Mine hit me with the “We’re spending all this money on you now so you can’t grow up and say we didn’t spend money on you when your were a kid.”
Well that’s how it works in Larry Niven’s Ringworld and also Halo. They just thought the earth was a ring.
Halo arrays and RIngworld work because objects in frictional contact with the inner side of the boundary material are imparted linear velocity by the motion of the structure, that’s not at all how it works on planets.
Even if Earth were tide locked to the sun it would still have the same exact degree of pull on other mass-having bodies. A ring array that stops spinning has occupants who experience free fall
Here’s another fun fact: A ringworld exerts zero net gravitational force on anyone inside of it. It’s one of the implications of shell theorem.
not exactly true, a sphereworld this would be thecase
Around the edges of the ring structures you would get minute tidal effects
Not if the ring curves inward at the edges, conforming to a section of a sphere.
Which neither the HALO arrays or Rimworld do…
It was either in one of the books or an easily missed line in Halo 1, but the Halos actually don’t spin fast enough for the amount of surface gravity they have, implying artificial gravity is involved.
