Abstract

A fiber optic conveyor has been developed for investigating the travel-time difference between two counter-propagating light beams in uniformly moving fiber. Our finding is that there is a travel-time difference Deltat=2vDeltal/c^2 in a fiber segment of length Deltal moving with the source and detector at a speed v, whether the segment is moving uniformly or circularly.

    • Sagnac effect shows that speed of light is not constant and can be changed. [1] http://arxiv.org/pdf/physics/0609222.pdf

    • For me, whole Theory of Relativity and Quantum Mechanics looks like huge scam. Mathematics is Turing-complete, so proper formula with right magic constants can separate dogs from cats (see neural networks for example: they are pure mathematics). However, I had belief in Theory…
