Cumrun Vafa: Is String Theory Actually Science? (#368)

Into the Impossible With Brian Keating

NOTE

Exploring the Motivation and Structure of Our Universe

Studying theoretical questions helps understand the fundamental structure of our universe, such as the particles and forces that exist. By questioning why certain particles and forces exist and not others, we delve into the motivation behind the universe's composition. The consideration of forces like gravity can limit the possibilities of the forces and particles present in the universe. Super symmetry theories offer a simplified approach to understanding forces like gluons, but gravity plays a crucial role in determining the parameters and constraints within these theories. The concept that gravity can influence the composition of forces in our universe motivates physicists to explore further without the need for super symmetry. Using string theory as a model, physicists aim to comprehend how the universe could potentially resemble our own, following the tradition of using toy models like the harmonic oscillator in physics for understanding complex phenomena.
