Most
astronomers believe that our universe began with a violent explosion,
nicknamed the Big Bang. One of the strongest indications that this theory
is true comes from the detection of very faint radio wave emission from
all parts of the cosmos. Such radio signals, remarkably uniform as viewed
from any direction, are thought to be the remnant radiation from the
origin of the universe - an echo of the Big Bang itself. These radio
signals make up the cosmic microwave background. Dr. Bernard will explain
how these microwaves are linked to the Big Bang, and how the study of
these ancient radio signals may reveal the structure and shape of the
universe of today.
Dr .Claude Bernard is a Professor of Physics at Washington University.
His research interests lie in the areas of particle physics and computational
physics.
