It sounds neat but I'm skeptical about that too. Making suppositions like that would have to permit something useful for it to "stick to the wall" in my view, much like imaginary numbers turned out to be extremely useful, whether you believe they really exist or not.
Funny thing about interpretations, sometimes we get a little too picky. I mean in terms of QM it's been all over the place right down to consciousness is required, one can't predetermine particle states and the most famous is parallel universes. LoL, The issues with entanglement were violating some sacred QM rules, which obviously is a particle's state can not be predetermined. But if you view entanglement as a nano-wormhole it doesn't violate QM rules since it's the same particle! But allowing for a nano-wormhole that only happens under certain conditions, or reactions puts Ensitien's theories into jeopardy, or does it? I once was active on the string theory board way back when it was still a flaky theory, which is obviously why I was allowed to post on it!
I posted an idea that matter renders space as opposed to the understanding that matter is in a box called space. The idea went further stating that the particles build manifolds by virtue of their motions, which would not exclude hyperspatial dimensions. So manifolds would then overlap over one another which is what we experience as a spatial continuum, and they can also form micro wormholes as they interact with one another. I was so surprised when the board liked the idea, but because it's not a string-theory concept, other than it allows for hyper-dimensions, they felt that the problem of entanglement didn't warrant rewriting relativistic theories!
So I responded to the board by explaining how space-time as viewed by the current interpretation of Einstein's theory would not change much, well it would destroy space expansion.
But two very important discoveries happened since then. One is dark matter, and the other is Higgs boson. So, this is the notion: gravity as a force at distance had some very tough problems, one of which is gravity can not be shadowed or blocked as with other fields where those force carriers are absorbed, so gravitons don't get absorbed. Gravity was the weakest of the fields until dark energy was coined to explain space expansion, and light would have to have some kind of interaction with gravity as does restmass. So, to think of gravity as a force at distance lost out to an idea of space-time curvature where there is no interaction with mass, its space that curves the manifold, so matter has no choice but to follow a path constrained by curved space. But, then Higgs- Boson was discovered and that proved all matter is actually a virtual particle. Add to the idea of dark matter and well...maybe gravity as a force at a distance might work?
Looking at gravity as a force at a distance means that gravity has to interact with matter but gravitons don't get absorbed remember? So how can gravity work as a force at a distance: The Higgs-Boson is an example of particle interactions where particles don't get absorbed. If gravitons had a similar mechanism then they could interact with matter, but never get absorbed! OK, but one would then ask but how can momentum be imparted without energy? You see the absorption of the force carrier is the energy that gets imparted to the particle to move it. Since I'm describing gravitons as particles that interact with matter it could power the momentum force with zero-point energy! So when gravitons interact with matter they grab a free-energy particle and impart momentum to matter, including photons! This idea explains how gravity is powered and why it's so weak. All other force fields work under a net-net concept where each particle gives up a force-carrier photon it gets one back in exchange with a different particle, so no energy is lost!
With this kind of gravity, all the effects of lensing, curved trajectories, gravity waves, black holes, and time-dilation would still work exactly how Enstiens equations predict they would.
All, but space expansion.
But wait! Remember dark matter? The reason we think there is space expansion is the red-shift effect of light from other galaxies receding from us and they appear to be doing it faster than light! Well..would dark matter create a redshift on light coming from those galaxies? But wait, how can I explain the acceleration of the expansion? Well...What if more dark matter is coming into the Universe from outside of it? As more dark matter enters our universe the more red shit we would see. So the measurement made that we thought was accelerated expansion is actually the deceleration of the Universe! So those galaxies aren't expanding away from us they're decelerating and will eventually collapse our universe.
The problem I've always had with dark energy is where does its source come from and why can't we measure it. Zero-point energy has been measured and literally observed with countless experiments demonstrating the Casimir effect, so we know it's real. What if dark matter is really zero-point energy?
The last point, one might ask is why can't we move in a hyper-dimensional direction. Well, that one is kind of easy, since gauge pheonamena is literally bonded together by field effects that operate on an inverse square principle, 3 dimensions are the sweet spot where field densities are strong enough to hold things together. Add an extra dimension and the volume of space increases by a magnitude of order which would lower thier densities. But quantum particles could have such nano-scale motions that would allow for micro-wormholes and spatial superposition.
So, this long-drawn-out post is really about how interpretations of what mathematical models are describing aren't necessarily to be taken literally, they are just models that provide an effective framework to solve problems and predict phenomena. But by changing the interpretation we could get a different, logically equivalent description that could open new horizons. I like being an idealist when it comes to science.
Dare challenge Einstein, he won't mind, I guarantee it...
