THE ETERNITY CLOCK

---

 In 1947, the Bulletin of the Atomic Scientists created the Doomsday Clock to warn humanity how close we are to global catastrophe. The Eternity Clock is its conceptual mirror.
Where the Doomsday Clock points toward the end of existence, the Eternity Clock points toward the eternal continuation of existence.
One tracks collapse. The other tracks coherence.
Both speak to our shared future, but from opposite directions - and on the Eternity Clock, our collective objective is midday, the symbolic horizon of lasting, enduring existence.

The Eternity Clock is part of the wider Define Health initiative, which explores health as the coherence that sustains life. If defining health helps us understand how existence continues, the Eternity Clock invites us to imagine how far that continuity can reach. Together, they reflect the same mission: to explore what helps life endure, individually and collectively.

It symbolically represents humanity’s progress toward the theoretical horizon of eternal existence - a state where biological, technological, social, and ecological coherence could support life indefinitely.

It integrates advances in:

• Biological longevity
• Regenerative medicine
• Cellular reprogramming
• AI-accelerated science
• Cognitive preservation
• Environmental stability
• Social and relational coherence

• ecological instability
• geopolitical tension
• uneven access to innovation
• social fragmentation
• institutional inertia
• ethical uncertainties

We stand within sight of the horizon — but not yet at its threshold.

The clock can move forward or backward depending on the coherence of our actions, individually and collectively.
