Eddington-Finkelstein coordinates

In summary, Eddington-Finkelstein coordinates are a set of mathematical coordinates used to study the geometry of space-time around black holes, particularly near the event horizon. They are different from other coordinate systems in that they are curved and regular, and were independently developed by Arthur Eddington and David Finkelstein. These coordinates have played a significant role in understanding black holes and have been used in other areas of astrophysics and related fields.

Can anyone tell me the date and the journal of Eddington's original paper that suggested the new coordinate system to remove the Schwarzschild singularity? I understand it was in the 1920s.

Thanks.

Related to Eddington-Finkelstein coordinates

1. What are Eddington-Finkelstein coordinates?

Eddington-Finkelstein coordinates are a set of mathematical coordinates used in the study of black holes. They are useful for describing the geometry of space-time around a black hole, particularly near the event horizon.

2. How are Eddington-Finkelstein coordinates different from other coordinate systems?

Eddington-Finkelstein coordinates are different from other coordinate systems in that they are "curved" coordinates, meaning they take into account the curvature of space-time near a black hole. They also have the advantage of being "regular" coordinates, meaning they do not break down at the event horizon like other coordinate systems.

3. Who developed the Eddington-Finkelstein coordinates?

Eddington-Finkelstein coordinates were independently developed by British astrophysicist Arthur Eddington and German mathematician David Finkelstein in the early 20th century. They were both seeking a coordinate system that could accurately describe the space-time around a black hole.

4. What is the significance of Eddington-Finkelstein coordinates?

Eddington-Finkelstein coordinates have played a significant role in the study of black holes and their properties. They have helped scientists understand the behavior of matter and energy near the event horizon, as well as the effects of strong gravitational fields on light and other particles.

5. Are Eddington-Finkelstein coordinates used for anything other than black hole research?

While Eddington-Finkelstein coordinates were originally developed for the study of black holes, they have also been used in other areas of astrophysics, such as the study of neutron stars and other highly compact objects. They have also been applied to other fields, such as general relativity and cosmology, as a way to describe the curvature of space-time in certain scenarios.
