Since it is practically impossible to artificially create a perfect sphere, are black holes the closest thing?
I believe they are, but better to let one of the experts here clarify it.Alanay said:Since it is practically impossible to artificially create a perfect sphere, are black holes the closest thing?
Yeah I believe the OP is talking about the event horizon.lifeonmercury said:My understanding is that a black hole is a singularity but the borders of the event horizon surrounding it form a perfect sphere.
So just to build off of this, would a faster rotation speed of the BH lead to a more elongated black hole (along its axis)?Vanadium 50 said:If the black hole is rotating, the EH is axially, not spherically symmetric.
I think it's more disk-like, not more elongated along the axis.Comeback City said:So just to build off of this, would a faster rotation speed of the BH lead to a more elongated black hole (along its axis)?
But is it the ergosphere that is disk-like, or the event horizon itself?phinds said:I think it's more disk-like, not more elongated along the axis.
Aaargh ... frame dragging, that really gets on my nerves.Comeback City said:But is it the ergosphere that is disk-like, or the event horizon itself?
AAAARGH! I'm sorry for my pitiful questionrootone said:Aaargh ... frame dragging, that really gets on my nerves.

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. It is formed when a massive star dies and collapses in on itself.
According to Einstein's theory of general relativity, black holes are predicted to be perfect spheres due to the uniformity of their gravitational pull. However, factors such as rotation and the presence of matter can cause slight distortions.
Black holes cannot be directly observed, so their properties are inferred through their effects on surrounding matter and light. Scientists use telescopes and advanced mathematical models to study these effects and estimate the size and mass of a black hole.
No, the shape of a black hole can vary depending on its size and rotation. Smaller black holes tend to be more spherical, while larger ones can be more oblong. They can also have different shapes if they are influenced by the gravitational pull of nearby objects.
Perfect spheres are rare in the universe, as they require a uniform distribution of mass and rotation. While black holes are close to being perfect spheres, they are not entirely so due to the factors mentioned above. The closest thing to a perfect sphere in the universe is probably a neutron star.
