Time out of mind - Finding Your Science

The video explores the concept of time in everyday life and its relation to physics. It highlights the asymmetry in our perception of time, where we remember the past and influence the future, contrasting with the time-reversal symmetry in physical laws. The discussion extends to cosmology, suggesting that the universe's expansion might define a time direction, linked to increasing entropy. The speaker speculates that future breakthroughs in physics could radically change our understanding of time, akin to past revolutions like relativity or quantum mechanics.
