The Arrow of Time and How to Reverse It

The video explores the concept of time in physics, focusing on why time seems to have a direction, known as the arrow of time. It discusses the role of entropy in breaking time symmetry and how this affects our perception of time. The video also delves into the block universe model, explaining how entropy increases over time and its implications for the universe's expansion. The Big Bang is discussed as a point of low entropy, and the possibility of a symmetric universe is considered. The video concludes by suggesting further exploration into information theory and quantum entanglement to understand our perception of time.
