Do all galaxies spin in the same direction?

[SMOGZINN]

indeed, it all depends on perspective - the spin direction is different from the "top or bottom". a deeper question that bothers me though is:

1) is the spin of planetary revolution around a star in the same direction of the galaxies they inhabit?

2) also, is the distribution of planets' rotations in a solar system related to the planetary/galactic orbital direction?

No to both questions. Solar systems appear to be pretty much distributed at random in respect to their rotation compared to that of our galaxy. Our solar system is tipped 63 degrees in respect to our galaxy, which goes to show that they don't even align to the galactic plane.

EDIT: Quick google shows this link

Tnx for ur reply. However that link states that solar planes are distributed at random with respect to their galactic plane. I was thinking more about their angular momentum. are the rotational directions also distributed randomly. In our solar system Most of the planets do rotate counter clockwise as seen from north ecliptic pole - except for Venus (clockwise), Uranus (rotates on its side) and Pluto (which points slightly down). However I am not an astronomer so I do not know if this is the norm.

Think of a solar system exactly lined up with the galactic plane, with rotational direction also aligned with the galactic plane. (for example both spinning clockwise as viewed from galactic north)

Now turn that solar system 90 degrees. It's rotational direction is now north-south. Turn it another 90 degrees and it is spinning counter clockwise.

Since the solar planes are randomly arranged, so is their apparent rotation.

Edit: Maybe what is confusing you is the idea of UP. there is no way to tell if a star is right side up or up side down, nor is there any difference.

I understand about the random distribution of the relative angles of the ecliptics. And I understand how that randomization will scramble any conclusion about orbital direction IF these two variables are independent. However, consider the possibility that these two variables (relative ecliptic angle, orbital direction) are not independent. If orbital direction in some way is related to relative ecliptic angle (perhaps as a result of how the galaxies/solar systems were formed), then we might find that orbital directions are more frequently aligned (I know I am not expressing this well but I need to draw a pic and this board does not allow that) Another way to ask the question would be: is the reflected light from planets doppler shifted in the same way when the planets are seen to be on the same side of their star?

From my basic understanding of the universe, all the solid objects are just hovering due to the fact that space itself has no gravity, only the objects do. They can move in any direction they want, so depending on what happened at the creation of a group of objects, it just continues on in the last direction they were pushed or pulled, and the various gravity pulls from other objects and itself keeps them going that direction.

So everything is completely random based on the last time an energy force caused it to change it's movement. Place a bunch of balls in water and throw something at them, they'll all go off in their own direction, some spinning clockwise or counter clockwise, or hardly spinning at all. So space is basically this but in 3D and way less resistance. At least that's my theory, without doing any research.
