What if we took 100 alarm clocks that we set to go off every 60 minutes? Starting with the clocks, let 99 people take one clock each and walk away in random directions. After 60 minutes, would they all ring simultaneously? What if there was no human or other life form to hear them - would they still be simultaneous? What if there was no mechanical sound recording equipment to even verify that any sound occurred - would they still not ring at the same universal present? One rings at its location while at the same universal present, the other 99 bells are also ringing. Does simultaneity need verification in order to occur? Like the tree that falls in the forest - it is not the perception of a phenomena that determines whether or not the phenomena occurred.

Einstein seems to imply that simultaneity occurs only if we can verify it through a measurement process. He links the speed of light to time, and uses this equally to conclude that there is no universal present.
