Could it not be equally true to say it is change brought about by physical processes, such as those designated by the laws of thermodynamics, and that time is simply an arbritrary measure of that change? This would seem particularly appropriate if we are dispensing with the concept of spacetime.

So we can now have virtual partciles which are borrowing energy because they exist for only a described time in an explict waveform and the space domain is of no consequence to them.


How can virtual particles be said to exist hey are if not in space?

There never was nothing.
