What “spacetime” means
Wiktionary · Wikipediaspacetime
- nounThe four-dimensional continuum of the three spatial dimensions plus time.
In physics, spacetime, or the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events occur.
