Epistemic note
This project constitutes a deductive structure based on constraints and invariants, not a philosophical hypothesis nor a physical theory. Its contents are not evaluable in isolation: each individual page presupposes the full conceptual structure of the site. Any judgment formulated without examination of the complete context is necessarily partial and non-conclusive. The distinction between structural deduction and interpretation is an integral part of the model.

We Are Mendeleev

Just as Dmitri Ivanovich Mendeleev intuited the missing elements of the periodic table, the Sphere of Everything arises from the awareness that what we observe is only a part of a much larger whole.

The classical periodic table: an effective representation, but not a definitive one.

The flat table is an effective tool, but it represents only a portion of what is possible. If periodicity suggests curvature, then the sphere becomes a natural hypothesis: a form capable of hosting both what is visible and what has yet to be explored.

The Cilindric periodic table: an effective representation, but not a definitive one.

From this perspective, even a three-dimensional arrangement suggests that what we call a “limit” is nothing more than the effect of projecting a broader structure onto a plane.

The hemisphere: one half visible, the other still to be explored.

In this vision, what we call “missing” is not absence, but potential continuity. Matter and antimatter emerge as two complementary halves of a single geometry.

We do not propose a definitive truth, but an invitation: to consider knowledge as a fragment of a larger structure, still in expansion.
