What makes light not be able to escape a black hole?
Mel asked:
I’ve read over and over again that nothing travels faster than the speed of light. My question is this: if the force of a black hole is so strong that not even light can escape it, then might that mean that whatever “force” in the black hole travels faster than light itself? Forgive me for not fully researching before I ask… I know the answer’s probably just a google away, but it’s always cool to get opinions from real people.

What happens to light passing through even thin clouds of dust?
Joseph P asked:
A) The light that passes though them is blue shifted due to the cloud’s approach.
B) Its motion causes all light to be red shifted as it passes through these clouds.
C) Its motion causes the light of stars beyond to twinkle.
D) It dims and reddens the light of all more distant stars.
E) Even a little can completely block all light, such as the Horsehead Nebula.
