Yes, but you could theoretically build a light saber with a thin tube coming out of the hilt ending on a large circular mirror, which would bounce the beam back to the hilt. The thin tube could even be retractable with a telescopic straw, so you'd get basically the same effect as light sabers. Also if the beam was strong enough it would cut through anything so nothing would ever reach the middle, where the structure was.Nincompoop said:Lightsabers aren't iconic because of the power, they are iconic because the beam actually cuts itself off after a certain length, which is absolutely impossible. At least when you are solely dealing with light, as in photons.
Not that it makes any sense to restrict a weapon like that.
