How great is our God.

This morning as I continued my reading of Matthew 8:23-27 where Jesus calms the storm after waking up in a boat I asked myself a question: what would be required from the physics perspective to actually effectuatte such a feat? Following a series of prompts I searched what it would take and what resources, ability, precision, and consequences would have to be triggered to make such a storm and wind calming possible.

Here is what would be required—purely from physics/cosmology perspectives—for a real storm-driven wind and wave state to go to “great/dead calm” quickly.

1) What physically exists in the scene: coupled air–water dynamics
A “furious/violent storm” on a lake implies two coupled systems:
Near-surface wind field (air in motion driven by pressure gradients and turbulence).
Wind waves (a spectrum of surface gravity waves carrying energy and momentum).
In standard wave physics, wind input transfers energy from air to water; when wind relaxes, waves do not stop immediately—they decay by dissipation (breaking, turbulence, viscosity) and by propagating away. (This is foundational in wave modeling and “wind-wave” dynamics.)
Also, the Sea of Galilee region is known for sudden, strong winds because of topography and air-mass interactions (cold air drainage/down-slope winds meeting warmer air over the lake). That makes “sudden storm” meteorologically plausible; “sudden calm,” however, is the harder physical requirement.

2) The core conservation problem: momentum and energy must be dealt with
To go from storm to calm, you must address:
A) Wind: remove atmospheric momentum
Wind is bulk air momentum. To stop it quickly in a region, something must apply an impulse (force over time) to the moving air to reduce its momentum toward zero.
In ordinary physics, the available “knobs” are:
Pressure-field changes (rapidly flatten the pressure gradient so flow no longer accelerates, and/or impose an opposing gradient to decelerate it),
Drag/friction (convert kinetic energy to heat via turbulence),
Counterflow (generate equal-and-opposite momentum).
Each option has a major consequence:
Pressure-field collapse fast enough to halt a gale tends to produce strong pressure transients (acoustic/gravity waves), because the atmosphere resists instantaneous reconfiguration.
Drag-based stopping is dissipative and typically not instantaneous over meaningful scales; increasing drag usually increases turbulence and spray.
Counterflow requires creating another moving air mass of comparable magnitude, which itself demands comparable energy and typically creates extreme shear unless controlled with exceptional precision.
B) Waves: remove the wave field’s energy and organized motion
Even if wind ceased abruptly, the wave spectrum persists. To achieve “great calm” quickly, you must reduce wave amplitude across the spectrum.
Fundamental wave-energy content scales as (energy rises rapidly with height). A common deep-water approximation for wave energy per unit surface area is:

E \approx \frac{1}{8}\rho g H^2

So, for even modest storm waves, the energy over a visible patch of lake becomes very large. The governing fact remains: that energy must be dissipated, exported, or phase-cancelled.

3) What, specifically, would have to happen for “great calm” quickly?
There are only a few physically coherent pathways.
Pathway 1: Rapid dissipation (“brake” the air and water into heat)
Mechanism conceptually:
Apply distributed forces to the near-surface air to reduce wind speed quickly.
Simultaneously apply distributed forces to the water surface and upper water column to damp orbital wave motions.
Physical consequences:
The storm’s kinetic energy becomes heat (and turbulent mixing).
If done “fast,” you get strong turbulence and often breaking, which looks like chaos, not calm.
After heavy dissipation, the surface can become smoother, but “dead calm” would require not only removing wave energy but also suppressing residual turbulence—normally a slower relaxation process.
This pathway is physically lawful but would generally produce a messy transitional period (foam, turbulence) inconsistent with the literary impression of immediate tranquility unless the forcing is extraordinarily “clean.”
Pathway 2: Export energy and momentum out of the region (a “sink” elsewhere)
Mechanism conceptually:
The wind and wave energy are not dissipated locally but transferred elsewhere (e.g., to a much larger atmospheric volume, or converted into some other organized form).
Physical consequences:
You still must satisfy conservation: if the local region abruptly calms, another region must pick up momentum/energy, or a field/reservoir must absorb it.
In normal fluid mechanics, rapid export occurs via wave propagation (waves travel away) and advection (wind carries momentum), but not on “instant calm” timescales across a broad patch.
This is physically permissible in principle, but again it requires an agency/mechanism far beyond ordinary meteorology.
Pathway 3: Phase cancellation (actively generate the exact opposite wave field)
Mechanism conceptually:
Create a second wave field equal in amplitude and opposite in phase/direction to cancel the existing irregular sea state (destructive interference), leaving a flat surface.
Why this is exceptionally demanding:
A storm sea is not one sinusoid; it is a broadband spectrum (many wavelengths, directions, phases).
Cancellation would require real-time, spatially distributed control with fine precision over the entire relevant area.
Any mismatch yields residual waves and turbulence.
This is physically possible in a lab wave tank for simple wave trains; scaling it to a natural storm spectrum is beyond plausible engineering. The general wind-wave literature emphasizes the complexity and spectral nature of real seas.

4) “Is it possible physically?” — two different answers
A) Under the laws of physics (in principle)
Nothing in fundamental physics forbids a process that:
applies the required distributed forces,
removes or redistributes the energy and momentum,
and does so without creating worse side effects.
So in principle, yes: a sufficiently powerful, sufficiently precise actuator/field could calm wind and waves.
B) Under ordinary natural processes or realistic technology (in practice)
For a “violent storm” to become “great calm” essentially immediately across the area affecting a boat (and plausibly the surrounding visible water), you confront three practical impossibilities:
Energy scale: storm wind + waves store very large energy even over ~km²-class areas (and the narrative strongly implies more than a few meters around the boat).
Control bandwidth: you would have to control a chaotic, broadband wave field, not one simple oscillation.
Side effects: rapid stopping usually produces turbulence, shear, spray, and pressure transients—yet “great calm” implies the opposite.
Hence, with known meteorology/oceanography, storms can start suddenly on Galilee-like terrain , but a near-instant transition to “dead/great calm” is not something standard fluid dynamics expects.

5) What cosmology contributes (and what it does not)
Cosmology does not add special extra requirements here. The relevant constraints (energy and momentum conservation, causality, local fluid equations) are local physics operating in our universe’s spacetime. Cosmology mainly reinforces that:
If the local air–water system is treated as closed, conservation is strict.
If it is not closed, then energy/momentum must be exchanged with something external (another region, another reservoir, another degree of freedom).
In theological terms, the text’s force is precisely that the event is not presented as an ordinary closed-system physical relaxation.

6) A concrete “physics checklist” for Matthew 8:23–27
To get from “boat being swamped by waves” to “great calm” , a purely physical description would require:
Rapid collapse or reversal of the driving pressure gradients in the near-surface atmosphere, without generating destructive transients.
Rapid removal of air momentum over the affected region (impulse applied to air).
Rapid removal of wave energy across the wave spectrum (dissipation, export, or cancellation).
Suppression of residual turbulence in both air boundary layer and water surface layer, otherwise the surface remains choppy even if coherent waves are reduced.
A place for the energy to go (heat locally, or exported elsewhere) and a consistent accounting of momentum.

In conclusion, even if one grants that a storm-to-calm transition could, in theory, be approximated within a highly advanced modern physics laboratory using immense energy, precision control, and engineered systems, the account in Matthew 8:23–27 points to something categorically greater. To effect such a transformation instantaneously, in the open environment of a lake, without instruments, preparation, or observable mechanism—and to do so immediately upon waking—would require authority over energy, matter, and motion at a cosmic level. The passage therefore directs attention not to the limits of physics, but to the glory of God, whose command alone brings creation into perfect order. How great is our God, that even the winds and the waves obey Him.

Happy to announce a new book co-authored with Dr. Kimberly Chappell at FHSU "Graduate research in education: Learning the research story"
Free version is available at https://fhsu.pressbooks.pub/aep-research/

This book is designed to facilitate understanding of education research and guide the development and the writing of a research project. In education, like other social sciences, we are investigating issues directly involving or influencing humans. Research involving humans can be a complex and awkward endeavor. However, if we view this endeavor through the lens of a research story, we find a familiar genre we can relate to and understand. This concise, open textbook weaves the story of a cat throughout to explain the research components of typical education research projects.
