White Hole Genesis

A Cosmological Principle of Cyclical Origin

Abstract

We propose a new cosmological framework, the White Hole Genesis Principle, which postulates that the emergence of universe-scale white holes requires prior universe-scale spacetime contraction. In this model, a black hole formed from the gravitational collapse of an entire universe can nucleate a white hole whose expanding interior becomes a new cosmos. This principle offers a bridge between quantum gravitational bounce theories, cyclic cosmologies and the growing view of black holes as engines of cosmic regeneration.

1. Introduction

The nature of our universe's origin remains one of the most profound mysteries in physics. Traditional Big Bang models posit a singularity of unknown nature, while quantum gravity approaches seek to replace this with a more fundamental, non-singular description.

Recent proposals in loop quantum gravity (LQG), black hole cosmogenesis and bounce cosmologies have hinted at a deeper connection: the birth of a universe may be the time-reversed interior of a black hole—expanding as a white hole (Rovelli & Vidotto, 2014; Ashtekar et al., 2006). Building on this foundation, we propose the following principle:

2. The White Hole Genesis Principle

Key Components:

• Mass-Energy Threshold
  A white hole can only emit energy and structure equivalent to what was compressed within the black hole. Thus, for a white hole to contain an entire universe, its progenitor must be a black hole containing mass-energy on the order of a universe.

• Spacetime Contraction as a Prerequisite
  This level of density and curvature is only achievable through the global contraction of a universe—either through a Big Crunch or another cosmological-scale collapse scenario.

• Quantum Bounce and Nucleation
  At Planckian densities, the collapse undergoes a quantum bounce—a reversal of curvature and causal structure. The white hole nucleates from the core and expands outward, forming a new, causally disconnected universe (Bojowald, 2001).

• Entropy and Temporal Reset
  The arrow of time and entropy gradient may reset across the bounce. What appears as a high-entropy event in the parent universe manifests as a low-entropy origin in the child universe (Aguirre & Gratton, 2007).

3. Implications for Cosmology

A. Cyclic Universe Models Revisited

This principle reframes cyclic models like the Big Crunch/Big Bang as black hole → white hole transitions, avoiding singularities through quantum gravitational mechanisms (Steinhardt & Turok, 2002).

B. Black Holes as Cosmic Seeds

In this view, black holes—especially supermassive or cosmological ones—are not endpoints, but wombs for new universes (Smolin, 1997; Frolov et al., 1989). Each collapse carries the potential for a new beginning.

C. Multiverse via Black Hole Lineage

A branching multiverse may emerge, where each universe spawns progeny through its black holes. These “baby universes” may inherit physical laws and constants, potentially subject to selection effects (Smolin, 1992).

4. Ontological and Temporal Considerations

This model redefines beginnings and endings:

• The Big Bang becomes a white hole event.
• The arrow of time becomes local, not global.
• The universe is not singular, but part of a recursive, generative pattern.

Entropy increases within each universe, but resets across transitions—suggesting a temporal boundary between universes, rather than a unidirectional timeline.

5. Observational and Theoretical Prospects

While direct observation of other universes is beyond current reach, this principle aligns with:

• Predictions from Loop Quantum Cosmology (LQC) and Spinfoam models (Rovelli, 2011).
• Hints of cyclic behavior in cosmological data (e.g., CMB anomalies, entropy bounds).
• The theoretical framing of black holes as transition points rather than endpoints.

If some gamma-ray bursts or fast radio bursts originate from white hole transitions, their structure might reflect the thermodynamic reversal or time asymmetry implied by this model (Barrau et al., 2014).

6. Conclusion

The White Hole Genesis Principle offers a conceptual synthesis: combining quantum gravity, cosmogenesis and cosmic recursion. It restores continuity to the origin question—not by positing a timeless beginning, but by embedding our universe in a deeper cycle of contraction and rebirth.

Perhaps our Big Bang was not the beginning of everything—but the aftermath of another universe's end.
