Einstein and Godel speculated that time does not run into the universe as humans experience it. Elementary perception is confirming their preposition. One can observe in the universe only stream of material change. Time as a physical entity into which material change runs can not be observed. Time is what one measures with a clock. With a clock one measures a stream of numerical order of material change that runs into universe. One can observe time only as a stream of numerical order of material change. Space-time does not exist as a physical reality, it exists only as a mathematical model, into which one describes stream of material change that runs into universe.
