GRAVITATIONAL RED SHIFT

THIS EFFECT IS REAL, BUT IT IS WRONGLY ATTRIBUTED TO GENERAL RELATIVITY OF EINSTEIN.
1ST, IT IS DUE TO CONSERVATION OF ENERGY INSIDE A GRAVITATIONAL FIELD AS IT IS KNOWN ,SINCE ABOUT 200 YEARS AGO.
2ND, IT DUE TO THE QUANTUM CHARACTER OF LIGHT E=hν.
A PHOTON FROM A GRAVITATION POTENTIAL U₁  MOVES TO A POINT WITH POTENTIAL U_2.
 

THEN THE DIFFERENCE IN CORRESPONDING OF THE PHOTON, WHICH IS KNOWN TO STILL MOVE WITH THE SAME VELOCITY IS PAID BY THE ENERGY OF THE PHOTON ITSELF WHICH THE ONLY WAY TO PAY THIS ENERGY IS BY RED SHIFTING ITS FREQUENCY ν.
THEREFORE, THE INITIAL ENERGY OF THE PHOTON E₁
=hν₁  AND THE FINAL ENERGY E₂=hν_2,  

 E₂ -E₁=h(v₂-v₁). THEREFORE

v₂-v₁=(E₂ -E₁)/h={m₂-m₁)c²/h,

AND v₂/v₁=U₂/U₁
