Adrien I perfectly agree with everything that you say. I belief that we are thinking in two different problems.

pervect The different of sing is because I used v=t-x. Thank You for the comments.

Prevect I used the definition of light cone coordinates (null coordinates) and I found that the speed in this coordinates is (1-β)/(1+β) such that β is the speed in the inertial reference frame In the case that β=0 we have a speed of unity. In the case of the photon traveling to...

My idea is that if I can find a non inertial reference frame in which stuff can move faster than the speed of light. Why I can't find a non inertial reference frame in which particle that move at the speed of light are not moving? At example of a reference frame in which things can move...

Which part of the lecture notes of David Tong do you want me to read? I suppose that you are using some argument based in the gauge symmetry of the photon. Yes I agree that the U (1) gauge symmetry and Lorentz co-variance will implies that the photon does not has a mass term. You probably...

Thanks I think I can play with light cones coordinates, but I found that it lacks some properties that I would like of the rest frame of a particle traveling at the speed of light. Particularly only the the particle at rest in the original reference frame will "travel" at the speed of light...

I know that the rest frame of the photon is a non inertial reference frame. In that sense obviously the physics will not be Lorentz co-variant and so on. I have the following question Is possible to define a coordinate transformation from an inertial reference frame to the rest frame of a...

In realistic solenoid means that is a helix, that mean that there is a component of the current in the z direction.

Ok I tried to explain it as simple as possible. Obviously you are not a graduate student in physics (first year of graduate studies in physics are enough to understand what I am saying). I gave you reference, videos and links in Wikipedia. My advice is to take a course in quantum mechanics...

What I am saying about mirrors doesn't change the practical behavior of them, just that what is happening is not that simple as you thought. To give you examples that are not related to mirrors. Contact forces as touching and punching are really manifestation of electromagnetic forces. That...

The story of galileo is not that simple, but that is not the point. Mirrors are made of atoms (use an scattering experiment to prove it). Light is composed of photon (use a photomultiplier to check it). Mirrors are not perfect (use a Tem). Atoms absorb an emit photons (use experiments as the...

Here there is a video that present some of the examples of Feynman in the lectures about qed. The complete example of the mirror is not included (adding also absorption, there is only the path integral part), but there is enough concept to understand what I said before. Is about 20 minutes.

I don't need to explain it to opticians, they know that what I am saying is true. I suspect that you don't know quantum mechanics, then I suppose that a good book is: ( I hope that is the case) https://www.amazon.com/dp/0691024170/?tag=pfamazon01-20 This book can be found in internet to...

Seriously were have you been during the last century? Anyway is not my theory. I am just telling you what quantum electrodynamics said. All the experiments that confirm one of the most amazing theories in physics are just illusion, because you think that the mirror in ur telescope is...

I think you misunderstood what I mean. From a special relativity point if a photon is reflected then it mean by continuity that in some moment the velocity of the photon should be zero and then the photon is a rest. (that is a problem.) That is the problem by thinking that the photon was just...
