The Big Bang, Black Holes, and The Opening of Time

Modern cosmology is often narrated as a story of beginnings: a universe that starts, expands, cools, and structures itself over time. At the centre of this story sits the Big Bang, commonly described as an initial explosion from which space, time, and matter emerge.

Yet this language conceals more than it explains.

An explosion presupposes a background into which something expands, a force that drives separation, and a causal asymmetry between what exists before and after. None of these assumptions are well-defined at the origin of spacetime itself. As a result, the Big Bang is frequently treated as a singular exception to otherwise coherent physical reasoning — a necessary but conceptually unresolved boundary.

Black holes occupy a similar role at the opposite extreme. They are described as endpoints: regions where spacetime curvature diverges, information becomes inaccessible, and familiar descriptions fail. Like the Big Bang, they are framed as pathological limits rather than structural features.

This paper advances a different perspective.

Rather than treating the Big Bang and black holes as anomalous events or breakdowns of physics, we interpret them as temporal boundary conditions arising from the same underlying geometric structure. In this view, neither represents an explosion or a collapse in the conventional sense. Both instead mark limits of admissible temporal evolution within a structured container.

The aim of this paper is not to replace existing cosmological models, but to reframe their most problematic elements in structural terms: geometry before force, constraint before dynamics, and time as the primary ordering principle.
