Why does sound exist if it is absent in space?
I'm aware that the atmosphere acts as a conductor for sound but why is it so conspicuously absent?
I really don't understand that. In the void of space there are a ton of particles originally just hydrogen and helium that started piling up together.
How do those clumps of rock and dust combining together allow sounds to exist
Can sounds be heard inside a planet or a star or around a black hole? How and why it exists if space doesn't allow it to travel confuses me.
