Reply to comment by AxialGem in In the universe, sound is as rare as liquid water by [deleted]

Since most planets don’t have an atmosphere, no sound would travel unless the sound originated on the surface or within the planet. And the sound wouldn’t leave the surface of the planet. So I guess if you put your ear directly on the planet and somehow managed to keep the air in your ear there, you could hear the sounds, but most likely you’d die because you wouldn’t be wearing a helmet and since there’s no atmosphere there is also no air and you would suffocate and this got really off topic and I need to get medicated.

I wouldn't be too sure about that, even in our own solar system that's not true.
Jupiter, Neptune, Saturn, Uranus, Venus, Earth, Mars all have atmospheres. Only Mercury really has very little

And it does. NASA's InSight lander is specifically designed to study seismic waves on Mars for example. Also, if a planet has an atmosphere, it has winds ofc

Regardless, sound waves still exist if you can't personally hear them, I think that's the main point
