String theory posits a fundamental shift in our understanding of subatomic particles, suggesting that entities like electrons, protons, and quarks are not distinct objects but rather vibrations on incredibly tiny strings. This concept is framed through an analogy to music: just as different notes ar …

In this episode of the Lex Fridman Podcast, theoretical physicist Cumrun Vafa discusses string theory, a framework attempting to unify quantum mechanics and general relativity by describing fundamental particles not as points but as vibrating strings in ten or more dimensions. While string theory wa …

In this episode of the Lex Fridman Podcast, Harvard theoretical physicist Andrew Strominger explores the fundamental nature of black holes and their role in unifying physics. He begins by describing a black hole as a cosmic mirror where light that misses the event horizon swings around to reveal inf …
