WASHINGTON — Reality comes in layers. Everything we see in the world around us, scientists tell us, is made of atoms and combinations of atoms called molecules. Atoms are themselves made of tiny ...

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 ...

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 ...

The final installment of a three-part NOVA series about "String Theory," a new branch of science that seeks to explain nothing less than how the universe works, airs on PBS. Ray Suarez speaks with ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of Ask a Spaceman and Space Radio, and author of "Your Place in the Universe." Sutter contributed this article ...

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...

On a more serious note, the title of the article says "Requiem". I was expecting it to pronounce String Theory dead, but the conclusion seems a little bit ambiguous. Are people still working at it ...

STRING theory: you love it or loathe it. To some it represents our best hope for a route to a “theory of everything”; others portray it as anything from a mathematically obtuse minefield to a ...
