Let me put it this way. A zero dimensional space is a point or a singularity.
In physics, a singularity is the situation where no physical laws apply.
In mathematics, the point corresponding to zero on the number line has restrictions on algebraic operations.
In euclidean and non-euclidean geometry, a point has meaning only relative to a fixed coordinate system in uniform or curved space.
In set theory, the null set is the only set wherein no set condition and all set conditions apply at the same time.
This void or absolute nothingness is queer, it has, at most, a fluid existence, it is an idea that has no manifestation in the real, common-sense world, and yet, it is necessary to any self-coherent logical conception.
