Post Liquid Black Holes?

Hi everyone!! :-)

I had a strange dream last night that made me wonder about black holes. I dreamt that I was pouring some pop out of a 2-liter bottle, but instead of being pop it was liquid black hole! It was cool because it sucked stuff into it as it oozed around.

I was wondering if scientists had discovered any liquid black holes, or if they had tried to make any. If they haven't made any, do you think they could liquefy some of our black holes in the lab or do we have the technology?

I was thinking about a post in my other thread where someone mentioned that there were more than 4 dimensions. I thought that was pretty cool! So that's why I think I had this dream. I think maybe one of my Guides was showing me how we could maybe get to these other dimensions. I think if we could make some liquid black hole and then pour it into these other dimensions then they would get sucked into our dimension. This would give us extra room and maybe alot of other stuff. Have scientists ever worked on this before??

I tried looking for answers on the Internet today, but I couldn't find anything about this subject. So I figured I would ask you guys. I would really appreciate your feedback.

Thanks! :-)

A "black hole" is an object so dense that not even light can escape. There are none on Earth or in the immediate neighborhood.

It's a good thing, too. As far as we know, a star must be about 2 times the mass of the sun to have enough gravity to condense into a black hole when it runs out of nuclear-fusionable fuel and "goes out". Any black hole within our solar system would be a serious threat to the existence of the Earth.

I'm not at all sure what you're referring to, but it's not a black hole, as far as I can tell. At least, not as astronomers use the term.

Cheers,

Michael

Hi CubicGate,

I've heard ideas about black holes as gates to other dimensions, but only in science fiction stories are they taken seriously (as far as I know). From what I recall of black holes from the last reading I did about them, they're so dense they would crush anyone or anything going through them.

-Perchance.

Cubicgate:

An interesting dream...
Perhaps you could ask your "guide" what is all really signifies...

Be seeing you...

CG,

Your question is meaningless.

Blackholes don't exist as a solid/liquid/gas, they exist as an object that warps spacetime in such a way as that all points lead back into itself.

As to extra dimensions, that is unproven though a common viewpoint at the present.
And "dimension" itself is hardly a straightforward term and is subject to debate as to meaning.

Back to your mainpoint, you cannot clasify a blackhole as to having a state as you describe.
Hawking writes about black holes more then most and some of his published work would serve some good as an introduction to the topic.

Yes! Well, sort of. They're called "dumb holes", and can be thought of as the sonic analogue of black holes. When the velocity of a fluid exceeds the velocity of sound at some closed surface, then a "sonic horizon" is formed by that surface. Learn more by reading this paper:

well, modern theorists suggest that the intense gravitational effects of blackholes can essentially 'rip' the fabric of space-time near them and thus cause the creation of wormholes (or at least tiny microscopic ones which could theoretically be enlarged and used)

Maybe you had that dream because you read about James Randi. He has, after all, sucked away countless hopes of psychic ability for decades now with his tests, debunking, and generally black mood. (I mean black as in cynical.)

I'd be careful hanging out around here- the lure of scepticism might suck you in also.

Well, if you've read the likes of Hawking, Kip Thorne, and other prominent physicists, then you'd know that the general consensus now is that using black holes or wormholes to travel through space-time is not possible. Many seem to think now that the act of an object entering a wormhole would cause it to become unstable (or more unstable) and collapse.

And yes, black holes are not really classified as solid/liquid/gas. The theory is that the matter of a collapsing star has condensed to a point singularity ... mathematically, a point doesn't even occupy any real physical space. I remember reading about the possibility of creating a "mini-black hole" in a lab, but how do you contain it, or prevent it from growing?
