The Black Hole is a community center located in the G 11/3 area of Islamabad, Pakistan. [1] It is a "non-profit, open-to-all educational and intellectual space" with a view to promoting science, art and culture in Pakistan. [ 2 ]
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 ...
Open Library is an online project intended to create "one web page for every book ever published". Created by Aaron Swartz, [3] [4] Brewster Kahle, [5] Alexis Rossi, [6] Anand Chitipothu, [6] and Rebecca Hargrave Malamud, [6] Open Library is a project of the Internet Archive, a nonprofit organization.
This book is a collection of essays and lectures written by Hawking, mainly about the makeup of black holes, and why they might be nodes from which other universes grow. Hawking discusses black hole thermodynamics, special relativity, general relativity, and quantum mechanics.
A binary black hole (BBH), or black hole binary, is an astronomical object consisting of two black holes in close orbit around each other. Like black holes themselves, binary black holes are often divided into binary stellar black holes , formed either as remnants of high-mass binary star systems or by dynamic processes and mutual capture; and ...

1966 — Yakov Zel’dovich and Igor Novikov propose searching for black hole candidates among binary systems in which one star is optically bright and X-ray dark and the other optically dark but X-ray bright (the black hole candidate) [1] 1967 — Jocelyn Bell discovers and analyzes the first radio pulsar, direct evidence for a neutron star [2]
Hawking radiation – black-body radiation that is predicted to be emitted by black holes, due to quantum effects near the event horizon. [2] Penrose process – process theorised by Roger Penrose wherein energy can be extracted from a rotating black hole. Bondi accretion – spherical accretion onto an object.
