Spacetime

Mathematical model combining space and time.

space-time

Spacetime is a mathematical model that combines three-dimensional space and time into a single continuum. It is used in physics, particularly in the theory of relativity.

/ˈspeɪsˌtaɪm/

The term was coined by Hermann Minkowski in 1908, combining the concepts of space and time.

Spacetime is like a giant trampoline where heavy things, like planets, make dips that affect how other objects move around them.

Einstein's theory of relativity showed that gravity isn't a force, but a curvature in spacetime
Time passes differently depending on your speed and the strength of gravity
A black hole warps spacetime so much that nothing, not even light, can escape

What is spacetime? It's a mathematical model that combines the three dimensions of space with time
How did it develop? Albert Einstein's theory of relativity introduced the concept of spacetime
What does it describe? It describes how gravity works by warping space and time
