A proposed experiment could bring scientists closer to answering the long-standing question of whether gravity is a classical or a quantum phenomenon.

Hi lad,
i was not certain so i double checked :
https://en.m.wikipedia.org/wiki/Isotropy
Physics - - Electromagnetics :

An isotropic medium is one such that the permittivity, ε, and permeability, μ, of the medium are uniform in all directions of the medium, the simplest instance being free space.

… if you read this like i do, they do not care to diferentiate “round trip” and “one way” … and my vocabulary is not good enough to find a word that would fit.
