The relationship of photon energy and gravitational signal delay
For a signal traveling around a point gravitational mass , the gravitational delay can be calculated using the following formula:
Here Is a unit vector directed from the observer to the source, and Is the unit vector directed from the observer to the gravitating point of mass M.
It follows that in order to cause a signal delay equal to a fixed and a priori specified time interval mass required
The energy equivalent to this mass is:
On the other hand, the quantum energy of EM radiation with a period is equal to
The product of these 2 energies defined by formulas (3) and (4) is equal to:
Thus, the product of the energy equivalent to the mass causing the delay is equal to , and photon energies with a period independent of and equal to the square of Planck energy up to a dimensionless coefficient: .
Accordingly, the ratio of these 2 energies is equal to
