Today's physicists are struggling with a quandary. They have accepted two separate theories that explain how the universe works: Albert Einstein's general theory of relativity, which describes the ...

String theory is a hypothetical idea that purports to be a theory of everything, able to explain the fundamental microscopic aspects of all of reality, from the forces of nature to the building blocks ...

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 ...

Mathematicians are exploring a string duality between F-theory and heterotic string theory in eight dimensions. Simply put, string theory is a proposed method of explaining everything. Actually, there ...

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 ...

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, ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. String theory is perhaps the most controversial big idea in all of ...

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 ...
