String theory began over 50 years ago as a way to understand the strong nuclear force. Since then, it’s grown to become a theory of everything, capable of explaining the nature of every particle ...

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics ...

The strings of string theory are unimaginably small. Your average string, if it exists, is about 10-33 centimeters long. That's a millionth of a billionth of a billionth of a billionth of a ...

String theory fixes this because the graviton is a loop, not a point particle. Its interactions are smeared around that string, handily avoiding the explosion of mathematical infinities you get ...

String theory is the idea that everything in the universe, every particle of light and matter, is comprised of miniscule vibrating strings. These strings are truly tiny, ...

String theory seems to me to have failed to deliver what it had promised in the ’80s, and is one of the many ‘nice-idea-but-nature-is-not-like-that’ that dot the history of science.
