The Hydroplate Theory: Key Assumption

Starting assumptions, as explained above, are always required to explain ancient, unrepeatable events. Only one starting assumption underlies the hydroplate theory. All else follows from that assumption and the laws of physics. Theories of past events always have some initial conditions.  Usually they are not mentioned.

Figure 52: Granite and Basalt. Granite, the dominant continental rock, has a grayish-to-pinkish color. Coarse grains of quartz, which have a glassy luster, occupy about 27% of granite’s volume. Basalt, the dominant rock beneath oceans, is a dark, fine-grained rock. The hydroplate theory assumes that before the flood, granite was above the subterranean water and basalt was below the water.

Assumption: Subterranean Water.  About half the water now in the oceans was once in interconnected chambers about 10 miles below the entire earth’s surface. At thousands of locations, the chamber’s sagging ceiling pressed against the chamber’s floor. These extensive, solid contacts will be called pillars. The average thickness of the subterranean water was about 3/4 mile. Above the subterranean water was a granite crust; beneath the water was a layer of basaltic rock. [See Figure 53.]

Europe, Asia, Africa, and the Americas were generally in the positions shown in Figure 51 on page 111, but were joined across what is now the Atlantic Ocean. On the preflood crust were seas, both deep and shallow, and mountains, generally smaller than those of today, but some perhaps 5,000 feet high. 

Three Common Questions

Those not familiar with the behavior of high-pressure fluids sometimes raise three questions.

1. How could rock float on water? The crust did not float on water; water was trapped and sealed under the crust. (Water pressure and pillars supported the crust.) The crust was like a thin slab of rock resting on and covering an entire waterbed. As long as the water mattress does not rupture, the dense slab will rest on top of less-dense water. Unlike a waterbed’s seal, which is only a thin sheet of rubber, the chamber’s seal was compressed rock almost 10 miles thick. Pressures in the crust 5 miles or more below the earth’s surface are so great that the rock can deform like highly compressed, extremely stiff putty. So the slightest tension crack or opening could not open from below.

In summary, as the flood began, SCW jetted up through a globe-encircling rupture in the crust—as from a ruptured pressure cooker. This huge acceleration expanded the spacing between water molecules, allowing flash evaporation, sudden cooling, and even greater expansion, acceleration, and cooling. Therefore, most of the vast thermal, electrical, chemical, and surface energy43 in the subterranean water ended up not as heat at the earth’s surface but as extreme kinetic energy in all the fountains of the great deep. As you will see, these velocities were high enough to launch much material into outer space—the final dumping ground for most of the energy in the SCW.

2. Temperatures increase with depth under the earth’s surface. Subterranean water about 10 miles deep would have been extremely hot. Wouldn’t all life on earth have been scalded if that water flooded the earth?  No. Today’s geothermal heat is a result of the flood. To understand why and to see why life was not scalded, one must first understand tidal pumping and supercritical water (SCW)—a very high-energy, explosive form of water that was first recognized in 1822.37 One should also understand why continents and preflood mountains sank as the subterranean water escaped. [See Endnote 62 on page 211.]

Tidal Pumping. Tides in the subterranean water lifted the massive crust twice daily. At low tides, the crust settled, compressing and heating the pillars, so temperatures in the subterranean chamber steadily rose, generating a fraction of today’s geothermal heat. Some minerals then dissolved in this hot, high-pressure liquid water, especially limestone (CaCO3), salt (NaCl), and quartz (SiO2). In a few chapters, you will see why, after the flood, this dissolved quartz petrified some wood and cemented flood sediments into sedimentary rocks.

SCW.  At a pressure of one atmosphere—about 1.01 bar or 14.7 psi (pounds per square inch)—water boils at a temperature slightly above 212°F (100°C). As pressure increases, the boiling point rises. At a pressure of 3,200 psi (220.6 bars) the boiling temperature is 705°F (374°C). Above this pressure-temperature combination, called the critical point, water is supercritical and cannot boil.

The initial pressure in the 10-mile-deep subterranean chamber was about 62,000 psi (4,270 bars)—far above the critical pressure. After centuries of tidal pumping, the subterranean water exceeded the critical temperature, 705°F. As the temperature continued to increase, the pressure grew, the crust stretched, and the energy from tidal pumping increasingly ionized the water.38

SCW can dissolve much more salt (NaCl) per unit volume than normal water—up to about 840°F (450°C).  At higher temperatures, all salt precipitates out.39 (In a few pages, this fact will help explain how so much salt was concentrated on the earth and how salt domes formed.)

Hot liquids cool primarily by evaporation from their surfaces.40 SCW consists of microscopic liquid droplets dispersed within water vapor. The rate at which most hot objects cool off depends on their total surface area. The smaller a particle, the larger its surface area is relative to its volume, so more of its heat can be quickly transferred to its surroundings. The liquid in SCW has an area-to-volume ratio that is a trillion (1012) times greater than that of water that might have covered the earth’s surface. Consequently, the liquid in SCW cools almost instantly if its pressure drops. This is because the myriad of shimmering liquid droplets, each surrounded by vapor, can simultaneously evaporate. A typical SCW droplet at 300 bars and 716°F (380°C) consists of 5–10 molecules. These droplets break up and reform continuously.41

This explains how the escaping supercritical liquid transferred its energy into supercritical vapor. How did the vapor lose its energy and cool? Rapid expansion. A remarkable characteristic of supercritical fluids is that a small decrease in pressure produces a gigantic change in volume. So, as the SCW flowed toward the base of the rupture, its pressure dropped and the vapor portion expanded and cooled. As it expanded, it pushed on the surrounding fluid (gas and liquid), giving all fluid downstream greater kinetic energy.

Eventually, the horizontally flowing liquid-gas mixture began to flow upward through the rupture. As the fluid rose, its pressure dropped to almost zero in seconds, so the electrical energy of ionization was released. The 10,000-fold expansion was a weeks-long, focused explosion of indescribable magnitude, accelerating the mixture, including rocks and dirt, into the vacuum of space.42

    

3. What Happens as a Fluid Becomes Supercritical?

Key Experiments. The following experiment was first performed in 1822 by Baron Cagniard de la Tour of France.37 A specific amount of liquid was sealed inside a strong glass tube. The meniscus (the boundary between the liquid below and the vapor above) was visible. As the tube was heated, some liquid evaporated and the pressure increased. The liquid’s density decreased slightly, but the vapor’s lower density rapidly increased. The two densities met at a temperature and pressure called the critical point. At that critical point, the meniscus disappeared. Was the substance a liquid, a vapor, or something else? For almost two centuries, no one knew.44

In 2005, the results of sophisticated experiments on supercritical water were published. That work by scientists in Germany, France, Sweden, the Netherlands, and the United States showed that both liquid and vapor were present. The liquid consisted of microscopic droplets dispersed throughout the vapor.41

A Thought Experiment. What follows is conjecture. To my knowledge, no one has described the microscopic behavior of supercritical fluids (SFs) as I will below, but based on the 2005 experiments, the physics now seems clear. Here is what I believe we would see if we could view the meniscus in microscopic detail as the temperature approached the critical point:

The liquid below the meniscus becomes increasingly agitated and resembles a choppy lake on a windy day. The liquid and vapor are nearly in equilibrium, so about as many molecules evaporate from the liquid as enter the liquid from the vapor. At these very high temperatures, vapor molecules strike the liquid surface at a furious rate and “splash” droplets of liquid up into the dense vapor. As the liquid’s density becomes the same as the vapor’s, the droplets float in the vapor! This process continues until all the liquid below the meniscus is dispersed as tiny droplets in the vapor. Consequently, the meniscus disappears. The shimmering droplets, suspended in the vapor, are then bombarded from all directions by vapor molecules acting as bullets. When these “bullets” strike a droplet, they either fragment the droplet, stick to it, or bounce off the droplet. Sometimes droplets collide and merge.45

Would these microscopic droplets float to the top of the vapor? No, but let’s assume they did. It would mean that the vapor was denser than the liquid droplets. Vapor molecules would be closer to each other, on average, than liquid molecules. Therefore, vapor molecules would frequently bond with each other and become liquid droplets. The presence of liquid droplets throughout the supercritical vapor contradicts our assumption that all the liquid had floated to the top of the vapor. With a little thought, it should become clear that liquid droplets continuously form throughout the equally dense vapor; then they quickly fragment, merge, and evaporate.

As temperatures rise, the vapor molecules travel faster and fragment more droplets. This greatly increases the total surface area of all the droplets. The droplets also collide and merge more frequently, so at each new temperature, an equilibrium is quickly established between droplets forming and disappearing.

Energy is expended in fragmenting a droplet, because work must be done in stretching and breaking the bonds between molecules in the liquid phase. Most of the energy expended in fragmenting a droplet becomes surface energy.43 If the pressure drops, surface energy is given up, and the volume expands rapidly and enormously. The faster the pressure drops, the more explosive the expansion.

When the flood began, the pressure in the escaping SCW dropped in seconds from at least 62,000 psi (4,270 bars) to almost zero. The energy released was huge. Because the 46,000-mile-long fountains continued this release for several weeks, one should not think of it as a single explosion. Instead, the jetting water was a powerful, earth-size engine that launched considerable mass from earth.

Great Solubility. Today, SFs (usually water and carbon dioxide) are studied primarily because of their great dissolving power. In 1879, J. B. Hannay and J. Hogarth first demonstrated this. When they rapidly dropped the pressure in a SF, they observed the dissolved material precipitating as “snow.” Why was the solubility of SFs so great, and why did the solute precipitate so rapidly?

Supercritical liquid droplets impacting solids will break up and dissolve more of the solids than relatively stagnant liquid.46 Also, as described above, the liquid droplets quickly form and evaporate. When they evaporate, the dissolved solids precipitate as sediments onto a floor. When new droplets form from merging vapor molecules, they contain no solute and can then dissolve more of the solid they encounter. As the flood began, the escaping subterranean waters swept most of these loose sediments on the chamber floor up to the earth’s surface.

For these reasons, supercritical liquids can dissolve large quantities of certain solids.47 If the pressure in the supercritical liquid suddenly drops, the liquid evaporates explosively and the solid precipitates as “snow.” Three of the more common precipitates from the subterranean water were limestone (CaCO3), salt (NaCl), and quartz (SiO2).

Figure 53: Cross Section of the Preflood Earth. Several aspects of the early earth are shown here. The chamber’s thickness (exaggerated in the figure) varied. Pillarlike formations, connecting the chamber’s floor and roof, partially supported the roof. (Subterranean water, under high pressure, provided most of the support.) Unlike the cylindrical columns we see in buildings, the subterranean pillars were tapered downward. Pages 369–374 explain how, why, and when pillars formed.

Supercritical water in the subterranean chamber dissolved certain minerals in the chamber’s floor and ceiling—making that rock look like a sponge.48 [Supercritical water is explained on pages 114–115.] High-pressure water filled these voids and supported the porous rock. The Moho, then about 3 miles below the chamber floor, marked the bottom of this porous layer. Seismic waves naturally travel more slowly above the Moho.

All 25 major mysteries described earlier, such as major mountain ranges, ice ages, comets, and the Grand Canyon, seem to be consequences of this basic assumption. The chain of events that flows naturally from this starting condition will now be described as an observer might relate those events. The events fall into four phases.
