What if humans were born and raised in space? What would they look like, what health problems might they encounter? I take a scientific look at The Expanse and find what all fans already know...it's brilliant. [no spoilers] ------------ Music: Huge thanks to NAVIKMusic for allowing me to use his performance of the Expanse Theme (by Clinton Shorter) and subsequent original composition by NAVIKMusic. Check out his channel here https://www.youtube.com/channel/UC3BNmWdzS094ja3IF2d-emA ------------ More Medlife Crisis: http://www.medlifecrisis.co.uk/ https://twitter.com/medcrisis https://www.facebook.com/Medlifecrisis https://www.instagram.com/medcrisis ------------ I could’ve gone into a lot more detail about each topic and I already chopped out about 5 minutes. In reality it’s more complicated, especially the skeletal growth. For example, paralysed children who are bedbound from a young age still grow to a fairly normal height. Bedrest is used as a cheap Earth-based analogue for microgravity, but there is a fundamental difference between this model and the theoretical effects of literally growing up in space, namely that children will be mobile and likely to suffer repeated fractures of their osteoporotic bones. Also, I know Belters might spend good portions of their lives in environments with low, but not absent, gravity, like Ceres. We don't know if there is a cut off at which point biological processes are affected. Some gravity is better than no gravity, but we don't know how much we need to stay healthy. How fast would we need to spin the Behemoth? No idea. For simplicity in the video, I just talked about weightlessness but it's likely to be a spectrum. Ganymede’s magnetosphere is mentioned as a possible reason it is more suitable for human colonisation. However, its close proximity to Jupiter, with a much stronger magnetosphere, might make this irrelevant. And yes, I say “mag-neeto-sphere” because it sounds like Magneto and that’s COOL so shut up.
