PARTICLE ZOO. “Ultralight bosons are hypothetical particles with masses smaller than ∼ 10(-11) eV. Their existence, if verified, would help solving open problems in particle physics and cosmology.” https://lnkd.in/gnQbwGA View in LinkedIn

BOSONS. “If you jump onto and then down from a carousel, you can steal energy from the carousel. These bosons do the same thing to a black hole.” https://lnkd.in/dRWpnua 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

QED. “Conversely, the discovery of highly spinning black holes could rule out the existence of boson in an appropriate mass range.” https://lnkd.in/gnQbwGA View in LinkedIn

ALICE’S WONDERFUL LOGIC. “Supermassive black holes, such as M87, can be used to probe much lighter bosons, with μs ∼ 10(−21) eV. Roughly speaking, if a dearth of highly spinning black holes is observed for some range of black hole masses, that could be suggestive of the existence of ultralight bosons which have spun down the black holes.” https://lnkd.in/gnQbwGA View in LinkedIn

WONDERLAND ON DRUGS. Probing the massive for the existence of the minute. Ultralight bosons being sought in ultra massive black holes. Wonderland and rabbit holes! The wonderful illogic of the quantum and the cosmos. https://lnkd.in/gnQbwGA View in LinkedIn

UNLIKELY RABBIT HOLE. “Accessing tens or hundreds of BBHs thus allows for statistical tests on the existence of ultralight bosons, in a boson mass range that depends on the mass range of the population of black holes being probed.” (BBH = binary black holes).
