In this video I will calculate gravitational redshift photons experience when trying to escape Sun's, white-dwarf's, and neutron star's gravitational forces (Part 2).

Next video in this series can be seen at:

Sir you have the wrong radius for the sun by a hey factor of two. However your video is very revealing And valuable

Can i set the gravity potential energy as the relativistic Ek equation to aplly this to strong gravatational fields like Kerr black holes?(In which the velocity is the falling speed)

I have a question, is the energy lost by the same photon due to a gravititional field is accumulated ( like at r1 i will lose GMm/r1 then at r2 it losses again GMm/r2 ) ?

other question, if the potential energy was subtracted once at some point from the total energy, why should it be compared again to the total energy, why don't we just check whether the total energy after subtraction is positive or not ?

Sir, if PE=-0.5hf, E_T is still positive. Why the photon cannot get rid of the star?

And fun fact, if yo set r=2GM/c^2 yo will get wierd things because it is the event horizon😊
