Dr. Eliot Quataert (University of California, Berkeley)
Dr.
Quataert provides an overview of the modern understanding of our
origins in astrophysics. The story begins in the infant universe, which
we now know was remarkably smooth compared to what we see around us
today, with only tiny differences in its properties from one part to
another. By contrast, in the present universe there are enormous
differences in the properties of matter in different locations: some
regions host planets, stars, and galaxies (and even humans!) while
others are cold and mostly empty. Dr. Quataert describes how the
universe has evolved to its current state, emphasizing how gravity
reigns supreme and builds up the planets, stars, and galaxies required
for biological evolution to proceed
