Until recently, string theory — long heralded as a 'theory of everything' — hadn't been particularly good at explaining anything. But at a workshop this month at the Kavli Institute for Theoretical ...

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 ...

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

Quantum field theory (QFT) remains the cornerstone of our understanding of particle interactions, unifying the principles of quantum mechanics with special relativity by describing particles as ...

Imagine you are sitting in a big symphony hall, and you're listening to an orchestra play for the first time. The orchestra is performing a Violin Concerto by Beethoven. As the soloist runs her hands ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single mathematical framework capable of describing the entirety of the known universe. The ...

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

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

For decades, physicists have been trying to combine quantum physics and general relativity into a single, unified theory. One of the leading contenders is string theory, an elegant vision in which ...

Einstein desperately wanted a unified theory of physics. Thanks to gravitational waves—the poster child of general relativity—his wish might just come true. Gravitational waves are ripples in the ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of Ask a Spaceman and Space Radio, and author of "Your Place in the Universe." Sutter contributed this article ...
