<prompt> Hlalosa ka polelo e le ngoe mohopolo oa khopolo e akaretsang ea Einstein ea kamano.nan  <response>: Instruction in English: Explain in one sentence the concept of Einsteins general theory of relativity. . Response in English: Einsteins general theory of relativity proposes that massive objects cause a curvature in spacetime, resulting in the observed gravitational attraction between masses, which is described using the geometry of a four-dimensional, pseudo-Riemannian manifold representing spacetime, rather than the force of gravity. . Response in Sesotho: Khopolo-kakaretso ea Einstein ea kamano e fana ka maikutlo a hore lintho tse kholo li baka ho kobeha ha nako ea sepaka-paka, e leng se bakang khoheli e bonoang pakeng tsa bongata, e hlalosoang ho sebelisoa geometry ea mahlakore a mane, manifold a pseudo-Riemannian a emelang nako ea sepaka-paka, ho e-na le matla a khoheli.
