Publications & Open Data
Open science, from hypothesis to seafloor.
Preprint, scripts, datasets. This is how the investigation works.

Reading the Inca Spreadsheet: How Khipu Knots Encode a Syllabic Data Language
Julien Sivan
March 2026 · CC-BY 4.0Brute-force derivation of a 13-symbol syllabary from 619 Andean khipus. The search space of 46,512 valid mappings was exhaustively tested on a calibration khipu, and the resulting syllabary independently replicated on a separate khipu at p = 0.004. Coverage climbed from 44% to ~97% in traceable steps. Twenty proposed readings across eight document types, including tribute registers, cadastral surveys, judicial proceedings, and an astronomical observation catalog.
Other Publications
A Bayesian Search for a Pre-Younger Dryas Non-Industrial Civilisation
Julien Sivan
Ten independent evidence lines across eight disciplines converge on a single location in the Sulu Sea. The paper includes its own Monte Carlo self-refutation and formal retraction of initial claims that did not survive audit. 59 pages, 18 chapters.
Barabar Caves and Other Unexplained Ancient Constructions
Julien Sivan
Finite element simulation of acoustic erosion in granite. One model, one free parameter, eight sites across four continents. Errors under 3%. The geometry emerges from the physics, not from planning.

The strength of the argument lies not in any individual dataset, but in the coherence of their intersection.
Everything is open. Run the scripts. Check the data. Challenge the conclusions.
Science that hides its data is not science. ALBA hides nothing.
