Some researchers propose that advancing AI to the next level will require an internal architecture that more closely mirrors the human mind. Rufin VanRullen joins Brian Greene to discuss early results from one such approach, based on the Global Workspace Theory of consciousness.

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.

Can conscious self-awareness be coded in an algorithm? According to distinguished computer scientist Lenore Blum and Turing Award Laureate Manuel Blum the answer is "yes," and they join Brian Greene to explain their approach.
