The Primaverse is a canon that uses realism to attempt an explanation of how the Backrooms could exist. This canon also attempts to explain how the Backrooms, and possibly everywhere else, was and/or will be created. Basically, this is a canon trying to bind all of the ____rooms and universes together.
Noclipping
The way one travels between our universe and The Backrooms is via ‘noclipping.’ The definition of noclipping is “the action of travelling quickly enough to pass through a wall or any solid object.”[1]
