Question

If light doesn't have mass why is it affected by black hole

Answer 1

Answer:

Even though photons have no mass, they are still affected by gravity. That's how we can see black holes - by the way they distort the light going near them. The reason nothing can escape a black hole is because within the event horizon, space is curved to the point where all directions are actually pointing inside.
