THE 'HUBBLE TENSION': THE 'HUBBLE CONSTANT' OR 'HUBBLE VARIABLE'?

There are two accurate means of measuring the Hubble parameter that do not agree. This has caused a crisis in cosmology for various esoteric reasons. However it is possible that BOTH MEANS / COLLABORATOR GROUPS ARE CORRECT, and pointing to the Hubble parameter as a variable rather than a constant, as follows. One group measures H0= 73 km/s per Mpc, and the other H0 = 68 km/s per Mpc. One group is looking further back in time and space than the other. If both groups are correct they cannot be correct at the same time. Assuming constant acceleration: A = [(73 km/s)^2 - (68 km/s)^2] / 2 Mpc = 8.5 x 10^-14 m/s^2. Alternatively, A = [(70 km/s)^2 - (0 km/s)^2] / 2Mpc = 7.9 x 10^-14 m/s^2, where 70 km/s is a rough average and 0 km/s is with reference to an observer on Earth. Both values are similar, and amount to describing the Hubble parameter as an acceleration. This conforms with the observation that the Universe is accelerating, and suggests the acceleration is similar throughout the visible universe, and that the Hubble parameter, while a variable, is an unchanged variable throughout the visible universe -- or that current observational evidence indicates that THE ACCELERATION OF THE UNIVERSE IS EVERYWHERE AND EVERYWHEN THE SAME.
