I'm open to "extreme possibilities", as they used to say on "The X-files", but no matter WHAT is or isn't happening in the universe, time is nothing more than our perception of it. We can TRY to quantify it and other things with it, but that is just our very new, primate brains, a mere 9 million years out of the African plains, trying to look and sound "smart". I prefer John Lennon's approach, in his song: "I'm just sittin' here watching the wheels go round and round." That, basically, is all humans are really doing.
