Space-time duality

Space and time are dual concepts. They are complementary to one another as an inverse binary symmetry. They go together as space with time in classical physics or time with space or spacetime as in relativistic physics.

Parallel terms:

Space Time
3D space +reference time 3D time + reference length
vector space + scalar time vector time + scalar space
spatiocosm tempocosm
reference frame reference timeframe
space position time position
particle tempicle
body (an object) body, somebody (a subject)
waypoint instant
clock odometer
