How Hot Would a Light Saber Really Be?

Posted by ryuzaki0 on from the whizzz-vroom dept.

Datagod asks: "Has anyone ever calculated the temperature you would need to be able to slice through steel like it was thin air? How hot would a light saber really need to be? Also, I am assuming that at least some of the metal would be vaporized and the expanding gas would fling bits of molten metal at the saber wielder. Wouldn't your average Jedi be horribly scarred from all this."

    A real Jedi would jusst use the force to repel any bits away from him!

  2. Light sabers are not hot by tuxlove · · Score: 5, Insightful

    Light sabers work at the subatomic level, disintegrating matter. However, heat is generated within resistant materials, giving the impression that the sabers themselves are actually hot. Don't the slashdot guys know this?

  3. How hot? enough to burn the user? by Bananatree3 · · Score: 4, Insightful

    Looking at this comment I found, the author makes a good arguement: If the light sabre were hot enough to easily melt stuff, wouldn't it radiate so much heat that it would burn the user?

    Dunno about you, but I've never seen "steel" on my periodic table. Maybe I have the unpatched version...

    It's all good, today is not a good day to have mod points anyways, I guess.

    Seeing how the grand-parent got modded, I conclude that I hardly understand any logic in the modders mind anyways. Instead of considering using quasars for encryption, they should rather consider using /. mods.

    Sure. No one said Jedis were omnipotent


    I'm going off topic, but I think today's as good a day as any to do so... is it possible that at some point God renounced his omnipotence? As an omnipotent being, he would certainly have the power to do so... but of course he might not be able to undo it afterward, being no longer omnipotent. Perhaps he painted himself into a corner that way.


    It would certainly explain the steep decline in the quality of miracles these days...
