Jul 1, 2014 at 17:24 | comment | added | John Rennie | @StanLiou: I only chose the Schwarzschild metric because I could think of several coordinate systems for it. The FLRW metric would be a better example but as far as I know we only using comoving coordinates for this, or at least I've never seen a different coordinate system used. If you can think of a better example please shout! | |
Jul 1, 2014 at 17:22 | comment | added | Stan Liou | I feel that Schwarzschild geometry isn't a good example, because it is static, and hence there's a distinguished timelike direction, in this case Schwarzschild time. But the point certainly holds for most spacetimes. | |
