In a supercooled lab setting, a tiny crystal has quietly flipped a half-century-old assumption on its head. Scientists at Rice University have reported the first direct observation of a long-predicted ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...

These subtle fluctuations, first envisaged by physicist John Wheeler, are thought to arise naturally in several leading theories of quantum gravity. But because different models of gravity predict ...
