But rotation direction depends on the observer. If i see galaxy spinning clockwise, this means someone observing galaxy from behind it sees it rotating counter clockwise. So are we just located so in the universe that we see 2/3 spinning clockwise and another counter?
this is a hard one for me to instinctively understand spatially, so I’m imagining myself stood in a room with arrows pointing left and right. if I have 3 arrows facing left in front of me and behind me I have 3 arrows facing left -- from my perspective when I turn around -- then I step past one of the arrows and now I have 2 left facing on one side and then in front of me what was now a left arrow is a right arrow, so now there's 5 lefts and 1 right. so extrapolating that, the observation is possible, but it still doesn't explain the imbalance, does it? you would expect most places in the universe to have a roughly even distribution from any perspective, I think?
