Other effects, such as light scattering from cosmic dust and the synchrotron radiation generated by electrons moving around galactic magnetic fields within our own galaxy, can also produce these polarisation twists.

Most galaxies in the universe revolve around central black holes, which feed voraciously on galactic gas and dust and spew out radiation.

The comparison clearly showed that the observed rotation can not be explained unless large amounts of dark matter exist around us, and between us and the galactic center.
