Q: Which of statement below about black holes is not true?
If you watch someone else fall into a black hole, you will 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.
A spaceship passing near a 10 solar mass black hole is much more likely
to be destroyed than a spaceship passing at the same distance from
the center of a 10 solar mass main-sequence star.
