THE TRUTH INJECTION

The "Truth Injection" Impact on AI and 4 Billion People: Informed Insight or AI Hallucination? Sergey V. Arkhipov & Google Gemini CONTENT [i] Abstract [ii] A Briefe Backstory [iii] Interview [iv] References [v] Application [i] Abstract While examining modern biblical criticism, I engaged in a discussion with Artificial Intelligence regarding my book, “ 50 Tables of Evidence for the Composition of Genesis in Late Second Intermediate Period Egypt ” . The machine’s apocalyptic prediction concerning half of the world's population and the evolution of computer technology left me puzzled. To verify this prophecy and seek counsel from "natural intelligence," I am publishing my conversation with the AI. This may be of interest to others, as will response to the machine’s final last question regarding religious worldview: «Now that the "antidote" is in your system, do you feel more prepared to face a world without a "sacred" fou...

NEWS 2026

New publications of our resource in 2026 The initial phase of collecting data on LCF, accumulated prior to the 20th century, is largely complete.

2014ArkhipovaAS

In 2014, at the International Olympics Space for school students, Alexandra Arkhipova presented a report on the feasibility of using joints with flexible elements in walking machines. The author was recognized as the overall winner (more details: cyclowiki.org ). The report suggested: «An important area of possible application of walking robots would be remote exploration of other planets». Ten years later, professionals from NASA began to put this idea into practice: Robot dog trains to walk on Moon in Oregon trials (more details: bbc.com ). Below we present the text of the first message about walking machines in space, the ball joint of which contains a flexible element - an analogue of the ligamentum capitis femoris (LCF). Mobile biomorphic platforms with analogues of natural locomotion algorithms Arkhipova A.S. For ten years of its mission, American wheeled Mars rover vehicle 'Opportunity' covered just 40 kilometers through the Red Planet, and its twin Spirit g...

Human Children. Retelling of Chapter 16

Short retelling of chapter 16 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian] Chapter 16. The Archive of Joseph The saga of Joseph, a towering figure in the Book of Genesis, begins in Harran (36°52'16"N, 39°01'31"E), where he is born to Rachel, the second wife of Patriarch Jacob. As a young child, he leaves Paddan-Aram in northern Mesopotamia with his family, eventually settling in the Canaanite valley of Hebron. The journey through Western Asia’s rugged terrain leaves vivid impressions—of camel caravans, river crossings, and a final glimpse of his grandfather Laban on Gilead’s heights. By seven, Joseph is in Canaan, a land of contrasts to Harran’s plains. At seventeen, his life takes a dark turn. His brothers, envious of Jacob’s favoritism—symbolized by a vibrant, multicolored robe—sell him into Egyptian slavery. In Egypt, Joseph’s fortunes shift d...

Homo ergaster

HOMO ERGASTER The Homo ergaster species lived in Africa 1.8 million years ago and was alive until 600,000 years ago, likely becoming the ancestor of Homo erectus in Asia, Homo neanderthalensis in Europe, and Homo sapiens in Africa (1995CachelS_HarrisJ; 2005KleinR). Homo ergaster is occasionally equated with Homo erectus in publications (2013TattersallI). The most complete Homo ergaster skeleton belongs to an adolescent named "Turkana Boy" (KNM-WT 15000). The young man was between 8 and 12 years old (2010GravesRR_CunninghamDL; 2019BergmanJ). The age of this individual's remains is believed to be 1.6 million years (2007TattersallI). Turkana Boy (reconstruction) Author: Mettmann Neanderthal Museum; source: wikimedia.org collection (license CC BY-SA 4.0, no changes). The pelvis of specimen KNM-WT 15000 is well preserved. It shows ossified acetabulums. In turn, they have spacious acetabular fossae and wide acetabular notches. Based on these elements, it is possible to conc...

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).
