Nova: The Fabric of the Cosmos

The Fabric of the Cosmos


Watch a live webcast with Brian Greene November 2 at 10pm - Watch the webcast. Hosted by The World Science Festival, Columbia University, and NOVA, this webcast will allow in-theatre and digital audiences to further explore the program's rich material in direct conversation with Greene and other featured program participants. You can ask questions in advance at the World Science Festival Facebook page.


"The Fabric of the Cosmos," a four-hour series based on the book by renowned physicist and author Brian Greene, takes us to the frontiers of physics to see how scientists are piecing together the most complete picture yet of space, time, and the universe. With each step, audiences will discover that just beneath the surface of our everyday experience lies a world we’d hardly recognize—a startling world far stranger and more wondrous than anyone expected.


Brian Greene is going to let you in on a secret: We've all been deceived. Our perceptions of time and space have led us astray. Much of what we thought we knew about our universe—that the past has already happened and the future is yet to be, that space is just an empty void, that our universe is the only universe that exists—just might be wrong.


Interweaving provocative theories, experiments, and stories with crystal-clear explanations and imaginative metaphors like those that defined the groundbreaking and highly acclaimed series "The Elegant Universe," "The Fabric of the Cosmos" aims to be the most compelling, visual, and comprehensive picture of modern phys

One harmonious possibility is that string enthusiasts and loop quantum gravity aficionados are actually constructing the same theory, but from vastly different starting points. That each theory involves loops-in string theory, these are string loops; in loop quantum gravity, they're harder to describe non mathematically, but. roughly speaking, they're elementary loops of space-suggests there might be a connection. This possibility is further supported by the fact that on a few problems accessible to both, such as blackhole entropy, the two theories agree fully. And on the question of spacetime's constituents, both theories suggest that there is some kind of atomized structure. Page 490, Fabric of the Cosmos by Brian Greene
