With the final frontier ahead of us, our crowded world loses its Earthly appeal and seems to only regain it when viewed from the surface of its little sister Luna.
Not even our own immune system is not safe from the ravages of micro gravity.
While either of these paths would enable us to dwell among the heavens in some form or fashion, one may be too expensive to replicate across our star system while the other may be riddled with side affects.
Neither of these would allow us to thickly populate our solar system in an efficient manner, forcing our young race to remain near our birth planet.
In order for our species to live, breed and raise children off world, we are going to have to figure out an inexpensive and healthy way to raise our future young on other terrestrial bodies.
So instead of trying to alter our environment (or worse, our bodies) for “Earth norm” gravity, why not simply require future children to wear gravity suits?
A gravity suit would simply be a weighted suit that would simulate Earthen gravity by having the appropriate kilograms (or pounds) placed within the suit. These weighted suits would strengthen a person’s muscles and bones, which would help fight against them suffering atrophy (for adults) and help kids muscles develop normally.
Gravity suits would also present kids born off world with the opportunity to visit Earth without worrying if their bodies could handle the pull from the home worlds gravity.
While other scientific and medical instruments could be added to the suit (for whatever practical reasons), simple weights could enable our species to not only explore other worlds, but live upon them as well.
