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 ...

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?” Hawking, who later became my ...

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 ...

(via Sabine Hossenfelder) Over the past decade, string theorists have struggled to reconcile their elegant mathematical theory with the reality of our observable reality, inventing what has been ...

A detailed look at the Universe reveals that it's made of matter and not antimatter, that dark matter and dark energy are required, and that we don't know the origin of any of these mysteries. However ...

One of the strangest ideas about the nature of the universe could be one of the most important. Do long, thin, and incredibly dense strands of matter called cosmic strings wind their way throughout ...

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 ...

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 ...

One of the most frustrating aspects of string theory has been its inability to make predictions that are experimentally verifiable. This hasn't been due to lack of effort on the part of the scientists ...

Physicists who have been roaming the “landscape” of string theory—the space of zillions and zillions of mathematical solutions of the theory, where each solution provides the kinds of equations ...

Three decades ago, a British documentary series named Connections aired, which showed viewers how various scientific achievements and discoveries were really interrelated, no matter how disparate they ...
