Deceleration of massive bodies due to forehead and backhead collisions with gravitons

Abstract

The additional deceleration of massive bodies in the model of low- energy quantum gravity due to forehead and backhead collisions with gravitons is re-calculated in this note. It is shown that this deceleration w is equal to: w = −H0c · 4v2/c2 · (1 − v2/c2)0.5, where H0 is the Hubble constant, c is the velocity of light, v is the body’s velocity relative to the background.
