Hi there. I just have a question about black holes.
Would a black hole be able to suck-in another black hole?

Unless I missed something somewhere along the line, I believe that the total mass of the universe would be the defining limit. That's essentially the thinking behind the 'Big Crunch' proposal, isn't it? If the limit were lower, such a thing would never have been suggested in the first place.Phobos said:No known upper mass limit for a black hole.
Phobos said:Yes, 2 (or more) black holes can combine into 1 larger black hole. IIRC, the new black hole has slightly less mass than the sum of the 2 black holes that formed it due to energy loss through gravitational waves.
No known upper mass limit for a black hole.
No, Phobos is correct.ray b said:I thought from reading posts here that
there is a gain in total mass
from relitiveistic effects of the high speeds reached
as the two BH sprial into each other at near light speeds

Good point... but it would still be a swell name for a candy bar.Phobos said:Ok, the total available mass in the universe is an upper limit.
But a black hole is an object set within spacetime whereas a Big Crunch would consume all of spacetime as well.
A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. It is formed when a massive star dies and collapses on itself.
Yes, it is possible for a black hole to "suck in" another black hole. This phenomenon is known as a black hole merger, and it occurs when two black holes are in close proximity to each other and their gravitational forces cause them to orbit and eventually merge into one larger black hole.
When two black holes merge, the resulting black hole would have a greater mass and a larger event horizon. The event horizon is the point of no return for anything that enters a black hole. The merger would also release a tremendous amount of energy in the form of gravitational waves.
No, it is not possible for a black hole to completely consume another black hole. When two black holes merge, they form a larger black hole, but the total amount of mass is conserved. Some of the mass is converted into energy and released as gravitational waves, but the majority of the mass remains in the new black hole.
No, a black hole merger would not pose a threat to Earth. The closest known black hole to Earth is about 1,600 light-years away, and even if two black holes were to merge, the resulting gravitational waves would have a very small impact on Earth. Additionally, the existence of black holes in our universe is necessary for maintaining the stability and structure of galaxies.
