A question about light and gravity

you should look further into relativity, it is simply fascinating. These places could help: http://en.wikipedia.org/wiki/Theory_of_relativity or more detailed:http://en.wikipedia.......
A black hole distorts space time in a ridiculous way, creating massive dips like bottomless pits, light inside simply doesn't have the energy to take the path out, as the path out is not a particularly short path through space time.
You are obviously very inquisitive, you should look further into relativity, it is simply fascinating. These places could help: http://en.wikipedia.org/wiki/Theory_of_relativity
or more detailed:
http://en.wikipedia.org/wiki/General_relativity
or read the works of michio kaku, brian cox, brian green, and other science writters

Every star, planet, moon, or any mass floating in space at all has something called an escape velocity. If you are traveling away from the mass at a speed greater than the escape velocity, you will break the gravitational pull of the object and keep floating into space. But if you're traveling slower than the escape velocity, you will eventually slow down and get pulled back into the object.
For a black hole, there is a boundary called the event horizon, inside which the escape velocity is faster than the speed of light. Even though light is massless, it still can't escape because it can't travel faster than the escape velocity. This can happen because the black hole curves the spacetime that the light travels through.

very good question and your observation is not flawed. the thing is light has dual nature. it behaves like a particle as well as a wave hence it has a wave-particle nature. it behaves as a particle sometimes and as a wave sometimes. refraction(bending of light when it passes through changing media) is more a particle phenomenon and diffraction (bending of light around corners of objects) is a wave phenomenon. So even light gets sucked into black holes. makes you wonder how awesome the universe really is, right? beyond our imagination!

well, gravity affects light, is an established fact now.. with observations of path of light during solar eclipse etc..
