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 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!

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.

If one asks a scientist why some dinosaurs reached enormous proportions, on the order of 60 tons, 80 tons or more, the response will be that of "one hand clapping." If there is a response, it will be something like "they got big because they could" or "there was a lot more vegetation for them to eat back then." In other words, they just don't know and the possibility that the Earth's surface gravity could have been less during the reign of the dinosaurs seems too far fetched to them. It is not that it is counterintuitive to them, it's just that they have not been able to conjure up a mechanism by which that gravitational change could occur.

Expanding Earth theorists proffered one such mechanism. They assert that the constant bombardment of the Earth by extraterrestrial debris, including meteorites, has gradually increased the Earth's mass and thereby increased the surface gravity. Scientists have rejected this theory because the mass of the accreted material would be insignificant.

The theory published in this book is a novel one. It accounts for the change in surface gravity by a shift in the Earth's massive iron core. This is a more rational explanation because, as Isaac Newton explained, a change in the gravitational force between two objects is influenced by a change in the distance between them to a much greater degree than a moderate change in the mass of either of the two objects. What caused the core shift? The theory presented in this book posits a linkage between the position of the continental land masses and the core shift, and therefore, the Earth's surface gravity.

Dinosaurs began their domination of the Earth when the continental land masses came together to form the super-continent Pangea. They endured to the period when Pangea had split apart and the continents began to drift to their current positions. Is this just a coincidence? The theory presented believes that there was a convergence of two factors which caused the extinctions of the non-bird dinosaurs. First, increasing surface gravity gradually reduced the physical size and numbers of dinosaurs and second, as a result of the first, the mammals were able to expand, increase in size, compete with and eventually displace the non-bird dinosaurs. No asteroid or volcano needed here! In fact, the theory explains why the volcanic activity happened near the end of the dinosaur period; it was initiated by the core movement.

Going back to the pre-dinosaur times, the continents were in various configurations which were much different from Pangea or the current distribution of land masses. The current theory also attributes the mass extinctions of the earlier periods to surface gravitational changes induced by continental movement. If correct, the Gravitational Theory of Mass Extinction has ended the debate on the Big Five Mass Extinctions.
