Closer To Truth – Physics of the Observer
Are events measured by time? Or is time created by sequences of events? Which is more fundamental, events or time?

Yeah but….
The arguments here only provide for local variation in 'measurable process rate' as time, which is of course absolutely fine, but it does not seem to refute an absolute present moment such that although my two clocks may progress at two different rates there is still a possibility of turning them both off "at the same moment" and then bringing them back together to show the average rate that they differed while apart. This sort of experiment may one day be possible using observation/measurement of quantum entangled processes as 'now markers' given the instantaneous nature of the connection.
In fact it seems that the instantaneous nature of quantum entanglement during arbitrary separation in space already tells us that there really is a universal now, albeit perhaps impossible to.
What I am suggesting is that what is happening on the edge of our nearest black hole at the moment is actually occurring now, even if a second for it is a millennia for us. Its just that less happens there per our rate or more happens here per the rate there.
Just as time began from the big bang it will also finish when there are only thermal photons left, just because photons don''t have time. Likewise just as space began at the big bang it will cease to be because photons don't "experience" space. You can have as many in the same place as you like. So both time and space are "forgotten" at cosmic thermal equilibrium. so the scale of the universe has no meaning at that point and it is the same as if it were all back in a singularity, ready for the next big idea….. Boom…I mean rapid universal expansion out of equilibrium.
Its just so mental.
Time is perpendicular to light.
