Some museums collect objects.
This one collects boundaries.
The Arcade gathers mathematical, human, societal, perceptual, and temporal limits into a single navigable space.
It is not a claim of originality over centuries of philosophy.
It is a curatorial act.
Five wings. Five kinds of impossibility.
Each wing contains questions that look simple but resist resolution — not because we lack cleverness, but because reality itself is structured that way.
The mathematical wing is grounded in proven theorems: Gödel's incompleteness, Turing's halting problem, Matiyasevich's DPRM theorem, Rice's theorem. These results are not opinions. They are permanent.
The human, civilizational, perceptual, and temporal wings draw on philosophical traditions spanning 2,500 years — from Heraclitus to Derrida. These are not undecidable by proof. They are undecidable by nature.
This arcade does not claim to have discovered these questions.
It claims to have gathered them.
It claims to have named them.
It claims to have placed them side by side.
That is the contribution.
The Arcade is not a classroom.
It is not an argument.
It is a space for standing at the edge of what can be known
and looking outward.
