How small is the singularity of a black hole?

How small is the singularity of a black hole?

The discreteness of space-time prevents matter from reaching anything smaller than the Planck length (around 1.68 times 10^-35 meters, so… small). All the material that has ever fallen into the black hole gets compressed into a ball not much bigger than this. Perfectly microscopic, but definitely not infinitely tiny.

Are all singularities the same?

Not all singularities are the same size – for instance, the singularity in the big bang is infinite in extent. The singularity in a rotating black hole is a ring. In physics, the word “singularity” just means “here is a bit of our equations that does not make sense so it’s probably wrong”.

What is a small singularity?

In the center of a black hole is a gravitational singularity, a one-dimensional point which contains a huge mass in an infinitely small space, where density and gravity become infinite and space-time curves infinitely, and where the laws of physics as we know them cease to operate.

Why are black holes called singularities?

In the real universe, no black holes contain singularities. In general, singularities are the non-physical mathematical result of a flawed physical theory. A singularity is a point in space where there is a mass with infinite density. This would lead to a spacetime with an infinite curvature.

Does black hole contain singularity?

In the real universe, no black holes contain singularities. In general, singularities are the non-physical mathematical result of a flawed physical theory. A singularity is a point in space where there is a mass with infinite density.

Is black hole infinitely small?

Black holes are singularities: points of infinitely small volume with infinite density. Such incredibly compact objects cause infinite curvature in the fabric of spacetime. Everything that falls into a black hole is sucked toward the singularity.

Is a black hole singularity smaller than a Planck length?

This creates an outward force known as quantum-gravitational pressure, and if true, it means that black holes don’t have singularities at their core. They are many times larger than the Planck length, but are still unimaginably dense, but not infinitely dense like a singularity.
