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.
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 ...
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 ...
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]
The black hole duo is the closest pair found through visible and X-ray light. While other black hole pairs have been observed before, they are usually much farther apart.
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.
Extremal black hole – black hole with the minimal possible mass that can be compatible with a given charge and angular momentum. Black hole electron – if there were a black hole with the same mass and charge as an electron, it would share many of the properties of the electron including the magnetic moment and Compton wavelength.
New observations of several distant giant black holes suggest the mysterious entities play a strong role in shaping their environment – even going as far as to "cook" their own cosmic meals ...
