I've never been able to grap these deep physics arguments. Just because we don't have an absolute God-approved clock to check against doesn't mean there is no such thing as time. Things happens in a sequence. If I put a pot of water on to boil, it doesn't instantly boil. I have to wait until it reaches boiling temperature. That waiting period is clearly time. You can argue about whose clock measures that time the best, but you can't argue that there was a period of time bewteen setting the pot on the stove, and the point when it started to boil.

Likewise with the "grid" concept. The grid is a construct to measure space. The grid might be inaccurate, but it doesn't mean space doesn't exist. And even if the Universe is expanding, or if it's a triangle, it pretty much solves nothing, because of infinity. That triangle, or that expanding Universe, exists within space. But isn't there more space outside that space? I can't fathom nothingness. Even empty space is something, isn't it?

From a Christian standpoint not having time as a real thing makes perfect sense. It would explain how God knows what is going to happen—it already has. But I’m not physics smart enough to understand this stuff. We are concrete beings and to us, time DOES exist just as beginnings and endings exist. Except, I also can’t grasp the concept that everything didn’t ALWAYS exist (that is, it has a starting point) because seems that if there was nothing there would never have been anything. OK, now my head hurts!

A Time Experiment

Step outside:

Now prove which way a sequence went...

cool water in kettle;
burner lit;
kettle boils;

kettle boils;
burner lit,;
cool water in kettle...

Or to put it another way:
If you have a ping pong ball bouncing off two walls - can you prove which wall the ball began bouncing from? There's an article in a very very old Scientific American on this example.

What happens in the middle is called time, but that time may be something subjective and particular only to humans. James Maxwell Clerke posited things happen in fields not vectors (current theoretical physics models). In those theorems, time is simultaneous everywhere. Everything happens at once - we are just incapable of understanding or perceiving it that way.

The perception than time runs forward is an illusion in physics, but one that makes sense to us as humans. However, in a different universe, it might be possible to say that those humans would find the reverse makes more sense for them.

And it is simply a theory that the universe is expanding. While the steady state universe was disproved, it does not mean with all the problems and uncertainties in theoretical physics that it will remain so.

My favorite one is the oft repeated “nothing escapes from a black hole, not even light”. Yet it very clear that something does escape somehow.

Since modern astronomy posits a black hole at the center of every galaxy, nothing should be emitted, but look at any UV/IR image and there indeed is something coming out of the very center of galaxies where nothing should be. No one talks about this wee problem.

Outer space is not empty, but filled with radiations of all kinds. There is nothing we currently know of that actually contains absolutely nothing. We may not be able to graps any of this in our real lives, but it is fun - to me at least - to play with them. :)
