These scientific mistakes are a misunderstanding of how gravity works leading to a misreading of why the redshift of light from distant objects occurs.  Gravity is a direct pull on space and light from the emitter is pulled back every inch of travel.   Gravity is the weakest of all the forces so no redshift occurs within galaxies.  This is what is expected of gravity. Astronomical distances are travelled before redshift appears.  How long before
NEW GRAVITY becomes the dominant theory ?
