The Earth we lived in has a invisible force of magnetic field, also known as the geomagnetic field. This magnetic field extends from the Earth’s interior out into space, emitting from the South Pole to the North Pole.
The Earth’s mantle is composed of iron-magnesium silicates, and the crust is composed of roughly 5 percent iron. All together, iron makes up an estimated 35 percent of the Earth’s mass.
With the environment made up of particles of iron, the geomagnetic field in turns gradually affects the movement of ocean floors and tectonic plates causing landforms, earthquake, mountains and continents.
In the human body, there is blood. In blood, there is small percentage of iron. Which is also affected by geomagnetic field, gradually over time The study of Feng Shui seek to tap on the positive Qi (stable geomagnetic fields) and avoid the negative Qi (fluctuating geomagnetic fields).
Therefore, I couldn’t say that there is absolutely no Science in Feng Shui to begin with.
