First time I saw the North Lights in person I also expected something other than complete silence. I don't know what, but they're so surreal and massive I thought you'd hear something.
imagine ... hearing the jackhammer scream of our star
Sounds are a form of energy. If we were bombarded by sound waves for the entire existence of the planet, I assume life would have adapted to harness this abundant power source and made it instrumental to how we survive and thrive.
You wouldn't, of course. Hearing, the way we hear, in such an environment would be useless. We wouldn't have evolved that. This is like saying "ultraviolet radiation from the sun would be everywhere, all the time, can you imagine?" It is everywhere all the time, but as such it isn't a useful sense to possess, so we don't.
This also makes some very weird assumptions about what the sound would be like. If space were a medium sound could travel through then it would--like all mediums capable of carrying a sound wave--alter the wave in many ways. Intensity, frequency, etc. But since we don't know what kind of medium that would be, and since the comment doesn't posit any particular medium, we don't know what the sound would sound like or even how loud it would be.
A bullet fired from a gun goes more or less at Mach 1, correct?
It's thirteen years to the sun at the speed of a bullet?
Spacecraft towards Mercury, or the Parker Solar Probe go much faster than that, take a few years to make it there, but they are doing so picking up speed in flybys of first Earth, then Venus, then Mercury, in several, ever tighter orbits.
It's both fun and illuminating to try and visualize these things in new ways. In this case, from the viewpoint of a bullet.
I guess the sun being loud shouldn't really be all that strange; if I recall correctly the sun has explosions happening on it everywhere all the time, the strange part though is the whole sound lasting for thirteen years part.
