I was thinking about some descriptions or explanations popularized by physicist on television that explain why light cannot escape a black hole and some concepts involving the observable universe, and I came to a conclusion that the observable universe must be seen to be getting smaller.
For starters, it has been said that the reason why light cannot escape a black hole is because the space itself around a black hole is traveling faster than the speed of light. So then the edge of the visable universe has galaxies that are traveling close to the speed of light. Then they do this because the space itself is expanding away from us close to the speed of light, and it has been said that this is okay because it is the space itself that is traveling faster than light. So then I assume that the reason why we cannot see galaxies past the edge of the visable universe is because the space itself is expanding away from us faster than the speed of light. So then what happens when these galaxies traveling away from us close to the speed of light end up traveling away from us faster than the speed of light with the expansion of space? They would no longer be able to be seen in our visable universe. Then since the rate of expansion is increasing, then the distance away from us where galaxies are traveling faster than the speed of light will become closer and closer to us. So then it seems like it would follow natuarally that the observable universe is getting smaller since the distance a galaxy would travel faster than the speed of light would become increasingly closer to us over time.
It seems like a strange concept, but over the past few decades the age of the universe hasn't seemed to get any older. Could this cause our preception of the age of the universe to always appear to be getting younger?
