The Hubble Tension: Could Primordial Magnetic Fields Explain the Expanding Universe?

Astronomers are grappling with the Hubble tension—a major conflict in measurements of how fast the universe is expanding.

Data from the cosmic microwave background point to a slower rate, while supernova observations suggest a faster one. New research proposes that primordial magnetic fields from the early universe may have influenced hydrogen formation and altered cosmic expansion.

Recent simulations indicate these ancient magnetic effects could help reconcile the discrepancy, offering fresh insight into the physics of the infant universe and the origins of cosmic structure.
