I'm sorry if this has been asked before here - having some trouble with the search engine through our company proxy. The universe is expanding, which means that space is expanding between objects in the universe. To me this means that a journey between here and a red shifted galaxy (if possible) would actually take longer because the distance between us and the other galaxy is increasing, kind of like catching up to the back of a moving train. So if I have this view wrong then my next question may not matter (but if I have it wrong someone please correct me). Space is spacetime. So to me if space (distance) is expanding, doesn't that mean that time is somehow expanding with it? Distance can be measured spatially but how could we measure the increase in time due to expanding spacetime? Also, IF (notice the capital IF) one were able to stand outside of spacetime, what is the speed of the expansion of the universe from that vantage point?
