According to Dr Percy Seymour, a Theoretical Astrophysicist, resonance is what makes it possible for a radio telescope to tune into specific vibrations in the Andromeda Galaxy (14 million, million, million miles away) and accounts for the Solar System playing a symphony of vibrations on the magnetic field of the Earth. It also foils the arguments of all those who believe that planetary forces beyond the Moon are too weak to have any impact on terrestrial life. Resonant Theory states that even small fluctuating forces can have large consequences, if the frequency of vibration coincides. This supports the main tenet of astrology, which is that personalities of individuals are related to the state of the Solar System at the time of birth*

Dr Seymour believes that the resonance between the tidal tug (due to gravity), of the very hot gases trapped in the magnetic field of the Sun and Earth, and resonance between the resulting fluctuations of the Earth's magnetic field and the electrical activity of the neural network in the brain, are what link celestial firmly to terrestrial.

Basically Dr Seymour confirms the theory of harmonics put forward by John Addey in 1975: All astrological effects can be understood in terms of the harmonics of cosmic periods. This frees astrology from its somewhat limiting twelve-fold straightjacket and allows us to understand how new planets can be discovered without changing the fundamental basis of astrological thought and practice. Resonant theory (harmonics) is the Holy Grail for astrologers because there is no astrological doctrine in classical or modern astrology which cannot be explained by it.
