This has got to be of the single hardest concepts to wrap your mind around (if that can be done to infinity) A universe that has a beginning and expands at a finite speed must have an envelope that expands with it and which by definition marks the edge of spacetime.however in looking at the stars because of the finite speed of light we are looking back in time to how the universe was.Since the information brought to us in different forms of electromagnetism are all we have at present to determine what the universe is (was) like it seems there is no way to actually determine if infinity exists.the conceptual difficulty really begins with trying to understand what exactly the universe is expanding into.These are the kinds of questions that pharmaceutical companies make money from the sale of headache medications.Anyone got further insight into this?
