Summary

Story summary

The study finds a mild preference for primordial magnetic fields as a factor in addressing the Hubble tension.
Researchers used three-dimensional simulations to track hydrogen formation and predict cosmic microwave background patterns influenced by these fields.
The findings indicate that if confirmed, these fields may reveal significant events from the universe's infancy and reshape cosmic evolution.
