Web14 de nov. de 2024 · In three-dimensional de Sitter space classical black holes do not exist, and the Schwarzschild-de Sitter solution instead describes a conical defect with a single cosmological horizon. We argue that the quantum backreaction of conformal fields can generate a black hole horizon, leading to a three-dimensional quantum de Sitter …

Numerical results of the dimensionless ratio η can be seen in Table 1 and Table 2.We can observe that the dimensionless ratio η ≫ 1 for the five-dimensional black hole (regardless of the cases of q = 10, 20, and 40 in Table 1, in which the mass of the black hole is … Web16 de nov. de 2015 · With this equation we can see immediately that a black hole with the same mass as the Sun would have the (enormously high) density of $1.85 \times 10^{19}$ kg/m$^3$. Alternatively, a super supermassive black hole with the mass of 4.3 billion Suns would have a density equal to one i.e. the same density as water.
