Why Symmetry Governs the Universe | Leonard Susskind

Описание: Have you ever wondered why the universe is so orderly? Why the laws of physics don't just change from one day to the next? The answer isn't "stuff"—it’s Symmetry. In this deep-dive lecture, we explore the hidden architecture of existence, revealing how the most fundamental laws of nature are actually forced upon us by a cosmic need for balance.
From the groundbreaking work of Emmy Noether to the "broken mirrors" that created matter and life, we look under the hood of reality to see why particles, forces, and even time itself are just expressions of mathematical symmetry. This isn't just about pretty patterns; it's about the rigid logic that prevents the universe from falling apart.
Key Topics Explored:
• The Definition of Symmetry: Why "change that doesn't make a change" is the foundation of physics.
• Noether’s Theorem: How the symmetry of time literally creates the Law of Conservation of Energy.
• The Beauty of Imperfection: Why "Symmetry Breaking" was necessary for the Big Bang to create the stars and us.
• Particles as Rotations: Why an electron isn't a "thing," but a mathematical vibration.
• Forces as Messengers: How light and gravity exist only to keep the universe’s books balanced.
