Sound needs a medium of particles to push — air, water, or solid. The near-vacuum between planets has too few molecules for audible waves to carry a scream or a soundtrack.
Movies that boom in space are dramatic license. Real spacecraft “hear” with instruments that detect radio, plasma waves, or vibration through their own hulls.
Silence out there is a physics fact, not poetry alone. Where density drops, mechanical waves fade; light and radio keep the conversation instead.
