What Is Nothingness, Really? | Leonard Susskind

You think you know what "nothing" is. Empty space. A pure vacuum. The absence of everything. But modern physics and philosophy reveal a profound truth: Absolute nothingness is impossible. In this video, we dismantle the oldest illusion in human history. From the curving geometry of spacetime in General Relativity to the seething, jittering quantum foam of Quantum Field Theory, we explore why "nothing" is a scientific and logical impossibility. We dive into the Casimir effect, string theory, and Heisenberg's Uncertainty Principle to show that reality always bottoms out at something. Finally, we answer the ultimate philosophical question—"Why is there something rather than nothing?"—and discover why existence isn't a miracle, but a mathematical and logical necessity. 👇 Chapters / Timestamps (Great for SEO & Viewer Retention): 0:00 - The Illusion of the "Void" 1:25 - Why Empty Space is Still "Something" 3:10 - The Linguistic Trap of Absolute Nothingness 4:45 - Quantum Mechanics & The Seething Vacuum 7:05 - Virtual Particles & The Casimir Effect 8:50 - What about String Theory & Loop Quantum Gravity? 10:30 - Why Is There Something Rather Than Nothing? 13:15 - The Liberating Truth About Reality #Physics #Philosophy #QuantumMechanics #Science #Astrophysics #Existential
