The Inquiry
From question to expedition, in five stages.
This is not a theory. It's an investigation. And investigations end with fieldwork.
ALBA follows a single thread: if an advanced non-industrial civilisation existed before the Younger Dryas, what would the evidence look like, and where would it point? Each stage builds on the previous one. Each conclusion is testable, falsifiable, and published.
Stage 01
The Question
Could a clean-energy civilisation have existed 13,000 years ago?
In 2018, two astrophysicists at NASA published a provocation in the International Journal of Astrobiology. Gavin Schmidt and Adam Frank asked: if a civilisation had existed millions of years before us, would we detect it? Their answer: probably not. They called it The Silurian Hypothesis.
ALBA's key modification: we don't need millions of years. We need 13,000. Just before the Younger Dryas. At that timescale, the traces aren't erased by geology. They're erased by water: 120 metres of sea-level rise since the Last Glacial Maximum.
If an advanced maritime civilisation existed, its coastal cities are now underwater. Invisible to land-based archaeology.
Standard linear development. Humanity progressed gradually from hunter-gatherers to agriculture to industry. Currently 65-80% prior probability.
Advanced non-industrial civilisation, pre-Younger Dryas (~12,800 BP). Clean energy, no industrial traces. Currently 20-35% prior probability.
"Silurian" civilisation, >4 million years ago. Original Frank & Schmidt scope. Currently 0.5-2% prior probability.
The Bayesian approach: we don't "believe" in H₃. We calculate its probability as evidence accumulates. Each piece of evidence moves the cursor. The cursor moves with the data, not with opinion.
The question is posed. But for it to hold, we need a mechanism. How can an entire civilisation disappear without a trace? The answer is in the ice, and in fire from the sky.
Stage 02
The Fingerprint
Identifying what to look for.
12,800 years ago, a cosmic impact triggered the Younger Dryas: 1,300 years of brutal cooling, mega-tsunamis, continental fires. The evidence is now confirmed across five continents: shocked quartz, platinum anomalies, microspherules, nanodiamonds (Sweatman, 2021).
If a civilisation was destroyed by this event, what traces would remain above the waterline? Not cities. Fragments of transmitted knowledge, embedded in the most enduring structures built by survivors.
Göbekli Tepe (9,600 BCE) — 50-tonne monoliths by hunter-gatherers. Date matches Plato's timeline exactly. Haklay & Gopher (2020) call it a "quantum leap".
Antikythera Mechanism (~100 BCE) — 1,400-year gap before comparable technology. Freeth et al. (2021, Scientific Reports).
Giza, Baalbek, Kailasa, Delhi Pillar — Precision, scale, and material science that each require separate ad hoc explanations under H₀.
The common technological signature: Φ-ratio geometry, proximity to geological faults, piezoelectric and electromagnetic materials, mercury deposits, acoustic resonance properties. Under H₀, each anomaly is a coincidence. Under H₃, one model explains them all: fragmentary transmission from a common source.
The fingerprint is defined. If these sites share a common technological source, that source had a location. Can the geometry of the network point to it?
Stage 03
The Search
Following the geometry to a single point on Earth.
If the anomalous sites are connected by Φ-geometric relationships, and if they share a Grand Circle alignment, their network has a mathematical centre. ALBA computed this centre.
The Grand Circle connecting major ancient sites achieves an alignment of R² = 0.9998. The geometric barycentre, computed from Φ-ratio relationships between sites, falls at a single point:
Statistical validation: the probability that random site placement would produce this degree of convergence is less than one in a million.
Not a guess. A calculation. Published, reproducible, and open to scrutiny.
The geometry points to a location. But a mathematical prediction is not evidence. Can independent datasets confirm what the geometry suggests?
Stage 04
The Validation
Testing GEBCO Hill against every available dataset.
A prediction is only as good as its independent validation. ALBA tested GEBCO Hill against datasets that had no role in its identification: Plato's original Greek texts, bathymetric surveys, palaeo-hydrology, local geology, flood mythology, population genetics, archaeoastronomy.
The result: 35 annotations in Plato's text match GEBCO Hill. Not vague metaphors. Specific, measurable, falsifiable correspondences verified against GEBCO bathymetry, ETOPO elevation, GMRT high-resolution profiles, and Greek philological analysis.

Catastrophe
35 annotations. Zero contradictions. Every testable criterion either matches GEBCO Hill or requires fieldwork to verify. No other candidate site on Earth satisfies even half of these.
Independent Confirmations (non-textual)
Flood myths correlate with post-glacial bathymetry — Nunn methodology
Sama-Bajau sea nomads: genetic adaptation to diving — consistent with maritime diaspora
Nazca lines geometric convergence on GEBCO Hill
Archaeoastronomical alignments to Betelgeuse — consistent with pre-YD dating
The self-refutation: Monte Carlo audit with 50,000 random control corpora identified overclaimed Bayes Factors. ALBA retracted its own numbers: 200–500 → 10–25. GEBCO Hill survived our own attempt to destroy it.
The evidence is in. Twelve out of fifteen criteria are satisfied. The three remaining require physical investigation. There is only one way to resolve this.
Stage 05
The Synthesis
What survives the audit?
Ten independent evidence lines across eight disciplines. Each one tested, categorised, and assigned a Bayes Factor. Some were retracted when they failed Monte Carlo audit. What remains is the cumulative signal.
Zenodo §16–18 — Synthesis, Scorecard, LimitationsProbability Evolution (cumulative Bayesian updates)
[F] Formal — Derived from explicit statistical models with defined likelihood functions, testable against null distributions.
[S] Semi-formal — Combines empirical data from peer-reviewed sources with structured likelihood estimation. Observations are factual; conditional probabilities involve informed judgment.
[H] Heuristic — Structured expert judgment where both likelihoods involve substantial subjective estimation. Rigorous reasoning, not statistical calculation.
The cursor started at 20%. It moved to 96%. Not because we wanted it to, but because each independent dataset pushed it in the same direction.
Criteria Scorecard
Testing H₃ and GEBCO Hill against explicit criteria.
Each criterion stated in advance, tested independently, scored pass/fail. Three remain unresolved: all three require fieldwork.

Falsification Criteria
How to prove us wrong.
Science that cannot be falsified is not science. Here is what would refute H₃ and the GEBCO Hill identification.
Test 01
High-resolution sonar shows only natural geology?
Multi-beam bathymetry at <5m resolution reveals no geometric patterns, no concentric structure, no engineered features.
→ GEBCO Hill identification refutedTest 02
Sediment core contains no anthropic markers?
Core sampling at GEBCO Hill summit shows undisturbed natural sediment. No charcoal, no worked materials, no anomalous chemistry.
→ Habitation hypothesis refutedTest 03
Diving reveals natural reef, no structures?
Direct visual inspection of GEBCO Hill summit (−19m) shows coral reef and natural rock formations. No worked stone, no archaeological remains.
→ H₃ at this location refutedWe state in advance what would prove us wrong. If the expedition returns negative results, we publish them with the same rigour.
Stage 06
The Expedition
The evidence is in. Now we go.
GEBCO Hill sits at -19 metres. Standard diving depth. The site is identified, the methodology is published, the coordinates are public. A 14-day mission from Brooke's Point, Palawan, using multi-beam sonar, ROV, and targeted diving.
GEBCO Hill — summit at -19m — accessible by standard scuba diving
Deep Zone — depth -83m — requires ROV for deep survey
Three phases: sonar mapping of the complete site, ROV survey of the deeper zone, targeted diving on GEBCO Hill. Every result published, positive or negative.
What if we find nothing? We publish the negative result. That's science. Even a null result advances knowledge and closes a hypothesis with integrity.
This investigation began with a question.
It ends with coordinates, a methodology,
and a site at diving depth.
The only step left is fieldwork.
