Does Sound Travel In Space

You ve heard it before.

Does sound travel in space. It would be too low or too high for our ears to perceive. Sound travels in waves like light or heat does but unlike them sound travels by making molecules vibrate. 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.

Now yes space is a virtual vacuum. 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. Chances are you wouldn t hear much of.

Sound travels in waves just like light or heat does but unlike in those mediums sound travels in space by making molecules vibrate. 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. 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.

Now you ve probably heard that there s no sound in space but technically that s not true. 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. There s no medium in the vacuum of space itself that transmits sound waves.

If you are sitting in a space ship and another space ship explodes you would hear nothing. In the absence of pressure there can be no. Sound does not travel at all in space.

On earth sound travels to your ears by vibrating air molecules. He s currently aboard the international 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.
