A team of astronomers released what's being called a monumental discovery this week about the origins of the universe. Using telescopes at the South Pole, scientists discovered gravitational waves they say prove that the universe expanded rapidly, less than a trillionth of a second after the Big Bang. Scientists are calling the discovery "smoking gun" evidence of a theory known as inflation that experts have been trying to prove for 35 years. We look at the discovery and its significance for science.
