Скачать или смотреть Past doesn't exist, here's why.

In this video, we explore a provocative idea from physics and philosophy: the past may not be a permanent, stored reality, but something that survives only through physical records. From entropy and the arrow of time to quantum mechanics and information theory, this essay examines how history is reconstructed from traces — fossils, light from distant galaxies, memories, written documents, and microscopic correlations embedded in the present moment.

We dive into thermodynamics and the growth of disorder, asking why time appears to move in one direction. We examine how records are formed, how they decay, and what it really means for an event to “have happened.” If all physical traces of an event disappear, in what sense does that event still exist? Is the universe a fixed block where past, present, and future coexist, or is only the present physically real?

This video blends physics, philosophy, and everyday examples to challenge our intuition about time. It is not about denying history, but about understanding the fragile physical processes that preserve it. The past, as you’ll see, may be less like a permanent archive and more like a pattern written into the present — one that can fade, erode, or be erased.
