None that is known. All of the mass in a black hole is contained in an infinitely dense point. At this point the laws of physics as we understand them break down. The nature of the singularity is unknown.
No. The only force at work with a black hole is gravity.
What medium and temperature as there is something called "pressure temperature relationship"
The inward force of gravity is counteracted by two outward forces: gas pressure, and radiation pressure. Once the star runs out of fuel, the radiation pressure stops, the gas pressure is no longer enough to counteract gravity, and the star collapses - into a white dwarf, a neutron star, or a black hole, depending on its mass.
The core contracts and becomes a black hole.

It is first stretched then pressurised. so if a human was to enter a black hole, you would first be turned into a spaghetti-looking thing then you will be pressureised. too much pressure on any human will make them explode.
When the gravity of a neutron star overcomes the degeneracy pressure of the neutrons, the neutron star collapses into a black hole.
The pressure within a protostar counters gravity and prevents the star from collapsing further.
if they are black all the sterotypes are true
actually black holes are the masters of gravity has the most gravity ever
There is no relationship between genital size and race.
Most Black Holes are created when a star that has 20 times the mass of our sun dies. In a stars life there is a constant war between pressure pushing out and gravity pulling in and when it dies it the outer part is thrown into space and the inner core collapses into itself, creating a black hole.
