Challenges of the Standard Cosmological Model

Measurements of the temperature and polarization anisotropy cosmic microwave background (CMB) provided strong confirmation vanilla flat ?CDM model structure formation. Even if this fits incredibly well, cosmological astrophysical observations in a wide range scales epochs, some interesting tensions between probes, anomalies CMB data, have emerged. These discrepancies different statistical significance, although parts may be due to systematic errors, their persistence strongly indicates possible cracks standard scenario.
