:smile: that's why he asked the question (I believe...), so he could "sieve" the reliable answers...

In everyone's case the story is the same: the photon is emitted, then reaches Earth, then absorbed on Jupiter... All the observers use the same Lorentz transformation equation.

I explained to you in the other thread: Do photons experience zero time between emission and absorption?

The proper time for a photon is considered ##\tau = 0##, but most people would say that is not defined, because, apparently, it involve infinity which would cause the math to collapse. But the math is simple: as the velocity approaches speed of light $$\lim_{v \to c^-} \gamma = \infty$$...

Because sometimes the textbook can be wrong... :-p I'm not saying that they are always wrong, but when people don't find them explanatory enough, they seek extra information somewhere else... It's the textbook fault... Do not blame the individual for trying to fully understand the matter in...
