A new unified theory of mass extinction that identifies the primary cause for the 'Big Five' mass extinctions as a gravitational one. The theory proposed in this book posits a lowered surface gravity as a result of the coalescing of the continents that formed the supercontinent Pangea. The linkage of continental tectonic plate movement and the shifting of the Earth's inner iron core is described and is the underlying basis for changes in surface gravity. The gigantism of the sauropod dinosaurs and other Mesozoic life forms are attributed to reduced surface gravity as well as their gradual extinction as Pangea broke apart, resulting in increased gravitation. The rapid fall and rise of global sea levels during periods of mass extinction, unexplained by current mass extinction theories, is readily explained by this theory. The diverse morphological changes of the ammonites during the late Mesozoic Era are posited as an evolutionary response to increasing surface gravitation. The theory explains the coincidence of massive flood basalt volcanism and extinction periods as well as the uncanny coincidence of volcanism, bolide impact and extinction at the K-T boundary.

False representation of gravitational physics, pretending to be science,
By
This review is from: THE GRAVITY THEORY OF MASS EXTINCTION: A New Unified Theory of Mass Extinction Explains The Rise and Fall of The Dinosaurs (Paperback)
Although we are still working out the quantum mechanics of gravity, a few scientific facts are not at all in dispute, and one of these is that a celestial body's gravitational field is directly proportional to its mass.
And the Earth's mass has not changed appreciably since the theorized impact billions of years ago which created the Moon. Moreover, however big and massive the continents might seem to be, as compared to the rest of the volume of the planet, they are like the thinnest rice paper on the surface of a basketball. The above-ocean mass of all the continents is but a tiny fraction of a percent when compared to the mass of the entire Earth. As a point of fact, Earth's moon has a greater influence on the surface of the planet, including experienced gravitational fields, than does the mass of the continents. Likewise Earth's rotation (higher perceived gravity at poles, 0.5% greater). Or altitude (400km up, Earth's gravitational field still measures a healthy 8.5m/s2). The currently measured values of gravity at various places around the planet have less than half a percent difference -- which is negligible. Putting all the continents on one side of the planet would certainly result in a different set of gravitational variance anomalies -- but again, no matter how you run the numbers, we're still only talking a fraction of a percent of the entire gravitational field for the planet. And somehow this is supposed to explain why some dinosaurs got so big? (And by the way, the largest animal ever to have lived was no dinosaur, but the extremely contemporaneous Blue Whale (aka Balaenoptera musculus).) Yet this author posits that somehow the planet experienced gravitational fields variances far, far outside the currently measured average range -- without the Earth tearing itself to pieces in the meantime due to rotational wobble, with no particular mechanism to explain how or why this variance happened (sorry, but the continents just aren't massive enough to account for it and the mantle isn't going to suddenly flop to one side for no reason -- and then magically refix itself after a few hundred billion years), and no actual numbers as to how much lower the field strength must've been. The author makes the amateur's mistake of confusing coincidence and false supposition with causality, and looking at his website I see one scientifically unsupportable attempt after another to conflate every planetary extinction event with his uninformed theory. I see nothing in this to suggest Mr. Stojanowski understands physics (basic or astro-), biology, geology, or paleontology, and no mention anywhere of his credentials as an expert in any of these fields. (By the way, the current *scientific* theory is that the break-up of Pangea did quite possibly contribute to the demise of the dinosauroid megafauna -- but because it drastically altered the climate conditions that supported the natural selection of such, resulting in a rather colder, drier environment world-wide.) It's a cute idea, and it's clear there are still plenty of gullible people out there who were badly ill-served by their high-school science classes, but even as science fiction this notion would be turned down as wildly implausible and demonstrably unscientific. This theory is ridiculous and laughable.

The most exciting and innovating extinction theory of the last decade,
By
This review is from: THE GRAVITY THEORY OF MASS EXTINCTION: A New Unified Theory of Mass Extinction Explains The Rise and Fall of The Dinosaurs (Paperback)
"The Gravity Theory of Mass Extinction" will create an enormous earthquake in the field of science!
This is a fascinating book which takes into account the effects that the environment of Pangea would have had on the development of the dinosaurs. There have been many theories to explain the rise and fall of dinosaurs from volcanos to glaciers to meteors. But this is the first work that I know of to give us a serious look at how gravity and plate tectonics may have affected one of the most successful species in terms of longevity in the history of the Earth. Stojanowski has performed a worthy service for all students and lovers of dinosaurs. Three cheers for him!

Impossible!,
By David Dreisigmeyer (Fort Collins, CO United States) - See all my reviews
This review is from: THE GRAVITY THEORY OF MASS EXTINCTION: A New Unified Theory of Mass Extinction Explains The Rise and Fall of The Dinosaurs (Paperback)
This book's premise would violate fundamental physics that has not been in dispute for nearly 400 years. You might as well say that the Flying Spaghetti Monster caused the mass extinctions -- it would be as scientifically valid as this book.
