And these materialist eternalists further claim that the celestial spheres are incapable of splitting, an opinion already voiced by Aristotle and his followers. They allege that any rupture would require a rectilinear motion, which they deem impossible for the outermost sphere because, in their view, no void exists beyond it. Yet even if their reasoning demonstrated anything, it would pertain only to the seamless, all-encompassing sphere and not to the spheres beneath it—how much more, then, when their premise itself is unsound? For rectilinear motion there is comparable to initially placing the spheres in the spatial regions they occupy—whether one chooses to call those regions a “void” or not—as has been explained elsewhere.
