The Opening of Time

The prevailing visual intuition in cosmology depicts time as an outward expansion from 
an initial point—a spiral or trajectory that grows, unfolds, and accumulates structure as it 
proceeds. In this paper, we propose that this visual framing is inverted. Time does unfold, 
but the unfolding occurs through progressive restriction rather than expansion. The 
admissible space of trajectories narrows over time, producing a convergent (inward) 
spiral in which structure, persistence, and irreversibility arise as consequences of 
tightening constraint. This correction does not revise existing physical descriptions of 
temporal unfolding; it clarifies the geometry implicit in observed phenomena such as 
vortices, gravitational horizons, nodal suppression, and black holes. We propose that 
the Big Bang corresponds not to an explosive origin but to the widest cross-section of 
admissible temporal structure—the opening of time—after which admissibility 
progressively contracts.
