  2. Sagittarius A* - Wikipedia

    en.wikipedia.org/wiki/Sagittarius_A*

    Sagittarius A*, abbreviated as Sgr A* (/ ˈ s æ dʒ ˈ eɪ s t ɑːr / SADGE-AY-star [3]), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way.Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster (M6) and Lambda Scorpii.

  3. Tidal disruption event - Wikipedia

    en.wikipedia.org/wiki/Tidal_disruption_event

    Tidal disruption event. Simulation of a star being disrupted by a supermassive black hole during a tidal disruption event. [1] A tidal disruption event (TDE) is a transient astronomical source produced when a star passes so close to a supermassive black hole (SMBH) that it is pulled apart by the black hole's tidal force. [2][3] The star ...

  4. Black hole thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Black_hole_thermodynamics

    In physics, black hole thermodynamics [1] is the area of study that seeks to reconcile the laws of thermodynamics with the existence of black hole event horizons.As the study of the statistical mechanics of black-body radiation led to the development of the theory of quantum mechanics, the effort to understand the statistical mechanics of black holes has had a deep impact upon the ...

  5. Black hole - Wikipedia

    en.wikipedia.org/wiki/Black_hole

    Black hole. Animated simulation of a Schwarzschild black hole with a galaxy passing behind. Around the time of alignment, extreme gravitational lensing of the galaxy is observed. A black hole is a region of spacetime wherein gravity is so strong that no matter or electromagnetic energy (e.g. light) can escape it. [2]

  6. Time dilation - Wikipedia

    en.wikipedia.org/wiki/Time_dilation

    Time dilation was used in the Doctor Who episodes "World Enough and Time" and "The Doctor Falls", which take place on a spaceship in the vicinity of a black hole. Due to the immense gravitational pull of the black hole and the ship's length (400 miles), time moves faster at one end than the other.

  7. Gravitational singularity - Wikipedia

    en.wikipedia.org/wiki/Gravitational_singularity

    Category. v. t. e. A gravitational singularity, spacetime singularity or simply singularity is a theoretical condition in which gravity is predicted to be so intense that spacetime itself would break down catastrophically. As such, a singularity is by definition no longer part of the regular spacetime and cannot be determined by "where" or "when".

  8. Binary black hole - Wikipedia

    en.wikipedia.org/wiki/Binary_black_hole

    The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as space-time itself is distorted and dragged around by the rotating black holes. [1] A binary black hole (BBH), or black hole binary, is a system consisting of two black holes in close orbit around each other.

  9. General relativity - Wikipedia

    en.wikipedia.org/wiki/General_relativity

    Slow motion computer simulation of the black hole binary system GW150914 as seen by a nearby observer, during 0.33 s of its final inspiral, merge, and ringdown.The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as spacetime itself is distorted and dragged around by the rotating black holes.
