The Slow Sound of a Scream on Mars
Bjorn Carey writes on Space.com:
In space, no one can hear you scream, the saying goes. But what about on the surface of Mars?More here.
A new computer simulation reveals just how far sound waves travel on the red planet. And if you're screaming for help, you better hope people are nearby.
Sound in air, water or any medium travels in waves that propagate as one molecule collides into the next, and so on. Because the Martian atmosphere is much thinner than Earth's, the distance between molecules is 120 times as far as in your back yard.
