Ask an Explainer
Q:
Is it true that in space no one can hear you scream?
A:
Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn't even leave their mouths.
