Branch Lecture: The Dark Energy Survey and the beginning of an industrial revolution in Cosmology
The March IoP South Central Branch talk brings Prof Kathy Romer, Professor of Astrophysics at the University of Sussex to explain how almost 70% of the universe is an exotic form called dark energy...
After 14 billion years it would be reasonable to expect the expansion of the Universe to be slowing down. However, the Universe seems to have other ideas! During this presentation you will learn about the mysterious substance, know as dark energy, that physicists think is causing the Universe to rip itself apart. You will also hear about the 300-person strong Dark Energy Survey (DES) experiment. DES is the first of a new generation industrial scale international astronomy projects that have been funded to explore the physics underlying our accelerating universe. DES is using sensitive observations of the night sky to understand the properties of dark energy. The observations are being made from a mountain top in Chile using one of the largest digital cameras ever made. In just one snap shot it can capture an area larger than 20 full moons. DES is using four different methods to study dark energy, and all of them seem to be telling us that the Universe is being governed by Einstein's Cosmological Constant (not his "greatest blunder" after all!).
