Equations of force between photons or photon and matter with mass

  • 1. Xi'an Jiaotong University


F=Y_1 (f_1 f_2)/r^2 (gravity force between photon and photon)

F=Y_2 f m/r^2   (gravity force between photon and mass)

F – gravity force between two photons or photon and an object with mass
Y_1 =  3.61 × 10^−111 𝑚^3 𝑘g

Y_2 = 4.91 x 10^-61 m^3 s^-1
f – photon frequency
m – mass of object
r – distance between two photons or object with mass and photon

These equations are from the paper “Unified Field Theory for Gravity and Electromagnetism and Its Explanation for Dark Matter Observations” by Max Gaofei Yan, March 27, 2020:
