The meaning of SPACE-TIME is a system of one temporal and three spatial coordinates by which any physical object or event can be located —called also space-time continuum.

Einstein ’s former mathematics professor, Hermann Minkowski, was perhaps the first to note this effect (and perhaps understood it even better than Einstein himself), and it was he who coined …

Space-time is a concept that combines the three dimensions of space with the fourth dimension of time, creating a single, unified entity known as the “fabric of the universe.”

Key Takeaways on What Space-Time Is Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity.

We all travel in time! We travel one year in time between birthdays, for example. And we are all traveling in time at approximately the same speed: 1 second per second.
