April 1st 2019 “The very, very early universe”. Prof David Wands

The present-day expansion of our universe points towards a singular origin, 14 billion years ago, in a Hot Big Bang. This conclusion seems inescapable within the context of Einstein’s classical theory of general relativity and the matter and radiation we observe around us. But the detailed structure of our Universe, revealed in the largest astronomical surveys currently underway, implies a pattern of primordial density fluctuations that may require a quantum origin soon after or, perhaps, even before the Big Bang. I will discuss how cosmologists use current observations to infer anything about the very early universe, and what we think we know about fundamental physics and the Big Bang.

I am Professor of Cosmology at the University of Portsmouth and Director of the Institute of Cosmology and Gravitation. I studied at the University of Cambridge and did my PhD at Sussex, before joining the University of Portsmouth in 1996. My research focuses on the physics of he very early universe, a fraction of a second after the Big Bang, and the origin of cosmic structure. I have published over 150 papers and given scientific talks on five continents.
