Universe Expanding Faster Than After Big Bang

The expansion of the universe has been speeding up for the past 5 billion years, but that hasn’t always been the case.

Shortly after the Big Bang—the event scientists believe occurred 13.8 billion years ago that created the universe and everything in it—the universe was expanding at a much slower rate.

"If we think of the universe as a roller coaster, then today we are rushing downhill, gaining speed as we go," Nicolas Busca of the Laboratoire Astroparticule et Cosmologie of the French Centre National de la Recherche Scientifique (CNRS), one of the lead authors of the study, said in a statement. "Our new measurement tells us about the time when the universe was climbing the hill—still being slowed by gravity."
