Hawking, Malcolm J. Perry & Andrew Strominger WebFeb 17, 2024 · Conventionally, black holes can be described by only three properties: their mass, their spin and their charge. Therefore, some physicists say that black holes resemble a bald head with no hair. So, if two black holes have the same mass, spin and electric charge, then in theory they should be identical.

WebSep 17, 2024 · Spinning black holes could grow long hair. Isi and colleagues found that the ringdown signal can be described in terms of the fundamental mode of the black hole plus at least one overtone. This, they say, is consistent with the hypothesis that the GW150914 merger created a “Kerr black hole” – which is a black hole with zero electrical charge. WebA black hole is a region of spacetime in which the attractive force of gravity is so strong that not even light escapes. As a result, black holes are not visible to the eye, although they can be detected from the behavior of light and matter nearby. The most well-studied black holes are formed from stars collapsing under the gravitational attraction of their own mass, but …

In my own lay terms the physicists appear to theorize resolving the paradox with with their proposed C = 12 J . C is the central charge (which I don't fully understand) and J is the total angular momentum of the black hole. 12 is an interesting and elegant coefficient (IMHO ...

Black holes (indeed, all masses) disturb the spacetime around them, causing distortion of clocks (time) and rulers (space). In theory, in order to measure traditional charges (hair) like the total mass, one simply arranges some clocks and rulers very close to the object and measures this local distortion. … See more Black holes are among the most extreme objects in our universe, places where gravitational effects get so strong that our current physical … See more Almost every macroscopic object you know is incredibly complex.
