When rotating a superfluid (such as $^{4}$He) below its critical temperature, sometimes quantized vortices pop up, depending how fast one rotates this superfluid. In the SVT model, they propose that the vacuum may be some type of superfluid (it's all a bit speculative). Assuming that this is true, and that the Universe is rotating, then quantum vortices should pop up. What role would they then have in this model?

    $\begingroup$ While I cant vouch for the answer, see mfc "This is normal if we consider quantum vacuum as a superfluid and fermions as quantum vortices in this superfluid as it happens in other superfluids" but also Michael Porter here on SVT $\endgroup$ Commented Feb 17, 2022 at 2:49

Pretty much anything and everything from subatomic particles to Black holes. SVT would be the Theory of Everything giving also answers to Dark Energy, Dark matter and quantum gravity as our visible Universe being defects of an omnipresent superfluid medium that we call "Vacuum Space". However, many physicists do not regard the fabric of spacetime being a medium. SVT has to be proven.
