Black hole feed limit

[ehcuob]

A black hole has met by coincidence a cluster of stars and then again a cluster of galaxies, it is now a super giant black star with an outward spiral atracted by more galaxies and more galaxies still converging inward and etc... <br /> The whole Universe is now in black hole state, but the super black hole over billions of years disipates by heat so now you have a hot universe the size of an atom that expands to form agian?

 

[alokmohan]

What exactly you want to state is confuing.You mean universe came out of supermassive black hole or even larger structure.Tell me first if you know what is white dwarf.This may be our first discussion.

Black hole lose mass much slower than they gain = accreate mass, except for Jupiter mass black holes (if there are any black holes with so little mass). Also some of the lost mass is eventually recaptured.<br />Most experts think it is very hot and very high pressure inside the event horizon, especially low mass black holes. Neil

 

[lukman]

perhaps the idea of black hole similar to the big contraction prior big bang. <div class="Discussion_UserSignature"> </div>

 

[alokmohan]

You mean after a black hole forms,it is a potential of big bang?I dont agree .Black hole may be inverted white hole and vice versa.

 

[enigma10]

I cant believe that until some form of a white hole is found. Finding one would be conclusive proof to alot of theories around black holes. <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

 

[lukman]

i dpnt mean that, btw, the white doesnt exist, making black hole theory not so right after all. <div class="Discussion_UserSignature"> </div>

I think there is no evidence whatsoever for white holes in our universe, despite the theories. Until I see some, they go below unicorns on the list <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

None has seen a black hole also.Some say end product is quark star not black hole.

I only have 50% faith to the existance of black hole. <div class="Discussion_UserSignature"> </div>

A black hole will clear clear out its neighborhood and nothing more. Your said cluster of galaxies would have to be migrating towards the original mass before it even became a black hole. An example would be our Sun becoming a black hole (impossible)... our orbit would not change as the mass would still be the same. <br /><br />Unless the entire universe is heading towards our Sun, your scenario is implausible. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

 

[alokmohan]

Einstein,Eddington would share your faith.But Wheeler is problack hole.He christened it as black hole.Kip Thorne is yhe advocate of black hole.

[enigma10]

<i><font color="yellow">A black hole will clear clear out its neighborhood and nothing more.</font></i><br /><br /> This would suggest a black hole is a non-mobile celestrial body within a universe of motion. I find this highly improbable. Based on just this aspect of your reply, the rest of it falls apart. <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

There are, indeed, local events in which a black hole will encounter new neighbors and devour them, too. Witness the center of our galaxy. I was speaking in terms of the very grandest scales of the observable universe. <br /><br />I believe the OP was proposing the idea of a runaway black hole gobbling up the entire universe. My post suggested that this scenario is entirely impossilbe... IMO. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

 

[dragon04]

I don't think it would be entirely "impossible" at least not in every single galaxy.<br /><br />But using the solar system as a model (and every other solar system we have detected so far), the Sun didn't suck every bit of matter into itself.<br /><br />The problem with creating a central massive BH that sucks everything in its host galaxy into itself would require a phenomena that we haven't observed in any other solar system or galaxy to date.<br /><br />I think we're safe from the Great Cosmic Vortex.<br /><br /> <div class="Discussion_UserSignature"> <em>"2012..

[alokmohan]

Why shall a black hole devour?It behaves l;ike normal celestial objects.Dont make it supernatural.

 

[enigma10]

My car devours my wallet in gas costs. Though i feel its supernatural sometimes, it isn't <img src="/images/icons/wink.gif" /> <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

 

[alokmohan]

You agree wallets are devoured by car,not poor black hole.Nobody visits such A NICE PLACE.

There is always The Great Attractor, but even that is still a local event that has no effect on the Universe as a whole. <div class="Discussion_UserSignature"> <div> </div><br /><div><span style="color:#0000ff" class="Apple-style-span">"If something's hard to do, then it's not worth doing." - Homer Simpson</span></div> </div>

 

[alokmohan]

If the grart attractor really exists.
