Brandon Carter

Brandon Carter, FRS (born 1942) is an Australian theoretical physicist, best known for his work on the properties of black holes and for being the first to name and employ the anthropic principle in its contemporary form. He is a researcher at the Meudon campus of the Laboratoire Univers et Théories, part of the CNRS.

Biography

Carter studied at the University of Cambridge under Dennis Sciama. He found the exact solution of the geodesic equations for the Kerr/Newman electrovacuum solution, and the maximal analytic extension of this solution. In the process, he discovered the extraordinary fourth constant of motion and the Killing–Yano tensor. Together with Werner Israel and Stephen Hawking, he proved partially the no-hair theorem in general relativity, stating that all stationary black holes are completely characterized by mass, charge, and angular momentum. In 1982 with astrophysicist Jean-Pierre Luminet, he invented the concept of tidal disruption event (TDE), namely the destruction of a star passing in the vicinity of a supermassive black hole. They showed that this phenomenon could result in the violent destruction of the star in the form of a "stellar pancake", causing a reactivation of nuclear reactions in the core of the star in the stage of its maximum compression. More recently, Carter, Chachoua, and Chamel (2005) have formulated a relativistic theory of elastic deformations in neutron stars.

gollark: I don't know if the people designing electoral systems actually did think of voting systems which are popular now and discard them, but it's not *that* much of a reason to not adopt new ones.
gollark: There are plenty of things in, say, maths, which could have been thought up ages ago, and seem stupidly obvious now, but weren't. Such as modern place value notation.
gollark: Obvious things now may just not have been then.
gollark: Hindsight bias exists.
gollark: As I said, a REALLY bad one would be allocating the vote randomly. This satisfies almost nobody, which makes it a "good compromise" by your definition, but it does that because it has tons of flaws.
