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 ...

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 ...

Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the Large Hadron Collider.

(via Sabine Hossenfelder) Over the past decade, string theorists have struggled to reconcile their elegant mathematical theory with the reality of our observable reality, inventing what has been ...

String theory's equations give rise to a near infinite variety of potential universes in a 'landscape.' This landscape is surrounded by a 'swampland' of solutions that are incompatible with any ...

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 ...

(via Sabine Hossenfelder) The BBC claims that researchers have found the first evidence for string theory, citing a recent discovery of long-wavelength gravitational waves that might indicate the ...

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 ...

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 ...
