After a decades-long search for answers about the creation of the universe, scientists believe they have found a smoking gun.

On Monday, a team of scientists announced the first direct evidence for what's known as cosmic inflation, or proof of the first fractions of a second that were initiated after the Big Bang.

The cosmic inflation theory proposes that less than a trillionth of a second after the Big Bang, the universe expanded faster than the speed of light, and tiny ripples in the violently expanding energy field eventually grew into the large-scale structures of the universe.

Now radio astronomers are confirming this hypothesis—evidence was found in detecting the gravitational waves or ripples in space-time that were put forth nearly 14 billion years ago when the universe burst into existence.

Clem Pryke is an experimental cosmologist at the University of Minnesota and one of the principal investigators on the team that made the discovery. He joins The Takeaway to explain this scientific breakthrough.
