In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

In a nutshell, string theory is a sprawling realm of theoretical physics that assumes that tiny vibrating strings are the ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...

For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and ...

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, ...

Here’s what you’ll learn when you read this story: String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to ...
