t. e. In physics, spacetime 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.
31. März 2024 · Space-time, in physical science, single concept that recognizes the union of space and time, first proposed by the mathematician Hermann Minkowski in 1908 as a way to reformulate Albert Einstein’s special theory of relativity (1905). Learn more about space-time in this article.

Raumzeit (engl. space-time) ist ein Kunstwort, dass angemessen ein wesentliches Resultat der Relativitätstheorie ausdrückt: Raum und Zeit sind keine Dimensionen mehr, die unabhängig voneinander sind. Wie die Lorentz-Transformation der Speziellen Relativitätstheorie (SRT) zeigt, bilden Raum und Zeit ein Kontinuum!

The famous physicist Albert Einstein helped develop the idea of space-time as part of his theory of relativity. Prior to his pioneering work, scientists had two separate theories to explain physical phenomena: Isaac Newton's laws of physics described the motion of massive objects, while James Clerk Maxwell's electromagnetic models explained the pro...
Nowadays, when people talk about space-time, they often describe it as resembling a sheet of rubber. This, too, comes from Einstein, who realized as he developed his theory of general relativity that the force of gravitywas due to curves in the fabric of space-time. Massive objects — like the Earth, sun or you — create distortions in space-time tha...
Despite its intricacy, relativity remains the best way to account for the physical phenomena we know about. Yet scientists know that their models are incomplete because relativity is still not fully reconciled with quantum mechanics, which explains the properties of subatomic particles with extreme precision but does not incorporate the force of gr...

In physics, spacetime is any mathematical model that combines space and time into a single continuum. It is a mathematical concept used to refer to all points of space and time and their relation to each other. Historically, space and time were thought of as separate entities.
Spacetime or space–time is a mathematical model that joins space and time into a single idea called a continuum. This four-dimensional continuum is known as Minkowski space. Combining these two ideas helped cosmology to understand how the universe works on the big level (e.g. galaxies) and small level (e.g. atoms ).
