do black holes repel?

Question

we all no that like charges repel
therefore if there are 2 black holes which are both either primarily made of matter or anti matter....will they repel

Answer 1

No, you got a few things confused.
Gravity has no charge, and matter and antimatter anihilate each other because they have opposite electrical charges, like the electron and the postiron. Both have positive mass, and both will be affecting and be affected by gravity in the exact same way, the only difference is that the electron has a negative charge and the positron a positive one.
A black hole made of matter and a black hole made of antimatter will attract each other gravitationally just like two normal matter black holes do.
If two black holes of matter were to repel each other, how would you account for you being attracted to the earth? Both the planet and you are made of matter, yet do you repel one another?

Answer 2

Gravity Assist or Gravitational Slingshot There is a phenomenom such that you can exchange net momentum from one body of mass to another when their paths intersect in certain ways. Many spacecraft are launched into the outer solar system using this method. They may be gravity assisted with Mercury, Venus, Earth, our moon, then Mars many times before being sent on a path to the outer reaches of our solar system. It takes a long time but requires minimal fuel. I'm guessing that a cluster of black holes is unstable and as such will gravity assist each other away. They do not merge because they are not travelling towards each other. For them to merge they would have to be within their respective event horizons. The space in the cluster is much much larger than the black holes themselves. It may be comparable to expecting a marble in the U.S. to merge with a marble in China. Their gravity is enough to influence each other but not so much to actually combine them.

Answer 3

Is it conceivable that two black holes could have such a large electric charge, both negative, that they would repel each other?

Maybe, just maybe -- if they were both made from electrons, which are very light for the charge they carry. But I don't think that in the entire universe, there are or ever will be such black holes.

Answer 4

No, there is, right now at the center of the Milky Way, one or more Super Massive Black Holes that are colliding. They just create a larger black whole. They do not repel each other.

Answer 5

NO..because the primary force related to a black hole is not electrostatic force (which causes repulsive or attractive forces depending on the type of charges) but gravitational force which is always attractive in nature irrespective of charge. This is so because considering the immense masses of the black holes, the gravitational force supersedes the electrostatic force by a much greater amount. Hence they will always attract each other.

Answer 6

Black holes attract each other and all other matter.

There's no antigravity. Matter and anti-matter both attract using the gravitational force. The difference between matter and antimatter is to do with electric charge, not gravity.

Answer 7

No, they would not repel each other. They attract matter due to incredible gravitational forces. Two black holes would attract each other and eventually become one.

Answer 8

Nope. If a black hole made of matter collided with a black hole made of antimatter they would anihilate each other.

Answer 9

I would expect them to attract each other in the same way that two large masses such as the sun and earth attract

Answer 10

If your theory then there would be a gravity that repels. I don't think so gravity only pulls all things.
