Black Hole

Slang; a project that takes an inordinate amount of time to complete. For example, if a contractor spends so much time on one client that she cannot devote enough time to other clients to satisfy their needs, the first client is known as a black hole. The term is most common in accounting and auditing.

"Our universe may exist inside a black hole," he stated in an article he wrote for (https://www.insidescience.org/news/every-black-hole-contains-new-universe) Inside Science .
The team believes they have found part of the solution to this puzzle by calculating the likely 'escape speed' a cluster needs to have to be able to host a black hole with a mass above 50 M?.
So this type of black hole should not exist, at least according to the current astronomical theories, but it does.
EHT's lead astronomer, Shepherd Doeleman said that humanity is being given its first view of a black hole, which is a one-way door out of our universe.
Black holes are objects with such strong gravity that everything, including light, is sucked in and cannot escape.
Mar Mezcua (Institute of Space Sciences, Spain) and colleagues pored through the Chandra COSMOS Legacy Survey to find 40 dwarf galaxies with actively feeding, middleweight black holes. The team used this fraction of active black holes--roughly 10% --as a proxy for the total fraction of black holes, arguing in the August 1st Monthly Notices of the Royal Astronomical Society that the low number favors the latter, direct-collapse model.
Supermassive black holes can also pull in black holes from elsewhere, but until now the search for them has proved fruitless.
Astronomers spot black holes by observing the patterns of objects that encircle the black hole or watch the demise of a star as it releases energy.
The newly discovered supersized black hole resides in the center of a massive elliptical galaxy, NGC 1600, located in a cosmic backwater, a small grouping of 20 or so galaxies, said lead discoverer Chung-Pei Ma, a University of California-Berkeley astronomer and head of the MASSIVE Survey, a research project analyzing vast galaxies and supermassive black holes in the universe.
Washington, May 24 ( ANI ): A team of astronomers using NASA's Wide-field Infrared Survey Explorer (WISE) to survey more than 170,000 supermassive black holes have now decided to re-examine a decades-old theory about the varying appearances of these interstellar objects.
Lead researcher Professor Chris Done, in the department of physics, said: "We know the black hole in the centre of each galaxy is linked to the galaxy as a whole, which is strange because black holes are tiny in relation to the size of a EXPERTS from our region have made a discovery about 'supermassive' black holes which could lead to a better understanding of how they help galaxies grow.
