The Milky Way is in a sort of orbit around the center of the Local Group which is the name for the local group of galaxies. It’s not a clean circular orbit and it’s not possible to calculate the rotation time, because the pull from other galaxies is stronger than their collective centre of point of gravity, but sure, it rotates overall on that scale too.
The next levels are different. The Local Group is part of a larger supercluster of galaxies that do not seem to rotate. It’s more like flows of galaxy clusters. Depending on the point and scale we look at, it may be shrinking or expanding.
Perhaps there is some rotation to it, but the scale of both distance and time is so incredibly large that it’s meaningless.
unfortunately i feel you can’t call yourself spacefaring unless you actually control the ship, and we have about as much control over our trajectory as a mosquito has control over the amount of blood inside a blue whale
Well, technically speaking, we all are in space.
We are all passengers on a generational space vessel.
We need a better navigator, though. We keep going around in circles.
The Sun isn’t stationary 😉
Nobody said anything about writing on it.
but it also goes around in circles, or maybe it’s more of a spiral
The Milky Way isn’t stationary 😉
another circle maybe? does anyone really know?

sounds like they spent a lot of time coming up with that name
jokes aside, thanks for the interesting info!
Are we technically a space fairing civilization?
