I am building a habitable, Earth like planet, but instead of it being in a solar system, it is inside a Nebula.
The actual composition of the Nebula is uncertain at this point, but I am considering something like the Orion Nebula.
Imagine if there was a vast cloud of gases, similar in composition to the gases that make up our atmosphere, that covered the Earth and the Moon and everything in between.
Would this make traveling to the Moon easier?
Could modified Balloons and Dirigibles be used for short range space flight? If gases lighter than the gases of the nebula were used inside Balloons, in what direction would they "rise"?
Would the nebula open up new forms of space transport? Could the clouds and dust be used as propulsion, or at the very least, something to push against in space?
