Please don't mark as duplicate. My specific question was not answered in other posts. And this question here Which Photon would win the race?
is also about neutrinos, electrons.
My question now is only about photons, and the shapiro delay.
then if you try to make analogy to the shapiro delay, then comes my question:
- according to the shapiro delay, a photon going around the mass arrives later then it should.
- there is no experiment where they would somehow shoot a photon also through the center of mass (maybe between two close stars or an artificial mass with a whole through it, or something else)
- so shapiro delay only talks about the photon going around, and that photon needed more time to arrive from point A to B, but it's speed had to stay c, so the distance it traveled had to be longer (which it really is in 3D)
- so a photon going through a tunnel through the center of mass (or between the two SUNs here) has to travel at speed c too, but its distance is shorter in 3D so it's time need to be shorter too. So that photon has to arrive from A to B faster.
- Imagine this set:
- We shoot two photons, one around one of the stars, and one inbetween two stars.
- We shoot the one going around in an angle that it will cross point B too.
- so was there any experiment like this?
- Am I right that time dilation would affect the photon going between two stars more and it would arrive first?
