In this talk, we will explore a new type of invariants of supersymmetric quantum field theories that comes from stable homotopy theory. As a concrete application, I will demonstrate that the theory of topological modular forms can be used to rule out the existence of an infinite set of "extremal CFTs", including those with central charges c = 48, 72, 96 and 120.
