Spacetime Continuum

The spacetime continuum is a concept in physics that combines space and time into a single four-dimensional framework. Instead of thinking of space and time as separate entities, it considers them interconnected, meaning that events are described by their position in both space (x, y, z) and time (t). This idea is fundamental to Einstein's theory of relativity, which explains how gravity affects the fabric of spacetime. When massive objects, like planets, are present, they warp spacetime, affecting the motion of other objects and the passage of time, leading to phenomena like time dilation.
