That is easily settled. The average redshift of the stars in our galaxy is z≈0. That means the relative velocity is zero, which tells us that we move with the other stars around the center of gravity of our galaxy. A very small vertical motion (with respect to the galactic plane) wouldn't indicate a tangential path, only a slight oscillation in the path within the width of the disk.BMAONE23 wrote:I think though, that the arguement (query) is, are we actually traveling around the band of the galactic plane as part of the milky way (in synk with it), or are we just passing through the plane and currently happen to be in the middle of it (tangent to it).
I think i read somewhere that we are effectively circling the plane of our galaxy, but we are also moving from what i call the top of the width of the milky way to the other side of the width and then back up. (Few thousand years for a cycle, dunno the time per cycle) and that movement being induce by the star gravity above or under the solar system. We wobble in the width of the galaxy (If my english is right) while circling the galaxy. Quite chaotic i suppose.
It may also explain some major event happening to the earth over the ages since life exist on it and before.
