What is time? Isaac Newton described it as absolute, but Einstein proved that time is relative, and, shockingly, that time and space are intricately interwoven. Now recent work in string theory and quantum gravity suggests that space and time may not be fundamental. If this is true, what new picture of reality will emerge?

Are there limits to the human lifespan? Is it possible to stop the process of aging? On average, humans now live far longer than at any point in our history …

Brian Greene sits down with theoretical physicist Rafael Bousso to explore some of the deepest puzzles in modern physics. Their conversation centers on the black hole information paradox, one of …

Your eyes and ears don’t tell you the truth. That’s not what they’re for. The senses evolved to enable us to survive and succeed in the world, not to represent …

Andrew Strominger, renowned for his work on black holes, string theory, and quantum gravity, joins Brian Greene to describe his latest results and how some of them may be testable …

Creative thought is surely among our most precious and mysterious capabilities. But can powerful computers rival the human brain? As thinking, remembering and innovating become increasingly interwoven with technological advances, what are we capable of? What do we lose? Join Luciano Floridi, John Donoghue, Gary Small and Rosalind Picard for a thought-provoking program about thinking.
