Detection of black holes at the LHC could indicate parallel universes

Just want to comment on this sidenote. Those many worlds interact with each other through interference. For example instead of saying that a particle went through both slits and interacts with itself, you say that it went through one slit in one world, the other slit in the other world, and that those two worlds interact to produce the probabilities giving rise to the distinct interference pattern. In that simple setting it may seem like an unnecessarily complex way of viewing it. The advantage is that you don't have to hand wave about wavefunction collapse - a process which afaik doesn't actually happen.
That is my understanding anyway, but if I got something wrong I would much appreciate if someone corrected me.
the energy required to produce black holes
in four dimensions would be much larger
(1019 GeV) than the energy that can be
achieved at the LHC (14 TeV).
I have my minimum font size set to 18. Because of that, Firefox renders all four digits at the same size. It also does not superscript the last two digits. I just checked, and it's the same in Safari.
One could expect that, even if minimum font size is set, that the concept of "superscript" would survive, i.e. that the digits "19" would be rendered above the typographic baseline.
One could expect that, but one would be wrong. :)
