summary

In this blog post, the author explores the philosophical question of whether the past still exists. They discuss different interpretations of time, including the block universe theory and the idea that time is merely a human construct. The author explores various arguments and thought experiments to probe the concept of the past and its relationship to the present and future. They also examine scientific theories, such as the branching of multiple universes and the possibility of time travel. Ultimately, the author concludes that while the past might exist in some sense, our access to it is limited to our memories and historical records, making it a subjective and complex concept.
