The Earth Is Expanding And We Don't Know Why

"The geological and geophysical implications of such Earth expansion are so profound that most geologists and geophysicists shy away from them. In order to fit with the reconstruction that seems to be required, the volume of the Earth was only 51 per cent of its present value, and the surface area 64 per cent of that of the present day, 200 million years ago. Established theory says that the Earth's interior is stable, an inner core of nickel iron surrounded by an outer layer that behaves like a fluid. Perhaps we are completely wrong and the inner core is in some state nobody has yet imagined, a state that is undergoing a transition from a high-density state to a lower density state, and pushing out the crust, the skin of the Earth, as it expands."

Now that is serious...more so than Global warming...are we causing this expansion with our constant drilling looking for oil?

In the 1960s oceanography came up with some surprises. First of all, it was recognized that the ocean beds were not filled with miles and miles of sediment, as would be the case if the world's rivers had been carrying silt to the oceans for four billion years. Instead it was found that the ocean floors were geologically new.

The second surprise was the discovery of the Atlantic ridges, a series of parallel ridges which run mostly north and south throughout the Atlantic. The ridges show a series of parallel magnetic reversals of the top layers of rock, matching east and west from approximately the center of the Atlantic. Further research has found the same in the Pacific and Indian ocean, although of a more complex pattern. Geological dates of the ridges also match from the center out. The oldest ocean beds are just east of China, with smaller stretches just off the North American east coast and in the south Caribbean. These regions all date from the Jurassic era, 200 to 150 million years ago.

It looked like the Earth had indeed been expanding, and in fact it looked like there were no oceans before the Jurassic. That means the original land mass (Pangea, the single land mass which had already been suggested as the parent to all of today's continents) must have covered all of the Earth at one time. The start of ocean floor spreading (as it is called) dates from after the first appearance of the giant dinosaurs during the Jurassic.

You can look at a globe and make some simple calculations. Subtracting the estimated spread of the Atlantic and Pacific from the current circumference of the Earth (25,000 miles) gives an earlier circumference of about 12,500 miles. The Earth had roughly doubled in diameter.

Gravity is a function of the mass divided by the square of the radius of the Earth. The mass of the Earth, assuming no change in density for the new material, is a cubic function of the radius. Thus gravity is linearly proportional to the radius of the Earth. As Earth expanded, gravity increased in proportion.
