I am a post-human adapted for permanent life in vacuum and micro-gravity. How might my physiology and biochemistry overcome the following challenges?



Part 1: Radiation:
I am constantly bombarded by ionizing solar and cosmic radiation that punches through matter like little atomic cannonballs. How can I protect myself? How might I sense potentially dangerous increases in radiation, such as from a solar flare?

  • Good Chairman, take a page from @Demigan and his supersoldier idea where s(he) broke up a many paqrt question in several questions. worldbuilding.stackexchange.com/questions/112777/… Your question is actually 5 different questions. I recommend you break them up and post them one at a time with a little time between each, so as to not overwhelm. I have taken the liberty of starting this for you, reducing your question to just the first one about radiation.

Come the technological singularity, humans could be digital and capable of existing in a digital world of their own making.



The computers running these digital worlds can already exist in space. Humans will only have to load into physical bodies if they want to or need to act in the physical world.



You make the assumption that humans would organically adapt to exist in space but that would never happen. Space is too harsh and uncomfortable for humans to want to when they can live in a world of their own design.

    You almost certainly mostly mechanical.



    Life is very adaptable to extremophile adaptation (very hot/cold, highly acidic, heavy metal poisons, radiation, low nutrient availability) but even after millions of years of evolution, the organisms that can live in the most extreme settings are inevitably very simple organisms. For example, there are plenty of lichens in Antarctica but no trees or higher plants, and no permanent resident vertebrates. Bacteria adapt to hot springs, but you won't find fish living in them. There appear to be physiological limits to natural adaption of mammals to very high altitudes.



    So far more practical than trying to bio-engineer a complex air-breathing organism, with a resource-hungry brain, to survive in space - it would likely be much simpler to either:



    • take just the important 'parts' (brain, some glands, some internal organs) and install them in a mechanical 'body' designed with its own radiation shielding, reactor, long-term food supply (or microbial bio-farm that recycles your waste products into food), thrusters, grabbing arms, radar and radio. Or,


    • go the whole hog and download personality into an entirely mechanical 'body'.

      https://m.phys.org/news/2010-04-scientists-multicellular-life-doesnt-oxygen.html



      And thats probably also the end of it. Unless your humanoids have found some system to use uranium or Iron and dissolve that into oxygen. You'd also need to concect as little heat as possible to remain warm, so either become larger which is hard due to the oxygen problem or have a specific metamaterial to keep in your heat.



      For radiation I would use boron nitrate Nanotubes: https://en.m.wikipedia.org/wiki/Boron_nitride_nanotube



      They are already in development for spacecraft.
