Shame on me, you are right! Supposing a black hole 1/1000 of Earth
mass, the relativistic traveler would have to follow an orbit with
radius in the order of micrometers around the thing. Ridiculously
unsuited for a human-sized object. Next time I promise I will make my
back-of-the-envelope calculations before suggesting outlandish scifi
stuff. :)
