Isn't there a curved photonic beam method that technically, in space, can send a photon around the world at least once?
Airy beams curve
This type of amplification preserves the curvature of Airy beams FWIU:

What kinds of sensing would be possible given a round-the-world photon trajectory?
Quasiparticles have mass, and so might be easier to send around the world than purportedly massless photons.
SQR Superfluid Quantum Relativity with a dilatant fluid says that the effects of mass energy equivalence at high velocities approaching c are actually due to the (atmospheric to superfluiic) viscosity of spacetime nonlinearly pushing back.
But does that matter for a photon or a massless quasi-particle like a photon that we're trying to curve initially to send around the earth at least once to win teh line of sight distance ranking?
- westurner 9mo agoThere is a theory that the star shafts of the Great Pyramid could have been used as waveguides. They did contain copper rods. Perhaps they were just lightning rods. If so, then the pyramids (and other ancient megalithic structures with quartz at 72 degree intervals) and Angkor Wat and Longyou caves and Osireon may have been the longest (non-) line of sight communication system back then in ancient times: https://gemini.google.com/share/101970a04402 https://gemini.google.com/share/101970a04402 Observation of a salt-formed Hydrogen-tuned NV-center diamond might resolve some of these claims?
