Apparently, there could be a way for our own particle colliders to create very transient black holes, if some things about the universe are true (as far as I understand, those have to do with the number of dimensions necessary for a micro black hole to be possible). It seems like good research: you prove they are possible and understand them better, and maybe prove other spatial dimensions along the way, or you can't make the current prediction model work and you look for an alternative.
Of course, I know nothing about how hard it is to conduct such experiments and to come up with them. I may be being foolish.
Note that I am talking about experimentation, not theory: is it possible to conduct a series of experiments culminating in one that would say something about micro black holes? I believe we have nothing to lose no matter what's the conclusion. Experimental data is the most valued form of data, if one can say I've been reasonably well taught.
