But this is a somewhat different issue to that raised in your question. As for the mathematical characteristics which determine whether there is a 'preferred reference frame', I'm not sure, because I'm not sure how precisely to interpret 'preferred reference frame' in general. | |
| Nov 20, 2012 at 10:05 | comment | added | vonjd | Thank you, Rhys. How about my first two questions? Which (mathematical) characteristics determine whether there is a preferred reference frame in a universe? Does our universe have a preferred reference frame? Thank you again. | |
