Without a vacuum demanding to be equilibrated with energy, it gets back to being 'nothing', no cost involved.

But then light won't propagate inside it, even though we define it that way, because you do not have a medium any longer.

Instead you have a beat, and causality defining the observable part of this infinite universe.

Okay, then the other way. A vacuum consisting of 'something', whether you want to call that virtual particles, indeterminism (my choice), or 'energy'. Doesn't really matter as a start.

Why are loaded fridges difficult to budge? Because empty space impedes them.

What's the Energy Density of the Vacuum?

Neither of those are what I think about, although if it now was the way I like to wonder then my ideas need to involve the ideas described above.

I would like the vacuum to be 'gone'
myself, well ideally so. I would prefer it as a symmetry to matter, or 'rest mass'. It's the relation creating a universe, and it need both. You need a vacuum to get to this macroscopic universe.

What it goes back to, for me, is the question if it is correct to think of this universe as a 'container', or not. Actually it should be a duality if I was correct, meaning that it is possible to describe it both ways. After all, we already have a standard theory, using all sorts of descriptions, color forces, gluons and quarks, protons and neutrons, atoms and molecules creating taste and matter. And it works.

Because most of what physics do today, is treating room time as something pre existing, although 'plastic' according to relativity. I like another approach in where a 'SpaceTime' is a local construct, as real as can be, joined through causality and constants into a universe. That allow relativity to be perfectly consistent, without needing to refer it other 'dimensions', as some final 'super container' describing a universe through the 'eyes of a God'. Because that's another assumption you make referring to something that will 'join' relativity and quantum mechanics. And there is one more thing, seems as if people still believe that should be a finiteness ultimately.

And no, it's not that general relativity would be wrong. It's a 'container description' of how the 'energy' is distributed inside a universe. you might call it a description of levers and cogs, balancing a universe. Everything is a description, even 'atoms'. And 'electrons', no matter if you have 'photo graphical evidence' as from Lund university, of a electron 'orbiting'. It's a weird universe.

Einstein saw a 'container' of sorts, his reaction on the question of 'action on a distance' tells me that he did. Without a container model there is nothing forbidding it more than causality and constants. He also seem to have been somewhat agnostic if I read him right, as me too I suspect

It's hard not to be agnostic, considering the weirdness we meet. On the other hand it's really, really, hard believing in us humans as being some sort of 'crown of the universe'. Don't think many do that any more, too much evidence to the contrary.

Get rid of the 'container', define it locally and use constants and causality to define the universe. Causality is the only containment you need, with constants. And causality is about relations to me.

If you define the universe as a sheet, consisting of 'pixels', then you only need some simple rules defining 'change' to create dimensions as I expect. That doesn't guarantee that it must be a discrete universe, it's just easier to describe it that way. If distances wasn't observer dependent according to relativity you would be perfectly correct in finding me dreaming away here, but they are, observer dependent.

and what defines those distances are the anchors consisting of constants, motion, acceleration, and rest mass we (locally) use.

In there a relative motion is experimentally inseparable from being still, locally defined. When using comparisons inside a expected 'container universe' we do see differences though. Now, what do you think is correct there? One or the other, or both?

actually most physics, and especially astronomy, seem to ignore the first. They happily go on defining the 'container universe', but always locally measured.

And 'change' as such is not about lights 'propagation' in my universe
It's just change creating it.

Think of it as a super position, then introduce a 'ground beat', locally equivalent for all SpaceTime positions, that beat also becomes a local arrow and a limit called 'c'. Through the local beat you will get outcomes. With a 'relation' defining your comparison between your local, versus, some other SpaceTime position. Somehow the vacuum, now ideally consisting of a 'nothing at all' not even indeterminism, come into play here. It's very weird idea, as it assume a vacuum to not be existent, but it fits your local reality in where a distance can be shrunk, not to a nothing, but very close to it.

Imagine yourself 'moving' uniformly, extremely fast relative the rest of your universe. Will the light bulb in your room have an extra energy? due to the motion you define outside that 'black room' looking at the rest of the universe?

What about the local arrow, will you now become immortal? due to that uniform motion putting you infinitely close to 'c'. and what about the universe you see, will it age faster? and what about the distances you measure in the direction of your relative motion, versus the universe? Should it shrink?

and that motion is still equivalent to no motion at all, locally defined. And locally defined experiments are what we use, for everything, all hypotheses, all theory's.
