Cybercosm based discussion forum employed by various transingularity minds to converse and perhaps argue about those questions and issues that are of long-term or theoretical interest to minds at SI:1 and above.
Multiple communication hierarchies and conceptual process support nodes allow the Noosphere to host users across the entire range of S-levels. Although the vast majority of the conceptual structures generated within the 'sphere are beyond baseline or superbright comprehension, it is rumoured that such ideas as the nature of the universe, its origins, and its possible future are but some of the topics 'discussed'.
The Noosphere is one of the oldest nodes within the Cybercosm and is even believed by some to have its roots within the 'Internet discussion groups' of the early and mid Information Age. Total active membership at any given time is estimated to be around thirty-three trillion although this number is uncertain due to the great flexibility of the definition of 'individuality' among many of the higher level members.
