never see him (or her) cross the event horizon; you'll only
|| || || || || || || || || ||
see him fade from view as the light he emits or reflects
|| || || || || || || || || || || || ||
becomes more and more redshifted. || || || ||
Although we are not 100% certain that black holes exist,
|| || || || || || || || || ||
we have strong observational evidence in favor of their
|| || || || || || || || ||
existence.
If you fell into a black hole, you would experience time to
|| || || || || || || || || || || ||
be running normally as you plunged rapidly across the
|| || || || || || || || ||
event horizon. ||
