If I may suggest for deciphering the Voynich manuscript, to use a less conventional approach, such as for a science document, to be more specific DNA experimental histories or curriculum. The science of genetics has abbreviations such as DNA, it has formulas, equations, and the language of science i...

Anomalies such as Venus’s very slow retrograde rotation and resonance with Earth disqualifies the accretion disk theory for our solar system or someone has been messing with our solar system planetary bodies, big time.
