Lightsaber Duels Would Be Over In Seconds, Possibly Kill Everybody
Along with space battles, alien creatures, and angst-filled whining, one of the key ingredients of the Star Wars saga is the lightsaber duel. An amalgam of Samurai duels and coke-fueled disco aesthetics, the lightsaber fight is a cultural icon, as evidenced by every child who's ever whacked a sibling with a broomstick while yelling about the Force.
Or (sigh) ... four broomsticks.
While the movies portray lengthy, intense lightsaber duels, real-life lightsaber battles would probably end faster than a prom night's lovemaking. According to a sword-fighting instructor, because of the lightsaber's "incredible cutting ability and instant lethality" fights would be over almost immediately. As soon as someone made a move, they'd either be victorious or leave themselves vulnerable to being laser-sworded to death. The exciting, prolonged fights we see in the movies don't make sense because "you aren't there to injure the weapon." Think about how fast a point is scored in a fencing match. Fights would have way less frantic slashing and a lot more inaction, each fighter trying to mind-fuck their opponent into fractionally dropping their guard.
