    Have scientists ever tried to create a black hole in a vacuum?

    Where would they get the materials?

    We don't have the technology for that at the moment.

    Are the God particles created in a vacuum?

    They have been theoretically predicted so they could form but they have never been observed, lots of things get predicted and this one is more realistic then time travelling particles.

    the higgs boson particle is of yet unconfirmend people are trying to create it in a particle accelerator

    This is an incredibly stupid colloquialism. The Higgs particle has nothing whatsoever to do with god or gods.

    Anyway, as orcot says, particles such as the Higgs can be created in particle accelerators which are basically vacuum tubes into which you inject some particles (for example the LHC uses protons) and smash them into each other. The reason you need a vacuum tube is because the protons would hit particles in the air causing loss of energy and difficulty identifying the products.

    Bugger! And there I was, planning on naming the next undiscovered particle the buttered-toast-that's-slightly-overdone particle.

    In a new study, scientists have proposed that mini black holes may interact with matter very differently than previously thought. If the proposal is correct, it would mean that the time it would take for a mini black hole to swallow the Earth would be many orders of magnitude longer than the age of the Universe.

    See Link: Mini Black Holes

    In their paper, which is posted at arXiv.org, Aaron P. VanDevender from Halcyon Molecular in Redwood City, California, and J. Pace VanDevender from Sandia National Laboratories in Albuquerque, New Mexico, wanted to find a way to detect the mini black holes that are thought to exist in nature.

    Their calculations suggest that mini black holes may be passing through the Earth on a daily basis, and pose a very minimal threat to the planet.

    On a somewhat related (while we're at it) topic, can we create a black hole weapon that sucks up the enemy's nation and leaves nothing? Turning off the black hole seems to be the challenge- once you created a stable black hole that exists for seconds, that is.

    A very small black hole hitting the earth with a high velocity would not be slowed down much & would pass through without causing much damage.

    There was a SciFi story about a tiny Black Hole found on Mars by the first humans to get there. It was in a signaling device left behind by star travelers from an advanced culture. It was charged and manipulated by electromagnetic effects, creating gravitational waves.

    The humans tinkered with the device & released the Black Hole. Since it had very little initial velocity, it fell toward the center of Mars (highest velocity at the center) & contiinued moving toward the opposite mars surface (slowing due to the Gravitational effects of Mars). It acted somewhat like a yo-yo, gradually eating Mars mass & become larger.

    Mars had to be abandoned, since it would be consumed by the Black Hole. The resulting Black Hole orbited the sun at the distance of the original Mars. It was a potential hazard to any space probe or space ship coming too close.

    I think the scenario described in that story is valid. I would expect the destruction of Mars to start slow, but speed up exponentially.

    The resulting Mars-mass Black hole would be no more dangerous than the original Mars as long as an asteroid or space ship stayed 10,000 or more miles from the Event Horizon (I think this is a high estimate of the danger distance, which depends on the velocity of the asteroid or space ship).

    I would not bet a large amount of money on my opinion, but would risk a bit of cash. In a betting context, I define a large amount of money as more than I can comfortably afford to lose.

    This leads me to believe that matter is destroyed due to the vacuum in which the black hole occurs.

    Why would a vacuum destroy matter?

    So you consider the matter of a black hole to be destroyed matter? Hardly, it's highly compressed, but still matter.

    Despite what some scientists have suggested about the possibility of there being micro black holes, I believe it is pure speculation and that no such thing has ever existed or ever will. The idea of anyone creating a black hole is ludicrous vacuum or no vacuum.

    Agreed. It would be far easier to create a planet or a star. Lets try to create a decent artifical sweetner and then we can move on to creating black holes to vanquish our enemies.:bugeye:

    Super collider.

    I'm not saying they have, but I seriously doubt they haven't TRIED to create a micro black hole in one. I would.

    It would be like buying a top of the line 4,000 dollar gaming computer and using it to watch hulu and post on twitter.

    Well doesn't a black hole only ever occur when a certain amount of matter is compressed to a small enough size? And that size is defined by the mass itself?

    So if that always applies then why can't you just size it up or size it down?

    All they can do is crank up the power and study the results. The only thing they are trying to do is advanced science trying to learn something new. They are not trying to create micro black holes. Like I said before that was nothing more than wild speculation that someone latched onto and sensationalized. After all the thought that the Earth could be destroyed by micro black holes is a real attention grabber and a good example of public gullibility.

    The answer is how the matter gets compressed and how it stays compressed, and that's gravity. Even if it was possible to slam a few protons together and create that level of compression there would be virtually no gravity to maintain that compression. So what would you really have, it would be a new particle maybe, but would it be right to call it a micro black hole. Anything that has a half life in the billionths of a second could never be called a black hole by anybodies definition.

    As far as black holes go there is a minimum size based on the gravity needed to maintain the compression of the matter in a black hole. From that minimum size it can be sized up to some currently unknown size. As to what the minimum size it can be I don't know but I'm sure with a little browsing around I could probably find some pretty good estimates.
