A moving medium simulation of Schwarzschild black hole optics | | Kjell Rosquist
; | | Date: |
22 Sep 2003 | | Journal: | Gen.Rel.Grav. 36 (2004) 1977-1982 | | Subject: | gr-qc | | Abstract: | An explicit fluid flow simulation of electromagnetic wave propagation in the gravitational field of a Schwarzschild black hole is given. The fluid has a constant refractive index and a spherically symmetric inward directed flow. The resulting form of the metric leads to a new coordinate system in which the Schwarzschild vacuum is written in Gordon’s form. It is shown that a closely related coordinate system interpolates between the Kerr-Schild and Painleve-Gullstrand coordinates. | | Source: | arXiv, gr-qc/0309104 | | Services: | Forum | Review | PDF | Favorites | |
