A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

Researchers have used a 350-year-old theorem to better understand the strange nature of light. The team took a theorem used for describing pendulums and substituted the brightness of light in for what ...

Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Since the 17th century, when Isaac Newton and Christiaan Huygens ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...
