Clocks and Chronogeometry: Rotating Spacetimes and the Relativistic Null Hypothesis.
Recent work in the physics literature demonstrates that, in particular classes of rotating spacetimes, physical light rays in general do not traverse null geodesics. Having presented this result, we discuss its philosophical significance, both for the clock hypothesis (and, in particular, a recent p...
