Tiden is a concept that refers to the flow of time and its measurement. It is often associated with the natural cycles of day and night, seasons, and the aging process. People use various tools, such as clocks and calendars, to track and organize time, which plays a crucial role in daily life and planning. In many cultures, Tiden is also linked to philosophical and scientific discussions about the nature of existence and reality. The study of time involves various fields, including physics, where concepts like time dilation and the space-time continuum are explored, revealing the complexities of how time interacts with the universe.
