These guys are nuts! How can they know they won"t inadvertently create something that can endanger us all?

the age of the universe is well known now there people . . . it is 13.7 billion years old . . . get it right!@

You've obviously watched too many Sci-Fi movies where a black hole forms, then drops through to the earths core and we're all eventually sucked up into it.

If you're afraid of a cascade of decay particles, fair enough, although be warned these events are occurring all the time, as extremely high energy cosmic rays can produce similar decays from collisions here on the earth.....might even smash into your unmentionables. I suggest you invest in a large lead codpiece

Sure, but any subsequent nano black hole formed would be knocked clean through the earth before it would have time to accrue mass. Their black holes might have no relative momentum to the earth.

I know that then you'll say, "Hawking radiation will tend to that." But what if Hawking radiation doesn't really work?

Then you'll say that unless there are higher dimensions, black holes can't form in the LHC anyway. What if they can?

Besides, what if they inadvertently create strange matter or some other weird and dangerous particle we don't yet know about?

Obviously the odds of any real danger are long, but the stakes are extremely high. Wouldn't caution be the better part of common sense here?

The Chandrasekhar limit is the minimum mass (of a white dwarf star) required for a black-hole to possibly form. This is over 1 solar mass and exceedingly unlikely to ever be generated in an earth-bound accelerator.

This is merely a new generation of detectors for one of our most advanced colliders.

Forget the Chandrasekar limit, as singularities can and are as I hypothesise , formed readily by all particulate matter in our universe. They're nothing to be afraid of; our bodies each contain over 10^27 of them.....with no ill affects.

To create a singularity one needs a force, which can be only attractive. Like the gravity. I don't know other forces that have the property.

So we have:
Gravity - Chandrasekhar limit of the minimum mass
EM, weak and strong forces - don't classify as only attractive.

I disagree, all you need is energy.....of any magnitude

All you need is energy.....all you need is energy....all you need is energy, energy...energy is all you need....To be sung to that well known Beatles number.

Our Universe contains tremendous quantity of energy. Is it singularity? No. That means we must have something else that will FORCE that energy to get together. We need force.

What you actualy need is energy per volume. (above a threshold and a black hole will naturaly form)

Quite right....and as a singularity has no volume, any amount of energy can create one!

....especially if it exists as a trans-dimensional vacuolar envelope.

Please refer to my Spacial Vacuoles model.....just type spacial vacuoles in a google search and you'll hit it (as it's totally unique)

Scientists doing experiments at ultrahigh energy accelerators have been glib about the possiblitiy that mico black holes pose a threat to humanity or to life on Earth. Black holes are gravitational bottomless pits in space-time that suck matter into them and they grow by a never ending process of attracting matter into them selves that can never get out. The added matter adds to the black hole's gravitiational force accelerating the process ad infinium. In the seventies when a lot of theoretical work on black holes was done, it was believed that a quantum
black hole produced on Earth would absorb the matter near it and it would fall through the crust of the Earth down through the mohole all the way to the center of the Earth. It would "eat" the matter comprising the Earth with ever greater speed until the entire Earth was consumed by the black hole a few years later as its' weight and gravitiaional force grew exponentially.

In the Eighties and afterward Steven Hawking theorized that black holes would dissapate in a burst of gamma rays that would be produced by materialization of real particles from vitual particles at the black hole's event horizon. Thus quantum scale black holes could be expected to lose weight instead of gaining weight by eating ever greater amounts of matter.

But it is possible that the theory Hawking has propounded might be incompletely worked out and there might be some very serious complications from an experiment to manufacture quantum black holes on Earth. It might be a mistake that costs the life of every human being on Earth if some theoretical calculation was missed. Maybe it is possible that quantum black holes produced in the Large Hadron Collider will absorb more matter than they lose by emitting particles. It may be impossible to know exactly how quantum black holes will behave until they are produced and studied. The consequences of scientific disoveries are often not fully understood for decades after the basic mathematics is developed.

I belive that deliberate production of black holes ought to be banned by international law. Experiments such as those proposed at the Large Hadron Collider should be put off until particle accelerators are built in orbit or on the moon. Einstein is often quoted as saying that a misplaced zero in his cosmologial equation was the biggest mistake of his life. Nobody thought such a mistake could have consequences in the real world. There might be some mistake in Hawking's equations that could be the mistake that destoyed the Earth and all human life. That would be the biggest mistake ever.

Neil,

I'm with you. I recommend that everyone reading this write to their local officials, in protest.

Fear of unknown...
Do you really think that we're able to create energies that aren't normally produced in our Sun? Do you really think that these "ultrahigh energy accelerators" could create black hole? Single particle black hole?
Where are the black holes that our Sun(or any star) produces according your theory. Why our Sun is not destroyed by them?

Because they are created with so much relative momentum that they either fly away into the galaxy's central black hole, or to the outer reaches of the galaxy where it's called, "Dark Matter."
