One, the volume contained within black holes represents the absolute greatest amount of entropy that any similarly sized volume in the universe can have. Put another way, black holes are spheres ...

"The Bekenstein-Hawking entropy formula, which describes the thermodynamics of black holes, was discovered in the 1970s," Vijay Balasubramanian, co-author of the paper, told Phys.org.

For an external observer, information about the entropy of the black hole, once borne by the three dimensional structure of ...

Besides particles like sterile neutrinos, axions and weakly interacting massive particles (WIMPs), a leading candidate for the cold dark matter of the universe are primordial black holes—black holes ...

The first major clue came in the late 1990s when theoretical physicist Juan Maldacena calculated the entropy of a black hole. In a nutshell, this calculation of the entropy was a count of all the ...

Called Hawking’s area theorem, this concept states that a black hole’s entropy — which is proportional to the area of its event horizon — cannot decrease. So, even if black holes can lose ...
