The passage of time can be understood in different ways depending on the context and the theoretical framework being used. In the context of general relativity, which describes gravity and the behavior of spacetime, the expansion of the universe does play a role in the passage of time.
According to the theory of general relativity, the fabric of spacetime can be influenced by the distribution of matter and energy. In an expanding universe, the distances between galaxies, clusters of galaxies, and other cosmic structures are increasing over time. This expansion affects the fabric of spacetime itself, causing it to stretch or expand.
In this framework, the passage of time is intimately connected to the expansion of spacetime. As the universe expands, the distances between objects increase, and this expansion can be seen as the passage of time on a cosmological scale. From this perspective, time is not a separate entity but is intertwined with the geometric properties of spacetime.
It's worth noting that this understanding of time is specific to the framework of general relativity and its description of an expanding universe. In other contexts, such as quantum mechanics or philosophical discussions on the nature of time, different interpretations and perspectives may be considered.
