Just as there has been glaring scientific fraud in things biological for the past century, there has been a similar fraud in things geological. The error, in a word, is uniformitarianism. This outlook assumes and asserts that the earth’s past can be correctly understood purely in terms of present-day processes acting at more or less present-day rates. Just as materialist biologists have erroneously assumed that material processes can give rise to life in all its diversity, materialist geologists have assumed that the present can fully account for the earth’s past. In so doing, they have been forced to ignore and suppress abundant contrary evidence that the planet has suffered major catastrophe on a global scale. Only in the past two decades has the silence concerning global catastrophism in the geological record begun to be broken. Only in the last 10–15 years has the reality of global mass extinction events in the record become widely known outside the paleontology community. Only in about the last 10 years have there been efforts to account for such global extinction in terms of high energy phenomena such as asteroid impacts. But the huge horizontal extent of Paleozoic and Mesozoic sedimentary formations and their internal evidence of high energy transport represents stunning testimony for global catastrophic processes far beyond anything yet considered in the geological literature. Field evidence indicates catastrophic processes were responsible for most, if not all, of this portion of the geological record. The proposition that present-day geological processes are representative of those which produced the Paleozoic and Mesozoic formations is utter folly. What is the alternative to this uniformitarian perspective? It is that a catastrophe, driven by processes in the earth’s interior, progressively but quickly resurfaced the planet. An event of this type has recently been documented as having occurred on the earth’s sister planet Venus.8 This startling conclusion is based on high-resolution mapping performed by the Magellan spacecraft in the early 1990s which revealed the vast majority of craters on Venus today to be in pristine condition and only 2.5 percent embayed by lava, while an episode of intense volcanism prior to the formation of the present craters has erased all earlier ones from the face of the planet. Since this resurfacing, volcanic and tectonic activity has been minimal. There is pervasive evidence for a similar catastrophe on our planet, driven by runaway subduction of the precatastrophe ocean floor into the earth’s interior.9 That such a process is theoretically possible has been at least acknowledged in the geophysics literature for almost 30 years.10 A major consequence of this sort of event is progressive flooding of the continents and rapid mass extinction of all but a few percent of the species of life. The destruction of ecological habitats began with marine environments and progressively enveloped the terrestrial environments as well. Evidence for such intense global catastrophism is apparent throughout the Paleozoic, Mesozoic, and much of the Cenozoic portions of the geological record. Most biologists are aware of the abrupt appearance of most of the animal phyla in the lower Cambrian rocks. But most are unaware that the Precambrian-Cambrian boundary also represents a nearly global stratigraphic unconformity marked by intense catastrophism. In the Grand Canyon, as one example, the Tapeats Sandstone immediately above this boundary contains hydraulically transported boulders tens of feet in diameter.11 That the catastrophe was global in extent is clear from the extreme horizontal extent and continuity of the continental sedimentary deposits. That there was a single large catastrophe and not many smaller ones with long gaps in between is implied by the lack of erosional channels, soil horizons, and dissolution structures at the interfaces between successive strata. The excellent exposures of the Paleozoic record in the Grand Canyon provide superb examples of this vertical continuity with little or no physical evidence of time gaps between strata. Especially significant in this regard are the contacts between the Kaibab and Toroweap Formations, the Coconino and Hermit Formations, the Hermit and Esplanade Formations, and the Supai and Redwall Formations.12 The ubiquitous presence of crossbeds in sandstones, and even limestones, in Paleozoic, Mesozoic, and even Cenozoic rocks is strong testimony for high energy water transport of these sediments. Studies of sandstones exposed in the Grand Canyon reveal crossbeds produced by high velocity water currents that generated sand waves tens of meters in height.13 The crossbedded Coconino sandstone exposed in the Grand Canyon continues across Arizona and New Mexico into Texas, Oklahoma, Colorado, and Kansas. It covers more than 200,000 square miles and has an estimated volume of 10,000 cubic miles. The crossbeds dip to the south and indicate that the sand came from the north. When one looks for a possible source for this sand to the north, none is readily apparent. A very distant source seems to be required. The scale of the water catastrophe implied by such formations boggles the mind. Yet numerical calculation demonstrates that when significant areas of the continental surface are flooded, strong water currents with velocities of tens of meters per second spontaneously arise.14 Such currents are analogous to planetary waves in the atmosphere and are driven by the earth’s rotation. This sort of dramatic global-scale catastrophism documented in the Paleozoic, Mesozoic, and much of the Cenozoic sediments implies a distinctively different interpretation of the associated fossil record. Instead of representing an evolutionary sequence, the record reveals a successive destruction of ecological habitat in a global tectonic and hydrologic catastrophe. This understanding readily explains why Darwinian intermediate types are systematically absent from the geological record—the fossil record documents a brief and intense global destruction of life and not a long evolutionary history! The types of plants and animals preserved as fossils were the forms of life that existed on the earth prior to the catastrophe. The long span of time and the intermediate forms of life that the evolutionist imagines in his mind are simply illusions. And the strong observational evidence for this catastrophe absolutely demands a radically revised timescale relative to that assumed by evolutionists. But how is geological time to be reckoned? With the discovery of radioactivity about a century ago, uniformitarian scientists have assumed they have a reliable and quantitative means for measuring absolute time on scales of billions of years. This is because a number of unstable isotopes exist with half-lives in the billions of year range. Confidence in these methods has been very high for several reasons. The nuclear energy levels involved in radioactive decay are so much greater than the electronic energy levels associated with ordinary temperature, pressure, and chemistry that variations in the latter can have negligible effects on the former. Furthermore, it has been assumed that the laws of nature are time invariant and that the decay rates we measure today have been constant since the beginning of the cosmos—a view, of course, dictated by materialist and uniformitarian belief. The confidence in radiometric methods among materialist scientists has been so absolute that all other methods for estimating the age of geological materials and geological events have been relegated to an inferior status and deemed unreliable when they disagree with radiometric techniques. Most people, therefore, including most scientists, are not aware of the systematic and glaring conflict between radiometric methods and nonradiometric methods for dating or constraining the age of geological events. Yet this conflict is so stark and so consistent that there is more than sufficient reason, in my opinion, to aggressively challenge the validity of radiometric methods. One clear example of this conflict concerns the retention of helium produced by nuclear decay of uranium in small zircon crystals commonly found in granite. Uranium tends to selectively concentrate in zircons in a solidifying magma because the large spaces in the zircon crystal lattice more readily accommodate the large uranium ions. Uranium is unstable and eventually transforms, through a chain of nuclear decay steps, into lead. In the process, eight atoms of helium are produced for every initial atom of U-238. But helium is a very small atom and is also a noble gas with little tendency to react chemically with other species. Helium, therefore, tends to migrate readily through a crystal lattice. The conflict for radiometric methods is that zircons in Precambrian granite display huge helium concentrations.15 When the amounts of uranium, lead, and helium are determined experimentally, one finds amounts of lead and uranium consistent with more than a billion years of nuclear decay at presently measured rates. Amazingly, most of the radiogenic helium from this decay process is also still present within these crystals that are typically only a few micrometers across. However, based on experimentally measured helium diffusion rates, the zircon helium content implies a timespan of only a few thousand years since the majority of the nuclear decay occurred. So which physical process is more trustworthy—the diffusion of a noble gas in a crystalline lattice or the radioactive decay of an unstable isotype? Both processes can be investigated today in great detail in the laboratory. Both the rate of helium diffusion in a given crystalline lattice and the rate decay of uranium to lead can be determined with high degrees of precision. But these two physical processes yield wildly disparate estimates for the age of the same granite rock. Where is the logical or procedural error? The most reasonable conclusion in my view is that it lies in the step of extrapolating as constant presently measured rates of nuclear decay into the remote past. If this is the error, then radiometric methods based on presently measured rates simply do not and cannot provide correct estimates for geologic age. But just how strong is the case that radiometric methods are indeed so incorrect? There are dozens of physical processes which, like helium diffusion, yield age estimate orders of a magnitude smaller than the radiometric techniques. Many of these are geological or geophysical in nature and are therefore subject to the question of whether presently observed rates can legitimately be extrapolated into the indefinite past. However, even if we make that suspect assumption and consider the current rate of sodium increase in the oceans versus the present ocean sodium content, or the current rate of sediment accumulation into the ocean basins versus the current ocean sediment volume, or the current net rate of loss of continental rock (primarily by erosion) versus the current volume of continental crust, or the present rate of uplift of the Himalayan mountains (accounting for erosion) versus their present height, we infer time estimates drastically at odds with the radiometric timescale.16 These time estimates are further reduced dramatically if we do not make the uniformitarian assumption but account for the global catastrophism described earlier. There are other processes which are not as easy to express in quantitative terms, such as the degradation of protein in a geological environment, that also point to a much shorter timescale for the geological record. It is now well established that unmineralized dinosaur bone still containing recognizable bone protein exists in many locations around the world.17 From my own firsthand experience with such material, it is inconceivable that bone containing such well-preserved protein could possibly have survived for more than a few thousand years in the geological settings in which they are found. I therefore believe the case is strong from a scientific standpoint to reject radiometric methods as a valid means for dating geological materials. What then can be used in their place? As a Christian, I am persuaded the Bible is a reliable source of information. The Bible speaks of a worldwide cataclysm in the Genesis Flood, which destroyed all air-breathing life on the planet apart from the animals and humans God preserved alive in the Ark. The correspondence between the global catastrophe in the geological record and the Flood described in Genesis is much too obvious for me not to conclude that these events must be one and the same. With this crucial linkage between the biblical record and the geological record, a straightforward reading of the earlier chapters of Genesis is a next logical step. The conclusion is that the creation of the cosmos, the earth, plants, animals, as well as man and woman by God took place, just as it is described, only a few thousand years ago, with no need for qualification or apology. But what about light from distant stars? An entirely legitimate question, then, is how we could possibly see stars millions and billions of light years away if the earth is so young. Part of the reason scientists like myself can have confidence that good science will vindicate a face-value understanding of the Bible is because we believe we have at least an outline of the correct answer to this important question.18 This answer draws upon important clues from the Bible, while applying standard general relativity. The result is a cosmological model that differs from the standard big-bang models in two essential respects. First, it does not assume the so-called cosmological principle and, second, it invokes inflation at a different point in cosmological history. The cosmological principle is the assumption that the cosmos has no edge or boundary or center and, in a broad-brush sense, is the same in every place and in every direction. This assumption concerning the geometry of the cosmos has allowed cosmologists to obtain relatively simple solutions of Einstein’s equations of general relativity. Such solutions form the basis of all big-bang models. But there is growing observational evidence that this assumption is simply not true. A recent article in the journal Nature, for example, describes a fractal analysis of galaxy distribution to large distances in the cosmos that contradicts this crucial big-bang assumption.19 If, instead, the cosmos has a center, then its early history is radically different from that of all big-bang models. Its beginning would be that of a massive black hole containing its entire mass. Such a mass distribution has a whopping gradient in gravitational potential which profoundly affects the local physics, including the speed of clocks. Clocks near the center would run much more slowly, or even be stopped, during the earliest portion of cosmic history.20 Since the heavens on a large scale are isotropic from the vantage point of the earth, the earth must be near the center of such a cosmos. Light from the outer edge of such a cosmos reaches the center in a very brief time as measured by clocks in the vicinity of the earth. In regard to the timing of cosmic inflation, this alternative cosmology has inflation after stars and galaxies form. It is noteworthy that recently two astrophysics groups studying high-redshift type Ia supernovae both concluded that cosmic expansion is greater now than when these stars exploded. The article in the June 1998 issue of Physics Today describes these “astonishing” results which “have caused quite a stir” in the astrophysics community.21 The story amazingly ascribes the cause to “some ethereal agency.” Indeed, the Bible repeatedly speaks of God stretching out the heavens: “O LORD my God, You are very great … stretching out heaven as a curtain” (Ps. 104:1–2); “Thus says God the LORD, who created the heavens and stretched them out” (Isa. 42:5); “I, the LORD, am the maker of all things, stretching out the heavens by myself” (Isa. 44:24); “It is I who made the earth, and created man upon it. I stretched out the heavens with my hands, and I ordained all their host” (Isa. 45:12). As a Christian who is also a professional scientist, I exult in the reality that “in six days the LORD made the heavens and the earth” (Exod. 20:11). May He forever be praised.
