String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...

The “Red String Theory” captivating social media is a belief that an invisible thread connects soul mates destined to meet and fall in love. Originating from Chinese mythology, the theory is fueled by ...

Scientists propose a bold test of string theory by identifying a hypothetical five-particle family, called a 5-plet, that string theory cannot produce. If such a particle were found at the LHC, it ...

During the 20th century, physicists introduced and refined string theory, a theoretical framework that promised to unite quantum mechanics and general relativity. Instead of point-like particles, ...

"But one of the drawbacks of string theory is that it operates in high-dimensional math and a vast 'landscape' of possible universes, making it fiendishly difficult to test experimentally," Heckman ...

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 ...

For decades, string theory has stood as a leading, albeit controversial, candidate for a theory of everything, weaving together the universe’s fundamental forces and particles into a single, grand ...

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 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 ...
