The article explores the idea that while space is generally considered empty, there is still some matter present that can transmit sound. It challenges the well-known tagline from the film Alien, suggesting it should be amended because sound relies on a medium to travel. The piece discusses how acoustic waves, which we perceive as sound, propagate through different materials like air and water. The scholar explains how sound waves work, emphasizing that while space is mostly a vacuum, it is not completely devoid of matter, allowing for some sound transmission under specific conditions.
In space, no one can hear you scream unless you scream loudly enough and in the right place, as there is some matter present between the stars.
What we think of as sound is really just a vibration that travels through some sort of material (a medium), whether it's air, water or solid matter.
