Light is almost a million times faster than sound (in air), which is why you get a delay between seeing lightning and hearing thunder (unless you're VERY unlucky). The farther away the thing is, the longer the delay between the sight and sound
So it's probably for the best that sound can't travel in space because just think how confusing it would be to watch space battles 🚀⚡️👾 with all the explosion noises totally out of sync
