Do galaxies and black holes all spin in same direction?! CW or CCW?!?

Depends. Are you looking east or west?

There is an inexplicable tendency for galaxies near the WMAP Cold Spot to align and rotate in the same direction IIRC, but the direction something spins in depends on your orientation to it and the axes of galaxies are not parallel.

As a central mass draws in matter that becomes a galaxy, the Coreolis law sets up an orbit in one direction. You get star clusters, stars have much a random orbit,
Takes many millenia for them to stabilize like the Milky Way.

Neither. They all spin sideways.

Both. It depends on which side you're looking from.

The answer is yes
Any body that spins induces the Correolis effect
As in Earth itself, cold air falls and spirals to the right
So at the poles, as well as falling the air and the currents of the sea the effect sends them into a clockwise spiral
It drives our weather
It is the same rule from Earth to the Sun to the Solar System, the Galaxy or even Black holes
Of course, at the North Pole of the Body the direction because of the correolis effect it turns to the right, which is clockwise
At South Poles the rules are the same and they also turn to the right/ Clockwise but if you could compare it with the North pole, it would be turning in the opposite direction
If you look at Uranus, no jokes please, in the Uranian Summer it is at its Perihelion
Its South pole is towards us and reacting to the rise in radiation from the Sun
to our eyes it is also revolving AnticlockwiseSource(s): Electronics right hand rule of thumb, just the same as the Correolis effect, could be a link

If there are two galaxies near each other, there is a statistical tendency for them to have opposite spins, because, to the extent that their gravitational potentials have quadrupole moments, they will "spin each other up", even if the net angular momentum of the whole system (of two galaxies) has zero angular momentum.

Those galaxies that do spin in a preferred direction (like our own) have random orientations. Not just in direction, but also in inclination.
WE (humans on planet Earth) have decided to define the orientation of the spin axis based on the idea that from the "main direction" of that axis, the galaxy would appear to spin counter-clockwise (which, in mathematics, is the positive direction of a vector angle, on the x-y plot).
We applied this to Earth and have called Celestial North Pole the extension of the axis that allows that view of Earth.
Based on that orientation, as we climb higher and higher, we find that Earth would appear to rotate CCW, that the Moon orbits Earth CCW, that The Sun rotates CCW, that all major planets (and most of the rest of the stuff) orbits the Sun CCW (this direction is called "direct" or "prograde").
Within our Solar system, things that rotate or orbit in a retrograde direction do exist, but they are in the minority.
Based on that line (the line that extends northward from Earth), the Galaxy's spin would be retrograde (clockwise) and would appear to be tilted by sixty-some degrees.
From the Galaxy's viewpoint, we are the ones going the "other" way with a sixty-some degree tilt.
Of course, if you lived in Antarctica and decided to follow the southward extension of the Earth's axis of rotation, all directions would appear reversed.

Not all galaxies spin. They can be oriented any which way, the same for black holes, and solar systems.

CW or CCW have no meaning unless you have an orientation or a set of coordinates to view from. and even then, how do you class one that is seen edge on?
and two galaxies seen as CW spin from earth in opposite directions would have opposite spins if seen by someone on the other side of one of them.
and how could you compare one rotatiing galaxy with another orientated 90º with respect to the first?
they do spin, that's all you can say. Some do, some don't.
