Space-time is a fundamental concept in modern physics, central to Einstein’s theory of relativity. It combines the three dimensions of space with the one dimension of time into a four-dimensional continuum. This unified model helps explain how gravity works and how objects move through the universe. In relativity, space and time are not separate entities but are interwoven into a single fabric. Massive objects, like stars and planets, cause this fabric to curve, and this curvature is what we per

Space conceals a secret structure called spacetime -- a tangible substance that bends, stretches, warps and twists matter into the stars and planets we see around us. In many ways, we're just going along for the ride 😎 Stream How The Universe Works on Discovery #ScienceChannel #HowTheUniverseWorks | Science Channel
