Summary

Story summary

Dynamic dark energy could significantly enhance galaxy clustering, according to research led by Associate Professor Tomoaki Ishiyama of Chiba University.
Using simulations on Japan's Fugaku supercomputer, the team compared dynamic dark energy with the ?CDM model.
The DDE model predicted up to 70% more massive galaxy clusters in the early Universe.
Results aligned closely with DESI observations, especially in baryonic acoustic oscillations.
The findings challenge long-held cosmological assumptions.
