## Dark Matter vs MOND vs Gravity by EM Waves

**A comparative examination of cosmological observations through three theories**

If both the gravity and Electromagnetic force are due to the properties of the elasticity of the field, then both forces could be unified into one theory system. That won’t be the case in the General Relativity theory which is for large scale and Quantum theory which is for small scale study.

This theory could also mathematically explain and calculate the so-called Dark Energy, rather an unknown repulsing the universe force, as well. Following this direction, we could understand why, when and at what rate our universe expands or contracts.

Here are equations explaining the force between photons or photon and mass:

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)
