We present a theorists view on the challenge to reach in ultracold fermionic atom gases a quantitative agreement between theory and experiment comparable to elementary particle physics or universal critical exponents in statistical physics. If this can be realized, ultracold atoms could become a major testing ground for non-perturbative methods for complex many body theory. Universality amounts to a loss of memory of the microscopic atomic and molecular details such that the many body physics can be described in terms of a few effective parameters , comparable to the renormalizable couplings in quantum field theory. We present theoretical results for the BCS-BEC crossover based on the functional renormalization group. This includes the condensate fraction or the correlation length for effective bosonic bound states at zero or close to the critical temperature.
