Re: Question about how Hubble can see objects from soon after the Big

But if the space-time manifold is expanding at faster than the speed of light, then we shouldn't be able to see the rest of the universe outside of our galactic cluster at all.

Because the photons emitted from those light sources would end up acting like photons trying to escape from a black hole. Wouldn't they?

That's why I'm confused.

These distant objects are either moving away from us at less than / equal to the speed of light, or more than the speed of light. If it's the former, then the light should have passed our location already. If it's the latter, the light should never reach us and the universe should be a sort of reverse event horizon surrounding us in every direction.

Light that is 13 billion odd years old must have been 13 billion light years away from us when it was emitted, if c is a constant. Right?
