In today’s episode of Theories of Everything, Curt Jaimungal is joined by renowned physicists Peter Woit and Joseph Conlon to delve into the complexities of String Theory. Together, they explore its potential as a unified framework for understanding the fundamental forces of the universe, discussing both its strengths and the criticisms it faces. Peter Woit is a renowned mathematical physicist and outspoken critic of string theory, and Joseph Conlon is a distinguished theoretical physicist and strong proponent of string theory.

NOTE: The video of Brian Greene in the introduction was intended to serve as a visual representation related to string theory as a general subject. It wasn’t meant to imply his support or opposition to string theory without understanding the details of it. I love Brian Greene. I even spoke to him here for the podcast. https://youtu.be/O2EtTE9Czzo. - Curt
