Default Blackholes

I'm not sure if this had been a major issue in the recent past but, I need to raise this matter up. I've read in articles and made several research about blackholes. My findings show that blackholes have the tendency to bend light, take-in matter of no specific mass, or even stretch dimension itself. Is this true? And what more can you say about this?

In my thinking, could there be a probability that if two blackholes collide, they may fuse together and form an even bigger blackhole? Meaning a much powerful gravitational field? what if this comes to be and not only 2 will combine? will the force be massive enough to atleast erase some portions of universal dimensions which according to theory is infinite and empty--not to mention continuously expanding?[/b]

Well as it so happens, I have a couple of blackholes upstairs in my closet, if you guys want I could go see what happens when I mash'em together.

A bigger blackhole, yes.

A more powerful gravitational field? Well, think about that for a minute. Even a small blackhole has a gravitational field strong enough to keep light from escaping if the light is inside its event horizon. Add to this the fact that nothing can exceed the speed of light, and.... I get: Nothing we know of can exceed the gravitational force at the event horizon of a blackhole - not even the g force of a bigger blackhole. Since the speed of light is finite and fixed, so must be the gravitational force at the event horizon of a blackhole... Any blackhole. Of course, we don't know what's going on inside; we can't just look inside, we can't send a probe in and receive any signal back... Figuring out what's going on inside is a major problem and likely to continue to be for some time!

If the gravitational power could be measured, what would we measure it in? It would probably have the same grav. field. Even if it did get stronger, It won't matter. It's not like we are going to be trying to avoid them or anything.

If they collided, you'd have a larger, and stronger gravitational field compared to what you had before. If you could measure the strength of the field at the old event horizion prior to the merging, and thne measure the same point after, you would find a stronger gravitational force.

However, like Cougar said, the Event Horizion would still have a force each to c. The horizion would just be further out.

If you mean what units we would use then gravity is typically measured in meters per second squared.
