One of my qualifications for a great sci-fi movie is that the story has to be good enough that you do not think about things like the physics of space battles. As soon as you start wondering about the details of how they could do that in real life, the entertainment we derive from the movie is over. I purposely avoid this pitfall and promise myself to puzzle over the details after the movie is over. Here is a great resource on the physics of space battles. It also poses more questions than it answers. If sci-fi movies and video games are not good examples of space battles then our knowledge of space battles is more limited than we think. How are we going to break this rut in thinking if the physics of actual space battles is not dramatic enough for movies and video games? With this limited public knowledge how could we sway public opinion if we needed to fight a real space battle?
