For one thing, it begs the question as to what is space?
Are you sure it isn't a case of fitting a patch to the size of the problem, than going back and trying to figure out where the problem came from in the first place?
There is certainly a strong social tendency to fix problems as they arise, than figuring out the causes, but the eventual consequence is a rather large reality check.
I certainly haven't done all the math, but then I don't need to know all the math involved in epicycles to understand where the problem is. For one thing, a lot of the math in epicycles was patching problems as they arose, rather than figuring out where the problems came from.
Remember as well that when they would come up with a patch, often it would solve more than one problem, which would seem to validate the model. All those cosmic gearwheels turning. The late stage geocentric models were more accurate than the early heliocentric models. For one thing, we can directly see from a geocentric point of view.
Personally, since you are being fairly considerate, I will point out what I see as the biggest problem in physics.
We are mobile organisms, so our experience occurs as a sequence of perceptions, in order to navigate. Consequently we experience time as the point of the present, moving past to future. Physics codifies it as measures of duration.
The reality is that change turns future to past. Tomorrow becomes yesterday, because the earth turns. Duration is the present, as the events coalesce and dissolve. Potential>actual>residual.
There is no literal dimension of time, because the past is consumed by the present, to inform and drive it. Causality and conservation of energy. Cause becomes effect.
So no time traveling around the fabric of spacetime.
Different clocks can run at different rates simply because they are separate actions. Think metabolism.
That human culture is about getting everyone following the same rules, speaking the same languages and using the same measures, it might seem like there is some universal, Newtonian flow of time, but it's rabbit time, turtle time, etc.
Time is asymmetric because it is a measure of action and action is inertial. The earth only turns one direction. Entropy is a second order effect and not what's being directly measured.
Different events appearing in different order from different locations is no more consequential than seeing the moon as it was a moment ago, simultaneous with seeing stars as they were years ago. It's the energy that's conserved, not the information. That the information changes is time.
Energy is "conserved," because it is the present, creating time, as well as temperature, pressure, color and sound. Time is frequency, events are amplitude.
So the energy goes past to future, while the patterns generated go future to past. Energy drives the wave, while the fluctuations rise and fall. No tiny strings necessary.
Consciousness also goes past to future, while the perceptions, emotions and thoughts giving it form and structure go future to past. Though it is the digestive, respiratory and circulatory systems processing the energy, feeding the flame, while the central nervous system sorts the information.
Consequently the intellectual tendency is to focus on the patterns, rather than the processes generating them.
The product goes start to finish, future to past, while the production line goes the other way, toward future products, as it consumes material and expels finished product.
As lives go birth to death, while life moves onto the next generation, shedding the old.
So energy radiates out, as structure coalesces in. Thus galaxies.
