Well, I asked if it was possible. If it is, we would have two 100% identical laserbeams ending up being not 100% identical anymore, due to different experience to redshift. Which could provide some extra information.
Objects, like mountains and buildings, have their own gravitational field. A beam going through a vertical narrow hole in a massive mountain should therefore experience more gravitational redshift than a beam going through a vertical hollow structure. Time goes faster the further away you are...
Don't know if this is the right forum, but I'll give it a try: If you build a bridge over a gorge that's a couple km deep the middle of the bridge would be as far away from the mountains on both sides as possible (and therefore as far away from the mountains' gravitational field as possible)...
Thanks for replying and the explanation about superpositions, but since we are talking about lightyears here, the question is still about how light travels through space.
Maybe it is simpler if we take it one step at the time: A photon travels through space as a wave, which is a simplified...
But this is not about how matter and light interact. It's about light being affected by gravity.
As for waves; if a bullet from a gun had the same properties as a photon, and you were firing against a target, and you had a camera that somehow could film it in slow motion before it was hitting...
To clarify what I meant. A photon travels through the universe as a wave. If a part of this wave is captured by the gravity of a black hole without its wave function collapsing (and without passing the event horizon), and then continue its journey (perhaps after orbiting it a few times), it...
When a photon travels through space it is spreading out like a fan while in its superposition (except that it is spreading also vertically in addition to horizontally). So, what happens if for instance the right outer edge of the photon's superposition is captured by the gravity of a black hole...
