Finally, because the expressions incorporate the Planck constant, which is normally associated with quantum phenomena, and both the speed of light and the universal constant of gravitation, which are often associated with relativistic and gravitational phenomena, these "particles" seem to have been elevated to a position of importance and even physical reality which is difficult to justify.
