Time in Physics

Time in physics is a fundamental dimension that orders events from past to future. It provides a framework to measure change, duration, and the sequence of occurrences. In classical physics, time flows uniformly, acting as a backdrop for physical processes. However, in modern physics, especially relativity, time is intertwined with space, forming spacetime, where it can stretch or contract depending on gravitational fields and relative motion. Despite its abstract nature, time helps us understand the universe’s evolution, movement, and causality, serving as an essential concept for describing how the physical world changes and progresses.
