Two of the Most Elusive Particles Might Interact. That Would Change Our Knowledge of the Universe.

Key Points:
- A new study suggests that interactions between dark matter and neutrinos could explain why the universe appears less "clumpy" than predicted by the Standard Model of Cosmology.
- Researchers analyzed cosmic shear data from early and late universe observations, including data from the Atacama Cosmology Telescope, Planck Telescope, Dark Energy Camera, and Sloan Digital Sky Survey.
- The study estimates the interaction strength between dark matter and neutrinos to be about 10^-4, potentially resolving discrepancies between early- and late-time measurements of cosmic structure.
- While the findings have a statistical significance of three sigma (3σ), which is not definitive proof, they may indicate that the current ΛCDM model is incomplete rather than incorrect.
- Future experiments and more precise
