Quite right. It may be off topic, but I think that scoring this as flame bait is wrong. Slashdot's IMU must be malfunctioning. The Apollo program was not a financial disaster for the US. Clearly our Russian freind's statement demonstrates very little knowlege about life in the States. And considering that the Soviet Union collapsed due to the economic mismanagement of Socialism and central planning, a Russian lecturing others on economics is more than comical. When you consider that Russia is broke, it's pretty sad. BTW: When is RSA going to start paying for their part of the ISS ? We are still picking up the tab for them. $140 million for Zarya, $160 million for the Service Module, and pretty soon were talking about real money here;)
Even if this collider could create a small black hole it wouldn't be a problem.
All black holes undergo a quantum mechanical equivilant of evaporation. The smaller they are, the quicker they evaporate their contents into the visible universe as radiation. The basic idea behind the theory is quantum tunneling. If you compress something into a very very small volume, and as the volume approaches the Plank scale, the probability that particles trapped (in the classical sense) inside this volume can exist outside it will increase. This happens because the Debroglie wavelength of the particles doesn't change.
Now, in order to create a black hole with the small ammount of matter inside the collider, you would be looking at a Shwartzchild radius in the Plank scale. Somewhere in the order of 10^-30 m. (Maybe someone can check me on this with the approximation R=GM/c^2....this value may be too low).
Anyway, at this scale the black hole would vanish in an incredibly short period of time. Far too short to vacuum cleaner the Earth into a blackhole spacetime.
Large black holes on the other hand evaporate on scales greater than the age of the universe. Something on the order of > 10^100 years.
Bones, do you know what you've done ? Pretty soon they'll want a peice of OUR action !!! Star Trek, "A Peice of the Action"
