Complex sentence: Our current standard view is that magnetic fields can hinder collapse, and that large-scale Birkeland currents have not been observed and the length scale for charge neutrality is predicted to be far smaller than the relevant cosmological scales.
Split into simpler sentences: Our current standard view is that magnetic fields can hinder collapse. However large-scale Birkeland currents have not been observed and the length scale for charge neutrality is predicted to be far smaller than the relevant cosmological scales.
