Does the universe as a whole have an orbit?

I know it’s expanding- but does it have a rotation? Our planet orbits our sun, which orbits our super massive black hole… it seems like rotation is the standard. So does the universe as whole have a spin? And if not why?

Orbit usually means traveling around something else. Since the universe is "everything there is". It can't be orbiting anything else.

Rotating (like spinning) would mean there is a center or an axis of rotation. At the broadest scale, the universe is isotropic (the same in all directions), which it wouldn't be if there was a spin (the direction towards the axis/center would be markedly different from the rest).

So: No, it doesn't.
