Inventions and Deceptions – Gravitational Mass Attraction

This gallery contains 6 photos.

The fundamental basis of mainstream Gravitational Theory is that physical bodies generate an attractive “force proportional to their masses”. Gravitation, or gravity, is the natural phenomenon by which physical bodies appear to attract each other with a force proportional to … Continue reading

Planetary Rotation 2: The Gas Giants

This gallery contains 5 photos.

The first part of this post found a statistical relation between the planetary period of rotation [in days] and the diameter [in kilometres] for the Gas Giants of the Solar System. However, describing this statistical relationship in more detail is … Continue reading
