This is a very old thread, but a very interesting one too, so I am going to resurrect it.
The way hurricanes organize themselves on Earth and even the red storm on Jupiter are swirling in a vortex not because of currents, but because of how
gravity organizes the currents when there is a vacuum present. Be it a vacuum of matter, dark matter maybe making a hole in the framework of space
creating a blackhole at the center of a galaxy for instance, or gases on a planet where a low pressure exists. The direction of the spin depends on
rotation of another influence such as a planet which is rotating or the Universe that might be rotating in a particular direction and so the galaxy is
rotating in the same direction as the Universe would be spinning. That's the leading edge of any galaxy moves back against the outer edge of the
Universe like a hurricane does in the northern hemisphere against the equator as the Earth rotates east to west.
I use "maybe and "might" because cosmology is still in the dark ages and has not discovered yet that the Universe is in deed rotating.
NOTE: All galaxies move in the same direction when viewed from the same perspective. You can figure this out by locating the general curve of the
outer most parts of the observable universe. Then see if the leading edge of all galaxies move toward it on the same side of rotation, and they all
do. That means the Universe is rotating in the direction that all galaxies turn into as the stars pass by the direction of the general direction the
universe is expanding out into.
