That’s a fake-out title. Mainly because it seems to me that while space technology seems to be advancing, and supposing we could go traipsing off to Mars, or elsewhere, there seems to be a miscomprehension by these geniuses of spaces about actually how life survives, or how it evolves. Actually, maybe they should all take a primer on current evolutionary understanding. Or maybe I shouldn’t even concern myself and just let them go off and “learn the hard way.”
But here are some questions that present themselves to me. We know a few things about humans that have been in space for some time. One thing we know is that lower gravity affects bone density. Another thing we know is that there is some organ shrinkage. And a third is that we cannot procreate. At least not in the normal manner. The reduced gravity makes actual physical touching minimally possible, so there needs to be tools used for simple grasping of even small objects that can be simply picked up with our hands in heavier gravity. So intercourse as a method of propagation is not possible. So semination would need to be artificially induced. And poor Elon Musk who believes his superior intellect requires him to be god’s gift to women or is he simply god, a jupiter casting his seed on mortals to create half-gods?) might not really like being on Mars for very long. Some have suggested we might trying to use some kind of attachments to the two bodies to hold them together long enough to have intercourse. NASA has mostly ignored such suggestions, seeming to think sex in space is a no-no subject and something they cannot experiment with in space shuttles. After all, we don’t want to make space stations seem to be den of iniquities, do we? Well that was very nearly the reply used when some scientists suggested that such experiments needed to be carried out before trying to colonize other planets.
But let’s suppose we do go to Mars. Let’s suppose a group of humans and some foodstuffs are actually taken successfully to Mars. simply due to its mass, Mars’ gravity is less, and proponents that we could somehow increase the gravity seem to be misunderstanding that even if we could create some gravitational bubbles to live within, the technology to maintain some shields that are greater than the surrounding gravitational mass at a constant level would be enormous—-it could result in some type of gravitational transference that would collapse the shields, or it could lead to a variety of other possible mishaps, and of course it would be the first step in reversing the current Martian environment to adapt itself—-
Now Musk has suggested a gravitational shield around the entire planet, but to do so successfully we would have to increase the internal mass with some type of artificial mass. The increased mass and weight would destabilize the orbit and increase the likelihood of causing an effect on all of the planetary bodies in our solar system.
But supposing all of that could be figured out, well evolution just wouldn’t allow us and whatever “lifeforms” to just continue existing as they existed on earth. Whatever effect we had on the environment in transforming would also have an effect upon us. Our organs, our skeletons, and more than likely our organs that give us our cognizance would need to evolve. And so those humans who might successfully survive on Mars, well they would not be humans, but the descendents of humans who had evolved into a species that could survive on Mars.
Well that’s a question I have not yet seen discussed. But my question is, why not? because we know that species on earth evolve frequently en masse when environmental transformations occur on earth, why would we somehow imagine it would be different elsewhere?
