Cyclones on Earth and spiral galaxies in space have several features in common. They both have spiraling arms coming out of a center that is hotter than their surroundings. The arms rotate almost as fast as the center, with rotating speeds falling off with distance from the center more slowly than is the case of vortexes and solar systems. The center of a cyclone pushes air up, and spiral galaxies are often seen to eject matter up and down perpendicular to their plane of rotation.

Conventional theory sees these similarities as purely coincidental. Cyclones are driven by difference in temperatures, while spiral galaxies are driven by gravity. Any electrical activity seen in cyclones in the form of lightning, and in galaxies in the form of plasma jets, are secondary to the primary drivers which are temperature and gravity.
However, the Electric Universe community sees this differently. Their interpretation is that cyclones and galaxies are primarily electric phenomena, with temperature and gravity playing secondary roles. The primary driver is in both cases charge imbalances, pulling light matter in towards a center from which it is subsequently ejected up and away. Cyclones pull air in towards their centers in the same way and for the same reason that galaxies pull plasma in towards their center. Heavier matter, such as clouds and rain, or stars and planets, are pulled along by the air or plasma currents while simultaneously thrown out to the sides by the centrifugal force. This produces the rope-like patters of the arms seen in both cyclones and spiral galaxies. The whole is driven externally from above and below.
This model of spiral galaxies requires no dark matter or dark energy to explain the rotation speeds of these bodies. It only requires the existence of plasma currents in space. Seen in this perspective, cyclones and galaxies look alike because they are essentially the same thing. Galaxies are as it were cyclones in space.
