There is one thing for sure we must solve the problem of what retards the movement of matter light or maybe any substance in what we call space in other words we must find out what space is…what it is made of …

It looks like they developed their own software and made it available https://github.com/eltevo/avera. Does the Astonomy/Cosmology community have open source software projects that provide libraries that one can import into their own software and not rewrite the same function(s)?

Of course 🙂
But having special relativity adds a dimension to the geometry, and one must imagine coordinate lines of time curving into space-like surfaces in order to understand attraction.
Whereas any geometric model of gravity, even one that doesn’t give correct results or reflects reality, still contains a principle of equivalence, and may contain a cosmological constant.

Special relativity isn’t a complication. It’s how the universe works.

There’s a qualitative model of the force of gravity, that is geometric and can include a cosmological constant, without the complications of special relativity.

In this model, masses don’t move at all, rather the space between two masses shrinks with time, and the space far away from all masses expands with time. If the rates of expansion and contraction are balanced just right, the total amount of space remains the same. Otherwise, depending on the exact balance, either the universe will converge to a single point, or the large expanses of empty space will expand forever. And this expansion is accelerating similarly to what we see from distance supernovas: the size of voids will grow exponentially with time.

Saw information on this paper and was hoping you would write about it. Very interesting, though as you say not overwhelmingly convincing.
