Scientists have confirmed with 99.996 percent certainty that dark energy exists, and is causing the universe to expand.
“Our universe is a mysterious place,” says Jennifer Ouellette at Discovery News. Roughly 4 percent of it is made of ordinary matter like stars and planets. The rest, according to physicists, is a combination of mysterious dark matter — which functions as an invisible glue that holds the universe together — and an even lesser-understood substance call dark energy, which is “causing the cosmos to expand at an accelerating rate.”
