Most people know that when you see lightning, the sound of the thunder comes later. You can find out how far away it is by counting the seconds. You can do the same thing with fireworks displays. So, if the sound of lightning comes later than the light from the lightning, that means the sound of the explosion will come after you see it. Fire in space.
Fire requires air and there is no air in space.
The only time you get a fire in space is if you put together all of the components consumed in the fire. You couldn't light a match, because it needs oxygen. But, you could fire the rocket engines because the fuel provides everything needed. If a spaceship crashes into something, there would be no burning wreakage.
