Meanings
noun

时空，四维时空。

The four-dimensional continuum of the three spatial dimensions plus time.

Examples :

noun

时空，四维时空。

An n-dimensional continuum consisting of dimensions of both space and time. Normally spacetime is considered as having 4 dimensions (x, y, z, t), but higher-dimensional spacetimes are often encountered in theoretical physics, e.g. the 5-dimensional spacetime of Kaluza-Klein theory or the 11 dimensions of spacetime in M-theory.

Examples :

"Scientists study spacetime to understand how gravity affects the universe. "
科学家研究时空，以便理解引力如何影响宇宙。
