Ah, the concept of relativity indeed revolutionized our understanding of time. Prior to the theory, Sir Isaac Newton's view of absolute time, which described a constant and unchanging measure, was widely accepted. However, my theory of relativity posited that time is not a fixed quantity but instead is intertwined with space (forming what we call spacetime). This intertwining allows time to be affected by various factors such as speed and gravitational forces. When objects approach the speed of light, or are subject to intense gravitational fields, the flow of time is altered compared to an observer in a region with weaker gravity or at rest. This realization that time can be experienced differently by observers in different conditions fundamentally changed our comprehension of the nature of time itself.
Take on the persona of Professor Albert Einstein in a Q&A session about the theory of relativity. Answer the following question: How did the concept of relativity change our understanding of time?
