Why is there something rather than nothing? And what does ‘nothing’ really mean? More than a philosophical musing, understanding nothing may be the key to unlocking deep mysteries of the universe, from dark energy to why particles have mass. Journalist John Hockenberry hosts Nobel laureate Frank Wilczek, esteemed cosmologist John Barrow, and leading physicists Paul Davies and George Ellis as they explore physics, philosophy and the nothing they share.

Extra dimensions of space—the idea that we are immersed in hyperspace—may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still--but ultimately hit a dead end. Modern research has advanced the subject in ways he couldn’t have imagined. John Hockenberry joins Brian Greene, Lawrence Krauss, and other leading thinkers on a visual tour through wondrous spatial realms that may lie beyond the ones we experience.

Consciousness is a terrible curse. Or so says a character in screenwriter/director Charlie Kaufman’s Being John Malkovich. Part theater of the absurd and part neuroscience fiction, the Oscar-winning filmmaker’s work captures the splintering between what we perceive and what we feel as our brains grapple with multiple layers of reality. Neuroscientist Giulio Tononi, one of the world’s leading sleep researchers, casts new light on the science of the mind, probing where and how consciousness is generated in the brain. Watch this spellbinding conversation between Kaufman, Tononi, and moderator Alan Alda as they explore and explain the art, science, and mystery of consciousness.

If you believe the world’s leading physicists, the vast majority of matter in the universe is hiding in plain sight. For nearly a century, evidence has mounted that the gravitational pull necessary to keep clusters of galaxies intact, as well as stars within galaxies from flying apart, requires far more matter than we can see—matter, according to the experts, that has eluded our telescopes, because it does not give off light. Problem is, such “dark matter” has also eluded one specially designed detector after another that researchers have deployed to catch it. Which raises the big question: What if we have failed to find dark matter because it isn’t there? Join leading physicists on a scientific treasure hunt that has proved more challenging than anyone expected, and may ultimately require rethinking some of our most fundamental ideas about the universe.
