Black holes can have an electric charge, right?

So if you have, for example, a negatively charged black hole and you throw a positively charged object in there, the charge of the black hole should become less negative, right?

But doesn't that imply some form of information is escaping from it?

Discuss.
 
Don't like black holes personally. I'm not racist (OLOLOL), but I prefer white women.

As for black holes in space, I have no idea, however wikipedia says they're very unlikely to be produced in nature. And we all know wikipedia knows best.

Yes, but it doesn't carry any information.

An electrical charge doesn't have to carry any information either.

You can't communicate with a black hole through the internet :p

Saw a program on this the other day and I came to the conclusion that it's not worth thinking about too deeply
 
It's worth thinking about deeply because it's a curiosity. Back in the dark ages, I suppose they thought that anomalies which contradicted the "sun and planets go round the earth" thing weren't worth thinking about too deeply. The michelson-morely experiment: light goes the same speed from any frame of reference. Agh too difficult, it's not worth thinking about.

What I said was tongue in cheek

But tbh there's already lots of fact and theory on the subject , I doubt anyone who spends there time on forums is going to come up with anything better than Hawking, etc - no offence to anyone :p

But I don't see what you're trying to get at? An electrical charge doesn't necessarily carry information. You could put it into some sort of decoder and get some gibberish, or perhaps even legible information, but that doesn't mean anything.

I was under the impression that it was fairly widely accpted now that there is a super massive black hole at the centre of every galaxy, the black hole being what is holding the galaxy together.

Liked that song by muse, actually, I think I will listen to it now.

well its failing, we galaxies are still shooting away from each other... :rolleyes:

Yes, eventually we will be dragged back, and there will be a big crunch, quickly followed by another big bang. Apparently we're on the 6th cycle of this, however the hell anyone is supposed to know :confused: Still, that will be in trillion's of years, by which time a "year" won't mean anything to anyone because our Sun will have died long ago, so our "year" will be of reference to a period of time that is no longer in use :rolleyes:
 
Dark matter is keeping our galaxy together. Though it's unknown exactly what it is. Dark energy is what is pushing galaxies away from us and is accelerating the rate of expansion. The Big crunch is just a theory of many on how the universe will end. There is also the big rip and then the death of all stars meaning no light/big empty space.
 
I find space very intresting but i dont know much about it. Could anyone recommend any decent books/webpages?
