Inflation: A New Universe is Born with Alan Guth | MIT

source: Harvard University     2014年3月27日
Almost 14 billion years ago, the universe burst into existence. In the first fleeting fraction of a second it expanded exponentially, stretching far beyond the view of our best telescopes. Alan Guth developed the theory of cosmic inflation to describe the first moments of the universe. He summarized inflation at an event to celebrate the 50th anniversary of the discovery of the Big Bang (via detection of the cosmic microwave background). Part of the Observatory Night lecture series at the Harvard-Smithsonian Center for Astrophysics.

Everyone knows that the universe is huge, but no one could have imagined how staggeringly immense the universe, or multiple universes, may actually be. It stops your breath. How to get a measure of the size of the cosmos? What would it mean if the cosmos were literally infinite?
