For decades, scientists have taken issue with “string theory”—a theory of the universe which contends that the fundamental forces and matter of nature can be reduced to tiny one-dimensional filaments ...

The apparent inability of physics' string theory to be proved right or wrong is one of the stickiest – and argument-generating – problems in modern science. But now researchers at the University of ...

Detractors of string theory have been deriding it for years, claiming that there is no way to test it. However, with a paper published in Physical Review Letters titled “Falsifying Models of New ...

String trimmers can be a pain. Many an hour on a weekend day has been lost while trying to feed string into a fickle trimmer or fruitlessly yanking a gas-powered trimmer's pull cord while the engine ...
