Someone recently brought up Dison Spheres, and the Relics episode connected
with it.. I remember being struck by the possible ramifications of a
Starship suddenly coming up through the surface of the earth and going into
some sort of orbit high above.. I thought, what kind of speed where they
pulling through there, and what about atmospheric friction.. what kind of
power would be needed for a force field to keep the atmosphere from rushing out
into space while the door was open.. Then I began to think, what was keeping
the atmosphere, and everything else for that matter, on the inside of the
sphere. From physics we learn that spherical shells impart no net gravitational
attraction to objects within them, so that is ruled out.. I would think that
Artificial gravity of the sort that the Enterprise uses would be ruled out due
to prohibitive cost.. So I figured some sort of "centrifugal" force might
account for it.. that would make the sensation of gravity, however a
function of distance from the equator, and thus there would be no atmosphere
or 'gravity' at the poles, making for uninhabitable regions. If this were
the case, then they would make ideal locations for portals, as there would be
no atmosphere to worry about nor any nearby inhabitants...
Another thing of consideration would be the solar wind put out by the star..
what would they do with that effluence, maybe solar wind would keep the
atmosphere there, but not the people, and further, I doubt it would be all
that great for the composition of the atmosphere.. You would have to worry
about the sphere "popping" :)... or maybe they could put the vents at the
poles along with the portals, creating possibly trade winds emminating from
the equatorial regions (I don't know what scale these would be, as I do
not have sufficient information to hazard a guess as to interactions between
terrestrial atmospheres and solar wind on that kind of scale.. ) Anyway, just
some things to think about.. Any more ideas on practicalities of Dison Spheres?
