It is a supplement to the book entitled „Unknown Earth – unknown hypotheses” (https://amzn.to/4dPba3s).
If we assume that the inner core consists of two fused spherical cores, the varying gravitational force would be many times greater than the gravimeter measurements indicate. This difference can be seen in the graphs at the beginning of the RESULT spreadsheet in the attached file.
The gravimeter data are contained in the attached file igets.u-strasbg.fr-1911.
In sheet B, column D marks the measured minima of the Earth’s gravitational acceleration, while column H lists the calculated minima of the gravitational force resulting from the displacement of the longitudinal inner core relative to the Earth’s surface.
In column K, you will find the absolute values of the time differences between the measured minima of gravitational acceleration and the calculated minima of gravity variations caused by the core.
In cell K3, we can see that the average time difference between the measured and calculated minima of the Earth’s gravitational acceleration is less than one hour (the calculations were performed at one-hour intervals).
