Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime.
Definition[edit | edit source]
In mathematics, "space" is a set (sometimes called a universe) with some added structure. While modern physics uses concepts such as space-time to understand the universe, philosophical discussions of space often focus on questions about its nature and whether it is truly infinite.
