Scientists at right, from bottom, John Kovac, Chao-Lin Kuo, Jamie Bock and Clem Pryke hold a news conference at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., Monday, March 17, 2014, regarding their new findings on the early expansion of the universe. Scientists say that the universe was born almost 14 billion years ago, exploding into existence in an event called the Big Bang. Now these researchers say they’ve spotted evidence that a split-second later, the expansion of the cosmos got a powerful-jump start. Experts called the discovery a major advance if confirmed.
