CONSEQUENCES OF NEW THEORY. “Using these concepts, the equivalence principle is understood in a coherent way, and the quantitative description of perihelion precession, gravitational deflection of light and Shapiro time delay are obtained for Schwarzschild metric.” https://lnkd.in/dATr5iE7 View in LinkedIn

NEW THEORY. “According to the observer's position, the gravitational field refraction index is divided into local gravitational field refractive index and non-local gravitational field refractive index.” https://lnkd.in/dATr5iE7 View in LinkedIn

MODERN SPECULATION. “The present authors continued and developed Einstein's views on aether. In a previous series of articles, we have introduced the relative motion refractive index and the gravitational field refractive index using the space-time metric of special relativity and general relativity respectively.” https://lnkd.in/dATr5iE7 View in LinkedIn

ABHORS A VACUUM. “At present, there is a consensus that space is not empty.” https://lnkd.in/dATr5iE7 View in LinkedIn

FUDGE FACTORS. “In order to explain these phenomena, the concepts of dark matter, and later dark energy, have been introduced. These concepts, like the aether, express our ignorance about the nature of space.” https://lnkd.in/dATr5iE7 View in LinkedIn

FROM QUANTUM TO UNIVERSE. “At the same time, with the development of astronomical observation technology, many puzzling astronomical phenomena have been discovered.” https://lnkd.in/dATr5iE7 View in LinkedIn

SO ENDS this remarkable essay on the nature of the ether, a concept that simply has not succeeded in being killed. Once consider a type of superstitious fudge factor with roots in alchemy and phlogiston, the idea of space being empty has not been accepted, and redefinitions of the ether idea -- space as sone type of liquid in which things like light and magnetism are propagated -- continue to arise. This is one of the more imaginative theories. https://lnkd.in/dATr5iE7 View in LinkedIn

THE JOURNEY MATTERS. “In trying to put together observations, hypotheses, and full-fledged theories, I could often see the trees but not the forest. I did not try to erase the footprints of my beating around the bush, because I believe the search is no less instructive than its eventual results, especially when the undertaking is still underway.” (By the late Professor Marcelo Dascal, at Tel Aviv University). https://lnkd.in/dKNrQwQw View in LinkedIn
