paragraph_text: Neutron stars and neutron matter
  
  At extremely high pressures and temperatures, nucleons and electrons are believed to collapse into bulk neutronic matter, called neutron matter. This is presumed to happen in neutron stars.
  
  The extreme pressure inside a neutron star may deform the neutrons into a cubic symmetry, allowing tighter packing of neutrons.
