Is infinite density possible?
Infinite density can’t exist because infinity anything generally implies a breakdown of the theory.
Does the center of a black hole have infinite density?
The density at the center of a black hole is infinite (it’s a famous “singularity”, which leads to difficulties in modern cosmology).
How does black hole density depend on the mass of the black hole?
Black holes can be low density. Of all the weirdnesses about black holes, this one is the weirdest to me. As you might expect, the event horizon of a black hole gets bigger as the mass gets bigger. That’s because if you add mass, the gravity gets stronger, which means the event horizon will grow.
Why are black holes infinitely dense?
A black hole has an infinite density; since its volume is zero, it is compressed to the very limit. So it also has infinite gravity, and sucks anything which is near it!
Does infinite density mean infinite mass?
If something is infinitely dense, must it not also be infinitely massive? Nope. The singularity is a point where volume goes to zero, not where mass goes to infinity. It is a point with zero volume, but which still holds mass, due to the extreme stretching of space by gravity.
What is meant by infinite density?
Infinite density would imply that the entire matter in question is concentrated at a geometrical and dimensionless point.
What is the density of a black hole?
The answer – as you probably expect at this point – is that there is no set density for a black hole to form. Instead of depending on the mass per volume (A.K.A. density) of an object, black hole formation depends on the mass per radius of an object.
Can neutron degenerate matter be converted into a black hole?
Well yes, but it still doesn’t help. Eventually, after a lot of compression, the neutron degenerate matter will collapse into a black hole. What density does that happen at? The answer – as you probably expect at this point – is that there is no set density for a black hole to form.
How does something become a black hole?
For something with the mass of the earth to become a black hole it needs to be compressed down to about 1.8 centimeters in diameter – which is extremely dense. Something the mass of a whole galaxy on the other hand will become a black hole if compressed into a space about half a lightyear wide, giving a density significantly less than that of air!
Why is the density of space-time so high?
Many physicists think that this represents the highest density for any natural compression mechanism, because at higher densities, space-time itself transmutes into some type of quantum mechanical system for which ‘density’ is not a meaningful concept.
