What would happen when two blackholes collide?

Question

feel free to answer as if they were identical or if one was larger then the other.

Answer 1

Two black holes colliding would simply merge into a single much more massive black hole. See this website for a computer animation ==>http://chandra.harvard.edu/photo/2002/0192/

Answer 2

When two black holes collide they merge to form a single larger black hole. As proven by Steven Hawking in his famous book "The Large Scale Structure of Space-Time" the surface area of the event horizon of the resulting black hole will be greater than or equal to the sum of the surface areas of the original black holes. In the process of the collision gravitational waves will be given off until the resulting black hole settles down to its final state.

Gaurav Khannay, Reinaldo Gleiserz, Richard Price and Jorge Pulliny studied the Collision of two grazing Black Holes and determined that the energy radiated from the collision is probably not more than 1% of the total mass of the system, and the angular momentum radiated is not more than 0.1% of the initial angular momentum.

The final stages of the collision of two black holes can be approximated using perturbation theory. The idea behind what is now commonly referred to as the "close-limit" approximation is very simple. Assurne that the two black holes are surrounded by a common horizon. If so, they can be considered as a single perturbed black hole.In this picture, the full problem is reduced to an initial-value problem for what is called the Zerilli equation. This problem can readily be solved, and the results compare favourably with fully nonlinear numerical relativity simulations. Why is this, seemingly naive, approximation such a success? A reasonable explanation is that the spacetime is only strongly distorted in the region close to the horizon. Because of the existence of the potential barrier outside the black hole most of this perturbation will be scattered back onto the black hole. The waves that reach a distant observer mainly originate from the region outside the peak of the potential, where the initial perturbation is much smaller and linearized theory is a reasonable approximation.

The close-limit approach was first used to study head-on collisions of two nonrotating black holes. It has subsequently been used to investigate other collision types.

Answer 3

There would probably be big gravity waves that we might be able to detect, and they would merge into one larger black hole. I use 'larger' in the relative sense. The event horizon might not be noticeably larger, but the mass of both would be combined into one. I suspect that there might also be an enormous burst of Hawking radiation as they merged. But as they moved toward each other (or one did most of the moving, if their masses were greatly different), space would have been cleaned out of other objects and materials for quite a wide area around, so the radiation would not threaten anybody or anything. They would already have been swallowed up.

Answer 4

a supermassive blackhole would have formed, but most blackholes have what they call as an element of singularity in the epicenter of it. they're only the size of a pinhole but has the mass of mars .they'll spark off each others' gravity and either annihilate each other, this is commensurate with the gravity equation , or form a greater , but unstable blckhole that might implode onto it self forming neutrinos, a ghost particle. Since this never happened before, this is only my conjecture, as im a rookie myself in these hyperspace stuff

Answer 5

i think of they had in simple terms exchange right into a much bigger blackhole with lots of the sum of the mass of the unique ones. The mass distinction (if any) might come from any power launch that would desire to result from the collision that became into released and escaped the gravity pull.

Answer 6

They merge and the singularity sends out some mega gravitational waves.

Answer 7

Gravitational waves would be produced. Collision of black holes is one way gravitational waves strong enough to detect from Earth could be produced.

Answer 8

Their gravity would have tried to pull each other and the one with a greater gravity would have got hold of the other.

Answer 9

I don't think that that could happen. I'm pretty sure that black holes aren't just floating around in space. I think that they're stationary.

Answer 10

a rip in the space time continuum would occur
