What did Albert Einstein say about the connection between space and time?

Albert Einstein revolutionized the understanding of space and time through his theory of relativity, proposing that they are interwoven into a single continuum known as spacetime. He suggested that the fabric of spacetime is affected by mass and energy, leading to the phenomenon of gravity. This means that the presence of mass can warp spacetime, influencing the motion of objects and the passage of time itself. In essence, Einstein showed that time and space are not separate entities but are deeply interconnected.
