[SOLVED] Isn't space expansion expectable? Since Einstein showed that space and time are in fact entwined as a single entity spacetime, it makes me wonder if it's not just natural that we see space expanding with time. As we examine spacetime forward in time (looking at regions where "the quantity of seconds" is increased -regions where time has expanded-), it may only be natural that we find also that "the quantity of meters" is also increased -space has expanded as well- ???? I know I'm wrong, because I know our physical theories allow scenarios where even when time continues to increase space shrinks, but I'd like someone to explain why the type of entanglement between space and time does not have anything to do with both increasing or decreasing together. And now that we talk about expansion, an even more silly question: Has anybody played with the hypotesis that from a relative perspective, it could be that instead of space expanding, matter and energy could be shrinking into a fixed size space?
