The concept of time is deeply intertwined with the concept of change. Change is often understood as the transition from one state to another over a period of time. Without the existence of time, it becomes difficult to conceive of change in the conventional sense.
However, it is important to note that discussions about the nature of time and its existence can delve into philosophical and scientific debates. Some philosophical viewpoints, such as presentism, argue that only the present moment exists, while the past and future do not have independent existence. In such a framework, change could be understood as the succession of distinct present moments.
In the realm of physics, the theory of relativity and the concept of spacetime provide a framework for understanding the interplay between time and change. According to these theories, time and space are interconnected, and the nature of change is intricately tied to the geometry of spacetime.
Ultimately, the nature of time and its relationship with change is a complex topic, and different perspectives exist within philosophy, physics, and other disciplines.
