So here is something I've been wondering. One of the biggest things which sunk infinite universe theory was Olbers paradox, which in a nut shell states that if the universe was infinite, then there would be no dark space in the night sky since in every direction would be a star, but reading into general relativity one has to acknowledge that it is actually possible to apply infinity into calculations (as this explains black holes), which removes infinity as being an illogical number, and due to black holes it is known that light is actually effected by gravity. With this one could assume that at a certain distance light emitted by a star would be shifted due to moving such a vast distance, while being pulled by gravity transferred on to it by dark matter.

The reason we don't see an infinitely bright sky from infinite stars around us is because those stars have not been around us forever, they have only been around us since the Big Bang, which is not enough time for their light to reach us. The reason we don't see an infinitely bright sky from the energy of the dense universe of the Big Bang is because that light has been so redshifted by the expansion that it is only visible with microwave detection. So the "paradox" means that the universe cannot be static, it has nothing to do with it being infinite.
Thanks, that's not really what I was asking, but that's my fault for not articulating the question very well.
>Let me try it another way
Let's say that if we where on a fixed point, would it be possible for a fixed light emitting object to be so far away, that the light does not reach us, due to gravity slowly altering it's course?
I thought that the universe was infinite but at a certain distance it expands faster than the speed of light, making the photons from those stars never reach us
Yes of course. A black hole blocks us from seeing everything behind it by pulling the light from those objects into itself.
Yes, but that only explains why we won't be able to see them in the future, not now. Billions of years from now we will not be able to see many of the astronomical objects we see today.
thats pretty interesting actually, There would be infinite gravity in every direction cancelling that effect as well right?
I know that part, what I'm wondering is if there is a cut off point at which it requires so much gravity to shift a photons flight path, or if it's that it takes a massive amount of gravity to shift a photons path enough to become observable.
>infinite gravity
Huh?
