time's arrow

Time's arrow refers to the concept that time seems to flow in one direction: from the past to the future. This idea is closely tied to the Second Law of Thermodynamics, which states that in a closed system, disorder, or entropy, tends to increase over time. For example, when you break a glass, it shatters into many pieces, showing a move from order to disorder. This one-way trajectory of time influences our daily experiences, such as aging, and shapes how we understand events and causality in the universe.
