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?
Gradually gliding into a gaseous cloud that the sun lights up would be genuinely fascinating, but still probably kill everyone. Pros and cons.
… would it affect the northern hemisphere first? I have no idea which direction the solar system actually proceeds.
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)
