I’ve always known about this argument regarding the Mars effect. Basically, the difficulty lies in defining in objective terms what constitutes eminence in professions. I found Gauquelin’s work on planetary heredity links much more interesting, as it dealt exclusively with hard data-time, place of birth, and the planetary positions for both parents and child. In those studies, it was shown that, if a certain planet in a parent’s birth chart was placed in a Gauquelin planetary zone of influence (see Fig. 2), the child showed a tendency to be born with a similar planetary placement. So these new objections to Gauquelin’s work are limited, in my view, because they totally ignore the planetary heredity effect.
Gauquelin’s studies also showed that on days when the geomagnetic index was high, the planetary heredity effects of Venus, Mars, Jupiter, Saturn, and, to some extent, the Moon, were enhanced (see Fig. 3). This seemed very significant to me because geomagnetism is known to rise during periods of heightened solar activity. The level and intensity of solar activity waxes and wanes within the eleven-year solar cycle, also called the sunspot cycle. My theory proposes that certain planetary alignments affect solar activity. Thus, the build-up of sunspots within the solar cycle can be accounted for by the complex interactions of planetary forces acting upon the Sun’s magnetic field, which in turn affects Earth’s magnetosphere. (A sunspot is a dark area in the Sun’s photosphere, or visible surface layers, that is associated with strong magnetic fields.)
This brings us to another intriguing aspect of Gauquelin’s planetary heredity work that his critics often ignore, and which fueled my interest in astrology-the fact that the four-pronged pattern, involving two large peaks and two small peaks, that emerges for Venus, Mars, Jupiter, Saturn, and the Moon, is very similar to the shape of the average lunar daily magnetic variation for one month. Earth’s magnetosphere (see Fig. 4) contains a wide range of frequencies, one of which we know is connected to the Moon, and is well known to geophysicists. This lunar daily magnetic variation is caused by the Moon tugging at the layers of plasma, or charged particles, trapped in Earth’s magnetosphere. When this plasma is dragged around by the Moon’s tidal forces, it causes variations in the atmospheric pressure at ground level, and these we can measure. So, this resemblance between Gauquelin’s four-pronged pattern for Venus, Mars, Jupiter, Saturn, and the Moon and the pattern for the monthly average of the lunar daily magnetic variation suggested to me that the tidal tugs of the planets were in some way disturbing Earth’s magnetosphere, just as the Moon and Sun are known to do. I began to suspect the existence of a daily planetary magnetic variation, different for each planet, which might account for Gauquelin’s planetary maximums all falling into this same four-pronged pattern.
