It is not possible for time to stop. Time is a fundamental aspect of the universe and is connected to the concept of change and the flow of events. Without time, it is not clear how the universe would function or how events would unfold. The laws of physics, as we understand them, rely on the passage of time and would break down if time were to stop. However, it is possible to slow down time or to experience time differently under certain conditions. For example, time appears to pass more slowly for objects moving at very high speeds or for objects in strong gravitational fields. This phenomenon, known as time dilation, is a result of the relativistic effects predicted by the theory of relativity. However, this does not mean that time has actually stopped; it just means that the rate at which time passes appears to be different from an outside observer.
