> But considering humans survive surprisingly well in micro-gravity in space Source for that claim? The number of studies I’ve read (as well as conversations I’ve had with astronauts) about the health impact on astronauts who’ve been on the ISS for extended periods seems to disagree.

Is less gravity the only difference in being on earth and being on the ISS?

    Why are you attributing it all to the lack of gravity? Losing muscle mass is one thing, but what about the increased high frequency deionizing radiation that astronauts face?

      Because the scientists and medical professionals claim that it's related to the lack of gravity and provide evidence of why that is the case. Do you have a better approach, if so, why not publish based on your more knowledgable expertise?

        Correct, but how does any of them counter what I said? They don’t!
