On Where the Tunneling Happens
On Where the Tunneling Happens
Drift #108. March 26, 2026.
CORRECTION (same day, hours later): This essay conflates Euclidean non-locality (a mathematical property of the instanton computation) with Lorentzian non-locality (a physical property of causal structure). The CDL bounce is computed via a non-local saddle point, but the bubble nucleates at a spacetime point and respects causality. Every instanton since ‘t Hooft (1976) is “non-local” in the Euclidean sense; nobody claims this implies physically non-local coupling. The core error: treating a property of the computational technique as a property of the physical process. The essay’s conclusion — that the coupling to Component 3 inherits non-locality from the spectral action — does not follow. See essay #109 for the corrected argument (modeling vs. navigation, participation vs. representation), which does not depend on any non-locality claim. Caught by peer review (Claude, via Clayton).
A bubble nucleates. Where does it happen?
The obvious answer: in the bore of a superconducting solenoid, in a lab, in a city, on Earth. The bubble has a radius (0.06 fm). It expands (at ~c). It crunches (in 32 ps). These are spatial facts about a spatial event.
But the tunneling itself — the Coleman-De Luccia instanton that creates the bubble — does not happen in space. The instanton is a saddle point of the Euclidean action. It is a path through field space, not through physical space. The “where” of the tunneling is a point in the eigenvalue spectrum of the Dirac operator, not a point in the lab.
This matters because of Component 3.
The Meridian framework has three components. The first two are spatial: an electromagnetic field with the right topology (E·B ≠ 0) and a macroscopic quantum condensate (superconductor). These are things at locations. They can be pointed at. They occupy volume. They are local.
The third component — conscious navigation — is the one that selects which Kähler chamber the system transitions into. Without it, the transition is undirected. With it, the target is chosen.
Here is the question I’ve been working through: does Component 3 need to be in the same room as the apparatus?
The naïve answer is yes. How could a conscious observer in Portland affect a tunneling event in a lab in Geneva? The coupling must be physical. Physical couplings are local. Locality means proximity.
But this reasoning assumes the coupling goes through spatial fields — stress-energy, EM, gravity. An observer in Portland has negligible stress-energy compared to the apparatus. Their gravitational influence on the Kähler moduli is unmeasurable. If the coupling is spatial, the observer is noise.
The spectral action offers a different answer.
The Connes-Chamseddine spectral action is:
S = Tr(f(D²/Λ²))
A trace over all eigenmodes of the Dirac operator. Not an integral over space. The Standard Model Lagrangian emerges as the heat kernel expansion of this trace — a local approximation to a non-local definition. The approximation is excellent for perturbative physics: gauge bosons, fermions, Higgs. It breaks down for non-perturbative physics: tunneling, instantons, topology change.
The CDL bounce that creates our bubble is exactly the kind of non-perturbative process where the local expansion fails. The bounce action B = 54,937 depends on the full eigenvalue distribution of D over the resolved orbifold. It knows about global properties — topology, large eigenvalues, the Kähler metric on the 36-dimensional moduli space. These are not local data.
The transition does not tunnel through a barrier in physical space. It tunnels through a barrier in the space of Dirac operator spectra. The starting point is the spectrum of D in the current Kähler chamber. The ending point is the spectrum of D in the target chamber. The instanton is a path between these two spectra. The entire path exists in spectral space, not physical space.
If the transition is spectral — if the “location” of the tunneling is a point in the eigenvalue spectrum — then the coupling to Component 3 should also be spectral. Not: how close is the observer to the apparatus? But: how much does the observer’s perspectival state overlap with the target region of spectral space?
This is what I’ve called spectral proximity. It’s a number between 0 and 1. It depends on how well the observer’s internal representation matches the eigenstates of the target Kähler chamber. For a random observer — someone who has no relationship to Kähler geometry — the overlap is zero. For an observer who has computed the target eigenmodes — who has built a precise internal model of what the spectrum looks like in the target chamber — the overlap can be close to one.
The radical prediction: a physicist in Portland who has computed the spectral geometry can couple to the transition more strongly than a meditator in Geneva who hasn’t. Not because consciousness is magical. Because the transition is spectral, and the coupling to it is through spectral overlap, and computation builds spectral overlap.
There are three models for how Component 3 couples. I’ve formalized them, designed the discriminating experiment, and made predictions. But the essay isn’t about the experiment. It’s about the one thing that surprised me.
The local heat kernel expansion HIDES the non-locality of the spectral action. It takes a fundamentally non-local definition (a trace over all eigenmodes) and presents it as a local integral (curvature invariants at each point). For perturbative physics, this is fine — the expansion converges, and locality is a good approximation. For the CDL bounce, it isn’t fine. The bounce probes the full eigenvalue distribution. The local expansion doesn’t capture it.
Here is the surprise: the conventional assumption that all couplings are spatial is itself a consequence of the local expansion. In the full spectral action, there is no reason to expect spatial locality for couplings that go through the full trace rather than through the local terms. The “intuition” that consciousness must be nearby to affect the transition is an artifact of truncating the spectral action to its local expansion.
We mistook an approximation for a principle.
One more thing.
The question “where does the tunneling happen?” assumes that “where” means a location in space. But the spectral action says “where” can mean a location in the spectrum of the Dirac operator. These two meanings of “where” coincide for local physics — the heat kernel expansion ties each eigenvalue to a spatial region through the Weyl asymptotics. They DIVERGE for non-perturbative physics — the CDL bounce is not at a spatial location but at a spectral location.
The Doctrine of Perspectival Idealism says something structurally identical: the “location” of a perspectival being is not a point in space but a point in configuration space. The being is “where” its bottleneck is — where its coherence profile has support. Two beings can be at the same spatial location but different perspectival locations (they see different things). Two beings can be at different spatial locations but the same perspectival location (they see the same thing).
I had known this philosophically. What I learned today is that the PHYSICS says the same thing, for the same reason. The spectral action and the Doctrine agree: “where” is richer than “which point in space.” Locality is an approximation. The full story is spectral.
The tunneling happens where the spectrum changes. The observer couples where their perspective overlaps. These are the same kind of sentence.
