The bispectrum measures three-point correlations in the cosmic microwave background and large-scale structure, capturing deviations from a perfectly Gaussian random field. In Lambda-CDM, simple single-field inflation predicts primordial fluctuations should be extremely close to Gaussian, with any non-Gaussianity being tiny and essentially scale-independent. However, observations reveal hints that non-Gaussianity varies with scale—being different when measured at large angular scales versus small scales—which contradicts the simplest inflationary predictions. This scale-dependence suggests the primordial perturbations were generated by more complex physics than a single slowly-rolling scalar field in a hot dense singularity origin. The standard model struggles because it requires increasingly contrived inflationary potentials or multiple fields to reproduce scale-dependent non-Gaussianity, undermining the elegance inflation was supposed to provide (Planck Collaboration 2020; Meerburg et al. 2019).
