From Cambridge to Prague, and Beyond Einstein: Will Barker’s Quest for a New Gravity
Will Barker is part of a new generation of theoretical physicists reshaping how we think about gravity, black holes, and the fundamental structure of the universe. His recent research explores the strange frontier where Einstein’s general relativity may no longer hold — a region populated not by traditional black holes, but by their uncanny cousins: black hole mimickers. Since joining the Physics for Future fellowship in Prague, Barker’s work has taken on a broader scope. In this interview, he reflects on the role of uncertainty in physics, how cosmology can test bold new ideas, and why running to work through the hills of Prague has become part of his scientific routine.
