can't sleep. mind is in visualization mode.
on the moving sphere, because of its
unlimited thickness,
it wouldn't be affected by the pressure of
water beneath the ocean i'm thinking.
opportunity to explore?
but to refine the # of 'rings'.
if you see a circular mirror,
there are designs in which they are held
to its two sides at its very edges.
what if the base of that two frame rotates
in a circle as well,
and for the ring that is held by the frame,
obviously it is fixed in its position,
but. second ring a layer below it, need not be.
creating all directional 'force' to move the sphere.
and if the sphere, under the ocean floor
is a dodecaheron (?) or something like that,
may help incrementally move forth.
maybe similar concept in different situation
can be used in other planets who knows.
just imagination........ ok now i sleep.
