Time is a fundamental concept describing the continuous progression of existence moving irreversibly from past through present into future. As a measurable dimension alongside space, time serves to sequence events, compare their duration, and quantify rates of change in both the physical world and human experience. Often termed the fourth dimension, time remains essential to understanding causality and the dynamics of all observable phenomena.
