Editor’s note: New data have cast doubt on the interpretation of the BICEP2 data. For an update on this story, read Inflation, Elation, Deflation: Reflecting on BICEP2.
One of the most incredible physics discoveries of the century was just made. It reveals new secrets of gravity and the birth of our universe, called “inflation.” This video takes us back to the beginning of time and explains how quantum particles in the infant universe created a cosmic fingerprint that scientists can see today. This new evidence tells not only why the universe exploded outward during its birth, but also that gravity is made of quantum particles, called gravitons.
