A short flash talk from Peter Hatfield, Oxford Physics, who discusses the origins of the galaxies we see in our night sky and the mysterious nature of dark matter.
Heart of Darkness: The Interplay of Galaxies and Dark Matter
Galaxies are huge clusters of hundreds of billions of stars - the Milky Way is our galaxy, itself just one of many billions more. But even these are diminutive compared with the sea in which they swim, dark matter, an unknown substance we cannot see with our telescopes. We will look back in time over more than half the age of the Universe to see how galaxies sloshed about in this ocean of dark matter during their creation and development, hopefully helping us learn more about the galaxies we see today and potentially even something about the mysterious nature of dark matter itself.
