because sound needs to travel through a medium , like air . much of outer space is a vacuum, with nothing there , so sound has nothing to travel through . Light does not need a medium to travel through .


I hope that's help !

Usually, sound needs a medium to travel through, like a vacuum for example.

Light does not need a medium to travel, and since air is considered a medium, light is not dependent on that.

On the other hand, sound needs a medium to travel through, and outer space doesn't contain space, therefore, no sound.
