Men are from Mars and women are from Jupiter?
It’s an intriguing theory.
Jupiter and its moons are a billion miles from the sun — more than ten times Earth/Sun distance. Surface temps on Ganymede vary between -170 to -290 Fahrenheit. Water at that temperature doesn’t just freeze — it rivals steel in terms of strength. Ganymede may have liquid water beneath the ice layers covering its oceans from geothermal sources. But on the surface? Not a chance.
My understanding is that Jupiter has such strong radiation emanating from it that life as we know it could not exist.
But, then, there’s Europa…
From page 79
“the most likely scenario for early humans to have gotten to earth [From Ganymede] involves an electrical water bridge and a splash saltation event that most likely would have landed those early humans in the waters of the Pacific Ocean. On their own, they most likely would all have drowned. Our working assumption is that they were assisted by other aquatic mammals with whom early humans had symbiotic relationships, and the most likely large body of land for them to have ended up on would have been Australia.”
Very creative novel.
