Why do sound waves travel fastest through solids?

Back

In solids, the atoms (particles) are closest together, which allows the vibrations to travel rapidly from one to another through the object.

Why can't sound travel through outer space?

Back

There is almost no matter in outer space, so the vibrations have no way to travel through the atmosphere. There is nothing to carry the sound waves through space.
