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 (talk) 10:24, 23 November 2013 (UTC) • The original Gullstrand-Painleve coordinates are for “rain”, e=1 • (Bonus: generalised Lemaitre coordinates) 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. Other very useful coordinates in the literature (e.g., those of [24] for the Reissner–Nordström spacetime) recast a spheri- "Gullstrand–Painlevé coordinates" are a particular set of coordinates for the Schwarzschild metric – a solution to the Einstein field equations which describ Abstract 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.

A chacteristic feature of PG coordinates is that the three-dimensional spatial sections of spacetimes foliated by these coordinates are ﬂat. PG coor-dinates constitute a very useful chart also in other problems 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. 1.

Figure 1: Simultaneity choices under various coordinates 1 Jun 2020 We find a specific coordinate system that goes from the Painlev\'e-Gullstrand partial extension to the Kruskal-Szekeres maximal extension and 27 Mar 2015 We transform this wave equation to usual Schwarzschild, Eddington-Finkelstein, Painlevé-.

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. 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.

Band 1 was selected as the Gullstrand-Painleve (rain e=1) T=const timelike Eddington-Finkelstein t=const.

The Kerr metric can then be interpreted as describing space flowing on a (curved) Riemannian 3-manifold. Famous quotes containing the words speeds and/or light: “ An honest tale speeds best being plainly told.

At the event horizon, the speed has the value 1, same as the speed of light. It is known that Painlev ´ e, Gullstrand and (some years later) Lema ˆ ıtre used a non-orthogonal curvature coordinate system which allows to extend the Sc hwarzsc hild solution inside its horizon, The boundary and gauge fixing conditions are chosen to be consistent with generalized Painleve-Gullstrand coordinates, in which the metric is regular across the black hole future horizon.
