A black hole has infinite density.
It is infinite
It's only infinite around the event horizon.
There is no way to escape from a black hole because it's gravity is infinite.
The gravity in a black hole is so strong that not even light can escape. For all intents and purposes it can be considered infinite.
The classical idea about black holes is that in a black hole, mass is concentrated to an infinitely small size, so it has an infinite density. That would cause an infinite gravitational field. However, this infinite density, etc. seems doubtful in view of quantum physics - but what exactly happens near the center of a black hole has not been completely clarified yet.
It is not known what happens to matter inside a black hole. The point of origin of the universe is currently believed to be the Big Bang, which is different from a black hole. The gravitational pull of a black hole is so strong that matter is compressed to a point of infinite density at the singularity, according to general relativity.
In the center of a black hole is a region of spacetime called a singularity, a dimensionless point of infinite density, infinite gravity and infinite space time curvature, where the familiar physical laws of the universe no longer seem to apply, and counter-intuitive effects may be apparent, like the complete stoppage of time itself.
The gravity is enormous! The gravity in a black hole is high enough to stop light escaping.
Yes, there's gravity in a black hole.. gravitational force is exerted wherever there is mass.
You bet they do! Black holes can have only three properties:mass - this creates the gravitational pull and is a property of every black holespin - this will likely be a property of any stellar black hole as all stars spincharge - this will be a rare property as it will attract opposite charge and soon be canceled
A black hole is created when a massive star collapses under its own gravity, causing its core to condense into a point of infinite density called a singularity. This creates a region of spacetime where gravity is so strong that nothing, not even light, can escape its pull.
Einstein's theory of the fabric of space that each planet has its own gravity that makes an indention the fabric of space depending on the amount of gravity, well a black hole is an infinite indention.
