This question has been bothering me a bit. I know that neutrinos have super small mass and they interact via the weak force. Since they have a non-zero mass, they should be affected by black holes and their paths should be affected by them.
Suppose we have a neutrino of any flavor traveling directly to the coordinates of the singularity of a black hole… or its cross sectional impact includes the black hole coordinate. Basically, its going straight towards a black hole…
Given that a black hole has so much mass and is so dense, it surely must be able to interact with a neutrino, right?
What are the conditions for neutrinos to get trapped in a black hole, or not?

Like zakk says, the key here is to not just think the black hole's gravity as a force that affects objects based on their mass, rather as a curvature of space-time. In this sense, everything, regardless of mass, is trapped in a black hole because it warps space-time in such a way that the area inside the horizon is essentially cut off from the universe. Light doesn't even escape--not due to the gravitational force, rather because of the way that space and time don't allow it a way out.
