Neutrinos, Matter, and Antimatter: The Yin Yang of the Big Bang | World Science Festival

What happened to all of the universe’s antimatter? Can a particle be its own anti-particle? And how do you build an experiment to find out? In this program, particle physicists reveal their hunt for a neutrino event so rare, it happens to a single atom at most once every 10,000,000,000,000,000,000,000,000 years: far longer than the current age of the universe. If they find it, it could explain no less than the existence of our matter-filled universe.

This program is part of the BIG IDEAS SERIES, made possible with support from the JOHN TEMPLETON FOUNDATION.

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.
