sky with you

you can take sky with you/if you design your spacefaring vessel properly

there’s an expensive way involving a comet core/and a transparent encasing dome/and a huge volume of a mixture of gases

there’s a cheap cheating way/involving LEDs on interior surfaces

and then there’s the loophole/technicality way

and that where when you find your hospitable planet/you simply release some of the air/you brought from you home planet/into the new planet’s atmosphere/and it becomes part of the sky
