BIOLOGICAL SYMBOLIC STRUCTURES. “If propositions are symbolic constructions which may exist in mind apart from language, this suggests that there must be symbolic systems in the brain, unrelated to human languages and developmentally prior to them. In other words, it’s possible that there are symbolic mechanisms of a biological nature which are fundamental to human activity.” (Charles Pinter, Mind and the Cosmic Order, a fabulous book). https://link.springer.com/content/pdf/10.1007/978-3-030-50083-2.pdf View in LinkedIn

INDIRECT METHODS. “Gravitational-wave (GW) measurements of black holes in binaries (BBHs) provide a unique opportunity to detect or rule out the existence of these ultralight bosons in a mass range which is commensurate to the black holes masses and not accessible by lab-based experiment.” https://lnkd.in/gnQbwGA View in LinkedIn

THE MIGHTY AND THE TINY. “But the physicists have found that two previously detected black holes are spinning too fast to have been affected by any ultralight bosons. Because of their large spins, the black holes’ existence rules out the existence of ultralight bosons with masses between 1.3×10(-13) electronvolts and 2.7×10(-13) electronvolts — around a quintillionth the mass of an electron.” https://lnkd.in/dRWpnua View in LinkedIn

NEWTON’S ABSOLUTE TIME AND SPACE. “Newton would have been surprised at the modern quantum theory and at the dissolution of quanta into vibrations; Plato would have expected it. Physicists are now explaining these chemical facts by means of conceptions which Plato would have welcomed.” https://lnkd.in/g4ntepe View in LinkedIn

THE FINE PRINT IN WONDERLAND. “This simple idea is made more complicated by a few factors. First, one must take into account that some black holes may be slowly spinning when they form. The small spin measurements inferred from the BBH mergers observed by LIGO/Virgo could be due to either the superradiant growth of the boson cloud or an astrophysical distribution favoring small spins at the formation.” (BBH = binary black holes). https://lnkd.in/gnQbwGA View in LinkedIn
