A telegram from the early Universe? Professor Marc Kamionkowski - Johns Hopkins University
In March 2014, a small group of scientists working at a new observatory at the South Pole announced the detection of a new relic from the early Universe. The observations they made were of a particular pattern in the cosmic microwave background, the remnant heat left over from the Big Bang. These results are interpreted as a propagating ripple in the fabric of spacetime created within the first trillionth of a trillionth of a trillionth of a second after the Big Bang. If this result holds up, it will likely come to be viewed as one of the most significant advances in cosmology in several decades. Some cosmologists, however, still need more information to be convinced. Dr. Kamionkowski will explain what these scientists may have found and what still needs to be done to establish the results more firmly. He will explain the implications for our understanding of the origin of the Universe, and where we go from here.
