Does light have Mass?

I am confused. Evrey were I look they say light has no mass. But yet it can be diviated by gravitational pull. They also say that black holes are so dense that light cant even escape. Can someone explain to me how that can happen to something that has no mass?

Space is warped in the presence of matter and the more matter the larger the warp

Don't you see or understand that that is impossible? Space can't be warped? How could it?

Space certainly can and does have structure, everything does. It is just that not everything that is real, can be described by humanity, as humanity does not even know where it came from, nor what it is itself.

Odd, sad, and quite true.

Space isn't nothing.

We can observe the effects matter has on space when we view objects. Even our sun creates a distortion where a star behind the sun is visible because the sun is bending the space near it causing the light behind it to curve around the sun so it is visible to us. Einstein even predicted this possibility and it has been observed many times. Even the ultra deep field photos have gravitation lensing artifacts. Einstein's explanation of gravity is based on the idea that space can curve and bend in the presence of matter.

This is how gravity can effect objects at very long distances. The sun isn't reaching out and tugging on objects. Instead the sun is creating a sort of well these objects are falling into. If the gravity is intense enough the warpage of space is so great that it bends the light's path giving the illusion that light is not traveling in a straight line. It in fact is traveling in a straight line but the space itself is bent and light is just following the curve of space. Like a car down a curvy road. You would assume the car could just travel straight but it is just following the path of the road.
