This volume develops a quantitative, data-constrained reconstruction of Earth's transition from the pre-Flood world, through the year of the Genesis Flood, to the post-Flood environment. Rather than treating Flood geology as a set of isolated hypotheses, it integrates geodynamics, isotope geochemistry, paleomagnetism, radiocarbon systematics, climate reconstruction, and chronology into a single physical framework.
A central methodological principle is explicit parameter accounting: every model parameter is classified as fixed by chronology and physics, physically derived, or fitted against independent data, so that ad hoc assumptions are minimized and falsifiability is maximized.
The reconstruction is anchored to a Masoretic chronology with a Flood date of 2518 BC. The pre-Flood Earth is modeled as a faster-rotating world with an upright axis, a stronger geomagnetic field, and a depleted, non-equilibrium radiocarbon atmosphere. The Flood year itself is treated as an episode of catastrophic geodynamic instability - runaway subduction, collapse of the geomagnetic field through rapid reversals, large-scale mantle reorganization, tidal braking of Earth's rotation, and the acquisition of the modern axial tilt through a Cassini-state transition.
At the center of the model stands a Flood-era neutron-irradiation event, associated with the Vela Jr. supernova remnant, argued to have written much of the isotopic record by transmutation - essentially heat-free - alongside a bounded component of event-initiated decay. Helium retention in zircons, noble-gas inventories, atmospheric argon, cosmogenic Fe and ¹Be, and the radiocarbon system are examined within this one framework. The post-Flood world is modeled as a coupled relaxation of magnetic field, atmosphere, and climate, culminating in a brief Ice Age recorded coherently across a dozen independent ice-core proxies.
Throughout, agreements, unresolved discrepancies, and open uncertainties - including the disposal of mechanical heat - are stated explicitly. Flood Physics is offered not as a completed theory but as a testable research program, with specific predictions and open problems set out to invite further quantitative work on the physical history of the Earth within a young-Earth framework.
