Because there are no enough molecules in empty space for sound to be propagated.

Which do not travel through empty space?
sound cannot travel through empty space.
What type of waves travel through space?
Sound waves cannot travel through space.
What type of wave can't travel through space?
Sound waves cannot travel through space.
How do you hear yourself in space without a space suit?
Sound cannot travel in empty space. But, sound may be able to travel through your body.
Why can sound waves not travel through empty spuce?
Sound waves cannot travel through an empty space because an empty space is usually a vacuum.
What can't sound travel through and why?
Sound cannot travel through a vacuum, such as in outer space. "Sound" refers to waves of compression which travel through matter. When there is no matter, there can be no such waves, and therefore no sound.
What is it that sound cannot travel through?
Sound can travel through any medium. If you remove the medium you would end up with a vacuum. It is in vacuums that sound cannot travel as it needs a medium to travel (it travels as a compression wave or shear wave). Space is almost a perfect vacuum so sound is unable to travel through space.
Where can sounds not travel?
Sound cannot travel in a vacuum. Sound is mechanical energy, and it travels by the transfer of mechanical energy through the medium through which it is traveling. If there is nothing to transfer the mechanical energy, like there is nothing in a vacuum, sound cannot travel there.
Does light need a medium through which to travel?
No, it does not. It can travel through any open space. Sound, unlike light, needs a medium to travel. So light can travel through outer space but sound cannot because there is no medium.
Why is visible light considered to be radiant energy and can travel through empty space but sound waves cannot travel through a vacuum?
Well light is an electromagnetic wave and it pushes itself through space ,but sound requires particles to travel through and if there are no particles for it to travel through you have no sound
Does sound travel outside the earths atmosphere in space?
No. Sound is simply vibrations of particles that travel in a sort of "wave" motion. Since there is no medium (particles of matter) in space, it is not possible for there to be sound.Sound waves require a medium to travel through. They travel by knocking particles into other particles, causing a vibration to be transmitted.As outer-space is a vacuum, there is no matter present; this means that there is no medium for sound waves to travel through. Therefore, sound cannot travel in space.
Why cant you hear one one another in space in space?
Sound needs something to travel through. That's usually air on Earth. Space is a vacuum - therefore, sound cannot travel through it.
