The Past
The Past is everything that is occurring, at every point in the Space-Time Tube behind the bleeding edge. The Past may be distinguished from The Future which is pure and unrealized potential, and The Present which is all events that are occurring at the front edge of the Space-Time Tube.
Given the nature of the Space-Time Tube as the manifested Thought and Intent of God, The Past is malleable, to a point. Intent may be directed towards modifying energetic conditions at any point in The Tube, with "recent" points (i.e. points close to your physical and temporal location) being easier "targets." Keep in mind however that The Past has already been created and thus energetic inertia and pre-existing structures make modification difficult. Collective attention directed at specific points can, however, have noticeable ripple like impacts.
