By adding primordial magnetic fields to the Standard Model, researchers may solve the mystery of the Universe’s expansion.

Scientists have suggested a way to resolve a longstanding paradox known as the Hubble tension by taking primordial magnetic fields into account, which may have been generated in the early moments of the Universe.

“Primordial magnetic fields are the fields generated in the early Universe, such as during inflation, phase transitions, and other processes,” explained Yaoyu Li, a physicist at the Purple Mountain Observatory in China and one of the authors of the study. “These magnetic fields might evolve with the expansion of the Universe, be amplified and subsequently become galactic magnetic fields that we observe today.”
