When I experienced the 2011 earthquake here in Virginia, that was
my first thought:  That those who warned that the LHC or some other
collider would create a black hole that would swallow up the Earth
were right, and I was about to fall 4000 miles straight down, along
with everyone and everything else on Earth.

It retrospect it's a rather silly idea.  Every day for billions of
years, Earth has been exposed to cosmic rays with far higher energies
than LHC could ever reach.  If planets could so easily collapse,
our solar system would contain a lot fewer planets and a lot more
planetary-mass black holes.  And yes, someone would have noticed
such black holes by now.  Just ask Adams and Le Verrier.
