AB  - The standard  Cold Dark Matter (CDM) cosmological model provides a good description of a widerange of astrophysical and cosmological data. However, there are a few big open questions that make thestandard model look like an approximation to a more realistic scenario yet to be found. In this paper,we list a few important goals that need to be addressed in the next decade, taking into account thecurrent discordances between the different cosmological probes, such as the disagreement in the valueof the Hubble constant H0, the σ8–S8 tension, and other less statistically significant anomalies. Whilethese discordances can still be in part the result of systematic errors, their persistence after several yearsof accurate analysis strongly hints at cracks in the standard cosmological scenario and the necessity fornew physics or generalisations beyond the standard model. In this paper, we focus on the 5.0 σ tensionbetween the Planck CMB estimate of the Hubble constant H0 and the SH0ES collaboration measurements.After showing the H0 evaluations made from different teams using different methods and geometriccalibrations, we list a few interesting new physics models that could alleviate this tension and discusshow the next decade’s experiments will be crucial. Moreover, we focus on the tension of the PlanckCMB data with weak lensing measurements and redshift surveys, about the value of the matter energydensity  m, and the amplitude or rate of the growth of structure (σ8, f σ8). We list a few interestingmodels proposed for alleviating this tension, and we discuss the importance of trying to fit a full arrayof data with a single model and not just one parameter at a time. Additionally, we present a wide rangeof other less discussed anomalies at a statistical significance level lower than the H0–S8 tensions whichmay also constitute hints towards new physics, and we discuss possible generic theoretical approachesthat can collectively explain
