Carl Sagan Explains Why Your Tomorrow Already Exists Right Now

In this powerful clip, Carl Sagan explores the profound mystery of sleep and consciousness. He explains how the brain that wakes up tomorrow is not the same one that fell asleep tonight — suggesting that in a very real sense, we die every night and are reborn every morning. This thought-provoking idea challenges our understanding of the self, time, and existence. Sagan masterfully connects science and philosophy, making us rethink what it really means to wake up to a new day. If you love deep cosmic wisdom and mind-expanding ideas, this video is a must-watch.
