Beyond Einstein: Gravitational Echoes

Gravitational Echoes: Just as sound waves can echo off a distant rockface, light waves can echo off of black holes. Renowned researchers Erin Kara and Shep Doeleman join Brian Greene to explore the exotic physics that rules all that happens near the edge of a black hole.

BEYOND EINSTEIN is 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:
Shep Doeleman
Erin Kara

Moderator:
Brian Greene
