A new study analyzes the most complete set of galaxy clustering data to test the CDM model.

CDM is the standard model of cosmology describing the universe's evolution, expansion, and structure.

It fails to account for phenomena like cosmic inflation, dark energy, and dark matter.

The research team's approach is new because they want the same underlying physics could explain these anomalies.

Data from upcoming galaxy surveys will provide clarity on these discrepancies.

We need to find out if we need a fundamental change in our understanding of large-scale structures in the universe, say Shi-Fan Chen and his colleagues.

The study was published in Physical Review Letters ( 2024 ).
