What is the composition of the black hole?

The basic structure of a black hole consists of a singularity hidden by an event horizon. Within the event horizon, the escape speed ( vesc ) exceeds the speed of light ( c ) and an object is trapped forever. Outside the event horizon, vesc < c and the object is able to escape.

What is the core of a black hole?

Singularity
Singularity. At the center of a black hole, as described by general relativity, may lie a gravitational singularity, a region where the spacetime curvature becomes infinite.

Can a black hole not have a 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. This would lead to a spacetime with an infinite curvature.

Are there molecules in a black hole?

For example, a team of researchers has shown that a special kind of particle can exist around a pair of black holes in a similar way as an electron can exist around a pair of hydrogen atoms — the first example of a “gravitational molecule.” This strange object may give us hints to the identity of dark matter and the …

Are there electrons in a black hole?

There is no evidence that the electron is a black hole (or naked singularity). Furthermore, since the electron is quantum mechanical in nature, any description purely in terms of general relativity is inadequate. Hence, the existence of a black hole electron remains strictly hypothetical.

What is a singularity in a black hole?

A singularity is simply the name for the collapsed core of the black hole. The event horizon is an imaginary sphere surrounding the black hole and is also defined as the opening of the black hole. Rotating black holes are referred to as Kerr black holes.

What are the different types of black holes?

The first classification of black holes has to do with whether they are rotating or not. Non-rotating black holes are called Schwarzschild black holes. These black holes have non-rotating cores and they have two main properties: a singularity and an event horizon.

What is a stellar mass black hole and how does it form?

Stellar mass black holes form when a star with a mass greater than three times that of our sun runs out of fuel. It explodes into a supernova and collapses into an extremely dense core that we know as a black hole — something predicted by Albert Einstein’s general theory of relativity.

What happens to light when it enters a black hole?

There’s a boundary at the edge of a black hole called the event horizon, which is the point of no return — any light or matter that crosses that boundary is sucked into the black hole. It would need to travel faster than the speed of light to escape, which is impossible.
