Energy Change of Particles or Photons at Crossing Gravity Fields of Galaxy Clusters or Single Stars: The Concept of Gravitons

Abstract

We investigate the gravitational action of cosmic mass associations, like stars or stellar clusters, on moving massive objects. Hereby the relativistic effect of propagating field quanta communicating the position of gravity sources by means of so-called gravitons is taken into account. In case of moving objects this causes an aberration of the recognized actual location of the cosmic mass sources with respect to their positions in the cosmic rest frame. The astonishing effect of that position retardation is that a moving objekt, even if it moves right through the center of a centrally symmetric cluster mass association, experiences a net gravitational braking and energy loss. Applying this view to the problem of a planetary object orbiting around a central mass like the sun, then it turns out that the orbiting planet permanently reduces its orbital angular momentum, since permanently experiencing a gravitational force component antiparallel to its orbital motion. From that an orbital decay time can be derived which for a terrestrial planet would imply the spiralling-in period of only a few 103 years. Compared to the age of the planet earth of about 4. 5 Billion years this represents a big problem of understanding. In this article we cannot offer a rational solution of this problem and thus we simply end with the recommendation to perhaps reinvestigate the theoretical concept of gravitons thought to be the quantum messengers of gravitational fields.
