Although magnetic forces are usually much weaker than gravity in shaping cosmic structures, the findings suggest that strong, ordered magnetic fields may have emerged earlier than expected. Over time, ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...

Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory puts that timeline at roughly 5 to 10 billion years in galaxies. Yet ...

A new study suggests that collapsing plasma clouds during galaxy formation could explain how galaxies build large-scale magnetic fields far faster than existing theories predict. (Nanowerk News) How ...
