The universe was born almost 14 billion years ago, exploding into existence in an event called the Big Bang. Now researchers say they’ve spotted evidence that a split-second later, the expansion of the cosmos began with a powerful jump-start.

Experts called the discovery a major advance if confirmed by others. Although many scientists already believed that initial, extremely rapid growth spurt happened, finding this evidence has been a key goal in the study of the universe. Researchers reported Monday that they did it by peering into the faint light that remains from the Big Bang…Cont
