Speaker's Night: The Dark Matter Universe

Dr. Sean Tulin, York University

In the Universe, about 15% of the matter is made of atoms, while about 85% is dark matter. The gravitational collapse of dark matter into a network of halos and filaments provides the cosmic foundation for all structure in the Universe to form. However, we have no idea what dark matter particles actually are, nor what their mass is, nor what interactions they may have. Dr. Tulin will discuss what is the evidence for dark matter, as well as his own research into how astronomy and particle physics can come together to solve this cosmic mystery.
