Albert Einstein united space and time in one mathematical description with his theory of general relativity (1915). https://www.britannica.com/science/relativity
Physical space is often conceived in three linear dimensions. Most modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as space-time. https://en.wikipedia.org/wiki/Space
General relativity is concerned with gravity, one of the fundamental forces in the universe. Gravity is treated as a geometric phenomenon that arises from the curvature of space-time. https://www.britannica.com/science/general-relativity
