Progress in the last decade has established that black holes are real, but what about their time-reversed cousins, white holes? Renowned physicist and author Carlo Rovelli joins Brian Greene to explore insights into these speculative astrophysical chimera.

This program is included in a 3-part series that explores 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.

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

Participants:
Carlo Rovelli

Moderator:
