Light waves cannot travel through the vacuum of space.

The correct response is:
Matter is needed to transmit sound waves.
In space, which is a near vacuum, there is not enough matter (air or any other medium) to carry sound waves, so explosions would be silent in space, even if they were visually spectacular. Light waves, on the other hand, can travel through the vacuum of space, so the visual aspect of explosions would still be visible.
