That 22ug blackhole is the lightest one and thus the one that decays the fatest.That blackhole would decay in 10^-44s. But to create one, you'd have the mass-energy of 10^19 protons in 10^-35metes, that is, a radius 10^20 smaller than 1 proton. That's quite a small cross section. So, the expanse of energy to create one instead of a huge shower of particles is quite huge, since a formation of one should be quite unlikely. I am not aware how that would be done...
But, the Black Hole Stewart mostly refers to (when he is not talking about the 22ug one) is a multi dimensional one, which would have a mass of 1-8TeV. 'Only' 1-8 thousand proton mass. Since it is an entity that does not belong in GR or follows the usual quantum field theories, its properties are quite unexplored. But, the creation of one would still require a huge number of fail attempts. And even if a certain mechanism to create one, figuring out how it would interact with usual matter is a huge unknown... 2012/8/21 Abd ul-Rahman Lomax <[email protected]> > This back to the 22 microgram BH.
