When a fission or fusion explosion occurs on Earth, it generates a shockwave that is pretty formidable. I would think that an explosion in space, such as a nova or an exploding sattelite, should also generate a shockwave. But will it actually do it? The reason I am suspicious is that on Earth there are a lot of mediums (such as air, water and ground) that shockwaves can be carried on. There are no such mediums in space. So if a shockwave does occur, what carries it? At what speed would the shockwave be carried (I am assuming that it will not be faster than c, the speed of light)? All of the stellar explosions we've seen are both distant and far in the past -- the most recently acclaimed supernova took place twelve billion years ago, twelve billion light-years away. A shockwave didn't carry that far or that long.
