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.
Black holes and rainbows are both phenomena related to light and gravity, but they are very different. Black holes are extremely dense objects with strong gravitational pull that can trap light, while rainbows are caused by the refraction and reflection of light in water droplets. In short, the relationship between a black hole and a rainbow is that they both involve light and gravity, but they are fundamentally distinct in nature.
Stephen Hawking worked on quantum gravity throughout his career, but one of his notable contributions was made in the 1970s, when he investigated the quantum effects near black holes and proposed theories to explain the relationship between quantum mechanics and 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.

Yes, black holes are an example of negative pressure. This is because they exert gravitational force so strong that nothing, not even light, can escape from them, creating a region of extreme gravitational pressure.
When the gravity of a massive star overcomes neutron degeneracy pressure, it can result in the star collapsing further to form a black hole. This occurs when the mass of the star is above a certain threshold known as the Tolman–Oppenheimer–Volkoff limit, causing the neutron degeneracy pressure to be insufficient to support the star against gravity.
The relationship between the mass of a black hole and its density is that as the mass of a black hole increases, its density also increases. This means that a black hole with a higher mass will have a higher density compared to a black hole with a lower mass.
The pressure within a protostar counters gravity and prevents the star from collapsing further.
When the gravity of a massive star overcomes neutron degeneracy pressure, the core collapses under its own gravity, leading to the formation of a black hole or a neutron star, depending on the initial mass of the star. This process releases a tremendous amount of energy in the form of a supernova explosion.
Vacuum energy is a concept in quantum physics that suggests empty space is not truly empty but contains energy. Black holes, on the other hand, are regions in space where gravity is so strong that nothing, not even light, can escape. The relationship between vacuum energy and black holes is complex and not fully understood, but some theories suggest that vacuum energy may play a role in the behavior of black holes, influencing their formation and properties.
