Beyond Einstein: Gravitational Rainbows | World Science Festival

BEYOND EINSTEIN is a 3-part series exploring the wondrous implications of gravity pushed to the extreme, tackling dark energy, black holes and white holes. Renowned researchers join Brian Greene to discuss a range of insights–from confirmed to highly speculative–that extend Einstein’s vision of reality and advance our understanding of fundamental physical laws.

Gravitational Rainbows: Much as a gentle mist can split light waves into beautiful rainbows, dark energy may split gravitational waves into deeply revealing gravitational rainbows. Leading researcher Claudia de Rham joins Brian Greene to explore this compelling possibility.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

Participants:
Claudia de Rham

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.
