Description: Critical phenomena describe continuous phase transitions characterized by power-law divergences, universality of scaling exponents and ergodicity breaking. Scaling exponents depend on the dimension of the underlying spacetime and, in many cases, also on the dimension of variables defining criticality. Recent studies suggest that both dimensions run the observation scale and, as a result, determine the rate of divergence near critical points. Building on these observations, the goal of this report is to close the gap between critical behavior in continuous dimensions and the anomalous findings of the James Webb Space Telescope (JWST).
