What is the Universe made of?
by Rogério Rosenfeld of Universidade Estadual Paulista (São Paulo, Brasil)
Our understanding of the Universe has been revolutionized in the past few decades. Several experiments with cutting-edge technology combined with solid theoretical models have provided a consistent, albeit somewhat unfamiliar and surprising, answer to the question of the title of the talk. We know that we don’t know what constitutes nearly 95% of the Universe. In this colloquium I will address the evidence that we have for this astonishing conclusion, focusing on the role of galaxy surveys such as the Dark Energy Survey, that has collected data for around 300 million galaxies that is being used to find out what is the best mathematical model that describes our Universe.
