O_2_13 Verified Earth Anomalies

O_2_13 — Isostatic Rebound: Post-Glacial Land Rise and Coastal Change

Glacial isostatic adjustment (GIA, commonly called isostatic rebound or post-glacial rebound) is the ongoing process by which Earth's crust and mantle adjust to the removal of the immense weight of continental ice sheets

O_2_04 Verified Earth Anomalies

O_2_04 — Geological Hotspots and Mantle Plumes

Geological hotspots are locations where anomalously high volcanic activity occurs away from tectonic plate boundaries — the dominant hypothesis explains them as surface expressions of mantle plumes, columns of hot, buoya

ZF_1_03 — Seafloor Spreading, Plate Tectonics and Marine Geology

The discovery that the ocean floor is not ancient and static but young, dynamic, and continuously recycled revolutionized Earth science in the 20th century. Seafloor spreading — proposed by Harry Hess (1962) and confirme

Q_4_10 Verified Cosmology & Physics

Q_4_10 — Fluid Dynamics: Turbulence, Navier-Stokes, and the Millennium Problem

Fluid dynamics is the study of the motion of fluids (liquids and gases) — a branch of physics with applications spanning aeronautics, meteorology, oceanography, astrophysics, cardiovascular medicine, chemical engineering

O_1_07 Earth Anomalies

O_1_07 — Gravity Anomalies, Mascons & Earth's Uneven Field

Earth's gravitational field is not uniform — it varies by approximately ±0.05% from the global average, creating a lumpy "geoid" where the local strength of gravity depends on the density and distribution of mass beneath

O_2_20 Dubious Earth Anomalies

O_2_20 — Hollow Earth Theory

The Hollow Earth theory proposes that the planet's interior is partially or entirely hollow, potentially containing habitable spaces, inner suns, atmospheres, or even advanced civilizations. This idea has ancient roots i

O_2_09 — The Mohorovičić Discontinuity and Earth's Internal Structure

The Mohorovičić Discontinuity (the "Moho") — the boundary between Earth's crust and upper mantle — is one of the most fundamental structural features of our planet and a cornerstone of solid-Earth geophysics. It was disc

O_2_03 Earth Anomalies

O_2_03 — Plate Tectonics, Continental Drift, and Deep Earth

Plate tectonics — the theory that Earth's outer shell (lithosphere) is divided into rigid plates that move, collide, and separate atop a convecting asthenosphere — is one of the great unifying theories of modern science.

O_2_01 — Volcanism, Supervolcanoes, and Geological Catastrophism

Volcanic eruptions are among the most powerful forces on Earth, capable of altering global climate, triggering mass extinctions, collapsing civilizations, and imprinting themselves on human mythology for millennia. The T

ZA_5_10 — Superfluidity: Quantum Mechanics at the Macroscopic Scale

Superfluidity — the macroscopic quantum phenomenon in which a fluid flows with zero viscosity (no resistance to flow) and exhibits extraordinary properties including frictionless flow through narrow channels, the ability
