Creating a microscopic black hole is tricky, since one needs a reasonable amount of neutronium, but may possibly be achievable by jamming large numbers of atomic nuclei together until they stick. This is left as an exercise to the reader.
I stopped reading at that point. Neutronium is mostly a sciencefiction term. It can, and has, been used to reffer to neutron degenerate matter, but not so great other wise.
Also you don't need "nuetronium". The LHC should do the trick which also means that they have been produced in the upper atmosphere in the past, present, and will continue being produced in the future. I dobut they have the mass of mount everest however.
Also, anti-matter isn't an explosive substance.
[edit] Oh, and for future refference, this should be in the Lounge, not General Discussion.
