Hosted by physicist Brian Greene, ‘The Fabric of the Cosmos’ is a journey to the frontiers of known physics in an effort to explore the deepest and most puzzling cosmological queries.
Hard as it is to swallow, cutting-edge theories are suggesting that our universe may not be the only universe. Instead, it may be just one of an infinite number of universes that make up the “multiverse.” In this show, Brian Greene takes us on a tour of this brave new theory at the frontier of physics, showing what some of these alternate realities might be like. Some universes may be almost indistinguishable from our own; others may contain variations of all of us, where we exist but with different families, careers, and life stories. In still others, reality may be so radically different from ours as to be unrecognizable. Brian Greene reveals why this radical new picture of the cosmos is getting serious attention from scientists. It won’t be easy to prove, but if it’s right, our understanding of space, time, and our place in the universe will never be the same.

Is There Anything Beyond Quantum Computing?
A quantum computer is a device that could exploit the weirdness of the quantum world to solve certain specific problems much faster than we know how to solve them using a conventional computer. Alas, although scientists have been working toward the goal for 20 years, we don’t yet have useful quantum computers. While the theory is now well-developed, and there’s also been spectacular progress on the experimental side, we don’t have any computers that uncontroversially use quantum mechanics to solve a problem faster than we know how to solve the same problem using a conventional computer.
No more. The shrieks and the howls are all we’ve got now. They pass for intellectual debate, addressed in academic departments and dissected in journals that once had greater concerns in mind. The isms that once struggled for primacy had given way to topical outrages: about income inequality, about the gold standard, about drones, about Benghazi, about Israel, about Stephen Colbert. And that’s the real danger: not that this political camp or that is growing intolerant, but that both are getting incorrigibly dumb.
