This probably sounds like a dumb question but I would really appreciate some help! I am very very interested in space but I don’t understand complex topics very well because of my learning disability. When I tried to google this I really couldn’t understand the explanations 🙁 thank you if anyone responds, I really appreciate it!!
Edit: thank you all for responding so helpfully and so quickly, its so nice to not be talked down to for not understanding things

So in our normal air there are many particles. These particles get moved if you for example open your mouth and say something. Like moving your hand through water and small waves expand. So the particles basically hit each other and create soundwaves. These soundwaves can be detected and uncoded by your ear. But a vacuum has little to none particles and if your voice try’s to move them only a few or even non get pushed. So the lack of many particles makes it for the particles impossible to hit each other and create the „wace“. The spaceship basically mimics the earth because there is air. And then the particles can hit again.
