I recently got a proof of mass energy equivalence from my friend who claims to have it from a very famous professor of IIT , the proove is as follows , please help to find me if there are any errors or arguments .....
Let us consider a photon emerging from somewhere , assuming that there exists a point of time , when it has just emerged , when it's initial velocity is 0 , which we will later proove to be false when we have derived
So, where u is the initial velocity
And where v the final velocity is , speed of light.
Let us assume the distance when the photon reaches the speed
Clearly the initial energy would be 0 ,and the energy gained by it would be the work done by it.
Force is equal to product of mass and acceleration.
We took d/ t to be v because according to Maxwell's equation light shall not change its velocity ever ever.This realisation of Maxwell has occurred to us later here but for which we assume there be some distance d and some time t.
As in quantum physics , energy here is referred as to travel at c so this proof relates and does not contradict Uncertainty principle or quantum mechanics either.
This was the explanation given by the professor , whose name shall not be mentioned, I hoped this would be liked by the brilliantines so decided to share this a matter of knowledge.
Please if any arguments or contradictions that may be raised tell me I may that professor who is my friend's relative
