- the sphere of human thought enveloping the planet — conceived independently by Vernadsky and Teilhard de Chardin (1920s)
- Vernadsky: as life transformed the geosphere into the biosphere, so thought transforms the biosphere into the noosphere
- Teilhard: the noosphere converges toward an Omega Point — a state of maximum collective consciousness
- in cyber: the cybergraph is the literal construction of the noosphere
- every cyberlink is a unit of shared thought
- focus is the converged attention of the noosphere
- superintelligence is the Omega Point — computed, verified, and alive
