1) How much the core would have to move to significantly affect the surface gravity on one side of the planet.
2) What amount of force would cause that much mass to move in the first place.
First of all, all three core elements moved. The resulting surface gravity reduction would be determined by the amount of movement. In the book, with
the same name as the theory, a calculation is done using a 50% reduction in surface gravity resulting in a movement of about 1/4 of the diameter of
Your second question about what force would be required to move the core elements is confusing. The movement of the core elements is a response to
maintain the Earth’s total angular momentum.
3)Then you'll need to show that dinosaurs bone density was different than say elephants of today (from what we know of biology, organisms evolving in
a higher gravity field would have a higher bone density than those who evolved in a weaker gravity field.
This is an assumption on your part unless you have data on animals that have evolved in a lower gravity environment.
4)Then show why over 40 million years later, there were mammals who also reached gigantic proportions, some the size of T-Rex (only 20 million years
The theory, if you read the PDF, explains this. The position of the core elements (either 1,2 or all 3 of them) depends on the position of the net
center of mass of all continental masses relative to the equator. Whether all continental masses are combined (as in Pangea) or broken apart the same
rule applies. Therefore, for example, when Indricotherium existed about 30-35mya, the Earth’s core elements had moved further away from
Earth-centricity than they are today. It is no coincidence that at that time worldwide sea levels rose to very high levels (which is an indication of
lowering of surface gravity levels as explained by GTME).
5)Pangaea existed 510 to 200 million years ago. Then between 200 to 180 million years ago, it broke up into Laurasia and Gondwana. Another super plate
existed prior to Pangaea called Rodinia.
Your dates are a little misleading. Pangea gradually formed from about 350mya to 300mya (see www.scotese.com). 200mya was the initial fracture which
started the breakup and forming the beginning of the Atlantic Ocean. It still remained basically a supercontinent into the Cretaceous (although pieces
were starting to separate then. In other words, even though continents were separated by small distances, relative to today, their effect on changes
in surface gravity was still strong.
6)During the Jurassic period (200 to 145 million years ago) you have many large dinosaurs. However, after the Jurassic, going all the way to the late
Cretaceous (up to 65 million years ago) you had T-Rex around.
The Jurassic Period is when the largest dinosaurs appeared (in the western USA) and in that region they began to get smaller in the Cretaceous (in
that region). T-Rex was around to late in the Cretaceous but did not make it to 65mya.
7)You will also have to explain why certain mammals grew large after this period, for about 35 million years. A good example of that is the
Hydracodontidae family, that ended up growing to huge mega mammals such as the Indricotheriinae.
See my response to 4) above.
8)The reason you need to explain the last one is: if the Earth's core had moved, increased gravity on one side, but making surface gravity weaker on
the other side, and the main evidence for this is mega growth of animals on the land surface of the Earth, then it did this and stayed that way for
over 200 million years. Yet during that time, Pangaea broke up, and those different plates drifted apart.....meaning that the fauna that lived on them
would not have stayed only in the weaker gravity field to grow to huge sizes.
When Pangea existed surface gravity varied from low to close to what it is today. If you read the PDF, the strength of surface gravity coincided with
the position of Pangea’s center of mass relative to the equator. Therefore, as Pangea’s COM moved from well below the equator onto the equator
about 260-250mya, surface gravity increased to close to what it is today. See the graph at the end of the PDF, the date comes from the French study of
magnetic reversals). Therefore, surface gravity did not stay the same for 200 my.
As the plates broke up, the lowest surface gravity would be in the (equatorial) region with the largest net continental mass. It’s not easy to
estimate exactly where this would be but logically since the African/Asian continental mass was probably the largest, I would guess that this
equatorial region maintained the lowest possible surface gravity well after the breakup of Pangea. This is probably why Indricotherium existed closer
to that region than in either North America or South America.
