spacetime
Meanings
시공간
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. "
과학자들은 중력이 우주에 어떤 영향을 미치는지 이해하기 위해 시공간을 연구합니다.
시공간 영역
A specific region of the universe with mathematically different properties than the surrounding spacetime. Synonymous with "metric" within the context of general relativity.
