Filling the Solar System with AIR - What would happen? (hackertalks.com)

Let's suppose we could dump enough "breathable" air (whatever that means for humans) into the solar system that it filled the spaces between planets.

What would happen?

A - I imagine it would then become possible to fly airplanes between planets, perhaps balloons? Would space travel become easier or harder?

B - According to another lemmy post, we would start to hear sound waves from the sun (A constant jackhammer sound - delightful)

C - Each each planet become the center of some mega cyclone (like the Jupiter storms, but bigger)?

D - At some point the air above us wouldn't be pushing down onto the earth at sea level, could we survive the additional pressure?

Well, it wouldn't change the gravitational field of any given planet so the atmospheres around planets would exist still but they might become more air saturated. The other thing to consider is that since this air would be so far away from the gravitational fields of many planets that it would actually get pulled into the sun over time, increasing the mass of the Sun and further accelerating the collapse of the solar system. By how much I could not tell you, but eventually the extra mass being dumped into the vacuum of space around our solar system would increase the mass of our star.
