If you look at plots of the Hubbell Constant you will notice that the rate of expansion of the local galaxies represents a basically flat line, which is a constant rate. It is only at the extreme red shifts, which is in the distant past that any departure from the linear nature is indicated.
If all we do is accept what other say with out questioning it, nothing will ever change. It is very tempting to just accept what “professionals” state. But remember, professionals once believed that offsets and epicycles were what was necessary to describe the motion of the planets in the universe (Copernicus even used them, in fact the Ptolemaic system used 40 circles and offsets while Copernicus used 41). I am certain that eventually you will decide for yourself that the universe is decelerating. You will simply look at the observations and make the most logical conclusion.
