It's no secret that George Lucas doesn't give a hoot about physics, but just for the heck of it here is another issue I have with the film series. The films frequently feature intense laser fights both in outer space and on land, but what doesn't make sense is why the lasers are visible. Given that lasers would have to be highly energized beams of light to do so much damage, they should not be visible unless refracted. Those of you who remember Mr. Powlin's green laser pointer will no doubt remember that the light could not be seen until it hit the wall or was shown through chalk dust. Therefore, unless space is secretly filled with chalk dust, the lasers should be invisible. But invisible lasers would be so much less entertaining, so perhaps just this once we can overlook such crimes against science. Just this once.
