    Blackholes
In summary, there are 4 known solutions to Einstein field equations for black holes, two of which are rotating and not spherical - Kerr and Kerr-Newman black holes. The other two are static and spherical - Schwarzschild and Reissner-Nordstrom black holes. Each variant has one with no charge and one with charge. Rotating black holes are non-spherical.

An amount of material I have read recently refers (specifically) to the spherical case of black holes. Are there non-spherical black holes?

Regards,

Noel.

Thanks Chronos. Can I just confirm - rotating implies non-spherical, is that correct?

1. What is a non-spherical black hole?

A non-spherical black hole is a type of black hole that does not have a perfectly round shape. It can have an irregular or distorted shape due to factors such as rotation, accretion of matter, and interactions with other objects.

2. How do non-spherical black holes form?

Non-spherical black holes can form through a variety of processes. They can be formed from the collapse of a single, massive star, or they can be the result of the merger of two or more black holes. They can also be formed through the accretion of matter onto an existing black hole, which can cause it to become distorted.

3. Do non-spherical black holes exist in nature?

Yes, non-spherical black holes do exist in nature. In fact, most black holes are not perfectly spherical. The shape of a black hole depends on its mass, rotation, and interactions with other objects.

4. What are the implications of non-spherical black holes?

Non-spherical black holes have important implications for the study of gravity and general relativity. The distortions in their shape can affect the way they interact with matter and other objects, and can also impact the gravitational waves they produce.

5. How do scientists study non-spherical black holes?

Scientists study non-spherical black holes through a variety of methods, including observations of their effects on surrounding matter, measurements of their gravitational waves, and simulations using computer models. These methods allow scientists to better understand the properties and behavior of non-spherical black holes.
