Who discoverd black holes?

Answer 1

Black holes were described theoretically before evidence for their existence was collected from astronomical observations. The philosopher and geologist John Michell in the late 18th century described what would happen to infalling matter approaching a body of a certain mass where it had sufficient acceleration from gravity to approach the speed of light, and proposing the idea that light theoretically emitted by it would be unable to escape; but it wasn't until Einstein's General theory of Relativity (1915) that the framework of gravitation was in place and the reality of black holes could be described mathematically. Building upon Einstein's work, the effect of gravity on light was much better understood and solutions to his field equations yielded much more accurate models of black holes' properties and strong theoretical evidence for their existence. Observational evidence came later, and because black holes cannot emit light, the evidence was indirect, in the form of certain x-ray sources, relativistic jets, quasars or galactic nuclei, and orbital motion of massive bodies. Credit for discovery of the first strong black hole candidate in an x-ray binary system (Cygnus X-1) goes to Bolton, Murdin, and Webster in 1972.

Answer 5

Late 18th century philosopher and geologist John Michell gets credit for first describing the theoretical existence of a black hole, although they weren't given that name until later; Einstein's equations were first to describe them mathematically in the framework of gravitation within General Relativity which required their existence. Schwarzschild was the first to provide a solution for Einstein's field equations (for a non-spinning black hole).

While these are discoveries they are largely in the theoretical realm, proof of the existence of a black hole from observational evidence is much more difficult to obtain since they can't be observed directly, but convincing proof came around 1972 with observations of Cygnus X-1 which was a suspected black hole candidate, by astronomers Murdin, Bolton, and Webster.

Answer 6

Black holes were first proposed by Albert Einstein's theory of general relativity. The term "black hole" was coined by physicist John Archibald Wheeler in 1967. The first black hole candidate was discovered in 1971 in the constellation Cygnus.

Answer 7

Karl Schwarzschild theorized it but John Wheeler expanded on the idea and coined the term 'black holes'.

Answer 8

No one discovered it. It is still not known for sure if a supermassive black hole does exist at the centre of our Galaxy.
