## Does the Distance- Redshift Curve of Receding Galaxies Show an Accelerating or a Decelerating Expansion of the Universe ?

**Authors:** Henok Tadesse

Some cosmologists have noted the profound coincidence of the value of the anomalous acceleration ( 8.74 x 10-10 m/s2 ) of Pioneer spacecraft with the value of the so-called cosmological acceleration, about which mainstream physics has been silent. The starting argument in this paper is that this may not be a coincidence and that both accelerations are manifestations of the same phenomenon.However, the anomalous acceleration of the Pioneer is negative, whereas cosmological acceleration is positive, which would be a contradiction. Therefore, both accelerations must have not only the same magnitude, but also the same sign. This leads us to question of the usual interpretation of distance-redshift curves of receding galaxies, which is based on the theory of expansion of the universe .In this paper, we will show that the universe is in decelerating 'expansion', not accelerating expansion. A decelerating force will increase the time taken for a galaxy to reach a given receding velocity, compared to the time taken according to Hubble's law.Using elementary kinematics we will show that increase in the time taken to reach a given receding velocity will increase the corresponding distance travelled.The longer the time the galaxy is in motion, the larger the distance it will travel. The effect of increase in time will always more than offset the effect of decrease in acceleration.Hubble's law is not due to expansion of the universe; it is due to a modified Newtonian law of gravity. The coincidence of the Pioneer anomalous acceleration with cosmological acceleration disproves general relativity.
