Step into the mind of Nobel laureate Alain Aspect, one of the pioneers who turned quantum weirdness into experimental reality. In this conversation with Brian Greene, Aspect retraces the century-long quest to understand quantum entanglement, nonlocality, and Bell’s theorem—ideas that shattered classical physics and redefined reality itself.

Winner of the 2022 Nobel Prize in Physics, Aspect’s groundbreaking experiments proved that Einstein was wrong. Here, he reveals how that discovery shattered classical intuition and redefined what “reality” means.

This program is part of the Rethinking Reality series, supported by the John Templeton Foundation. 

Participant: Alain Aspect
Moderator: Brian Greene

ABOUT WORLD SCIENCE FESTIVAL: 
The World Science Festival (WSF) is a multimedia organization bringing the most transformative ideas in science to global audiences. Through long- and short-form videos spanning physics, cosmology, quantum mechanics, biology, neuroscience, consciousness, medicine, space exploration, the dilemma of free will, artificial intelligence, engineering, robotics, and beyond. WSF gathers world-renowned scientists, artists, and thinkers for dynamic discussions, debates, lectures, performances, films, and immersive live experiences. 

Founded in 2008 and headquartered in New York City, the World Science Festival is a production of the World Science Foundation, a 501(c)(3) nonprofit organization. Our mission is to cultivate a public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future. With live events reaching millions worldwide and hundreds of millions of digital views, WSF continues to expand its global impact through festivals, educational initiatives like World Science U, and digital content that explores the near and far future of our world.
