This arrived in my morning “Medium” daily selection e-mail, and I thought interesting to share here, but not LENR related, and frankly, exotic enough to belong to the Playground thread, as a ray of “antigravity” that is measured to be 64x faster than light and not loose energy after passing through concrete houses and traveling 1,2 Km., it’s kind of Sci Fi, but the researcher claims and experiments are published.
They say the stones markings are from a fabric weave but I have wondered if the pattern was more of a wave as it expands thought-out.
