  2. Black hole - Wikipedia

    en.wikipedia.org/wiki/Black_hole

    A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...

    en.wikipedia.org/wiki/Tidal_disruption_event

    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 undergoes spaghettification, producing a tidal stream of material that loops around the black hole.

  4. GW190521 - Wikipedia

    en.wikipedia.org/wiki/GW190521

    GW190521 is a significant discovery due to the masses of the resulting large black hole and of one or both of the smaller constituent black holes. Stellar evolution theory predicts that a star cannot collapse itself into a black hole of more than about 65 M ☉, leaving a black hole mass gap above 65 M ☉. The 85 +21 −14 M ☉ [note 3] and ...

    en.wikipedia.org/wiki/Event_horizon

    Far away from the black hole, a particle can move in any direction. It is only restricted by the speed of light. Closer to the black hole spacetime starts to deform. In some convenient coordinate systems, there are more paths going towards the black hole than paths moving away. [Note 1]

    When pairs of phonons were created near the analogue black hole, Steinhauer observed one particle falling in and the other escaping. This, he said, is analogous to a photon escaping a real black hole.

  7. Galactic Center - Wikipedia

    en.wikipedia.org/wiki/Galactic_Center

    The supermassive black hole Sagittarius A*, imaged by the Event Horizon Telescope. [32] The complex astronomical radio source Sagittarius A appears to be located almost exactly at the Galactic Center and contains an intense compact radio source, Sagittarius A*, which coincides with a supermassive black hole at the center of the Milky Way.
