I've only ever bought the first one, got the rest for free. I generally like the gun play idea but my interest always fizzles out due to the 'humor' and getting caught in a too high level well... Level and deciding to give up.
In familiar three-dimensional gravity, the minimum energy of a microscopic black hole is 1016 TeV (equivalent to 1.6 GJ or 444 kWh), which would have to be condensed into a region on the order of the Planck length. This is far beyond the limits of any current technology. It is estimated that to collide two particles to within a distance of a Planck length with currently achievable magnetic field strengths would require a ring accelerator about 1,000 light years in diameter to keep the particles on track.[citation needed]
No that's based on Xenia Onatopp
