Gold Member. 748. 41. While I understand Doran coordinates and Doran form (Gullstrand-Painlevé form at a=0), I'm not entirely convinced with Gullstrand-Painlevé coordinates. While the Doran time coordinate ( t ¯) is expressed-. d t ¯ = d t + β 1 − β 2 d r.
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 Gullstrand-Painlevé tetrad free-falls through the coordinates at the Newtonian escape velocity. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We derive the exact equations of motion (in Newtonian, F = ma, form) for test masses in Schwarzschild and Gullstrand-Painlevé 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.
While the Doran time coordinate ( t ¯) is expressed-. d t ¯ = d t + β 1 − β 2 d r. where. At the end of part 1, we looked at the form the metric of the Schwarzschild geometry takes in Gullstrand-Painleve coordinates: ds^2 = – \left( 1 – \frac{2M}{r} \right) dT^2 + 2 \sqrt{\frac{2M}{r}} dT dr + dr^2 + r^2 \left( d\theta^2 + \sin^2 \theta d\phi^2 \right) It really does not have anything to do with the Gullstrand-Painleve coordinates.

La derivazione delle coordinate di GP richiede di definire i sistemi di quelle successive e di capire come Coordinate di In GP coordinates, the velocity is given by. The speed of the raindrop is inversely proportional to the square root of radius.
There are a few choices of these types of coordinates with the most common being the Gullstrand-Painleve coordinates. If we take the Schwarzschild metric.

At the end of part 1, we looked at the form the metric of the Schwarzschild geometry takes in Gullstrand-Painleve coordinates: ds^2 = – \left( 1 – \frac{2M}{r} \right) dT^2 + 2 \sqrt{\frac{2M}{r}} dT dr + dr^2 + r^2 \left( d\theta^2 + \sin^2 \theta d\phi^2 \right) It really does not have anything to do with the Gullstrand-Painleve coordinates.

In GP coordinates, the velocity is given by. 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.
Famous quotes containing the words speeds and/or light: “ An honest tale speeds best being plainly told.
The continuation of the Schwarzschild metric across the event horizon is a well-understood problem discussed in most textbooks on general relativity. Among the most popular coordinate systems that are regular at the horizon are the Kruskal–Szekeres and Eddington–Finkelstein coordinates. Our first objective in this paper is to popularize another set of coordinates, the Painleve–Gullstrand Gullstrand – Painlevé -koordinaatit ovat erityinen koordinaatisto Schwarzschild-metriikalle - ratkaisu Einstein-kentän yhtälöihin, joka kuvaa mustaa aukkoa. .
