Today we are examining the close relationship of two facets of world building in speculative fiction, science, and magic. Both are tools our characters employ.

Science is not magic. It is logical, rooted in the realm of real theoretical physics. The writer of true science fiction must know the difference, and never “let the streams cross.”

Egon: Don’t cross the streams.

Peter: Why?

Egon: It would be bad.

Peter: I’m fuzzy on the whole good/bad thing. What do you mean “bad”?

Egon: Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light.

Magic is not an accepted trope of hard science fiction so don’t even try to justify it. If you are writing a sci-fi fantasy mix, don’t try to pass if off…
