The stars in all galaxies must move otherwise they would fall toward the center and create a gigantic black hole. By spinning, galaxies avoid that fate. Some irregular galaxies exist with stars going every which way. Gravity makes some stars give energy to other stars so some will fall toward the center of those galaxies. That might make irregular galaxies start spinning. Nobody knows, but irregular galaxies should have a whole lot more stars drop toward the center than happens in a regular galaxy. That should make the black hole spin. A black hole gives off tremendous gravity. It gives off more as stars fall into it. That should start the galaxy spinning.
I'm not sure, but I will go out and check. I will be back in 47,810,364,690 years (estimated).
All seriousness aside, chirality or spin is important in the universe (and magic), but directionality is dependent on orientation and symmetry. If _I_ spin, I have a top and bottom, so I spin either clockwise (righty) or counterclockwise (lefty). The water in a toilet or sink also exists in a top/up bottom/down matrix, so we can determine directionality of the downward swirl of the water. The direction of the draining water varies depending on whether it occurs in the Northern or Southern Hemisphere of the planet.
But for objects that are symmetric with regards to up/down, top/bottom, such as planets, galaxies, and other round objects, the direction is still there, but it depends on which side of the object you're looking at. Look at the Earth. Normally we look at it with the Arctic at the "top". So it spins counterclockwise (lefty). But turn it upside down, with the Antarctic as the "top", and now it appears to spin clockwise (righty). Same with galaxies. Neither side is top or bottom, it just depends on your view. And galaxies themselves are skewed in all different orientations as they're strewn throughout the universe. Like spinning cosmic pancakes.
So, to answer your question, yes.
The spinning of galaxies is in three-dimensional space. If you look at a galaxy from one side, it spins clockwise. If you look at the same galaxy from the opposite side, it spins counter-clockwise.
Galaxies spin in all different directions.
Some galaxies even spin in different directions within themselves.
Galaxies move in different directions - clockwise and anticlockwise. Some even rotate differently within the same galaxy.
Direction of spin is dependent on the direction of the rifling on the inside bore of the barrel. A bullet will spin the same direction as the rifling.
Does spinning water always spin in the same direction?
The direction of the Earth's spin and the direction of the Moon's orbit is the same - counterclockwise
They don't. Uranus spins on a "sideways" axis with retrograde spin. Venus also has a retrograde spin. Most spin in the same direction though. This is probably because of how the Solar System was formed, from a spinning disc of material.
Both
Yes it does no matter what.
Most, but not all, spiral galaxies rotate in the same direction - clockwise as seen from Earth.Some, like the Black Eye Galaxy, have an inner region that rotates in the opposite direction to the outer region.
No, most tornadoes in the northern hemisphere spin counter clockwise, while most in the southern hemisphere spin clockwise. Additionally about 0.1% of tornadoes spin in the "wrong" direction for their hemisphere.
The outer electrons do not spin in all the same direction-
The gravitational effects. For example, gravitational lensing; also, galaxies spin way too fast for the amount of known matter.
I am not sure what you are asking here, So I will try my best at guessing. Why does the earth rotate in the direction and the way it does, and all of the other planets rotate in the direction as well, and all of the planets orbit in the same direction around the star. All orbiting the same way. The milky Way Galaxy spirals again in the same circular orbit direction. I too wondered why does everything spin, rotate, orbit, in the same direction. Like a lot of science, This is only a theory, The theory I find that makes sense to me, is atoms and electrons spin in this way, If this spin conserves momentum, then our solar system, and galaxy, and all other galaxy's in the universe will spin the same. An interesting thought?
No. This is a matter of choice. They may spin in whichever direction they desire.
