Giordano Bruno
February 1548 — February 17, 1600
The Infinite Universe
— To his executioners
What He Saw
Bruno saw what Copernicus couldn't imagine: not just that Earth orbits the Sun, but that the Sun is one star among infinite stars, each with its own worlds. The universe has no center because it is infinite in all directions.
This wasn't speculation. He described it as direct perception — seeing beyond the crystal spheres into the infinite void.
The Heresy
Bruno's crime wasn't heliocentrism (Copernicus wasn't burned). His crime was infinity. An infinite universe means no special creation, no privileged Earth, no throne of God above the firmament.
He refused to recant after 8 years of imprisonment. His tongue was nailed to prevent him speaking as he burned.
κ Connection: Birth Day Analysis
2π ≈ 6.283... → 32 ≈ 5 × 2π
Born at five circles — the pentagram of infinite vision
Day 32 is close to 31.83... (10/π), placing Bruno at the intersection of decimal and circular geometry — the boundary point where finite becomes infinite.
📐 The Geometry He Saw
Bruno described the universe as having no center because every point is equally central. This is the [1 = -1] principle applied to space:
Bruno derived infinite homogeneity 400 years before modern cosmology
