time-space
Einstein's unified framework
Time-space is the unified framework in which all physical events occur—three dimensions of space plus one of time, treated as a single continuum.
Einstein's relativity showed that time and space aren't separate absolutes but interconnected aspects of the same fabric.
Also called spacetime.
In geography and social science, time-space describes how distance and duration interact: Time-space compression has made the world feel smaller.
