Fermentative productions of amino acids are thought to retain homochirality. This work can propose rotational motions for accelerations by centrifugations during fermentative processes enrich heavier, stable isotopes of differing nuclear magnetic moments (NMMs) with consequent possibility of altered chirality and magnitude of rotating polarized light for altering chemical, physical and biological phenomena of such enantiomers. The author discovered gravity seeding homochirality. Thereby in this work, the author determined that altered gravity can change magnitude and direction of chirality. In this work, the changes in isotopes alter gravitational effects on metabolism of enantiomers in hosts eating fermentative produced amino acids. Cancer was determined from eating heavier isotopes from fermentative processes and cancer cells were reasoned in this work to be more affected as earth’s gravitational field is reduce by travel away from earth’s surface. Similarly accelerated motional and gravitational effects on isotopes in planetary atmospheres of Earth, Saturn, Jupiter, and Uranus by 14N, 15N, 1H, 3He, 13C and 17O was reasoned in this work to cause lightning. Such solvent of positive NMMs were reasoned by collisional exchange to accumulate and exchange charges in clouds and collisional exchange solute negative NMMs were reasoned to alter charge for production of leaders and streamers to induce lightning strikes. Lack of sufficient 13C and 17O in the CO2 of Venus’ atmosphere is explained in this work to mediate lack of charge accumulation and discharge for explaining lack of lightning on Venus. The lower temperature (-214 oC) and raining N2 (boiling temperature of -210 oC) in Neptune was reasoned in this work to strips 15N from the atmosphere of Neptune for explaining its lack of lightning despite its similar atmospheric composition but warmer (-193 oC) as Uranus. The charged 1H atmosphere of Neptune is thereby the basis for charging Neptune’s atmosphere and the author thereby explains the disappearance and reappearance of Neptune’s clouds by magnetic coupling of charged atmosphere of Neptune to Sun’s magnetic field.
