Time-Space Continuum

The time-space continuum is a four-dimensional framework combining the three dimensions of space (up/down, left/right, forward/backward) with time as the fourth dimension. It describes how objects move and interact within the universe, emphasizing that space and time are interconnected rather than separate. Gravity, for example, is understood as the warping or curvature of this continuum caused by mass and energy, which affects the motion of planets and light. This concept helps explain phenomena like why planets orbit stars and how gravity influences the path of light across the cosmos.
