Because there are no enough molecules in empty space for sound to be propagated.
Sound waves cannot travel through space.
Sound requires a medium, such as air, water, or solid surfaces, to travel through. In outer space, there is no medium for sound waves to travel through, so sound cannot propagate in the vacuum of space.
Sound requires a medium, such as air or water, to travel through. In the absence of a medium, such as in empty space, there are no particles for sound waves to propagate through, so sound cannot travel.
Sound cannot travel in empty space. But, sound may be able to travel through your body.
The question is irrelevant, since sounds cannot be transmitted through space.
Sound requires a medium, such as air, water, or a solid substance, to travel through. In an empty space, there are no particles for sound waves to travel through, so they cannot propagate.
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.
Sound waves do not travel through empty space because they require a medium, such as air, water, or a solid, to propagate. Similarly, mechanical waves like seismic waves also need a medium to travel and cannot propagate through empty space.
No sound can travel through space. Sound travels by vibrating adjacent molecules. The sound wave travels along these molecules until it dissipates with distance. In the vacuum of space, there are no molecules (this is not considering celestial bodies like planets or meteors because they are not a part of the vacuum), so sound cannot travel.
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.
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.
We can't speak or hear in space because there is no air the sound can travel through.
