No, no and not really. Space doesn't stretch thin like matter does, it's a dimension. It is the room in which things might spread. There is no indication of the force of gravity changing or its effects being the result of anything but mass and the proximity of masses to one another.

Light is both a wave and a particle, but its weirdness does not stop there. It already travels at the speed of light, so if time actually affects it it is already stopped. As a wave it exits in the medium of electromagnetic fields, as a particle it is a massless boson that mediates the electromagnetic force. Time dilation doesn't really affect it, and nor does relative speed: even if you are travelling at the speed of light, all light reaches you and is emitted by you at the speed of light relative to you. And relative to everything else. Don't worry that relativity and quantum physics doesn't compute, your brain genuinely lacks the operating system necessary to run this data.

What gravity does do to light is bend it. Light is affected by gravity so its path is curved by curved space-time. One effect of this is gravitational lensing: some distant stars and other objects appear greatly distorted and even duplicate and multiplied due to the light being bent around galaxies and black holes.

so light is completely unaffected by time dialation? so if time was at a complete stop the light would still be able to move through it? and how do they tell the difference between two objects or one object that has been duplicated with bent light?
