Schwarzschild radius - Wikipedia
https://en.wikipedia.org/wiki/Schwarzschild_radius
WEBThe Schwarzschild radius or the gravitational radius is a physical parameter in the Schwarzschild solution to Einstein's field equations that corresponds to the radius defining the event horizon of a Schwarzschild black hole. It is a characteristic radius associated with any quantity of mass.

WEBMar 20, 2024 · Schwarzschild radius, the radius below which the gravitational attraction between the particles of a body must cause it to undergo irreversible gravitational collapse. This phenomenon is thought to be the final fate of the more massive stars (see black hole).

WEBApr 18, 2024 · M⋅G = 10 ⋅ 1.989×1030 kg ⋅ 6.67430×10−11 N⋅m2⋅kg−2 ≈ 13.275×1020N⋅m2⋅kg−1. Divide the result by the square of speed of light (c): 13.275×1020N⋅m2⋅kg−1/ (2.99×108 m/s)2 ≈ 14.77×103 m. Multiply this with 2 to get the Schwarzschild radius (rs): rs = 2⋅14.77×103 = 29540 m = 29.54 km.

WEBBlack Hole Description One of the terms used with black holes is "photon sphere", the radius of the orbit of light around the black hole. For 3 solar masses this radius is 13.5 km, 3/2 x the event horizon radius. The event horizon radius is also called the Schwarzschild radius. Calculation: Index Black hole concepts

WEBKarl Schwarzschild was the first person to note this phenomenon in 1916, but at that time, it was considered to be a mathematical curiosity. Although a black hole cannot be directly observed because light does not escape its event horizon, there is overwhelming evidence that black holes exist in the universe.

https://ned.ipac.caltech.edu/level5/March01/Carroll3/Carroll7.html
WEBTHE SCHWARZSCHILD SOLUTION AND BLACK HOLES. We now move from the domain of the weak-field limit to solutions of the full nonlinear Einstein's equations. With the possible exception of Minkowski space, by far the most important such solution is that discovered by Schwarzschild, which describes spherically symmetric vacuum spacetimes.
