Sound waves cannot travel through:

  1. Solid
  2. Liquid
  3. Gas
  4. Vacuum

Answer: Vacuum

Sound requires a medium (solid, liquid, or gas) to propagate as mechanical waves. In vacuum, there are no particles to vibrate, so sound cannot travel. This explains why space is silent. [[NCERT Physics Class 9]]
