¿Por qué no hay sonido en el espacio?

The video explains that sound cannot be heard in space because it is a vacuum, lacking the molecules needed for sound waves to travel. On Earth, sound travels through air molecules, and it can also move through liquids and solids. In space, the absence of a medium means sound waves cannot propagate, so no one can hear you scream.
