Sagan Day: Quantum Jitters in the Sky

Building 2, 2-190
182 MEMORIAL DR, Cambridge, MA 02139
"The passage from the Chaos of the Big Bang to the Cosmos that we are beginning to know is the most awesome transformation of matter and energy that we have been privileged to glimpse."
-- Carl Sagan, Cosmos
In celebration of Carl Sagan Day 2019, the Secular Society of MIT presents a special talk by MIT professor of physics (and of the history of science) David I Kaiser. Dr Kaiser co-directs a research group on early-universe cosmology with Alan Guth in MIT’s Center for Theoretical Physics, and has also designed and helped to conduct novel experimental tests of quantum theory. He will speak about the dramatic era of our cosmic history known as Cosmic Inflation, informed by the tiny, subtle patterns in the early glow from the big bang known as the cosmic microwave background radiation, and the insights thus yielded into the quantum state of the universe during its earliest moments.
WHEN: Wednesday, NOV/13, 7pm
WHERE: 2-190 (1st Floor, 182 Memorial Drive, https://whereis.mit.edu/?go=2)
Presentation followed by Q&A.
Free entry. Free apple pie and mocktail cosmos.
The event will be photographed and recorded.

Topic: Quantum Jitters in the Sky: The Big Bang, Cosmic Inflation, and the Latest Observations
Abstract: Physicists and astronomers have learned a lot about the earliest stages of our universe and how it evolved nearly 14 billion years ago, around the time of the "Big Bang." Several lines of evidence suggest that our universe underwent a very brief period of rapid, violent expansion, doubling in size every trillion-trillion-trillionth of a second, in a period known as "cosmic inflation." Cosmic inflation predicts several features of our universe today, from its shape and overall smoothness across vast distances, to the clumpiness we observe on shorter scales, ranging from the human-sized to the supergalactic. Major clues about this dramatic era of our cosmic history come from tiny, subtle patterns in the early glow from the big bang known as the cosmic microwave background radiation. Recent measurements have confirmed these predictions to high accuracy, yielding new insights into the quantum state of the universe during its earliest moments.
