<\/a><\/p>\n

The \u201cno-hair theorem<\/a>\u201d of black holes, which greatly simplifies the way we model them, may not be true if an alternative theory of gravity known as the teleparallel formulation is correct, an unpublished paper argues. This could make the study of black holes considerably more complicated, but it would also allow physicists to understand them in ways many have feared they never will.<\/p>\n

According to the \u201cno-hair theorem\u201d, a black hole\u2019s mass, electric charge, and spin can tell us everything there is to know about that hole. Anything else we might measure, such as its magnetic moment, can be derived from these three measures.<\/p>\n

Crucially, that means that when matter is swallowed by a black hole\u2019s event horizon, all the information contained within it is lost, once the black hole has emitted any gravitational waves or light associated with its meal. It doesn\u2019t matter what elements went into forming a black hole\u2019s predecessor star, or even if it was made of antimatter rather than matter \u2013 under the no-hair theorem, it would appear identical to anyone outside its event horizon<\/a>. The term \u201chair\u201d is a metaphor for information streaming out of a black hole beyond the point of no return for incoming objects.<\/p>\n","protected":false},"excerpt":{"rendered":"
