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 ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial splash, some ...

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 ...

Researchers at The University of South Carolina, USC, have proposed that a link between string field theory and quantum mechanics does exist. The link assumes that string field theory is a fully ...

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 ...

Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday experiences, they move at rapid speeds ...

The belief that all physical matter is made up of vibrating elements called "strings." Officially known as "superstring theory," it differs from traditional physics, in which all matter is made up of ...

It’s the theory everyone loves to hate. Depending on who you ask these days, string theory is either untestable, disconnected from reality or not even science. Right? Not so fast. While critics have ...
