Into the black hole
As written in my blog , black holes are ultimate sinks in the spacetime, and any information cannot escape beyond the event horizon of the black hole once dropped inside it. I want to open a bit what could be inside a black hole and emphasize that mentioned infinities do not describe the real world. By the "No Hair Theorem" a black hole has only three properties including mass, charge and angular momentum. When a particle drops to a black hole it has impact on these properties. For instance, a mass of the particle adds the mass of the black hole. However, the most of its information gets trapped in the event horizon, such as baryon number or polarization. As written in the previous blog , the event horizon encodes the maximum information density and entropy. The event horizon is a sphere which surface area is proportional to the mass of the black hole squared. If you were to double the mass, the surface area would get four times, and the occupied volume eight times larger. Th...
