My second argument tells you: time is made of sensations and their absence. — Bartricks
And there you are wrong. Time is just a coordinate on an apparently 4d-d curved spacetime. It can be associated a number, called the coordinate time. The proper time (eigentime, the own time, which is the one we measure usually in our rather spatially fixed positions, and which in a gravity field loves slower than in flat spacetime, which seems locally to be the case if we fall in a gravity field), is a value that is independent of coordinates values, and it's the time that is measured when you are not moving in the space, I.e, when the spatial coordinates are constant. So in a sense it
is coordinate dependent. You make the spatial part of the metric, explicable in all kinds of coordinates, vanish, and the result is the Lorenz-invariant proper time, meaning just that it's the same in any coordinate system. No matter how fast you go, or where you find yourself, the proper time is always the same. If you are at rest in a gravity field, then the proper time you measure (I.e, the time between two points on your time-like path) goes slower than if you would make such a measurement in outer space because the timeliness metric component is different for you then (in flat spacetime, that component is just 1, or -1, or sometimes even I, if we set c=1). For a spacelike path, followed by light, there is no associated eigentime, as the projection of that path onto the time-axis is zero. So there can be no measuremt of two times. So there is no eigentime of light, which is reasonable as there is no restframe in which light doesn't move. I can remember having a hard time (there you go!) imagining this. On a rocket through space.
This unstoppable character of light, lies at the bottom of SR (and GR, for that matter, which is nothing more than accelerated SR). In a sense you could say that interaction by light is instantaneous, as there is no time passage for light. So in a sense, all thing happen at the same time. Luckily there is space to prevent this.
Note that I use entropic time as the ingredient of this vision. A value can be assigned to it, it's entropic time quantified.
So in this light, can time (so not our subjective experience of it) be assigned to God? It depends. If he is part of this universe, then obviously yes. If they are outside of it? Maybe. It could be that there is a higher dimensional realm, of which our universe is an intersection. While time out there continues, the time at the big bang could have been fluctuating, giving rise to the big bang at their time-like command. Let the be a philosophy forum!
