Albert Einstein's theory of relativity revolutionized our understanding of time. In his theory, Einstein defined time as a dimension closely intertwined with space, forming a four-dimensional framework known as spacetime. According to Einstein's theory, time is not an absolute quantity that flows uniformly for everyone, but rather a flexible and relative concept that depends on the observer's motion and gravitational field.
In a simple definition, Einstein's view of time can be summarized as follows: Time is not a fixed and universal ticking of a clock but a dynamic and malleable dimension that varies with motion and gravity. It is intricately linked to the three dimensions of space, forming a unified four-dimensional framework in which events occur and measurements are made.
