    Hi ShaunM,
    I’ve never been very clear on how lightsabers work. Somehow they have found a way to concentrate light into a sword by making it bounce back and forward like a laser against a mirror, only without a mirror. Also, somehow, the light has become physical enough to bang into other light like a sword would instead of passing through each other like the beams of light from two torches would.
    I guess what I’m saying is I don’t think so but I am not an engineer so don’t quote me on it 🙂

    Hi Shaunm,

    I am with James on this.

    The problem with a laser, as i guess that is what a light saber is, is stopping it at only a couple of feet rather than going off into infinity.

    Then there are other issues.

    However, this is based on the assumption that this is what a light saber is. Maybe it is something completely different, like plasma, held in place by magnetic fields… and movie magic

    the hypothetical lightsabers in Star Wars use colour and power crystals and since they don’t exist (well there are coloured crystals but no power crystals) we cannot actually make a lightsaber but we can create coloured light that can appear to stop because they don’t produce enough light to be seen but that would be quite a large lightsaber it would look like a lightsaber torch

    Hypothetical is not the right word.
