The universe is a cake; void, atmosplane, ocean, crust, mantle, molten liquid, iron slab, all held together by the slab's magnetogravitic field. They all extend out to infinity along the x and y axes, while the void extends into infinity along the upper z axis. Landmasses worthy of a real-world terrestrial planet, called toli (sg. tol), dot the endless ocean like islands - brought up above the surface of the ocean because of the all-important metaparticles, finicky little subatomic particles that can transmute into any other particle.
