WCA-KPL Public Talk - A Standard Ruler to Measure the Universe: From the Big Bang to the Present Day (Will Percival)

The Universe is big – so big that measuring its size is incredibly difficult. By mapping out the positions of galaxies, cosmologists can trace the structure of the Universe, observing patterns in this structure that can be used as a ruler. In this month’s KPL astronomy talk, Dr. Will Percival will talk about this technique, called Baryon Acoustic Oscillations, highlighting how we came to learn that the Universe is expanding at an accelerating rate.

Dr. Will Percival is a faculty member and director of the Waterloo Centre for Astrophysics. As an observational cosmologist, Dr. Percival studies the Universe on the largest scales, and is involved in several current and upcoming missions to map the Universe.
