“…In general relativity, the geodesics of the common Schwarzschild [10,12], Reissner-Nordström [13], and Kerr [5,14] spacetime (as well as all axisymmetric and static black-hole geometries) are integrable, and there is no chaotic behavior in the geodesic motion of the particles [8]. Because the geodesic equations of particles are variably fractional and the dynamical system is accretive, researchers have concluded that geodesic motion is not the best way to detect chaos arising from black holes.…”
