@th3j35t3r The insight that best explained black holes for me is that the reason light can't escape them is because the gravity is so powerful that spacetime itself-the fabric THROUGH which light travels-is moving faster than light toward the center mass.Like a fish trying to swim up a waterfall, light cannot outrun the flow of spacetime.

The math of General Relativity breaks down when anything moves faster than light. It is similar to dividing by zero.
