In summary, if two black holes of the same mass fall in towards each other with no angular momentum, how much of the original mass/energy of the black holes will be left in the combined black hole after the merger and how much mass/energy will be lost in the form of radiation?

What would happen to the spacetime fabric when two super massive black holes collide. I know that they would orbit each other and the would produce gravitational waves.

Why do you assume they would orbit each other? Can you not envision a situation in which they come pretty much straight at each other? Give that each would have enormous gravitational attraction, doesn't a collision seem more likely than orbiting?

They WOULD orbit each other and would get near to each other until they finally collide, but this would be in a fraction of a millisecond. I am confirm about it as i have read it from a very authentic source but after the collision what would happen is a big question.

No it's not. After the collision they would merge.

Expanding on the subject of this thread. If we take the most simple scenario of two (uncharged, nonrotating) black holes of the same mass falling in towards each other with no angular momentum. How much of the original mass/energy of the black holes will be left in the combined black hole after the merger and how much mass/energy will be lost in the form of radiation? We assume that the two holes are falling in towards each other from being initally at rest with respect to each other and located (infinitely) far away from each other.

Does the answer depend on the masses of the two black holes?

Yes they would but their gravity WILL cause them to orbit each other. otherwise the gravity of sun does not attract us but keep is in orbit, rotating not falling in that. We would only fall when the spacetime fabric is curve enough. This can be seen from equations of gravity, like moon orbits Earth but the apple from tree falls to earth.
And as agerhell has said some energy/mass would be lost as gamma radiation.

yes it does depend on their mass but my question is about spacetime fabric not about them or their mass/energy.

Are you asking a question or answering it?
 

1. What exactly is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape. This is due to the immense mass of the black hole being compressed into a tiny space, creating a strong gravitational field.

2. Can black holes collide with each other?

Yes, black holes can collide with each other. When two black holes come close enough, their gravitational pull will cause them to merge into a single, larger black hole.

3. What would happen when black holes collide?

When black holes collide, a tremendous amount of energy is released in the form of gravitational waves. These waves ripple through space, causing distortions in the fabric of space-time. The collision also results in the formation of a larger, more massive black hole.

4. How do scientists detect the collision of black holes?

Scientists use specialized detectors called interferometers to detect the gravitational waves produced by the collision of black holes. These detectors measure tiny changes in the length of space caused by the passing gravitational waves.

5. Is there any danger to Earth if two black holes were to collide?

No, there is no danger to Earth if two black holes were to collide. The nearest known black hole is thousands of light-years away, and even if it were to collide with another black hole, the resulting gravitational waves would have a negligible effect on Earth.
