E_4_27 — Chicxulub Impact and the K-Pg Mass Extinction
The Chicxulub impact was a catastrophic asteroid strike that occurred approximately 66.043 ± 0.011 million years ago at what is now the Yucatan Peninsula, Mexico, marking the boundary between the Cretaceous and Paleogene
E_4_14 — Stratigraphic Methods and Geological Timekeeping
Stratigraphy — the study of rock layers (strata) and their sequential relationships — is the foundational framework for understanding geological time and establishing the chronology of Earth's 4.54-billion-year history.
E_1_08 — Ancient Supernovae and Their Cultural Impact
Supernovae — the explosive deaths of massive stars — are among the most energetic events in the universe, capable of briefly outshining entire galaxies. When they occur within our galaxy at distances of a few thousand li

This document examines Meteor and Asteroid Impacts on Earth, a topic within the Cataclysms and Chronology research area. Notable findings include: The Finnish Kalevala describes a "fire-child" stolen from heaven that bur
E_1_15 — Uranium-Thorium Dating: Methodology and Applications in Deep Time
Uranium-thorium (U-Th) dating, also called uranium-series disequilibrium dating, is a radiometric technique that measures the decay of ²³⁴U to ²³⁰Th (half-life: ~245,620 years) in materials such as speleothems (cave form
E_1_10 — Impact Crater Morphology and Effects
Hypervelocity impact cratering — the formation of craters by the collision of asteroids, comets, and meteoroids with planetary surfaces at speeds of 11–72 km/s — is one of the most fundamental geological processes in the
E_1_07 — Tunguska Event and Modern Impact Evidence
On June 30, 1908, an atmospheric explosion over the Podkamennaya Tunguska River in central Siberia released energy equivalent to approximately 12 megatons of TNT (roughly 1,000 times the Hiroshima bomb), flattening 2,150
E_1_09 — Solar Storms and Miyake Events
The Sun periodically releases enormous bursts of energy — coronal mass ejections (CMEs) and solar proton events (SPEs) — that interact with Earth's magnetosphere and can have devastating consequences for technology-depen
E_1_17 — Toba Supereruption: Genetic Bottleneck and Climate Catastrophe
The Toba supereruption — occurring approximately 74,000 years ago (74 ka) on the island of Sumatra, Indonesia — was the largest volcanic eruption of the last 2 million years and one of the most catastrophic events in hum
E_1_06 — Chicxulub Impact and the K-Pg Boundary
Approximately 66 million years ago, at the boundary between the Cretaceous and Paleogene periods (K-Pg boundary, formerly K-T boundary), a ~10 km diameter asteroid struck what is now the Yucatán Peninsula of Mexico, crea
E_5_05 — Late Devonian Mass Extinction: Kellwasser and Hangenberg Events
The Late Devonian mass extinction (~372–359 Ma) was not a single catastrophe but a series of extinction pulses spanning approximately 25 million years, making it unique among the "Big Five" mass extinctions. The two most
ZG_2_08 — Etymology and Historical Word Origins
Etymology is the study of the origin, history, and changing meanings of words — tracing the life of a word from its earliest attested form (or its reconstructed proto-form) through the centuries of sound change, semantic
ZG_2_17 — Ethiopic Ge'ez Script and Literary Tradition
Ge'ez (ግዕዝ) is the classical Semitic language and writing system of the Aksumite Empire (c. 100–940 CE) and the Ethiopian Orthodox Tewahedo Church, and the ancestor of the modern Ethiopic script (fidäl) used today for Am
