The Mind-Bending Physics of String Theory

What Led to String Theory? (1x1)

: 01, 2023

After a quick review of 20th-century physics, Professor Kachru introduces the concept of unimaginably minute strings. These appear to solve longstanding problems in quantum mechanics and achieve Einstein’s dream of a quantum theory of gravity. Learn why string theory predicts extra dimensions of space—10 in total, according to some models. Then explore the startling implications.
