The better measurements that scientists want and describe in this article could better determine what the Munozian constants are in my proposed model of the Universe, where the fractal distribution of all the big bangs explain both the values of so-called "dark" and "normal" gravity, plus the accelerated expansions of all the big bangs.
What it won't do is shed light on the nature of bad, vague neo-theories like Dark Matter and Dark Energy.

Proving the Relativistic Energy-Momentum relation, the hard way and the easier way.
This adds the proof for the relativistic mass effects from motion, proving that gravity causes it.
Two reference frames in motions are not symmetrical. A system at rest on the surface of a planet moves faster in time than a moving system. This is not the case using just Special Relativity. This is proven just using the gravitational metric field in General Relativity.
