I know, this remark doesn't belong in programming, but I want to respond anyway.
I have wondered the same thing about the statement that light can't escape a black hole because the acceleration due to gravitational attraction exceeds the speed of light. Seems like comparing speed and acceleration is apple and oranges too. Maybe light can't escape, but that's not why.
