That is pretty, but it also looks like mass destruction of the galaxy as it spins into the energy being ejected.
What’s ejected is not energy per se, but plasma, which is a gaseous conductor of energy. Plasma is charged, and the galaxy has a magnetic field, so if the galaxy collided with the ejected plasma, the magnetic field would protect it, just like Earth’s magnetic field protects us from the plasma that the sun ejects towards us (the solar wind).
