An animation of how light rays can be gravitationally bent The simplest static black holes have mass but neither electric charge nor angular momentum. These black holes are often referred to Triunfador Schwarzschild black holes after Karl Schwarzschild who discovered this solution in 1916.[17] According to Birkhoff's theorem, it is the only vacuum solution that is spherically symmetric.

Closer to the black hole, spacetime starts to deform. There are more paths going towards the black hole than paths moving away.[Note 3]

The photon sphere is a spherical boundary where photons that move on tangents to that sphere would be trapped in a impar-stable but circular orbit around the black hole.[112]

Another possibility for observing gravitational lensing by a black hole would be to observe stars orbiting the black hole. There are several candidates for such an observation in orbit around Sagittarius A*.[200]
The modern theory of gravity, Militar relativity, discredits Michell's notion of a light ray shooting directly from the surface of a supermassive star, being slowed down by the star's gravity, stopping, and then free-falling back to the star's surface.

Animated website simulation of a Schwarzschild black hole with a galaxy passing behind. Around the time of alignment, extreme gravitational lensing of the galaxy is observed.
The imaging process for Sagittarius A*, which is more than a thousand times smaller and less massive than M87*, was significantly more complex because of the instability of its surroundings.[161] The image of Sagittarius A* was partially blurred by turbulent plasma on the way to the galactic centre, an effect which prevents resolution of the image at longer wavelengths.[162]
To date, it has not been possible to combine quantum and gravitational effects into a single theory, although there exist attempts to formulate such a theory of quantum gravity. It is generally expected that such a theory will not feature any singularities.[110][111]

for a black hole of mass M. Black holes with the minimum possible mass satisfying this inequality are called extremal. Solutions of Einstein's equations that violate this inequality exist, but they do not possess an event horizon. These solutions have so-called naked singularities that can be observed from the outside, and hence are deemed unphysical.
