We all know the pictures of the astronauts on the ISS floating around. We also suspect that a lack of gravity is bad for the body as the muscles go weak and such.
Why don’t spaceships just rotate to cause the effect of artificial gravity through centrifugal forces?
Basically, the spinning diameter has to be really long so the spinning doesn’t make you puke long-term (Coriolis force is a bitch). There were NASA tests and studies about it, which range between a 100 and a 1000 meter diameter.
So, the ship has to be built for it from the design phase, be it with a rotating ring or a tether approach. Which we didn’t have yet a usecase for (for only a few days or months):
Not a word, my dude. When your spell check wants to put a hyphen or space in, let it.
That’s the wonderful thing about a living language, if enough people start using a new word or a variation on the spelling of an existing one, it can simply become correct at a point.
The compound variant ‘usecase’ is often used in tech and refers to a very specific means in which a system is utilized.
