We consider a bounded domain $\Omega\subset\mathbb R^3$ and a rigid body$\mathcal{S}(t)\subset\Omega$ moving inside a viscous compressible Newtonianfluid. We exploit the roughness of the body to show that the solid collides itscontainer in finite time. We investigate the case when the boundary of the bodyis of $C^{1,\alpha}$-regularity and show that collision can happen for somesuitable range of $\alpha$. We also discuss some no-collision results for thesmooth body case.
