I first published the concept of the reduced gravity thesis in my 1994 book Dinosaurs and the Expanding Earth. The concept explains the gigantic size of ancient life like the dinosaurs and this concept is now widely promoted by a number of people.
The reduced gravity thesis advocates that gravity was less on the ancient Earth and this allowed dinosaurs to become gigantic. The size of today’s life is limited by gravity so a reduced gravity reduces the weight of all life and therefore increase the relative size of all life. So for example, the largest carnivore today could become larger in a reduced gravity and the largest vegetarian animal would also be able to become larger. In fact, all life would be able to become larger in a reduced gravity.
Today, there is a whole range of life of a similar scale. Among the grazers there are wildebeest, rhinoceros, elephants, deer and carnivores like lion and tigers. During the dinosaurs’ time a totally different scale emerges. There were sauropod dinosaurs with long necks and tails several times the mass of the largest elephant. Among the largest carnivores dinosaurs were elephant sized Allosaurus and Tyrannosaurus rex. These animals were typical for their age and if the whole cross-section of dinosaurs’ life is compared with today’s life then the scale reduction of today's life is clear. This reduction in the scale of life is explained by a reduced gravity during the dinosaurs time which allowed dinosaurs to reach much larger sizes than is now possible.
The reduced gravity thesis clarifies the dinosaurs’ gigantic size but using the concept of a gravity that increased since the dinosaurs’ time also allowed a fascinating new world where the gigantic animals of the past were forced to evolve into smaller sizes as gravity increased to its present value. This size reduction in life has definitely occurred. After the dinosaurs became extinct, a range of super-giant mammals reached the size of the smaller dinosaurs. Millions of years later came giant versions of today’s life and these have now died out to leave their smaller present day descendents.
One of the key points behind the reduced gravity thesis is that ancient gravity can be calculated from the ancient life since lifes’ optimum form varies in relation to gravity. I defined this relationship in my book as;
‘ For a particular form of life the linear size of land-based life is inversely proportional to the strength of gravity. ’
The reduced gravity thesis was a new concept when I first outlined it in my 1994 book. Certainly I was not able to find any book or papers suggesting a reduced gravity thesis had been proposed before. Today there are numerous people discussing, supporting and advocating a reduced gravity thesis to explain the gigantic size of ancient life. There are now some notable supporters for the concept; Professor Warren Carey was sufficiency impressed by the reduced gravity thesis to include a section about it in his own book, Earth Universe Cosmos, after he had read my own book. Dr James Maxlow was also convinced by the concept and included a section about dinosaurs in reduced gravity in his book Terra Non Firma Earth. Many people have promoted the concept on web sites and Internet discussion groups and some people have been even more successful. Ted Holden appeared on a Japanese TV program and Neil Adams discussed the reduced gravity thesis on American radio. This is all good news for the reduced gravity thesis and I have included links to various other web sites and resources throughout this web site.
