what will happen if 2 blackholes collide?

Answer 1

one black hole, (bigger of course)!

Answer 2

I found this at my observatory I work at in the files to answer your question ..

they collide and become one bigger black hole. (A black hole is an object so collapsed and, consequently, with such a large gravity field that its escape velocity exceeds the speed of light.) Black holes lurk in the hearts of many galaxies. When two such galaxies merge, current theory predicts that the two black holes will sink toward the center like stones in swirling water and form a binary pair (circling each other like double stars). However, we don't see this. Instead, recently we found direct evidence the black holes actually coalesce, says astronomer David Merritt of Rutgers University in New Brunswick, New Jersey.

In August 2002, Merritt and Ronald D. Ekers used existing pictures of colliding black holes taken with the Very Large Array of the National Radio Astronomy Observatory at Socorro, New Mexico. The jets seen in the inset of the figure are the smoking gun. Jets orient parallel to the spin axis of the black hole. Sometimes the jets flip.

"The jets initially pointed to the 10 o'clock and 4 o'clock directions. They now point to 8 o'clock and 2 o'clock," say Merritt and Ekers. That happens when the black hole suddenly realigns itself. The only thing big and massive enough to realign a black hole is another black hole. The two merged.

Even a small black hole can significantly influence how another black hole orients. The little guy can realign one up to five times more massive.

How such a cosmic crash happens isn't well understood. Merritt believes that, as the distance between two black holes shrinks to solar-system size, the holes radiate gravity waves and this causes their mechanical energy to decrease. This brings them still closer and they rotate around each other faster and faster as they close. Eventually they collide, sending an incredible burst of gravity waves radiating into space. Astronomers estimate such a demolition derby happens about once a year someplace in the Universe.

Gravity waves are extremely weak wavelike disturbances that Einstein predicted. Massive bodies produce them whenever the mass accelerates or is disturbed. Gravity waves are ripples in space-time and travel at near light speed.

Answer 3

There are no blackholes they just name a blackhole what they ignore about,, blackholes are the dark side of our universe which they still dont have a clue about,, maybe it is something which our means to observe doesnt allow us to see

Answer 4

Black hole simply means an object with infinite gravitataional force. As we now in mathematics when we add two infinites result is again infinite. So, nothing will happen to their gravitational force, the thing for which they are famous. But mass will probably increase.

Answer 5

The collisions ought to reason gravitational waves to ripple throughout area. except that, the newformed black hollow ought to have a mass equivalent to the sum of the 1000's of the black holes that collided.

Answer 6

i'm going to say colliding is something different than merging or one consuming the other. a true collision might cause both to die--BUT if either dies something MUCH worse might happen

Answer 7

i suppose they would explode because a blackhole is formed when a star or constilation explodes.

Answer 8

they will merge.

this is of course independent of size. As you may know, black holes can be as small as the tip of a needle, or as large as a galaxy.

a

Answer 9

Their gravitational pulls would probably combine, creating a super black hole. Either that, or they would cancel each other out.

Answer 10

HA HA HA I know what I would like to give as an answer.

Answer 11

scientist theroize that they form a super black hole, like the one in the middle of our galaxy
