David Gross shared the 2004 Nobel Prize in Physics and is the director of the Kavli Institute for Theoretical Physics at the University of California at Santa Barbara. Gross is one of the leading ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

For decades, scientists have theorized about what lies beyond the third dimension and if there can exist a unified theory to explain all of the workings of the universe. This insurmountable task has ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The greatest scientific legacy that Albert Einstein left us is this: ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?" Forty-five years later, ...

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10 500 versions of spacetime, each with their own laws of physics. But ...

On a more serious note, the title of the article says "Requiem". I was expecting it to pronounce String Theory dead, but the conclusion seems a little bit ambiguous. Are people still working at it ...

String theorists are shifting focus to solve some rather sticky problems in physics. Over the past few years, string theory has been less about trying to find a unifying description of all forces and ...

String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a ...

Scientists have found what they say is a link between complex number theory and string theory. A mathematician and physicist working together found the connection, which they say is part of plotting ...
