In the Wiki article about the Vaidya metric :

http://en.wikipedia.org/wiki/Vaidya_metric

there is mention of a "further generalisation" called the Kinnersley metric, without giving any details or even a reference. Is this a generalisation of the Vaidya metric to include angular momentum ( i.e. a radiating Kerr or Kerr-Newman solution ), or is it something different ? Does anyone have a link to the specific form of the Kinnersley metric ?

I am really just curious, and somewhat disappointed about the poor quality of this particular Wiki page, and its lack of referenced sources.

The metric is known as Kinnersley's relativistic rocket. You can easily google it.
 
The Kinnersley photon rocket. Got it, and will do my own research into it. Thank you :)
 
See the interesting discussion in section 19.5.2 "Kinnersley's rocket" from the excellent book "Exact Space-Times in Einstein's General Relativity" by Jerry B. Griffits and Jiri Podolsky.

If ##\alpha = 0##, the metric (19.54) reduces to the Vaidya–(anti-)de Sitter spacetime
expressed in the form (19.51).
 
Thank you George Jones for the reference - unfortunately I do not own a copy of this text, but I will see what I can do to track down this book at a reasonable cost. Seems like a worthwhile investment !
 
Thread 'Can this experiment break Lorentz symmetry?'
1. The Big Idea: According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box. 2. How It Works: The Two-Stage Process Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...

Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy. Experiment design: Place two identical clocks A and B on the circumference of a wheel at opposite ends of the diameter of length L. The wheel is positioned upright, i.e., perpendicular to the ground...
