Symmetry underlines our whole understanding of the universe. And the deeper we look, the more symmetries we find, reflecting our world in new and beautiful ways. Subscribe for weekly science videos: http://bit.ly/RiSubscRibe Symmetry is vital to understanding and predicting how our universe works. The relationship between symmetry and the mechanics of the universe is fundamental to physics. From Noether’s theorem to the new and exciting world of local symmetries being revealed by modern day physics, Tara Shears explores the physics of symmetry. By revealing nature’s parameters, symmetry gives definition to the world as we understand it. It is a fundamental principle that makes phenomena repeatable and predictable. But if symmetries are so pervasive and influential in our world, why do we see so much asymmetry and chaos?
