What Happened Before the Big Bang? | An Infinity of Worlds - Will Kinney (#224)

Will Kinney is a professor in the Department of Physics at the
University at Buffalo, SUNY, where he has been on faculty since
2003. Dr. Kinney's research focuses on the physics of the very
early universe, including inflationary cosmology, the Cosmic
Microwave Background, Dark Matter, and Dark Energy. He has authored
more than seventy published research articles and received the SUNY
Chancellor's award for excellence in teaching in 2014. In his
new book, An Infinity of Worlds, physicist Will Kinney explains the
theory that may hold the answers to these questions such as Why is
the universe so big? Why is it so old? What is the origin of
structure in the cosmos? It may even explain the ultimate origins
of the universe. The theory of cosmic inflation, before the
primordial fire of the Big Bang. Kinney argues that cosmic
inflation is a transformational idea in cosmology, changing our
picture of the basic structure of the cosmos and raising
unavoidable questions about what we mean by a scientific theory. He
explains that inflation is a remarkable unification of inner space
and outer space, in which the physics of the very large (the
cosmos) meets the physics of the very small (elementary particles
and fields), closing in a full circle at the first moment of time.
With quantum uncertainty its fundamental feature, this new picture
of cosmic origins introduces the possibility that the origin of the
universe was of a quantum nature.  Kinney considers the
consequences of eternal cosmic inflation. Can we come to terms with
the possibility that our entire observable universe is one of
infinitely many, forever hidden from our view? Get the book:

include: What does inflationary theory say about cosmogenesis? Does
inflation require a singularity? Alternative theories to cosmic
inflation Is inflationary theory "dangerous"!? Why Paul Steinhardt
is wrong! There is no single theory of inflation so how do you
classify and think of it as a concept? What evidence would cause
you to doubt inflationary theory? For example the topology of the
Universe? What other tools can prove or refute the multiverse?
