(I) First Equation is Einstein's Energy equation:

E=m.c^2 (unit: Joules = kg.m^2/s^2)

My assumption is: where g is gravity (unit: m/s^2) on one specific point of space and, T is period (unit: seconds) of a particle,

This equation could be valid for the speed of light,

**c=g.T**(unit: m/s).

So, where gravity increases, period of the particle/wave should decrease, as c (speed of light) is constant.

So first equation could be written as

**E=m.(g.T).c**

(II) For second energy equation:

c=g.T and T=1/f → c=g/f also c=λ.f

if we multiply c^2=λ.f.g/f → c^2=g.λ

E=m.c^2 →

**E=m.g.λ**(unit: kg*m/s^2*m = kg.m^2/s^2 = Joules)

(III) And third equation is for energy of photon:

**E=h.f**(joules)

To calculate wavelength, use the below formula:

c^2=g.λ → λ=(c^2)/g

---

3rd energy formula outputs energy for photon very small value (around level of 10^-40 joules),

so to calculate the mass of photon, I use formula (II) = formula (III), m.g.λ=h.f → m=h.f/m.g

Mass of photon is calculated around 6,74E-57 kg,

With the help of ChatGPT, i made assumptions for the mass of photons, thru luminosity and energy formulas for several stars. See the table below:

Lastly, from momentum formula point of view:

λ=h/p → p=h/λ

m.v=h/λ → m.λ=h/c

so if h (Planck constant) and c (speed of light) is constant, then mass x lambda should also be constant,

if mass increases, wavelength should decrease, and vice-versa.

According to table, if we compare the mass of a photon, it could be between from 10^-57 to 10^-33 kg,

while wavelength is big, mass is small, and vice-versa.

Photons could have a variable mass related with the wavelength. It could be transforming from a wave particle to a very tiny massed energy packet but we yet can't observe.
