Detection of B-mode Polarization at Degree Scales Using BICEP2 - J. Bock - March 20, 2014

Jamie Bock, Professor of Physics at Caltech and Senior Research Scientist at the Jet Propulsion Laboratory, presents results from the BICEP2 team on the first direct evidence of inflation and primordial gravitational waves.

The team measured a B-mode polarization signal in the cosmic microwave background using the BICEP2 telescope at the South Pole. This signal is an important confirmation of key aspects of the theory of cosmic inflation, about how the universe may have behaved in the first fractions of a second of its existence to create the universe we live in today.
