“THE ETHER or aether, in physics and astronomy, a hypothetical medium for transmitting light and heat (radiation), filling all unoccupied space; it is also called luminiferous ether. In Newtonian physics all waves are propagated through a medium, e.g., water waves through water, sound waves through air. When James Clerk Maxwell developed his electromagnetic theory of light, Newtonian physicists postulated ether as the medium that transmitted electromagnetic waves.” https://lnkd.in/dfqNVnY7 View in LinkedIn

FRAGMENT FROM NATURE for this weekend only features an extraordinary article, whose title is ‘A Heuristic View on the Composition of Space’ by Guoxu Feng, at the Jun Huang School of Aeronautic Science and Engineering, Beihang University, Beijing, China. This speculation on the composition of space is startlingly original and tackles an old chestnut called the ether. https://lnkd.in/dATr5iE7 View in LinkedIn

THE BEST GIFT. “If I had influence with the good fairy who is supposed to preside over the christening of all children, I should ask that her gift to each child in the world be a sense of wonder so indestructible that it would last throughout life, as an unfailing antidote against the boredom and disenchantments of later years, the sterile preoccupation with things that are artificial, the alienation from the sources of our strength.” (Rachel Carson, author of Silent Spring).

THE CONTRARIAN EXPERIMENTS. “The vast majority of theoretical physicists believe that, if a difference in acceleration between matter and antimatter exists, it can only be extremely small. Few consider possible an antigravity where antihydrogen would “fall up”, as the CERN presents the three current experiments testing the equivalence principle by the ELENA antiproton decelerator.” https://lnkd.in/daA2SgMy View in LinkedIn

NEGATIVE MASS. “We show that, very surprisingly, the usual expression of the Equivalence Principle is violated by General Relativity when particles of negative mass are supposed to exist, which may provide a fundamental explanation of MOND phenomenology, obviating the need for Dark Matter.” https://lnkd.in/daA2SgMy View in LinkedIn

ELEPHANT IN THE ROOM. “Although the theory of relativity no longer needs the aether, Einstein surprisingly defended it. After the establishment of general relativity, Einstein systematically discussed the relationship between aether and theory of relativity, and gave arguments supporting the idea that aether must be retained.” https://lnkd.in/dATr5iE7 View in LinkedIn
