The Thorne–Hawking–Preskill bet was a public bet on the outcome of the black hole information paradox made in 1997 by physics theorists Kip Thorne and Stephen Hawking on the one side, and John Preskill on the other, according to the document they signed 6 February 1997, [1] as shown in Hawking's 2001 book The Universe in a Nutshell.
Supermassive black holes, regions of space where the pull of gravity is so intense that even light doesn't have enough energy to escape, are often considered terrors of the known universe.
While in a non-rotating black hole the singularity occurs at a single point in the model coordinates, called a "point singularity", in a rotating black hole, also known as a Kerr black hole, the singularity occurs on a ring (a circular line), known as a "ring singularity". Such a singularity may also theoretically become a wormhole. [18]
Fuzzballs are hypothetical objects in superstring theory, intended to provide a fully quantum description of the black holes predicted by general relativity.. The fuzzball hypothesis dispenses with the singularity at the heart of a black hole by positing that the entire region within the black hole's event horizon is actually an extended object: a ball of strings, which are advanced as the ...
Astronomers have detected the signal from a long ago violent collision of two black holes that created a new one of a size that had never been seen before.
Stephen Hawking provided a ground-breaking solution to one of the most mysterious aspects of black holes, called the "information paradox." Black holes look like they 'absorb' matter. Every time a ...
The ISCO plays an important role in black hole accretion disks since it marks the inner edge of the disk. The ISCO should not be confused with the Roche limit, the innermost point where a physical object can orbit before tidal forces break it up. The ISCO is concerned with theoretical test particles, not real objects. In general terms, the ISCO ...
