Existence of the Past

Summary of my bookmarked videos from Mar 6th, 2023


  • Does the Past Still Exist?

    In the video titled "Does the Past Still Exist?" by Sabine Hossenfelder, the concept of time and its relationship to space is explored. The video discusses Albert Einstein's theory of space-time, where time becomes a dimension similar to space. This leads to the idea of the block universe, where all moments of time exist simultaneously. Our perception of past, present, and future is just an illusion. The video explains the concepts of space-time diagrams, special relativity, and the relativity of simultaneity. Overall, it challenges our common understanding of time and presents a different perspective on its nature.
