Linearity
We experience time as a continuous and scalar scale, by means of which we may assign a sequence to any two events and a duration to the interval between them. This duration is additive: the duration between events A and B and the duration between events B and C is equal to the duration between A and C.
Time and causality
We observe that a quantum event which affects particles that are separated by spatial distance nevertheless affects them all at the same time.
We observe that it is always possible to understand causal relationships between events in terms of the first event in quantum time causing the subsequent event in quantum time. We observe that quantum time has an arrow, things do not go back in quantum time. What’s past is past. Only the future can be affected by actions in the present. This is despite the fact that almost all the equations of physics work just as well in the reverse time direction as the forward one. Excluding, of course, quantum processes in which space quanta or particles are added to the universe, and any processes which add disorder to the universe.
Experienced time
We observe that experienced time may run slower than quantum time, sometimes to the point of standing still. This in no way prevents objects for which experienced time has stopped from participating in sets of quantum events that coincide in quantum time. We observe that experienced time is intimately bound up with space, especially the gravitational structure that it appears to have. In General Relativity, objects move with the speed of light in space-time, with those that we perceive as being stationary moving entirely in time, and those that we perceive to be moving at the speed of light moving entirely in space and not at all in time.
We observe that natural law does not seem to change with the passing of quantum time. This is a sub-phenomenon, which is discussed separately in the lemma unchanging phenomena-exist.
Explanations
For mainstream science, time is essentially a mystery. There is no explanation which can be assigned an Occam score. One can only conjecture that one day someone will come with an explanation for it, including how it manages to affect everything that we observe to be subject to change. At best, that is a complex gap, with an Occam score of 0300, relative to the Big Bang theory .
The QO explanation of time is rather straightforward: it is the dimension in which quanta are subject to change, and it came into existence along with the first quantum. As such, it introduces nothing new beyond the QO concept of genesis, and has an Occam score of 0000 relative to that concept.
It goes without saying that the QO explanation of time is to be preferred.
