Because there is a near-vaccum in space, and sound needs particles and molecules in order to travel. That's the medium in which sound travels.

There is no medium for the sound to travel. Like on the Earth the medium is air and under water it would be water. In space there is nothing so the waves can't move.

Sound waves are mechanical waves, meaning they need a medium to travel through, like air or water for example. Outer space is vacuum so sound waves have no medium to travel through.

The easy answer is that space is a vacuum and can't transmit sound because there is nothing there. As with a lot of science, the easy answer isn't quite true.
Space is not a perfect vacuum, it's a very very thin gas, and it does transmit "sound" just like any gas. The gas is so thin, though, that it takes an area in space larger than the earth is wide to transmit as much energy as you put in a whisper. The speed of sound in interstellar space is a very important factor in determining how stars form.

Sound waves require a solid medium or gas to travel through.
Space, as such has very little matter to support the existence of sound waves.

THERE IS NO AIR IN EMPTY SPACE!
PLEASE read this passage CAREFULLY
AND try to UNDERSTAND that "SOUND WAVES" and "LIGHT WAVES" are DIFFERENT.
---The main reason is: in empty space, there is NO AIR.
What we call "sound" is actually VIBRATIONS in the air.
Now, there are indeed light waves and radio waves in space, but these waves are not sound, but light. Light does not need air to travel, but then you don't hear it; you see it, or it is interpreted by your radio set and then translated into sound.
Astronauts in space do talk to each other because in the spacecraft, there is plenty of air, so they just talk normally.
When they are spacewalking, they talk by means of radios in their helmets.
The radio waves, again, have no problem in space, but they're not sound. They're radio, which has to be converted into sound by the astronauts' headsets.

Sound is caused by particles of air that are caused to vibrate. There are no particles of air in space, so therefore there is nothing to vibrate and pass on the "sound".
This is a very basic explanation, but it sums it up.

because space is like a vacuum that sucks everything away. Sound won't travel in a vacuum either.

honestly sound would not shuttle in outer area. Sound is mechanical waves, i.e. it demands a fabric medium to shuttle. Becaue the outer area is a vacuum, as a result sound would not shuttle in outer area. despite if, a no longer user-friendly question pal!

sound needs air to vibrate through... no air in space
