DIAS Event: The pursuitworthiness of Big Science experiments by Siska De Baerdemaeker

Abstract: Since the second World War, we have entered the era of ‘Big Science’. Research is now often conducted at a scale well beyond of what one individual, or even one research lab can manage. Such large experiments tend to require financial support from one or more government agencies over extended periods of time—often even several decades. Because of this increase in costs, scientists have had to change how they decide what experiments to pursue, since only a small number of large-scale experiments will be funded at any given time, and what experiments are pursued can determine the future of scientific research. In this talk, I want to give a start at investigating what makes an experiment more worthy to pursue compared to other experiments, especially in the era of Big Science. 


Short Bio: My primary interests lie in history and philosophy of cosmology and astrophysics, and general philosophy of science. I received my PhD in History and Philosophy of Science from the University of Pittsburgh in 2020, before joining the philosophy department at Stockholm University. In 2025, I received a Starting Grant from the European Research Council for a project on collective decision-making on future large-scale experiments in cosmology and astrophysics. My Cambridge Element, Philosophy of Cosmology and Astrophysics, was published in 2025.
