existance as we know it. I guess it could go either way, but I'm the type of guy that can't accept one theoretical answer. Link to comment Share on other sites More sharing options...
