Space is expanding everywhere and not just around the edges. Space inside the edges has photons flying in it, while this photon travels, space is expanding in all of the photons directions. This would mean that a photon from 5 billion years ago would take longer to get here, and its source is even further away than the speed between us and the source would make it be. What I think about during all this: If space is expanding everywhere, then it is sort of pushing things away from each other, meaning that objects are moved, like domino's everything is moved a bit so that everything has more space in between. Do I have to separate expansion of the universe vs expansion of space?
