Magnetic fields permeate the universe JPL; NASA/SOFIA/E. Lopez-Rodiguez; NASA/Spitzer/J. Moustakas et al.
We may finally know how the magnetic fields that now permeate the universe first arose. Much of the universe was once a churning unmagnetised plasma, and a new set of simulations shows how that plasma may have developed powerful magnetic fields.
at Columbia University in New York and his colleagues simulated turbulence in plasma to study a phenomenon called the Weibel instability. When a fluid is turbulent, asymmetries can develop when more particles happen to be moving in one direction than the others. These…
