Mmm, okay, so for example...

Say, 10 billion years ago, a supergiant star went supernova in the halo of a young galaxy and sends photons that the Hubble Space Telescope focuses and images today.

But in 10 billion years, the universe has expanded so that star is actually, I don't know, about 50 billion light years away now. In the beginning, the star and photon are leaving each other at C but as the distance increases the space between them expands. and THAT makes them separate at a distance greater than C. But the image we see is a 10 billion year old image and we have no idea what that star is like in our time, today, at a distance of 50 billion light years.

We know that C is the limit in our accelerators, we push particles to that limit everyday and they will not go faster, just get heavier.

The photons are limited to C but spacetime is not. Spacetime is the medium that photon travels through.

Does that make sense?

And for my sake, please do not increase gravity. I have an hard enough time as it is! Now, if you could lessen gravity without losing the oxygen, I could support that!
