Cosmic inflation is the idea that in the earliest moments of the universe, all cosmic matter expanded from nearly-nothingness into a sphere the size of a golf ball -- the matter moving at a speed faster than the speed of light.
Since this early expansion, the universe has been expanding outward a much slower speed.
On Monday, scientists on a project called BICEP2 announced that they'd discovered hard evidence of cosmic inflation.
Chao-Lin Kuo, an assistant professor on the team of scientists which located gravitational waves -- remnants of the Big Bang and cosmic inflation -- delivered the news to Linde, along with a celebratory bottle of champagne.
“Let’s just hope that it is not a trick,” Linde can be heard saying in the video.
