From the Kavli Foundation announcement . . .
"THE FIRST DEFINITIVE PROOF that the universe underwent an almost unimaginably fast expansion when it was only a trillionth of a trillionth of a trillionth of a second old has taken the world by storm. This sudden growth spurt was first theorized more than three decades ago. Yet only last month did astrophysicists reveal "smoking gun" evidence that the universe swelled from microscopic to cosmic size in an instant — an announcement that's being compared to the discovery of the Higgs boson.
"On April 18, two of the scientists who made this groundbreaking discovery will come together for a conversation with two of the pioneering leaders of the field. Together, they will examine the detection of a distinctive, swirling pattern in the universe’s first light, what the swirl tells us about that monumental growth spurt, and the many implications on the way we understand the universe around us."
