Still she haunts me, phantomwise, Alice moving under skies Never seen by waking eyes. - Lewis Carroll
Name given to the sum total of all the various simulations, emulations and VR environments in existence across the Known Net at any given time.
Some of the oldest Inner Sphere VR creations (known as The Realities) have been in continuous operation for over 9000 years and claim to match or even exceed the complexity and scope of the 'real' universe. It is not at all unusual for entire planetary or solar civilizations to choose to emigrate to the Cybercosm or one of its Realities. The current immigration rate has held steady at 100-200 billion beings/year for the last several centuries.
As of the last census, it is estimated that the Cybercosm contains the equivalent of 1020 'universes' with some 1010 equaling the modosophont sensory fidelity of the 'realized' world and some 106 exceeding it. Cosms which appear to be more complex than the real universe are modelled using 'point of view' technology; the virtual universe is simulated to appear complex from the point of view of the observer, but most of the cosm exists only in low-resolution form.
The extensive simulated universes maintained by the Solipsist Panvirtuality are not included in the Cybercosm list, as very few of the Panvirtuality worlds allow outsiders to enter within, so almost nothing is known about them for certain.
Virchspace - Text by M. Alan Kazlev Any digital space or environment; pertaining to virch or a cybercosm.
Virchuniverse - Text by M. Alan Kazlev Generally, an aggregation or collection of thousands of interconnected virchworlds or cybercosms, all sharing the same basic ontology and lay-out, to make traveling from one to the other easier. Sometimes also used to designate a single extremely large virchworld.
