Forget what you think you know about dark matter. After a 30-year search for a single, as yet unidentified, species of dark matter particle that would make up some 25% of the mass of the universe, physicists are starting to consider novel explanations. Some envision invisible matter hiding within the folds of extra spatial dimensions. Others suggest not one kind of dark matter particle, but numerous species inhabiting a shadow universe. Others still conjecture that dark matter doesn’t exist, and instead propose that the laws of gravity need modification. We’ll bring together leading thinkers on dark matter—the revolutionary and conventional alike—for a distinctly unconventional discussion on the dark universe.

Black holes may hold the key to understanding the most fundamental truths of the universe, but how do you see something that’s, well, black? Astronomers think they have the answer. Thanks to a global array of radio telescopes that turn the Earth into a giant receiver, we may soon have the first picture of the event horizon of Sagittarius A*, the black hole at the center of the Milky Way galaxy. And, with the power of math, scientists are going even further, using equations to “look” inside black holes, peering at the central singularity where general relativity and quantum mechanics collide. Join Brian Greene and other leading physicists and astronomers on a journey to make darkness visible.

Often viewed as “spooky” or downright bizarre, quantum mechanics is fueling a powerful new era of amazing technology. In this program, today’s top quantum physicists discuss the information shake-up underway—and predict when we can expect a quantum computer of our own.

Marcia Bartusiak joins Kip Thorne, Laura Danly and Rainer Weiss to demonstrate how two observatories on opposite sides of the country, called LIGO (Laser Interferometer Gravitational-wave Observatory), may open a new window on observing the cosmos—one based not in light but in gravity. Scientists have embarked on this joint experiment, seeking whispers of far-away violence—like the collision between distant black holes—rippling through the cosmos. It’s taken nearly a century, but technology has finally caught up to Einstein’s brilliance. His 1916 General Theory of Relativity predicted the existence of gravitational waves—undulations in the very fabric of space and time—and LIGO researchers are now poised to detect them.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

In recent years, machines have grown increasingly capable of listening, communicating, and learning—transforming the way they collaborate with us, and significantly impacting our economy, health, and daily routines. Who, or what, are these thinking machines? As we teach them to become more sophisticated, how will they complement our lives? What will separate their ways of thinking from ours? And what happens when these machines understand data, concepts, and behaviors too big or impenetrable for humans to grasp? We were joined by IBM’s WATSON, the computer Jeopardy! champion, along with leading roboticists and computer scientists, to explore the thinking machines of today and the possibilities to come in the not-too-distant future.
