Black hole + black hole = what?

Okay this is very simple to answer,one "Black hole" is going about it`s own business and along comes another that is going to collide with the other one.The two collide in a magnificent dance so to speak and eventually the two become one only more massive,but no more dense as the black hole is already infinitely dense.

There was actually an experiment. When two black holes come near each other they enter a 'waltz'.Laws of physics wont allow one of them to suck another one in. They would start circling each other in a pattern till the they meet. Since black holes are singularities( a point in space where gravity is so much that not even light can escape) they would most likely merge with each other silently. Since a black hole is just matter crushed into a tiny space, then they would just collide and make a bigger black hole However, it is possible that when they get near enough and the event horizons meet there will be so much energy that it'll bend/ warp the space in between, creating a type of wormhole(small portals, possible smaller than atoms, that can cut space traveling time short).

Yes, its possible.

When 2 black holes merge, they form a black hole with the combined mass of the 2.

Black Holes do not exist. No Probe or spacecraft has ever been near one and no person on planet Earth has ever seen one up close. It's the most ridiculous theory known and dumb sheeple actually believe what they have been told by scientists and astronomers that Black Holes exists when in fact they never seen one and all they are doing is verifying their own version of results and data and shoving it in our faces and making want us to believe in this fantasy called black holes.

scientists believe that black holes are literally worm holes to other parts of the universe so if a black hole sucked in another black hole it may cause the sucked in black hole to become the other door of the universe.

A black hole cannot be seen it can be seen with ULTRAVIOLET LIGHTING... scientists have created the theory that we are in a black hole already because of the darkness and never ending to space if there is a never ending and a black hole sucks in everything that means that space is getting bigger every day,,

Black holes come from a Hyper Nova which is a sun bigger than our sun 10x bigger in fact.. when a Hyper Nova has used up all of it's energy after trillions and trillions of years and has nothing to keep it's energy burning it eats all of it's energy until it get's to the core when it get's to the core it has nothing to feed of - what is space matter it is nothing so it get's denser and denser untill it finally sucks everything in ^_^ hehe makes more sense right LOL science is very interesting ^_^ good question by the way LOL

You already have your answer. I read something interesting recently that you might be interested in.

I read that a fairly recent paper claimed that most gold now existing in the Universe was NOT the result of supernova, rather the result of high energy collisions near binary black holes or binary neutron stars (in close orbits). This might also go for elements above Gold in the periodic table, but that is less certain, since the paths of nucleosynthesis can and do take some unexpected twists and turns.

Then it becomes more massive. They're both masses. A star is a mass and if a black hole devours a star it simply becomes more massive. Don't worry, there's nothing that contradicts common sense in this topic regarding black holes, but I'm sure you'd get a pretty big release of energy with quantum fluctuations occurring more frequently as their event horizons meet.

Supermassive black hole. Sagittarius A* is the name of the one at the center of the Milky-way

A black hole with a different angular momentum.

Wouldn't it be interesting if we found two black holes in a tight orbit around each other?
