      Idk if mine has adapted to normal gravity tbh. I accidently cracked an egg into my trash can today

      Unsurprising. It’s completely unlike life on Earth. Makes me discouraged about space travel

      I know this isn’t fair, but it kinda feels like half the science nasa does is basically saying “microgravity is really bad for you”. like, okay, we have fully determined that….y’all ever gonna start doing spin gravity testing to see how much gravity we need to avoid the bad health effects? feels kinda crazy it’s been over 60 years and there are no experiments planned to do that.

      The article is way less dramatic than the title seems to be, and nothing surprising.

      But I do wonder though, if humans manage to colonize Mars to the point of having people be born and raised there, how could their bodies grow differently in a lower gravity.

      >Bringoux says that this finding suggests “astronauts tend to apply a larger safety margin” than is strictly necessary for holding on to and moving objects to prevent any unexpected slips. It also suggests that astronauts reach an “optimal” level of adaptation to their weightless surroundings—their sensorimotor skills change enough to ensure they can safely and accurately hold on to and move things around in microgravity but not more than that.

      I was expecting actual medical implications, but I’m not seeing the issue here? How is reaching „optimal“ isn’t a sign you can’t adapt?

      This just feels sensible when dropping something might mean serious efforts to get it back.

      If accidentally dropping a glass meant I risked a storm of razor sharp pieces of glass floating around in my living room for years, I might be more inclined to keep a tight grip on things.

      If you drop something in space it doesn’t stay at your feet. Moving stuff is risky.

      The premise of this experiment is totally wrong.

      Author of the experiment is suggesting that the way astronauts interact with floating objects indicates some deep primordial brain behaviour about dealing with microgravity.

      Don’t disagree, but the author seems to have a bad control group: people who intricately know and have been trained about the dangers of floating objects and react accordingly.

      I would also be stressed and grip things slightly harder and faster if placed in a similar position on Earth.

      So, the end result is… useless knowledge.

      Damn that stinks. So I guess we’ll definitely need giant anti-gravity centrifuges as well as vacuum-like sleeping bags or something that pulls blood away from the brain from time to time. Hopefully they can figure it out, otherwise that’d be pretty depressing.

      I’d imagine it takes quite a bit longer than they usually stay in space to adapt to an environment completely unlike any on the planet our species evolved on

      I wonder if exposing children to various g-force values regularly would help them better adapt to variations, and potentially become “fluent” in motor skills for low or even high g as adults. And if so, to what extent? Obviously hard to test though unfortunately.
