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 ...

Since the 1980s, string theory has emerged as the leading candidate for achieving every physicist’s dream: reconciling general relativity with quantum mechanics and thereby finding a tidy explanation ...

For decades, scientists have theorized about what lies beyond the third dimension and if there can exist a unified theory to explain all of the workings of the universe. This insurmountable task has ...

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 ...

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 ...

But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial splash, some ...

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 ...

String theory is an attempt to unite the two pillars of 20th century physics — quantum mechanics and Albert Einstein's theory of relativity — with an overarching framework that can explain all of ...
