Mini Black holes?

Wtf.

HOLE not whole

This sort of thing happens just above the Earth all the time to no ill effect. And you're still not a physicist so stop trying to lecture those who are. Physicists are, by definition, not idiots, especially not the ones who build particle accelerators. If they thought they had any chance of killing themselves, there's no way they would do it.

You're not going to get that by firing hydrogen ions at one another at 80% the speed of light.

Woah, they're really that fast?

You backed that up with no logic. You only assumed. Einstein said his biggest regret was his research on the atomic bombs, which have killed 250,000 people. He said if he could go back in time he would have became a watchmaker. Prove to me this guy won't make a mistake like that. He admitted himself there is a probability of complete destruction.

But einstein didn't blow up himself, nor did he have that direct a relation to the creation fo the Bomb itself.

Prove to me there isn't a chance all of humanity won't get sucked in this Quantum black hole. Which according to that article goes against the law of conservation of energy. If Harold is wrong, the black hole will not decrease in size.

And your not a physicist so stop contradicting him. Are you more right then him, he is entitled to his opinion, such as you.

By the way, isn't that "black holes over us all the time" just speculation? I read little about it, like how the reason they don't effect us is because they're moving really fast. But again, that could be speculation also.

And your not a physicist so stop contradicting him. Are you more right then him, he is entitled to his opinion, such as you.

Everybody is entitled to their opinion, therefore I should stop voicing my opinion? Make sense please.

Neither of us are physicists but the physicists do contradict him and that is the whole point. Gettit?

Lol are you serious? Did you not get the point what I was trying to make? You got on his ass(not on everyone else's that talked about emerging black holes), and stated stuff like he knows "fuck" just because he was giving a response to what he read about, just as you. You also know what? He could be right.

Just because a discovery could be significant to us doesn't mean nothing wrong could happen from too. But.... all I'm really saying though is to not be an asshole,there are plenty of those. You say things to him as if you're only right and hes wrong.

Yes a mini black hole. I think doing more research on black holes in the universe would be appropriate instead of creating our own tear in space time.

The realization that holes could be small prompted Hawking to consider what quantum effects might come into play, and in 1974 he came to his famous conclusion that black holes do not just swallow particles but also spit them out [see "The Quantum Mechanics of Black Holes," by S. W. Hawking; Scientific American, January 1977]. Hawking predicted that a hole radiates thermally like a hot coal, with a temperature inversely proportional to its mass. For a solar-mass hole, the temperature is around a millionth of a kelvin, which is completely negligible in today's universe. But for a black hole of 1012 kilograms, which is about the mass of a mountain, it is 1012 kelvins--hot enough to emit both massless particles, such as photons, and massive ones, such as electrons and positrons.

Because the emission carries off energy, the mass of the hole tends to decrease. So a black hole is highly unstable. As it shrinks, it gets steadily hotter, emitting increasingly energetic particles and shrinking faster and faster. When the hole shrivels to a mass of about 106 kilograms, the game is up: within a second, it explodes with the energy of a million-megaton nuclear bomb. The total time for a black hole to evaporate away is proportional to the cube of its initial mass. For a solar-mass hole, the lifetime is an unobservably long 1064 years. For a 1012-kilogram one, it is 1010 years--about the present age of the universe. Hence, any primordial black holes of this mass would be completing their evaporation and exploding right now. Any smaller ones would have evaporated at an earlier cosmological epoch.

Hawking's work was a tremendous conceptual advance because it linked three previously disparate areas of physics: general relativity, quantum theory and thermodynamics. It was also a step toward a full quantum theory of gravity. Even if primordial black holes never actually formed, thinking about them has led to remarkable physical insights. So it can be useful to study something even if it does not exist.

In particular, the discovery opened up a profound paradox that aims at the heart of why general relativity and quantum mechanics are so hard to reconcile. According to relativity theory, information about what falls into a black hole is forever lost. If the hole evaporates, however, what happens to the information contained within? Hawking suggested that black holes completely evaporate, destroying the information--in contradiction with the tenets of quantum mechanics. Destruction of information conflicts with the law of energy conservation, making this scenario implausible.

One alternative, that black holes leave behind remnants, is equally unpalatable. For these remnants to encode all the information that could have gone into the black hole, they would have to come in an infinite variety of types. The laws of physics predict that the rate of production of a particle is proportional to the number of types of that particle. Therefore, the black hole remnants would be produced at an infinite rate; even such everyday physical processes as turning on a microwave oven would generate them. Nature would be catastrophically unstable. A third possibility is that locality--the notion that events at spatially separated points can influence one another only after light has had time to travel between them--fails. This conundrum challenges theorists to this day [see "Black Hole Computers," by Seth Lloyd and Y. Jack Ng; Scientific American, November 2004].

From O's link. So is this a test against physical law? What if physical law is correct?
