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 ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to [email protected]. Are multiverses real? If so, what do they look ...

Columnist Natalie Wolchover examines the latest developments in the “forever war” over whether string theory can describe the ...

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 ...

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 ...

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 ...

It’s not easy being a “theory of everything.” A TOE has the very tough job of fitting gravity into the quantum laws of nature in such a way that, on large scales, gravity looks like curves in the ...

Michael Dine, a professor of physics at UC Santa Cruz, will take part in the World Science Festival now under way in New York City, joining a panel discussion on string theory on Thursday, May 30, on ...

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 ...

(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 ...

SciAm’s George Musser takes a crack at explaining one of the most complex (and controversial) concepts in all of physics — all in less than 26 seconds. Not bad, Musser. But can you do it for M-theory?
