Why Human Civilization Has a Physical Limit | Leonard Susskind

Humanity has been growing for 10,000 years, but physics says we are about to hit a wall. In this video, we explore why the dream of "infinite expansion" across the stars is actually impossible. From the thermodynamics of waste heat that could cook the Earth in just 400 years, to the speed of light and the Bekenstein Bound of information, we break down the hard limits of our universe. Is a Type III Kardashev civilization actually a fantasy? We look at why entropy, dark energy, and the laws of spacetime mean that every civilization—no matter how advanced—has an absolute ceiling. In this video, we cover: The Waste Heat Limit: Why "Clean Energy" won't save us from overheating. The Cosmic Speed Limit: Why we are trapped in our Local Group. The Bekenstein Bound: The maximum amount of information the universe can "think." The Heat Death of the Universe: The ultimate end of all energy. Is this the end of hope, or the beginning of maturity? Let’s dive into the physics of our final boundary.
