It is 'space time' that is warped. And if we were wrong about it, your GPS would not work. The exact amount of warping involved because of the speed of the satellites and the gravity of the earth have to be taken into account when correcting for that warp on the atomic clocks on the GPS satellites.
Many of the laws of physics include a time factor. Ato ...[text shortened]... ld be invisible to any measuring apparatus etc, it really wouldn't be any use to anyone.

Originally posted by RJHindsSpace also is warped, and again, we only know this by measuring it. But when our measurements rely on fundamental principles of physics (such as the fact that light in a vacuum travels in a straight line) we say it is the space that is warped. If one shone light in a triangle around the sun (or any massive body for that matter) one would find that the angles do not add up to 180 degrees. This leads to gravitational lensing and be seen in many astronomical pictures.

Now one could say 'light is bent and not space', but since everything would be bent, as far as the laws of physics are concerned it is space itself that is bent and the hypothesized unbent space is nowhere to be seen.

Originally posted by divegeesterOne the one hand, I’ve already acknowledged the correction vis-à-vis “beginning”—as long as it just refers to the possible finiteness of time (to the past).
I don't think these are philosophical concepts, they are scientific ones. Science has demonstrated that both time and space can be affected by either each other, or by mass; therefore they must be able to reciprocate. Time and space are integral to the universe which science tells us had a beginning; therefore time (in relation to this universe) commenced at some point as did space.
On the other hand, it is philosophical in that description of even settled physical phenomena can become inconsistent and nonsensical when language that is time-dependent (or dependent on dimensionality per se) is used in the wrong context: e.g., it is still nonsensical to speak of “before” time (and if time-space dimensionality is part of the universe, to speak of “before” the universe existed).

Never stopping,
it had frozen time itself.

“Time had a beginning” is a strictly nonsensical statement.
Similarly, “Time and space are effects that must have a cause,” is a strictly nonsensical statement.
—It is not just the words that are nonsensical, but the (pseudo-) concepts that the words attempt to express.

Now, not everything can be aware of everything else, but that is simply due
to lack of abilities and limitations nothing more.

I suppose you mean God is only aware of everything else.

that has not happen yet is in the future, everything else is all happening at the
same time, now.
