Supermassive Black Holes Rethinking Their Origin

The mechanism of collapsing stars falls short of explaining the existence of supermassive black holes—giants that weigh millions or even billions of times the mass of the Sun. Astrophysicist Priya Natarajan proposes an alternative: these colossal black holes may form directly from the collapse of swirling galactic dust and gas. She joins Brian Greene to explore this process and discuss the latest observational evidence supporting it. • This program is part of the Big Ideas series, supported by the John Templeton Foundation. • Participant: Priya Natarajan • Moderator: Brian Greene • 00:00 - Introduction • 02:39 - History of the concept of black holes • 06:30 - Formula of the event horizon • 07:43 - Visualization of a black hole • 08:40 - Chandrasekhar's contribution of black hole knowledge • 10:06 - Einstein and the limits of our understanding of black holes • 11:50 - Oppenheimer and Snyder's work theorizing how a black hole would form • 13:32 - Penrose's work on gravitational collapse and the space-time singularity • 14:53 - Wheeler coining of the term black hole • 16:00 - Ghez's mapping of the shape of space and the motion of stars around black holes • 18:00 - Alternate ways black holes could form • 22:09 - Overmassive black hole galaxy (OBG) • 23:40 - Sequence of formation of black holes • 26:54 - James Webb Space Telescope's detection of OBG • 31:50 - Primordial black holes • 33:38 - Evolution of black holes • 34:26 - Credits • SUBSCRIBE to our YouTube Channel and ring the bell for all the latest videos from WSF • VISIT our Website: http://www.worldsciencefestival.com • LIKE us on Facebook: / worldsciencefestival • FOLLOW us on Twitter: / worldscifest • #worldsciencefestival #briangreene #blackholes #astrophysics
