Black holes are gravitational behemoths that dramatically twist space and time. Recently, they’ve also pointed researchers to a remarkable proposal—that everything we see may be akin to a hologram.

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.

This program, Ending the Epidemic: Science Advances on AIDS, brings together leading researchers on the forefront of scientific efforts to understand and attack the virus that causes AIDS. Moderator Richard …

Brian Greene and physicist Samir Mathur explore one of the deepest puzzles in modern physics, the true nature of black holes and the fate of information in the universe. Their …

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?

It’s an old question: What is consciousness? Today, sophisticated brain imaging technologies, clinical studies, as well as the newfound ability to listen to the whisper of even an individual nerve cell, are bringing scientists closer than ever to the neurobiological basis of consciousness.
