GREETINGS FROM A NEW MENBER & IDEAS FOR THE ATMOSPHERE IN ISLAND ON

I believe to have understood that problems could exist with the mass of the atmospheres inside the space cities, because a bigger mass implied bigger difficulties to be retained inside a closed structure and in rotation in the one emptied space, the centrifugal force would push toward it was the mass of air and the pressure of the atmosphere would increase what would create problems when maintaining it closed inside the structure of the space city, Just a minor point. In truth, the centrifugal force adds little to the air pressure inside. The stresses on a non-rotating sphere of same size and pressure would be very nearly the same.
