Astronaut falling into a black hole (schematic illustration of the spaghettification effect) Tidal forces acting on a spherical body in a non-homogeneous gravitational field. In this diagram, the gravitational force originates from a source to the right.
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 ...
We can imagine what it's like to fall through the Earth, but you still don't want to fall into a black hole. ... Check out some supermassive black holes in the gallery below: 2 Photos ...
In terms of visual appearance, observers who fall into the hole perceive the eventual apparent horizon as a black impermeable area enclosing the singularity. [21] Other objects that had entered the horizon area along the same radial path but at an earlier time would appear below the observer as long as they are not entered inside the apparent ...
For example, the Schwarzschild radius of the Earth is roughly 9 mm (3 ⁄ 8 inch); at the surface ... This corresponds to the particle falling into a black hole. The ...
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.
(In any "black hole" which we observe, we see it at a time when its matter has not yet finished collapsing, so it is not really a black hole yet.) Similarly, objects falling into a black hole remain outside the event horizon in Schwarzschild coordinates, but cross it in Kruskal–Szekeres coordinates.
With such high mass, TON 618 may fall into a proposed new classification of ultramassive black holes. [11] [12] A black hole of this mass has a Schwarzschild radius of 1,300 AU (about 195 billion km or 0.02 ly) which is more than 40 times the distance from Neptune to the Sun.
