I'm sure infinity must exist in a black hole simply because light can't escape.

Light itself also experiences infinity. It experiences infinite time dilation and infinite space contraction, thus, from the photon's perspective, the universe is a 2d plane, and the photon is motionless [citation needed].

But we see a 3d, or 4d if you count time, world, and we can see the light moves along a trajectory.

You won't escape Earth. Is Earth's grip on you infinite or simply over some threshold/limit?

Also, to the idea of the photon and it's infinite experience of time - you're literally saying that

a PHOTON

EXPERIENCES

INFINITE

TIME

and that this idea passes effortlessly through your mind with no problems.

...and that this idea passes effortlessly through your mind with no problems.

I guess I don't demand a full understanding of a concept in order for me to accept it as fact.

Light exists. I can see that. It travels at light speed, by definition. Our mathematical understanding of time dilation implies that at light speed, time dilation and space contraction are infinite. I'm not having a problem here. The only thing I might think is that maybe light speed is another theoretical concept, that actually the photon always travels at <c due to gravitational influences, and as such infinity is never actually attained.

But I don't have problems with accepting that light can experience time in a way that I can't understand.

I don't have problems with ideas when I need to use them.

But when I'm left to my dreams, I like thinking about thinking about thinking.
