Experiment Proves Einstein Right About Universe

A new experiment has proven another of Einstein's theories to be right on the money. Einstein's general theory of relativity predicts the speed at which galaxies move toward each other and the rate at which the universe is expanding. A team of cosmologists recently measured a slice of the universe's history, between 5 and 6 billion years ago, and discovered that Einstein was spot on, reports the Telegraph.

''The results are the best measurement of an intergalactic distance ever made, which means cosmologists are closer than ever to understanding why the universe's expansion is accelerating," says one team member. "Einstein's theory has passed its most stringent test yet at extra-galactic scales." The results might provide new insight into dark energy, the little understood force driving the acceleration, notes the Telegraph. (More Albert Einstein stories.)
