Gullstrand coordinates” for a foliation of a spherically sym-metric spacetime with ﬂat spatial sections: this is an essen-tial feature of these coordinates that we want to preserve.

The Gullstrand-Painlevé tetrad free-falls through the coordinates at the Newtonian escape velocity. To describe the dynamics of collapse, we use a generalized form of the Painlevé-Gullstrand coordinates in the Schwarzschild spacetime. The time coordinate of the form is the proper time of a free-falling observer so that we can describe the collapsing star not only outside but also inside the event horizon in a single coordinate patch. The continuation of the Schwarzschild metric across the event horizon is a well-understood problem discussed in most textbooks on general relativity.

As the raindrop plunges toward the black hold, the speed increases. At the event horizon, the speed has the value 1, same as the speed of light. recently been introduced by Albert Einstein. In 1921, Painleve proposed the Gullstrand Painleve coordinates for the Schwarzschild metric.

19 Jul 2010 Painlevé–Gullstrand (PG) coordinate system, the metric is not diagonal, but recovers the extended Schwarzschild metric in PG coordinates,

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?). This section also needs a reference since Wikipedia is not supposed to be original research. 24.84.125.240 10:24, 23 November 2013 (UTC) 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 describ Painlev´e-Gullstrand coordinates The line element for the unique spherically symmetric, vacuum solution to the Einstein equation can be written as ds2 = dT 2−(dr + s 2M r dT) −r2dΩ2 (1) Note that a surface of constant T is a ﬂat Euclidean space.
