Will Strehl What if two black holes approx. the same size colided good question... um, well, fisrt of all, they would both have to be a double star. Second of all, they would both need to become a black hole at the same time... whichever has the larger density would pull in the other black hole... ^_^ I hope the is enough, and that is just my hypothesis... cool

They would combine to form a larger black hole.

might it be possible that they might link and form a gateway or something simmilar dependingon where black holes go like maby an interdimentional (sp) gateway

Black holes aren't moving, so there's no way that they would collide once they are already black holes. Like RCinderGirl1 said if they were to collide the stars would have to be relatively close to each other, however, if the stars are relatively close to each other then they probably would be part of a twin star system which, once both stars reach the supernova stage and if they were massive enough to form a black hole, then they'd probably collide toegether to form a black hole. Though I am not sure about this, I should like to know what someone with more of an astrophysics background thinks about this. I haven't taken astrophysics most that I've said here is a hypothesis and a hand-waving kind of argument.

Will Strehl might it be possible that they might link and form a gateway or something simmilar dependingon where black holes go like maby an interdimentional (sp) gateway So, just wondeing, if it did make an interdiminsional Gateway how would that work? I mean both have such a large gravity that they pull everything including light into it so there would still be no chance to escape out of it. I also don't know enough about this to actually speak as though I do. So what if two neutro stars collided, since they are still mass would something else happen? Since this topic also talks about entropy I was wondering about something that I would wish to bring up. So I have been a firm disbeliever in evolution for quite awhile and one of my main backing points was the second law of thermodynamics, Entropy. Things go from Order -> Chaos. But then my arguement was 'refuted' by the idea that things can have a seemingly chaos -> order function (the idea of evolution) but somehow in the long run it turns out that it is still going downhill (order -> Chaos.) If someone here believes what this person talked to me about, would you mind explaining how that works?

This isn't really the place to discuss evolution/creationism. If you must, I would reccommend the main page as a better place to post your questions. In the meantime, let me direct you to talkorigins. If you ever think you have an argument against evolution, check talkorigins, and I'd be willing to bet that they have the argument as well as a detailed scientific explanation of why it's wrong. Also, regarding the second law of thermodynamics argument, it mainly relies on a misapprehension about the second law. The second law says something like Quote: There is no process that, operating in a cycle, produces no other effect than the subtraction of a positive amount of heat from a reservoir and the production of an equal amount of work. As you can tell, there is nothing about evolution in there. However, if a creationist were to 'rephrase' the second law as "entropy always decreases", and assuming that an evolved form has a greater entropy than the previous form, and assuming that the total other entropy in the universe remains constant, then evolution is impossible. Of course, so are pumps, snowflakes, tying your shoelaces and creationism. As you can tell, something in there isn't quite right.

If someone here believes what this person talked to me about, would you mind explaining how that works? Heat. In the long run, your body sirs up more air, heats more molecules and breaks more bonds to make up for the entropy it "defys" Like a refridgerator. Refridgerators make more heat then they "absorb", the only reason the device is useful is that it produces entropy in the outside environment to lower it to a lesser degree within.

Ahh, that makes a lot more sense. I guess I was thinking too narrowly and linear.
Still what would happen if two neutron stars collided, would their energy backfire and create a sort of supernova then form one black hole?

I haven't taken astrophysics most that I've said here is a hypothesis and a hand-waving kind of argument. Two Black holes could be moving relative to one another. They could just stumble across one another. Mathematical models describe the collisions of supermassibe black holes when galaxies come together. And heh, you wouldn't want to be anywhere nearby because according to simulations, they'd release more energy than the light from all the stars in the universe combined. We're talking ridiculous amounts of energy here.

First off, black holes, like everything else, CAN move. They are affected by gravitational forces (albeit in a very minor way owing to their high mass and absolute density), therefore they can move.
From what I understand of the subject, a theorized merger of 2 black holes would generate one black hole with roughly the mass of both. The way this works is that the black holes themselve cannot be treated as solid objects anymore. The event horizon is just a mathmatical idea, not an object in any way, shape, or form. The only mass in a black hole is in the absolute center. in the form of a singularity that has infinite density.
Since mass is already condensed infinitely at the center of the black hole, two black holes colliding would simply merge into a more massive singularity. In doing so, they would release what are called 'gravitational waves', distortions in space-time generated by extreme fluctuations in gravitational field that are roughly equivalent to electromagnetic radiation. It's the gravitational equivalent of a flash of light.
As for merging neutron stars, they would release an incredibly bright flash of gamma and X-ray radiation before (most likely) becoming a black hole.

Would black holes be really high entropy or really low entropy? eek
