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_08 — Justinianic Plague & Late Antique Pandemics

The Justinianic Plague (541–750 CE) was the first historically documented pandemic of bubonic plague caused by Yersinia pestis, striking the Byzantine Empire at the height of Emperor Justinian I's reconquest campaigns. A

Q_1_14 — Vacuum Energy and the Cosmological Constant Problem

The cosmological constant problem is widely regarded as the most severe fine-tuning problem in all of physics. Quantum field theory predicts that the vacuum of spacetime is not empty but seethes with zero-point fluctuati

Q_2_13 — Interstellar Medium, Dust, and Nebulae

The space between stars is far from empty — the interstellar medium (ISM) is a complex, dynamic ecosystem of gas, dust, magnetic fields, and cosmic rays that pervades galaxies and plays a central role in stellar birth, d

O_3_01 — Biodiversity, Ecosystem Intelligence, and the Superorganism

Earth harbors an estimated 8.7 million eukaryotic species (Mora et al. 2011), of which only ~1.5-1.8 million have been formally described — meaning roughly 80% of species remain unknown to science. When prokaryotes (bact

T_1_09 — Psychology of Learning and Conditioning

Learning — relatively permanent changes in behavior or behavioral potential resulting from experience — is the foundational process of behavioral adaptation. Three paradigms dominate: classical conditioning (Pavlov, 1927

L_1_07 — Genetic Bottlenecks, Founder Effects, and Toba

Genetic bottlenecks — dramatic reductions in population size that slash genetic diversity — and founder effects — the reduced variation carried by small colonizing groups — have profoundly shaped the genomes of species f

H_3_04 — Destruction of Aboriginal Australian Knowledge Systems

The destruction of Aboriginal Australian knowledge systems represents the disruption of the longest continuous cultural tradition on Earth — spanning at least 65,000 years. From the arrival of the First Fleet in 1788, co

This document examines Deep Time and Cognitive Limits, a topic within the Philosophy Meaning research area. Key areas of investigation include Origins of the Concept, The Scale Problem, The "Human Line" Problem. The anal

ZE_3_01 — Environmental Ethics and Deep Ecology

Environmental ethics examines the moral relationship between humans and the natural environment — Do non-human entities have intrinsic value? Do we have moral obligations to ecosystems, species, and future generations? T

R_5_02 — Megafauna Extinction: Quaternary Losses and the Overkill Debate

Between ~50,000 and 10,000 years ago, Earth lost the majority of its large-bodied animals (megafauna >44 kg) — woolly mammoths, ground sloths, saber-toothed cats, giant wombats, moa, and dozens of other spectacular speci
