We follow the original work by Oppenheimer and Snyder, starting from the general spherically symmetric metric in comoving coordinates. Further, a rederivation of the work by Chen, Adler, Bjorken and Liu shows that the same results can be obtained using the Friedmann-Robertson-Walker metric, with the curvature constant set to zero, and using Gullstrand-Painlev ́e coordinates.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We construct a coordinate system for the Kerr solution, based on the zero angular momentum observers dropped from infinity, which generalizes the Painlevé-Gullstrand coordinate system for the Schwarzschild solution. The Kerr metric can then be interpreted as describing space flowing on a (curved) Riemannian 3-manifod.
The function f Gullstrand-Painleve Coordinates First and foremost, the Gullstrand-Painlevé coordinates are not an independent solution of Einstein’s field equation, but rather an adjustment of the Schwarzschild solution to a different coordinate reference, such that the apparent coordinate singularity at [r=Rs] is avoided. Gullstrand–Painlevé coordinates are a particular set of coordinates for the Schwarzschild metric – a solution to the Einstein field equations which describes a black hole. The ingoing coordinates are such that the time coordinate follows the proper time of a free-falling observer who starts from far away at zero velocity, and the spatial slices are flat. Gullstrand–Painlevé coordinates are a particular set of coordinates for the Schwarzschild metric – a solution to the Einstein field equations which describes a black hole.

Painlevé–Gullstrand coordinates, a very useful tool in spherical horizon thermodynamics, fail in anti-de Sitter space and in the inner region of Reissner–Nordström. We predict this breakdown to occur in any region containing negative Misner–Sharp–Hernandez quasilocal mass because of repulsive gravity stopping the motion of PG observers, which are in radial free fall with zero initial

The speed of the raindrop is inversely proportional to the square root of radius. At places very far away from the black hole, the speed is extremely small.

The ingoing coordinates are such that the time coordinate follows the proper time of a free-falling observer who starts from far away at zero velocity, and the spatial slices are flat. There is no coordinate singularity Gullstrand–Painlevé coordinates: | |Gullstrand–Painlevé coordinates| are a particular set of coordinates for the |Schwarzsch World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled. A known set of coordinates used for the Schwarzschild metric is the Painlevé-Gullstrand coordinates. They consist in performing a change from coordinate time t to the proper time T of radially infalling observers coming from infinity at rest. The transformation … 2019-04-25 2016-12-18 It really does not have anything to do with the Gullstrand-Painleve coordinates. (Why is Gullstrand's name first since his paper was published later?).
