dhw:In other words, if I stopped moving, wouldn't I see the hands of the clock changing, though offering a time relative to where I am positioned? -Of course you would. Einstein's was a thought experiment, nothing really possible, but time slows in proportion to speed.-> dhw: Do these experts mean that if there is no observer, there is no time? Surely not.-Agreed-> dhw: Swenson wrote: "I don't pretend to know how tomorrow can exist simultaneously with today and yesterday. But at the speed of light they actually and rigorously do. Time does not pass." I can see how observers of time can telescope yesterday and today, though I'm not sure about tomorrow. But can you please explain to me how time itself can be telescoped?- It is back to time stops at the speed of light. At that speed you cannot observe the passage of events, which to me is a definition of time.
