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, ...

String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...

New research from a CU Boulder physicist might break open the mathematical puzzle that has stalled string theory research for decades A University of Colorado Boulder physicist is one step closer to ...

For the last 30 years of his life, Albert Einstein tried to come up with a Unified Field Theory, to combine the equations of Gravity and Electromagnetism. Unfortunately, he failed. In 1984, two Jewish ...

String theory used to get everyone all tied up in knots. Even its practitioners fretted about how complicated it was, while other physicists mocked its lack of experimental predictions. The rest of ...

A team of theoretical physicists and astronomers has calculated that any hidden extra dimension beyond our familiar three-dimensional space, a world known in physics parlance as a 3-brane, must be ...
