Why does sound not travel in space?

Why does sound not travel in space?

Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.

Why is space completely silent?

In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. Space is usually regarded as being completely empty.

What happens if u breathe in space?

The vacuum of space will pull the air from your body. Without air in your lungs, blood will stop sending oxygen to your brain. You’ll pass out after about 15 seconds. 90 seconds after exposure, you’ll die from asphyxiation.

Why is it impossible to hear sound in space?

No one can hear in space, the reason for this is because there needs to be air movement like wind for example to create a longitudinal wave, and since there is no air in space, it is impossible for sound to exist there, unless they have radios to communicate to one another in spacesuits or spacecrafts.

Why can no one hear you scream in space?

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.

Why do sound waves not travel in space?

Sound cannot travel in space due to the lack of pressurized molecules in the vacuum. Sound waves usually travel through air or water, but they can also travel through solids too, like walls or furniture.

Why can light travel through space, but not sound?

Sound is a mechanical wave and requires a medium to travel in. If there are no molecules present to vibrate and propagate the energy, sound cannot be heard, which is why sound cannot be heard in outer space. It is because light can travel through space that we can see the sun, moon and stars.
