WebSep 12, 2024 · Scientists at MIT and elsewhere have “heard” the ringing of a newborn black hole for first time. The results support Einstein’s theory and the idea that black holes have no “hair” —idea that black holes exhibit just three … It has been proposed that "hairy" black holes may be considered to be bound states of hairless black holes and solitons. In 2004, the exact analytical solution of a (3+1)-dimensional spherically symmetric black hole with minimally coupled self-interacting scalar field was derived. See more The no-hair theorem states that all stationary black hole solutions of the Einstein–Maxwell equations of gravitation and electromagnetism in general relativity can be completely characterized by only three independent … See more The no-hair theorem was originally formulated for black holes within the context of a four-dimensional spacetime, obeying the See more Counterexamples in which the theorem fails are known in spacetime dimensions higher than four; in the presence of non-abelian Yang–Mills fields, non-abelian Proca fields, some non-minimally coupled scalar fields, or skyrmions; or in some theories of gravity … See more A study by Sasha Haco, Stephen Hawking, Malcolm Perry and Andrew Strominger postulates that black holes might contain "soft hair", giving the black hole more degrees of freedom … See more Suppose two black holes have the same masses, electrical charges, and angular momenta, but the first black hole was made by collapsing … See more Every isolated unstable black hole decays rapidly to a stable black hole; and (excepting quantum fluctuations) stable black holes can be completely described (in a Cartesian coordinate system) at any moment in time by these eleven numbers: • See more The LIGO results provide some experimental evidence consistent with the uniqueness of the no-hair theorem.
