While reality edges uncomfortably towards the "Thrice upon the time"
scenario, estimates made (cosmic range energy, rate and impact upon the
Moon over GYr) seem to imply the probability of something going Badly
Wrong is very low.

It would be very nice to find out whether singularities are really
information sinks -- in a laboratory experiment.
