The universe has always fascinated scientists, and recent findings shed new light on the strength of magnetic fields in the early cosmos. According to new simulations, the very first magnetic fields in the universe were billions of times weaker than even the magnets on your fridge. In fact, these primordial fields were as faint as the electrical signals produced by human brain waves.
Despite their weakness, these magnetic fields played a crucial role in shaping the structure of the universe. They influenced the formation of galaxies, stars, and cosmic filaments. New simulations have allowed researchers to set the strictest limits yet on the strength of these fields, helping us better understand the conditions that led to the universe we see today.
What Does This Discovery Mean?
Scientists believe that understanding these weak magnetic fields can help explain how the universe evolved over billions of years. By mapping their origins and effects, we gain insight into the formation of cosmic structures and the underlying physics of our universe.
