Why hasn't any Astronomer answered the question we are not permitted to ask? The question is:
Assuming that these galaxies "aged" according to the known laws of galaxy formation, how old would they be?
Because the answer would not be 650 million years. It would be more like 14 billion. Cognitive dissonance keeps them from considering being this wrong.

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.
