COSMIC MONSTERS. “Magnetically charged black holes “can last for the age of the universe for masses larger than about 0.1 kg if unit charge magnetic monopoles have the mass they have in a GUT theory. They can have very large magnetic fields that restore the electroweak symmetry around the black hole. This region can be relatively large.” https://lnkd.in/dX6Fbwx View in LinkedIn

NEAR IMPOSSIBLE. “Producing these black holes artificially looks very difficult, since it would involve producing or gathering lots of magnetic monopoles and then collapsing them into a black hole, even though same sign monopoles repel each other.” https://lnkd.in/dX6Fbwx View in LinkedIn

BOSON SUPERRADIANCE. “The cloud efficiently spins down the black hole to a characteristic critical spin, which depends on the boson mass, through a process called superradiant instability.” https://lnkd.in/gnQbwGA View in LinkedIn

ULTRALIGHT BOSONS. “If such bosons exist and if their Compton wavelengths are comparable to the radius of a rapidly spinning black hole, boson superradiance may take place and generate a hydrogen-atom-like cloud around the spinning black hole.” https://lnkd.in/gnQbwGA View in LinkedIn

This church in Llorá is still standing strong after over 1,000 years. Not much, if anything, that we build today will endure for so long. View in LinkedIn

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

NEEDLES AND HAYSTACKS. “Searches for ultralight bosons using table-top experiments as well as astrophysical observations have been ongoing for years, covering decades of boson mass.” https://lnkd.in/gnQbwGA View in LinkedIn

JUST A TAG. “In fact, the name ultralight boson is commonly used to refer to multiple possible candidates, including fuzzy dark matter, dilatons and axions.” https://lnkd.in/gnQbwGA View in LinkedIn
