A question of Black holes.

[enigma10]

We know they exist.<br /><br /> we know they consume almost all matter they come in contact with.<br /><br /><br /> But what happens if 2 black holes collide? Would one rip apart another and make its mass its own, like a star, or would the 2 cause an explosion of some sort? <br /><br /> Can a black hole reach a point where the fuel for fusion reaction can begin again and overcome the gravity? A reborn star? A big bang?<br /><br /> I'm looking around to answer my queries, but thought any input here could help me. Thanks.<br /><br /> <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

When two black holes collide,they form a larger black hole,adding up their mass.At the time huge amount of gravitational waves are released.

 

[enigma10]

Yes. I've located a few articles of interest to answer most of my querries.<br /><br /> Gravity waves <br /><br /> When they collide <br /><br />This link will give a short answer for almost any question concerning a black hole <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

Gravity wves are all pervasive.They spread throughout universe.Some are hanging in earth.So be cautious.

I've heard this question posted at least a hundred times...and the answer is easy if thought through in the rigt order:<br /><br /><font color="yellow">1.<font color="white"> Realize that blackholes are NOT really holes.... They are heavenly bodies just like planets.<br /><font color="yellow">2.<font color="white"> What happen if two planets combine....

They most likely don't exist as an actual hole. Although, we could look at them as being holes in 4th dimension spacetime. The larger the mass, the more it warps spacetime around it. For example, the Sun warps spacetime much more than Earth does because it is so much more massive. Blackholes should theoretically warp spacetime infinitely. So, we could kind of say that if spacetime is warped infinitely, it creates a bottomless pit in the 4th dimension. <br /><br />I once heard that our perception of the planets rotating in circles around the Sun is only in terms of 3 dimensions. Theoretically, the planets are traveling as straight as they can go, but because of the warp of spacetime from the Sun, it appears to us that they travel in circles. <br /><br /> <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

Wrong line of thinking .Its not a hole.It is seated in 10 to the power minus 33.We call it singularity.

I felt gravity of the black hole would alter greatly the results of such collisions. So far, from what i can find, the answer is when they 2 bodies collide, speed, structure, and impact parameters are irrelavent for the end result. They combine eventually due to the tremendous gravity.<br /><br /> As i stated in my follow up reply, i had concluded the researching and found my answers, but thanks for your reply all the same.</p></p> <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

Right Alok, I understand that it's not physically a hole. The idea that I was stating is from a model that is commonly used to help visualize the warping of spacetime. Spacetime can be visualized as a flat rubber sheet. Take our Solar System for instance, each planet makes an indentation in the rubber sheet due to its mass. The Sun at the center of the rubber sheet would make an indentation far larger than any of the planets. So, with a black hole, it would basically create an indentation that was infinite. In otherwords, it would create a bottomless hole. <br /><br />Imagine being out in the ocean and being sucked into a whirlpool that was infinitely deep. This is the same idea as the rubber sheet analogy <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.

A stone placed on a rubber sheet may extend to million of kms.It defies all known geometry.Even non Euclidian geometry fails.Only Wheeler knows what is inside.

 

[enigma10]

I tend to think this one of the more popular theories.<br /><br /><i><font color="yellow">The caviat to this is that Stephen Hawking thinks that once matter falls into a black hole and reaches the Singularity, this Singularity at the quantum scale may actually become a gateway or a spawning ground for a new universe which would exist in some adjacent set of spacetime dimensions. Black holes formed in our universe, according to Lee Smolin, may actually spawn universes beyond our own. I can't imagine any way to test such a conjecture because we can only make observations within our own spacetime.</font></i> <br /><br /> My personal opinion is a black hole is not a hole in any sense except in its influence over universal forces and laws. The reason for this is because if it was a gateway, we should be able to observe a similar phenomena within our own universe. I feel they are simply a "strong crunch" star.<br /><br /> I also believe these are not "bottomless holes" , since such a conjecture would dictate no increase in mass or gravity would be viewed. They would all be one size. This is disproven by simple observation of known black holes. This would also make the possibility of a singilarity being created impossible, since a "bottomless hole" would be the result. <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

Singularity is proven fact.If you can pass throgh it you may reach another universe.But there is no other end to the singularity.Spacetime cease to exist then.You cant cross singularity.

Im sorry if my response seemed like a "wiseguy" sort of thing...<br /><br />That is just the way I think if I had known exactly what questions you were trying to ask I wouldn't have insulted you, but dead stars are still heavenly bodies. I was just using a way of descriibing such an event in a way I can comprehend.<br /><br />In truth while the blackholes may collide they may not neccesarilly form a bigger blackhole. We don't know how a black hole is on the inside. It might pull in so much time and space that it creates a rip in time and space. If this is true than things can happen that would not normally be posible as the universe disolves.<br />If though our laws hold a bigger hole should be formed.<br />As for what will happen when they collide?<br /><br /><font color="yellow">...I can only Imagine the power released when two infinitely dense masses collide with each other at nearly the speed of light or Greater......?<br /><br /><br /><font color="white"> Oh and sorry for insulting you intelligence.......and yes the end result is the same...we think?</font></font> <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>

A singularity is an infinitely small point...<br /><br />In blackhole terms it is when the point in which all the mass whithin the blackhole is contained. Gravity packs down and compresses the mass of this body.<br /><br />Welcome to SDC (space.com) renato... <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>

 

[enigma10]

Though singularities are a proven fact in the sense of the terms they endear, the probability of one existing in a black hole is only a theory, and should only be viewed as such.<br /><br /> For a decent definition of a Singularity try this link..<br /><br />Gravitational Singularity and links to its varied terms<br /><br /> More importantly i wish to reflect this thought.<br /><i>Many theories in physics have mathematical singularities of one kind or another, in which the equations predict that the rate of change of some quantity becomes infinite or increases without limit. This is generally a sign for a missing piece in the theory, as in the Ultraviolet Catastrophe and in renormalization.</i> <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

 

[alokmohan]

Earliest fname of black hole was schwrzchild singularity.Singularity is loosely said ,cenrter of black hole.

 

[enigma10]

Of course. Pity Schwarzchild wasn't with us a few more years. I feel we lost time before his shoes were finally filled again. <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>

Wheeler is living .He is inspirer.He coined the term black hole in 1967.

 

[savor]

Black holes is energyscentrum who getting bigger and bigger all a time, like all atoms doing all a time.<br /><br />Star expanding guiglier what black holes, because black holes energy is so solid, that this very solid energy can keep it self very hot and very solid longer what stars energy can. All stars and black holes who borning when star expanding supernovas, moving far a way galaxys centrum, but they are getting bigger same time, and that why stars and black holes not going far a way galaxies centrum, even they moving off galaxies centrum.<br /><br />Also, you can moving yours body and you can going solid, when you are not losing yours energy that guigly.<br /><br />Savor<br /><br />

 

[savor]

Black holes expanding all a time like atoms and black holes open very solid energywawes and this very solid energywawes are very energy small energycentrum, what we realise some time coming to earth.<br /><br />This black holes energywawes very energy small energycentrum are not opening own energywawes so guicly what stars fotons open own energywawes and that why fotons pushing themselfs to black holes and again this happenning because light energywawes have a pressure.<br /><br />Savor<br /><br /><img src="/images/icons/smile.gif" />
