This hypothesis explores the idea that the strong nuclear force may resist disintegration even in the ultimate cosmic expansion phase known as the Big Rip.
If this resistance leads to particle creation when the universe's expansion energy exceeds the confinement energy, it could trigger a feedback process — effectively resetting the universe and initiating a new cosmological cycle.
Let:
- ρ_vac — vacuum energy density driving expansion
- ρ_conf — confinement-related energy density of the strong force
- H — Hubble parameter
We propose a simple feedback equation:
dH/dt = α * (ρ_vac - ρ_conf(t))
ρ_conf(t) = ρ₀ * exp(β * H * t)
Particle creation occurs when:
ρ_vac ≈ ρ_conf
causing a local reduction in H (expansion rate). This may balance the expansion and trigger an effective "reheating" phase — analogous to the early universe.
If this toy model holds, then at the final stage of cosmic acceleration:
- Strong force confinement still resists expansion.
- Expansion energy converts into particle creation.
- Recreated matter and energy slow expansion locally.
- A new equilibrium forms, starting a new cycle — a "Rebirth" rather than a "Rip".
This mechanism could provide a natural, cyclic cosmology driven purely by known interactions.
To express this feedback explicitly:
dH/dt = α * (ρ_vac - ρ₀ * e^(β * H * t))
A dynamic equilibrium (dH/dt = 0) occurs when:
ρ_vac = ρ₀ * e^(β * H * t)
At this point, cosmic acceleration halts and local matter creation becomes dominant.
Is it physically possible for the Strong Force to resist the Big Rip until the very end? We performed an order-of-magnitude estimation to check if the energy scales match.
We calculated the expansion velocity at the moment when the "Phantom Energy" force overcomes the QCD confinement force (Strong Force). Interestingly, the calculation shows that the rip occurs when the expansion speed is close to the speed of light (
This suggests that the immense energy used to tear apart the vacuum could be converted into matter creation (hadronization), effectively triggering a new Big Bang.

The included notebook strong_force_rebirth.ipynb simulates this toy model using basic numerical integration.
It visualizes how H(t) evolves over time given parameters α, β, ρ_vac, and ρ₀.
この仮説は、ビッグリップが起こる最終段階でも、強い力（クォークを閉じ込める力）が完全には崩壊せず、
逆に宇宙の膨張エネルギーを吸収して新しい素粒子を生成する可能性を考えたものです。
その結果、宇宙の膨張が一時的に減速し、エネルギーが再び物質化する過程を経て、
実質的に「新しい宇宙の始まり」が生じる — という仮想モデルを提示します。
