Zinnia, you've poked one of my pet peeves. No, anything cannot happen in a story. Less than in reality, actually, because reality doesn't have to be believable. Hence the phrase, truth is stranger than fiction. I have to agree that science fiction that worries too much about "known laws" and all that stuff gets boring. However, sometimes nonsense is both unnecessary and damaging, and then it really annoys me. That's not the case here, but take the example of Star Trek. Millions of people watch, lots of kids learn from it. So why have Dr. Crusher spout drivel like, "My God! The DNA is falling apart into amino acids!" In the context of the story, that's just technobabble, so why not have the *right* technobabble? Paramount has a big enough budget to ask a high school biology teacher what to say. (End of rant.)
