Rotation. For long-term inhabitance of micro-G environment, we need
centrifugal force in large to very large structures that rotate or are round
in nature. Hollow Donuts, Hollow Spheres, hollow cylanders--all larger then
anything we have ever had in space is need. Its tricks the cells that
comprise living matter to behave as if its subjected to a gravity field. The
heart pumps and blood pulls against a downward force, to be circulated back
thru the upper extremities and head. Chewed food gets pulled down to the
tummy (as with gravity) through centrifugal force (inertia). We need huge
structures in space to sustain biotic life. Silicon life or Biosilicate life
certainly will faire better.
