Topological illustration of spacetime dilation: which function should I use for isometric lines spacing?
Scientific popularization, when it comes to illustrating spacetime dilation around massive objects, often relies on the description of a two-dimensional square-grid, which can be regarded as a cross-...

Einstein field equations (EFE) $N$-body simulator
I made a $N$-body simulator and it works well, but it uses Newton's gravitational equation, which is nice, but I want it to simulate Einstein field equations. Speed of gravity should be simple enough, ...

$N$-body simulation in General Relativity
How would one perform an $N$-body simulation in General Relativity (GR) for something like galaxy formation or galactic dynamics?
Suppose one wants to simulate the rotation curve $v(r)$ for galaxies ...
