| | + | The breaking of the crust, and the out-rushing of the subcrustal ocean, produced earthquakes the like of which had not occurred before and will never occur again. These earthquakes, acting on [[quartz]] distributed liberally but unevenly throughout the earth's crust, created electromotive potentials high enough to ionize [[atom]]ic nuclei completely and to break down the natural resistance of these nuclei to fuse. Heavy-elemental nuclides fused to form super-heavy elements. These then decomposed, by a combination of fission and cluster decay, to produce [[uranium]], [[thorium]], and [[radiocarbon]]. Uranium and thorium were subject to [[acclerated decay]] and produced the rest of the trans-lead elements we know today. (The heaviest isotope of uranium might also have decayed, in the wild, through a two-step beta-decay pathway to produce [[neptunium]] and [[plutonium]].) |

| | + | This process released a "tsunami" of [[neutron]]s that flowed in all directions. The subcrustal ocean absorbed most of these neutrons. The subcrustal waters that escaped, persist as cometary ices that are known to have twice (or more!) of the concentration of [[deuterium]] one finds in the oceans of earth. Other crustal elements absorbed the remaining neutrons, to form the heavy (and in some cases, radioactive) isotopes of lead and lighter elements. |

| | + | Radiocarbon presents a special case. The above process more than doubled the amount of radiocarbon in the atmosphere. In addition, the Great Flood itself sequestered significant portions of the earth's carbon stores. (Today, the "carbon age" of most fossil fuel deposits turns out to be "indefinite" or "infinite.") Post-Flood plants took up this radiocarbon. Any such plants, and any animals that ate their seeds, fruits, and vegetables, also took up this radiocarbon. They also took up heavy isotopes of key elements found in [[protein]]s, [[vitamin]]s, and other nutrients. With two untoward results: |
| | + | |
| | + | #Any protein or other large molecule could degenerate any time from the sudden decay of an atom of radiocarbon to [[nitrogen]]. |
| | + | #Proteins might not "conform" properly because some of the atoms in their secondary structures (alpha-helices and beta-pleated sheets) were too heavy. |
| | + | |
| | + | Result: the lifespan of humankind fell ninety percent in eleven generations, as per the Annals of [[Terach]]. |

| | + | == Date of the Great Flood == |
| | + | Two of the comets, Halley and Swift-Tuttle, have orbits that usually carry them far away from any interfering bodies. Statistical backtracking of them establishes that both would have been most likely to be at perihelion at the same time, in the year 3290 BC or as much as one hundred years earlier or later. This has profound implications for [[Biblical chronology]]. |
