Hi Peter, everyone.
It was a long time ago that I read it but the way
I remember it was you used up most of the galaxy
to put a sphere around the galactic core.
The
floor was glass to let the light thru.
Wait - which side of the sphere is the floor? And what light is this?
The galaxy's stars would be generating their own light, so it seems
like the only reason to make it transparent would be so the
inhabitants would have more pretty lights in the sky at night.
Gravity held the air against the floor, with
everything being in almost free fall.
I don't get it - where's the gravity coming from?
You put
small planets and moons on various velocities,
give then another push every few thousand years
and use extreamly low powered space ships to
fly to bunches of worlds near by.
If there's air all the way, no reason to bother with space ships. You
could just use balloons (probably zeppelins would be best). Or flying
carpets. Or that swan-chariot idea. Or heck, a pedal-powered glider
would be cool. Though space ships are cool too.
I'm not arguing for the practicality of ANY of
this by the way...
Warm regards, Rick.

That would be the one galactic moon?
Is it a Dyson sphere around all the moons of all the planets of all
the systems in the galaxy, brought out to orbit the galactic Dyson
sphere?
Just wondering...

Hi Denis, everyone.
I read about an idea for a Dyson sphere around
a whole galaxy. The gravity gradient was so
low that you actually could ride a chariot
pulled by swans to the moon...
