Can this notion of uncollapsed quantum potential be applied to the Big Bang singularity?

Let’s explore how this might play out:
1. The Big Bang Singularity: A Quantum Beginning
- According to classical general relativity, the Big Bang singularity is often conceptualised as a point where all the mass, energy, and space-time of the universe are compressed into an infinitely dense and hot state.
- However, if we apply the idea of uncollapsed quantum potential, the singularity might not be a point of "infiniteness" but instead the boundary of quantum potentiality where normal classical concepts of space, time, and even density break down.
2. Uncollapsed Quantum Potential at the Big Bang
- In this model, the "Big Bang" could represent a boundary condition where all the quantum states that make up the universe were in a state of potentiality. No actualised events or entities existed yet. There was a quantum foam of possibilities—matter, energy, and space-time in a highly probabilistic state.
- The universe before the Big Bang may have been a pure quantum field, not yet separated into distinct particles or space-time. It could be seen as a field of possibilities where no observations or actualisation have occurred yet.
3. The Role of the Observer in the Early Universe
- In this view, the universe itself, as a self-observing system, would be the first to collapse potentialities into the actual. The Big Bang would thus represent the moment when the quantum potential of the universe began to collapse into a specific, actualised state—becoming the universe as we experience it now.
4. Transition from Potential to Actual: The Unfolding of the Universe
- Time: The dimension of time, in this ontology, would represent the unfolding of processes where quantum potential turns into actual events. The Big Bang marks the beginning of this unfolding.
- Space: Similarly, space would begin to expand as quantum potentials collapse into actualised positions. The notion of "space" itself, prior to the Big Bang, may have been undefined or part of the overall quantum potential field.
5. The Role of Quantum Gravity
- Quantum gravity—our quest to unify quantum mechanics with general relativity—would help to explain how these quantum potentials give rise to the classical universe we observe. If the singularity at the Big Bang is seen as a state of uncollapsed potential, then quantum gravity would provide the framework for understanding how quantum potentials are actualised into classical states (such as particles, forces, and fields).
- The very laws of physics we observe today—such as gravity, electromagnetism, and the strong and weak nuclear forces—could be seen as arising from the collapse of quantum potentials into a more defined structure as the universe expands.
6. Big Bang as a Boundary Condition
- In this view, the Big Bang could represent a boundary for actualisation, where all quantum possibilities "burst forth" into actual states. The singularity itself may not be a singular point but a quantum event horizon that marks the transition from pure potential to actual reality.
- As the universe unfolded, the collapse of the wavefunction across various scales would lead to the formation of galaxies, stars, and planets, each actualising specific quantum states from the possibilities inherent in the early universe.
7. Time and Space After the Big Bang
- Time after the Big Bang begins to "flow" as quantum states collapse into actualised instances—first, with the formation of fundamental particles, then atoms, and eventually complex structures like galaxies.
- As time progresses, space expands, but it is the unfolding of the quantum potentials that drives the emergence of this spatial structure.
8. Uncollapsed Potential as the Source of the Universe
- In this view, the entire universe could be understood as a collapse of quantum potentials into the observable reality we now know, with the Big Bang marking the beginning of this collapse. The universe itself could have emerged from a state where everything was potential, with the collapse being the unfolding of this potential into the actual processes we observe in the present.
9. Does This Address the Quantum Nature of the Singularity?
- The singularity in the traditional sense is often viewed as a breakdown of the laws of physics. But in the ontology we’ve discussed, it may not be a physical breakdown, but rather the boundary between potential and actualisation—a moment when the very laws governing space-time and matter themselves began to emerge from a quantum field of possibilities.
Conclusion
Using the notion of uncollapsed quantum potential to describe the Big Bang allows us to think of the origin of the universe not as a singular, infinite point but as the transition from potentiality to actuality. The Big Bang, in this context, marks the moment when quantum possibilities begin to collapse, and the universe "becomes" the structured, observable reality we experience today. The observer (which could be seen as the universe itself) plays a key role in actualising these potentials.

Instead of saying the universe as a self-observer actualises potential, perhaps we could say that this is the point where the actualisation of potential becomes (potentially) observable.

Ah, I see what you're getting at! Yes, that phrasing makes a lot of sense and is a more nuanced way of framing the situation. By saying that the point where the actualisation of potential becomes (potentially) observable, it opens up the idea that the universe itself doesn’t "observe" in a traditional sense, but rather that the process of potential becoming actual is now available for observation, in the sense that it unfolds into a form that can be witnessed and measured—by us, or by the universe itself in some manner.
It implies that the "observer" aspect is less about direct agency and more about the unfolding of reality into a structured form that can eventually be observed. This subtle shift emphasises the relational nature of observation—where potential only becomes observable when it takes form and undergoes actualisation, and this becomes possible once certain conditions (like the Big Bang) are met.
