No, you have misunderstood that. An acceleration would not make the red shift non-linear. What we observe, as we become able to measure the distance to distant objects in other ways than by red shift is that the red shift is not quite linear with distance, and this indicates that expansion is accelerating.
What you according to the omniscient orthodox intolerant holy brainwashed BigBang thesis observes by difference distance estimations techniques must off course 100% refelct the same distance as per redshift interpretation.
So the
accelerating of (so called) dark energy must be the same result everywhere regarding less which technique that is used.
According to the new theory; (the one I and mother cow represent) imaging the Sun would explode, - we know it would take 8 minutes before the orbit of the Earth would be affected. - And before any gravity change would happen here.
Now imaging all stars of all galaxies would explode, - take a look at the image below to understand the point.
Imaging we live in the centre.
You can see that after (let's say 2 million year) the gravity “waves” from 4 galaxies would reach us , - and after passing us , that gravity would be lost, seen from our point of perception.
But after only double so much time gravity waves (not from only 4 galaxies) but now from 12 galaxies would reach us.
So because the periphery of the “bobble” of reachable distance of the Universe “gets larger” propotional with time since all stars of a previous Universe exploded, -- the amount of gravity waves (w/speed of light) that possible can reach us per/ certain time also get larger.
As you can understand we are today hit by a lot more gravity waves (from a previous Universe of exploding stars) as in the past (for example; more now as for few billion years ago). .
THIS explains that we are losing gravity faster now as before, and this is exactly what we can observe in several different ways, - especially in the redshift EM spectra.
Notice the so called "cosmological redshift" is fantasy , - it must be understood as
gravitational redshift .
The whole BigBang idea was derailed already from the beginning; - to be exact exactly the day "cosmological redshift" was
invented (even though it was not necessary)
I believe that many was afraid to suggest that gravity could be extreme in a Big Crunch, since a such would be; "too far from home".
But the alternative 100% pure fantasy invention; "cosmological redshift" have no basic in science at all.
Furthermore a model where god could push the red button would certainly also be supported by several religions. .
In fact the whole load have never ever when been on any real rail at all, - except in fantasy land .
