Editing Axion (section)

=== Predictions ===
One theory of axions relevant to [[cosmology]] had predicted that they would have no [[electric charge]], a very small [[mass]] in the range from {{val|1|u=μeV/''c''<sup>2</sup>}} to {{val|1|u=eV/c2}},<ref name="peccei2008"/> and very low interaction [[cross section (physics)|cross-sections]] for [[strong interaction|strong]] and [[weak interaction|weak]] forces. Because of their properties, axions would interact only minimally with ordinary matter. Axions would also change to and from [[photon]]s in magnetic fields.
