The problem with the latter being that there would be a wall, with the former that infinite space is hard to understand. Now the question: Is there a mathematical model for 3 accessible dimensions , this is what we 'perceive', in a higher-dimensional space that wraps around? Not that higher dimensions are easier to understand, nevertheless it could somehow 'explain' *seemingly* infinite space.
