Does Sound Travel In Space

Sound can t be carried in the empty vacuum of space because sound waves need a medium to vibrate through such as air or water.

Does sound travel in space. So in order for sound to travel there has to be something with molecules for it to travel through. Because sound is just vibrating air space has no air to vibrate and therefore no sound. And if you hear the sound of a planet or spacecraft exploding in a star wars movie remember that the filmmakers are taking liberties. Now yes space is a virtual vacuum.

That s because sound doesn t move through a vacuum and everyone knows that space is a vacuum. If you are sitting in a space ship and another space ship explodes you would hear nothing. There might not be any air in space but nasa scientist and astronaut don pettit has come up with a way of showing how waves act in microgravity. In the absence of pressure there can be no.

On earth sound travels to your ears by vibrating air molecules. He s currently aboard the international space. Sound is pressure waves that is propagating changes in pressure. You ve heard it before.

In deep space the large empty areas between stars and planets there are no molecules to vibrate. Sound travels in waves like light or heat does but unlike them sound travels by making molecules vibrate. There s no medium in the vacuum of space itself that transmits sound waves. In space no one can hear you scream.

And it is true in empty space. The vacuum of outer space has essentially zero air. For a short amount of time after the big bang about 760 000 years the universe was dense enough for normal sounds to pass through it. Now you ve probably heard that there s no sound in space but technically that s not true.

The thing is that s not completely. It would be too low or too high for our ears to perceive. Until recently we thought that since there is no air in space that no sound could travel and that is still true but only up to a point. Exploding bombs crashing asteroids supernovas and burning planets would similarly be silent in space.

Back on our own planet the sounds of very strong earthquakes are sometimes intense enough to make it out into space and infrasound can carry on going where normal sound has to pull up. However sound does exist in the form of electromagnetic vibrations that pulsate in similar wavelengths. Sound does not travel at all in space. There is a chance that sound waves can move through and compress clouds of gas and dust but we wouldn t be able to hear that sound.

It is often said that sound doesn t travel in space. For sound to travel there has to be something with molecules.
