Question

why can you not hear sound in space? space is a mop and has no molecules. space is a vacuum and has no molecules. space has too many molecules. you can hear sound in space.

Explanation:

Sound requires a medium (made of molecules) to travel through, as it propagates via vibrating particles. Outer space is a near-vacuum, meaning it has almost no molecules to transmit sound waves. The other options are incorrect: "mop" is a typo/error, space does not have excess molecules, and sound cannot be heard in space.

Answer:

Space is a vacuum and has no molecules.
