he concept of time dilation, a phenomenon predicted by Einstein's theory of relativity, posits that time can elapse at different rates depending on the gravitational field and relative velocity. This means that time can appear to move slower or faster for observers in different conditions. Such a revelation challenges our intuitive understanding of time as a constant and universal force. While time travel remains a theoretical construct and has not been realized in practice, scientific exploration has brought us closer to understanding the fundamental nature of time.
