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?
most everything in the milky way galaxy is orbiting the center of the galaxy clockwise relative to our north*, so we’d probably enter the gas cloud from the side by drifting into it faster than it is moving
*that’s orbital north, the direction that’s perpendicular to orbit and close-ish to the magnetic north pole (which is tilted relative to the orbit)
