“But you will certainly be marked as a pariah if you release a study that questions the accepted facts.”
The observed rotation rates of galaxies (among other observations) does not match the rotation rates predicted by General Relativity. This observation can be reconciled with GR by assuming that 90+% of the universe consists of a combination of dark matter/dark energy whose existence, quantities, and distribution cam be deduced from the requirement that the universe behave–precisely–as predicted by GR.
There have been a few brave souls who have suggested that the observed behavior of the universe at large calls into question the ‘ironiclad-ness’ of GR and suggested theories which differ from GR at the limits and explain the observations without the requirement of either dark matter or dark energy. Look them up and see how their careers have blossomed. Or not.
Much like the careers of ‘Climate Scientists’ who question either part of the ‘Prime Axiom of Climate Science’.
