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 occur.
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. Einstein's theories of relativity spurred other scientists to investigate the relationships between space ...
Dec 29, 2023 · Spacetime is warped by large masses in ways we experience as gravity. The “space-time continuum” is one of the concepts that came out of relativity theory that most people have heard of, but ...

17–1 The geometry of space-time. The theory of relativity shows us that the relationships of positions and times as measured in one coordinate system and another are not what we would have expected on the basis of our intuitive ideas. It is very important that we thoroughly understand the relations of space and time implied by the Lorentz ...

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. In his famous quotation delivered at a public lecture on relativity, he announced that,
\"The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.\"
This new reality was that space and time, as physical constructs, have to be combined into a new mathematical/physical entity called 'space-time', because the equations of relativity show that both the space and time coordinates of any event must get mixed together by the mathematics, in order to accurately describe what we see. Because space consi...
Learn what a space-time continuum is and how it relates to relativity theory. Find out how space and time are combined into a 4-dimensional object and how events are described in terms of their location in space-time.
Learn what spacetime is and how it relates space and time in physics. Explore how spacetime varies for different observers, how it is measured, and how it is bent by gravity.
