问题       Modern science fiction movies are often known for their breathtaking special
Line  effects. These effects can show us a glimpse of the future, and frequently have
      tremendous dramatic force. Sometimes, however, special effects can leave the
      science behind to focus only on the fiction. One of the worst offenders is a film’s
(5)   depiction of explosions in outer space.
            On the Earth, explosions occur in some form of matter, usually air or water.
      The change in energy level in the matter creates the energy differential known as
      a shock wave. The wave is what creates the characteristic "boom" of an explosion.
      Since there is very little matter in outer space, the energy transfer never takes
(10)  place. Consequently, there is no sound. Further, because air and water are not
      perfect conduits for energy, they measurably slow the travel of the explosive
      force. This allows the explosion to unfold in relatively slow motion, which
      renders it visible to the eye. In space, there is nothing to slow the energy, which
      would disperse almost immediately. The effect for an observer would be a bright
(15)  flash, gone almost as soon as it appeared, and nothing like the great billowing
      space clouds shown in the movies, suggesting that reality is insufficiently
      dramatic for cinematic representation. [br] OBTUSE:
