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 ...

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 ...

String theory has long been touted as physicists' best candidate for describing the fundamental nature of the universe, with elementary particles and forces described as vibrations of tiny threads of ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...

Physics has the potential to reveal the fundamental nature of the universe. Recent theories show that neither ``common sense" nor our senses are reliable interpreters of reality. Physics has the ...

In 1998, astronomers discovered dark energy. The finding, which transformed our conception of the cosmos, came with a little-known consequence: It threw a wrench into the already daunting task of ...

Fifty-eight years after it first appeared, string theory remains the most popular candidate for the “theory of everything,” the unified mathematical framework for all matter and forces in the universe ...
