What is the shape of a black hole?

Answer 1

There is no true shape.

Despite having no shape and being infinitely small—smaller than an atom—the region that is affected by black holes' gravity is round because of their uniform gravitational pull in all directions.

Answer 2

Black holes are spherical.

A black hole is defined by its event horizon. This is defined to be the Schwarzschild radius #r_s#.
#r_s = (2GM)/c^2#
Where #G# is the gravitational constant, #M# is the mass of the black hole and #c# is the speed of light.

There is no way out of the event horizon.

Thus, the black hole's spherical shape is indicated.

If the black hole is spinning, the Schwarzschild solution to Einstein's field equations assumes that it is not, in which case its shape would be that of a slightly flattened sphere.

Answer 3

Generally speaking, the shape of a black hole is defined as a singularity, which is an infinitely dense point at the center encircled by an event horizon—a boundary beyond which nothing—not even light—can escape.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
