String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

String theory remains elusive as a 'provable' phenomenon. But a team of physicists has now taken a significant step forward in validating string theory by using an innovative mathematical method that ...

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 ...

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics describes all known fundamental particles and three forces: electromagnetism, ...

In the late 19th century, classical physics seemed complete. Scientists believed they had uncovered all the laws governing the universe, which appeared to operate like a precise machine. But ...

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 ...

The idea of string theory was first floated in the 1960s and '70s. Scientists may have found the first observational evidence that supports string theory -- a hypothetical framework in physics ...

String theory has long been presented as physicists' best candidate for describing the fundamental nature of the Universe. Yet, at the beginning of the 21st century, it became apparent that most ...

Michio Kaku, a Harvard graduate and theoretical physicist, is renowned for his work in string theory and science communication. Born in California to Japanese-American parents, Kaku built an early ...
