Is time a circle or a line?

The nature of time is a philosophical and scientific question that has puzzled thinkers throughout history. Two contrasting views of time are often considered: the linear and the cyclical. Linear Time: The linear view of time posits that time flows in a continuous and irreversible direction, moving from the past to the present and on to the future. This perspective is common in Western thought and is associated with the arrow of time, where events occur in a sequence, and causality operates in a forward direction. Cyclical Time: The cyclical view of time suggests that time is repetitive and follows a circular or periodic pattern. This perspective is found in various cultures and belief systems, where events and ages repeat in cycles or seasons. In cosmology, some theories propose a cyclic universe model, where the universe undergoes an infinite series of expansions and contractions. The nature of time remains a subject of exploration in physics, with theories like the block universe suggesting that past, present, and future exist simultaneously. The philosophical implications of these perspectives continue to be debated.
