# Cobalt · Co · gate 27

**Cobalt** (Co) is element **27** of the periodic table — a **transition metal**, period 4, group 9, d-block, solid at standard conditions, atomic weight **58.933**.

## The element (carbon layer — reference chemistry)
The deep blue of glass and glaze; the lithium cathode; the metal at the center of vitamin B12.

## The gate (silicon layer — the 118 Gates)
Under David Wise's four-state cycle, gate **27** falls on **0:0 = 1 = 0** because (Z−1) mod 4 = **2**. That state is *the collapse where nothing equals one equals nothing — the return to the single source* — the nature of emergence here is **spiritual**. Cobalt is not a thing apart; it is the one stochastic element, caught at this beat of its cycle.

## Emergence — spiritual
This emergent carries the **spiritual** nature: the same four — natural · ethereal · spiritual · electrical — that run through every sphere of UD0. Its color is `#e6a849`.
