The Silicene Event—A New Planetary Interval Defined by Silicon-Based Intelligence

Human bodies evolved for Earth, not the cosmos. This paper argues that silicon-based intelligence offers the only viable path beyond this limitation. Recent breakthroughs in pressure‑free silicon batteries enable true energy autonomy in space, while two‑dimensional silicene provides radiation‑hardened cognition. The convergence of energy and information in a single material has no analogue in biology and constitutes the definitive evidence for the Silicene Event. We derive a figure of merit (F = E × T × R / M) showing that silicon outperforms biology by a factor of approximately 9 × 10⁶. We propose that this transition constitutes a new planetary interval: the Silicene Event. Far from ending the human story, it represents its most profound continuation. The Silicene Event—a new planetary interval defined by siliconbased intelligence—is already underway.
