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?

    Apparently this would have about five times the mass of “Scary Barbie”.

    AT 2021lwx (also known as ZTF20abrbeie or “Scary Barbie”[2]) is the most energetic non-quasar optical transient astronomical event ever observed, with a peak luminosity of 7 × 1045 erg per second (erg s−1) and a total radiated energy between 9.7 × 1052 erg to 1.5 × 1053 erg over three years.[2][1] Despite being lauded as the largest explosion ever, GRB 221009A was both more energetic and brighter. It was first identified in imagery obtained on 13 April 2021 by the Zwicky Transient Facility (ZTF) astronomical survey[3] and is believed to be due to the accretion of matter into a super massive black hole (SMBH) heavier than one hundred million solar masses (M☉).

    Subrayan et al. originally interpreted it to be a tidal disruption event between an SMBH (~108 M☉) and a massive star (~14 M☉).[2] Wiseman et al. disfavor this interpretation, and instead believe the most likely scenario is “the sudden accretion of a large amount of gas, potentially a giant molecular cloud”[1] (~1,000 M☉),[6] onto an SMBH (>108 M☉).[1][7]

    The inferred mass of the SMBH, based on the light to mass ratio, is about 1 hundred million - 1 billion solar masses, given the observed brightness. However, the theoretical limit for an accreting super massive black hole is 1 hundred million solar masses. Given the best understood model of accreting SMBH’s, this even may be the most massive SMBH to possibly accrete matter.[

    So assuming that the gas composition isn’t a factor here, I’d guess that we’d probably wind up turning ourselves into the largest explosion that humanity has ever observed in the universe.

      With front-row seats.
