Temporal mechanics is a branch of physics that studies the nature of time and its relationship with space and matter. It explores how time can be perceived differently under various conditions, such as in the presence of strong gravitational fields or at high speeds, as described by Albert Einstein's theory of relativity. This field also examines concepts like time travel and the possibility of altering past events. While often popularized in science fiction, temporal mechanics raises important questions about causality and the structure of the universe, influencing both theoretical physics and philosophical discussions about the nature of reality.
