Hello, this is my first topic/question, thanks for reading thus far... It is very easy to find explanations about the general path that the solar system takes when it orbits the center of our galaxy, when viewed in 2D from above, a circle around the center some distance away from that center, and how fast we're moving relative to other distinctive galactic features. But I've also read that the path takes us up and down relative to the galactic equator, in kind of a sine wave patterh when viewed in 2D from the side. I've also read that the "bobbing up and down" is the result of a spiraling path taken by our solar system. So the 2D path viewed from above like a bicycle tire around the hub, but then the 3D path is as if you replaced the bicycle tire with a slinky wrapped around the rim. Is this depiction correct? If so, why a spiral? Are are we spiraling around something, some larger thing that is moving near the galactic equator that our sun and its system is orbiting? I'm really curious about this, particularly if our angle on the up or downswing ever gets us high enough above the dust cloud at galactic equator to see the center. thanks again for reading and any answers.
