The cosmic Big Bang was long believed to be associated with a decelerating expansion of the universe, until recent observations of distant supernovae indicated accelerating expansion that requires dark energy, which is still not fully understood. It is proposed here that cosmic acceleration may be an illusion caused by gradually increasing rest mass, which produces an additional contribution to the apparent cosmological red shift. A novel simple model is presented that illustrates this effect without dark energy, whereby there is a smooth transition from an early universe of massless particles to the present universe of massive particles, stars, and galaxies, mediated by the decreasing gravitational potential of the expanding universe. Implications of this model for the cosmic microwave background and the early universe are discussed.
