Practical Tips for Black Hole Explorers

Apropos nothing in particular, this fascinating article, which tells you how to maximize your remaining time if you accidentally cross the event horizon of a black hole:

Falling into a black hole is a strange affair. Because the hole’s gravity distorts space-time, a far-off observer watching an object crossing the event horizon sees time for that object appear to slow down — a clock falling into a black hole would appear, from the outside, to tick ever slower. At the horizon itself, time stops, and the object stays frozen there for the remaining lifetime of the Universe.

But this isn’t how things seem to the in-falling object itself. Indeed, if the black hole is big enough, nothing noticeable happens when a spaceship crosses its event horizon — you could stray inside without realizing. Yet once inside, nothing can save you from being crushed by the hole’s gravity sooner or later.

  1. Nice advice, I will try to consider it next time I cross an event horizon (that is, if I should notice it). BTW, why is this excursion categorized under Science and not under Travel?
