Our Universe began almost 14 billion years ago as a hot soup of energy and elementary particles. With modern telescopes we can peer back into the distant past and see the Universe as it was at early times, before the first stars and galaxies lit up the sky. We’ve learned that on the largest scales the Universe can be described by a few simple numbers, but on smaller scales incredible complexity arises. I will discuss the major observations that have led to this picture, with a focus on the evidence that our Universe is dominated not by the stuff that we can observe, but by dark matter and dark energy whose nature is still unknown to us.
Join Laura Parker in conversation with Katie Moisse for this online webinar exploring our universe.
Laura Parker is a professor in the Department of Physics & Astronomy at McMaster University. Her research group is interested in questions related to galaxy evolution and observational cosmology. In particular, her group is trying to understand the connection between observed galaxy properties and the properties of the environments in which we find them, including the relationship between galaxies and their host dark matter halos.
Katie Moisse, Assistant Professor, Interdisciplinary Science, completed her undergraduate degree in Kinesiology at the University of Waterloo, her Masters in Neuroscience at King’s College London, and her PhD at Western University in Pathology. She was then accepted into Columbia University’s Graduate School of Journalism, interned at Scientific American, reported on health and medicine for ABC News in New York for four years and then edited stories about neuroscience and autism at Spectrum. Katie joined McMaster in January 2018 where she’s an Assistant Professor with the School of Interdisciplinary Science.
