The Universe has an interesting history: after the big bang matter was very evenly distributed. Small fluctuations in density did exist and the strongest over-densities grew under the influence of gravity to form galaxies and clusters of galaxies. This growth was opposed by the expansion of the Universe, which went through periods of acceleration and deceleration. Information about these periods and the physical process driving them is consequently encoded in the distribution of galaxies. By mapping the Universe as a function of look-back time (the time taken for the light from distant galaxies to reach us), we can understand this physics. The talk will start by reviewing distance scales and will look at making maps from galaxy observations. Science from these maps will be briefly considered, before wondering whether it would ever be possible to use these maps to navigate a journey across the Universe.\\n\\n \\n\\n \\n\"", "startDate":"2018-08-12", "endDate":"2018-08-12", "startTime":"19:30", "endTime":"20:30", "location":"School of Optometry and Vision Science Room 347 - 200 Columbia St W Waterloo ON N2L 3G1 Canada", "label":"Add to Calendar", "options":[ "Apple", "Google", "iCal", "Microsoft365", "Outlook.com", "Yahoo" ], "timeZone":"US/Eastern", "trigger":"click", "inline":true, "listStyle":"modal", "iCalFileName":"invite.ics" }
