Just do GR with different variable seems to be the pattern

Here the idea is that different regions of space move differently from others and when each region of the universe extrapolates the effect, each region will have the illusion of expansion. These theories are all about changing the reference variables. Einstein simple rewrote the equations with respect to gravity and space impedance. I just wrote them with respect to a stupid little unit of vacuum. 

In other words, my approach is to find the smallest 'kernel' of vacuum that maximizes entropy over the all of the equations of physics. The equations of physics are a finite set, so whenever my little vacuum kernel broke a rule, I went back and changed it. Eventually my kernel matched the equations.


The Accelerating Universe and Dark Energy Might Be Illusions
Now, a new theory suggests that the accelerating expansion of the universe is merely an illusion, akin to a mirage in the desert. The false impression results from the way our particular region of the cosmos is drifting through the rest of space, said Christos Tsagas, a cosmologist at Aristotle University of Thessaloniki in Greece. Our relative motion makes it look like the universe as a whole is expanding faster and faster, while in actuality, its expansion is slowing down just as would be expected from what we know about gravity.
If Tsagas' theory is correct, it would rid cosmology of its biggest headache, dark energy , and it might also save the universe from its harrowing fate: the Big Rip. Instead of ripping to bits, the universe as Tsagas space-time envisions it would just roll to a standstill, then slowly start shrinking.
Cruising through space-time
Tsagas' alternative version of events, detailed in a recent issue of the peer-reviewed journal Physical Review D, builds on a recent discovery by Alexander Kashlinsky, a cosmologist at NASA's Observational Cosmology Laboratory. In a series of papers over the past three years, Kashlinsky and his colleagues have shown that the huge region of space-time in which we live a region at least 2.5 billion light-years across is moving relative to the rest of the universe, and fast.
