Spacetime - Wikipedia
In physics, spacetime, also called 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 ...
What Is the Space-Time Continuum? - Wonderopolis
The space-time continuum consists of four dimensions: the three dimensions of space (length, width, and height…or up/down, left/right, and forward/backward, depending upon how you wish to think of them) plus the fourth dimension of time.

2022年11月14日 · The arena of special relativity is today known as Minkowski space-time. Once you have the idea of thinking of space-time as a unified four-dimensional continuum, you can start asking questions about its shape. Is space-time flat or curved, static or dynamic, finite or infinite? Minkowski space-time is flat, static and infinite.

Special & General Relativity Questions and Answers
What is a space time continuum? In 1906, soon after Albert Einstein announced his special theory of relativity, his former college teacher in mathematics, Hermann Minkowski, developed a new scheme for thinking about space and time that emphasized its geometric qualities.
17 Space-Time - The Feynman Lectures on Physics
This new world, this geometrical entity in which the “blobs” exist by occupying position and taking up a certain amount of time, is called space-time. A given point $(x,y,z,t)$ in space-time is called an event. Imagine, for example, that we plot the $x$-positions horizontally, $y$ and $z$ in two other directions, both mutually at “right ...
What Is The Space-Time Continuum? - IFLScience
2023年12月29日 · What Is The Space-Time Continuum? We experience space and time as quite separate, but thinking about conditions close to the speed of light reveals the necessity to connect them.
continuum is curved and the amount of curvature in a region encodes the strength of the gravitational field there. Space-time is not an inert entity. It acts on matter and can be acted upon. As the American physicist John Wheeler puts it: Matter tells space-time how to bend and space-time tells matter how to move.
