Black holes, What happens if... Options

What happens if two black holes "collide"? I'm just trying to figure this out about black holes. Are they stationairy or do they traverse with the rest of the galaxy? Obviously the big one in the core of our galaxy isn't moving around in our galaxy. But it could be revolving around some universal core. The pupil of the eye of god so to speak.

But if two black holes were close enough, that any other form of matter would be sucked in, would the two just combine, pull each other apart? Or would the "bigger" one win like an arm wrestle? Or would they cause some strange phenomenom we'd probably hope never happens near us? Like an explosion of forces? Now I know we've never seen two black holes do this but would anybody care to share their thoughts?

Good general introduction.

And the answer to your question...

"The evolution of the collision of two equal mass black holes was computed using a Cray C-90 supercomputer at the Pittsburgh Supercomputing Center and Cray Y-MP at NCSA. The black holes start initially at rest, and accelerate towards each other as a result of their mutual attraction due to gravity. As the holes collide, a large, distorted black hole is formed, which vibrates at its characteristic frequency. The final oscillating hole emits gravitational waves at this frequency as it settles down to its quiet, spherical state."

"If two black holes collide, they will merge to form a bigger black
hole. Two blackholes may exist within each other's gravitational field without
anything special happening. They have to come very close to each other for the
black hole effects to become apparent, and then they'll merge!"

Aint science fun (IMG:style_emoticons/default/smile.gif)

wow now thats something I never even thought about a black hole within a black hole! I wonder how this would affect distortions of space and time. Perplexing.

I think that the only desturbance would be within its sphere of influence, which I dought would be great, I'm sure it would have a really weak field of influence even nearest to it, but dont' get in there lol.

if that made anysense

I think what would happen is simply once the corse reach eachother they combine. So the real question may be do blacks remain stationairy? Do they move? And are they all actually moving to the core of the galaxy?

I dont think its even possible. If you think about it, black holes dont move. They suck in the area around them. Everything. The darkness, the light, the starts, the space. So essentally, when it runs out of stuff to suck in, it will tear the very fabric of exhistance.

If one was to, supposedly, come into contact with another, then they could probably turn the universe inside out.

(This is ironic because I was thinking the same thing today in Physical Science Class.)

It is interesting to ponder. I don't think any phenomenon is capable of destroying the universe. The universe seems geared for some sort of lasting stability. Even if certain areas of it are distorted by black holes. But my reasoning behind moving black holes under the notion that at the center of our galaxy, and presumably all other galaxies, is a super massive black hole. This black hole consumes everything and is theoretically the cause of galactic rotation. So I wonder if black holes caused by dying stars remain stationary or rotate with the rest of the galaxy as well. If the they do move they can theoretically come into contact with one and other. Now when a black hole consumes mass its added to its own casuing the black hole to grow, theoretically as we can't just fly by one and throw giant rocks at it to see if it grows. This idea is supported by the program I saw about super massive black holes. This program talked about how these monsters are active and inactive... yeah almost like it can choose when it wants to consume the galaxy. Of course when its inactive its still potentially dangerous its just not actively consuming matter around it. But when it is active the program I watched said that the super massive black holes seemed to be larger, comparatively so with other black holes in other galaxies.

So I think that if two black holes came into contact with one and other their masses would either destabilize eachother resulting in a super nova or simply merge into one larger black hole... But who's to say merging black holes wouldn't cause a super nova anyways? Possibly the cause of our galaxy... possibly the cause of the big bang creating the universe as we know it. These masses so huge and incomprehensibly dense kinda merger with one and other like bubbles in the ocean. Eventually something causes these masses to burst or release energy/matter (perhaps as a result of the merger) resulting in galaxies, stars and planets. It may take eons of such a big bang to actually run its course but the universe perhaps undulates like the oceans on earth. Energy and matter coaless and bong eachother and eventually come into conflict resulting in a no win situation *boom* the universe is born. Fascinating stuff. So the big question is just how vast is out universe? If we point to the center of the universe as ground zero for the big bang and quasars are the boundries of known existance then why can't there be other ground zeros else where?

And all this from pondering about black holes... fascinating stuff!

When mass is concentrated to what we might call 'gravitic saturation point' gravity becomes a repulsing force rather than an attracting force.

Go see for yourself. Focus on the center of the universe, then expand yourself to see it from far away, then shift intention backwards to the last big bounce. It's really quite fascinating.
