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?
That’s why you split the ship in two and spin the habitation module around the heavier part of the ship¹, connected by a tether, as in Project Hail Mary (which the video says is still too fast… so just make the tether longer).
Yeah, a good idea. You run into some material strength issues, but I think this is the way.
