Web27 Jun 2024 · I am assuming that the equations [1] dm/dr = 4πr2 ρ(r)[2] (1/2J) dJ/dr = (m+4πr3p)/(r(r-2m))[3] dp/dr = -(ρ+p)[(1/2J) dJ/dr) – (2(p-s)/r) ]are intended for a universe which may or may not be static. Is this correct? Now I’m beginning to wonder if you’ve even read the title of the article. What is the seventh word in it? WebThis equation is in many ways similar to the non-relativistic Newtonian gravity problem . If the effective potential has a minimum, the particle can oscillate around that minimum with energy moving back and forth between kinetic in the term and the effective potential.

WebThe simplest such solution is the Schwarzschild solution for a static, spherically symmetric spacetime. This corresponds to a non-rotating planet or star, and allows us to make comparisons with Newtonian gravity. While rotating solutions are more realistic, many novel features can be seen from the Schwarzschild solution. http://sro.sussex.ac.uk/id/eprint/102112/1/blackholeentropy_arxiv.pdf 動画 mb 大きく

"WebThe Schwarzschild solution is a special case of the Kerr solution (found in 1963) which represents the external field of a rotating black hole. This can be written as an instance of Eq. ( 4) with e=g=l=\Lambda=0 and it is usual to write a^2:=\gamma. The ratio of spin to mass (in geometrized units) is then a/m. " - Schwarzschild equation and gravity
