Spacetime & temporal experience
Worldlines, proper time, simultaneity, and the relation between physical time and experienced succession.
A life in spacetime
A worldline places events in a temporal geometry. It helps us think beyond an isolated present without supplying a theory of the observer.
Clocks and lived duration
Relativistic time dilation makes elapsed time depend on a path through spacetime. It challenges a universal clock without proving an ontology.
The present and the limits of simultaneity
Relativity changes the physical meaning of a shared present. The metaphysical conclusions require a further argument.
