Oct. 17, Tuesday -- Our entire outlook is about to change as physicists put forward theories that our universe is just a tiny pocket in a stupendous landscape, says Leonard Susskind, professor of ...

Evidence that the universe is made of strings has been elusive for 30 years, but the theory’s mathematical insights continue to have an alluring pull Brian Greene Contributing Writer In October 1984 I ...

As modern physics has developed a better understanding of how the universe operates at its most fundamental levels, one thing has become increasingly clear: we're damned lucky to be here at all. The ...

The holographic principle is a property of quantum gravity theories which resolves the black hole information paradox within string theory. First proposed by Gerard 't Hooft, it was given a precise ...

During a day of talks at Stanford University, theoretical physicist Leonard Susskind explained “Why I Teach Physics to Old Codgers, and How It Got to Be a YouTube Sensation.” Stanford professor ...

String theory strutted onto the scene some 30 years ago as perfection itself, a promise of elegant simplicity that would solve knotty problems in fundamental physics—including the notoriously ...

Einstein introduced the cosmological constant to his equations of general relativity because he believed the universe was static. Faced with evidence that the universe was actually expanding, however, ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...
