Black Hole - White Hole Theory

Abstract

This hypothesis explores the possibility that our observable universe represents the interior spatial region of a black hole. Rather than considering the black hole merely as a compact mass embedded within pre-existing space, it is treated as an overarching spherical spatial structure whose internal geometry appears fundamentally different to an interior observer than to an exterior one. The hypothesis does not attempt to disprove General Relativity (GR). On the contrary, the empirically confirmed predictions of GR are intended to remain intact. The approach consists of re-evaluating certain geometric interpretations of GR and potentially supplementing them with an underlying spatial geometry. A central premise is that the fourth dimension might be interpreted not as time, but as a fourth spatial dimension. Observed gravitational time dilation could arise because matter and energy deform—or cause to "sink"—the three-dimensional spatial structure more strongly into this fourth spatial direction. The hypothesis is explicitly speculative and claims no empirical confirmation. Its value can lie solely in whether a mathematically consistent and experimentally distinguishable description of observed cosmology can be developed from its assumptions.
