When one steps on the gas of a car, the car accelerates.  Graphically, this looks like.

The above graphs represent the typical expression of acceleration and deceleration.   Now let us look at a plot the velocity of type 1a supernovas on a similar graph.   Since distance away corresponds to observation of objects in the past, the velocity of 1asn can be plotted in time.  The further away the 1asn, the more in the past the object is observed.

Note that the slope of the graph for the velocity of galaxies over time indicates deceleration, not acceleration.   An object moving faster in the past than the present indicates deceleration.   The further away a galaxy is, the further in the past it is observed. The more in the past the galaxy is observed, the faster it’s observed recessional velocity. An object moving faster in the past than the present is decelerating; our universe is decelerating.   An observer on a near by galaxy would be observing our cosmological expansion as it presently occurs.  An observer on a far off galaxy would be observing our cosmological expansion as it occurred in the past.   Our own galaxy would be observed to have a cosmological expansion rate that was faster in the past than the present. Our universe is decelerating.   (For those who are from Bad Astronomy checking this out, thanks.  Those so inclined may check out my uniform expansion theory. )
