Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...

There are gazillions of different possible universes that can be described and understood using the tools provided by string ...

Bootstrapping strings Evidence that string theory could be the sole viable “theory of everything” has emerged in a new theoretical study of particle scattering. (Courtesy: iStock/Anadmist) Striking ...

Stanford math professor Keith Devlin talks about two new books that call into question the entire idea of string theory. The theory states that tiny vibrating strings make up everything, but some ...

Physicists looking for a way to test their theory about strings might make more progress if they tangle them up. String theory — equations that aspire to explain all of nature’s particles and forces — ...

WEST LAFAYETTE, Ind. – The recent detection of gravitational waves - about 100 years after Albert Einstein theorized them - shook the science world. It has the planet talking, from casual science fans ...

For decades researchers have tried to wrest testable predictions from string theory, the leading candidate for a more fundamental understanding of the universe. Now physicists say they have used one ...

You may not have heard of knot theory. But take it from Bill Menasco, a knot theorist of 35 years: This field of mathematics, rich in aesthetic beauty and intellectual challenges, has come a long way ...
