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 the 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 the magnitude and direction of chirality. In this work, the changes in isotopes alter gravitational effects on the 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 the earth’s gravitational field is reduced by travel away from the 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 were reasoned in this work to cause lightning. Such solvents 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 the 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 the lack of charge accumulation and discharge for explaining lack of lightning on Venus. The lower temperature (−214 °C) and raining N2 (boiling temperature of −210 °C) in Neptune were 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 climate (−193 °C) of 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 the charged atmosphere of Neptune to Sun’s magnetic field.
