The Cosmic Microwave Background exhibits a remarkable cold spot—a region of unusually low temperature approximately 70 microKelvin colder than the average CMB temperature—located in the direction of the constellation Eridanus, with statistical significance around 3-sigma (meaning it would occur by random chance in only about 0.3 percent of simulations assuming the standard cosmological model). Lambda-CDM struggles to explain this anomaly because the model predicts that CMB temperature fluctuations should follow a Gaussian (bell-curve) distribution with no preferred regions or anomalous coldness, arising as they do from random quantum fluctuations during inflation amplified to macroscopic scales (Vielva 2004; Cai 2015). The cold spot's apparent non-random location, its unusual morphology with a sharp outer edge and complex internal structure, and its statistical improbability have led to various proposed explanations including void passages (light traveling through a cosmic void loses energy), supervoid geometry, topological defects from phase transitions, or systematic observational errors, but none of these explanations sit comfortably within standard Lambda-CDM without invoking either rare statistical flukes or new physics.
