Are Jedi light sabers theoretically possible?

Question

What would their reality entail?

Answer 1

I guess you could do it with laser light, but the device would be fragile. You'd need a mirror on the far end of the thing to hold the beam in. And the amount of power you'd need to do some of the stuff they do with lightsabers.... You'd lose a lot of the energy from scattering dust in the path of the beam.

And you'd need a speaker or something to make the cool lightsaber noise.

Factoid--some of the actors in the new SW trilogy had a hard time keeping from making the wawa lightsaber noises (with their mouths) during the fight scenes, because they (like everyone) had done lightsaber fights so often as a kid. They had to be bludgeoned to make them believe that the required sounds were added post-production.

Answer 2

You would do well to separate science fact from science fiction. SciFi uses all sorts of unlikely devices that have no basis in physics or any other genre of science.

If the Jedi sabers are in fact light, then there is nothing I know of to foreshorten the length of the sabers...as shown in the movies...and still contain the kind of energy they exhibit And that's the rub. Lockheed Martin and Boeing are developing an airborne laser light weapon, but the beam goes on for a very long distance, its energy is dissapated mainly by refraction and reflection due to particles in the atmosphere (e.g., clouds and dust).

In general, scifi tools and weapons overlook the need for the inordinate energy to power them. Our universe has just so much usable energy available. Some of the scifi devices require energy way in excess of what is available in the whole universe. But, hey, these devices make for great special effects.

Answer 3

It's mentioned in the books and throughout Star Wars "Lore", is that the energy being produced is cyclical, like a chainsaw, and does not terminate at a specific end point. Of course, I don't know exactly how it works, but somebody mentioned earlier that it's "light", which it's not. A lightsaber blade is energy focussed in a way that we've yet to really figure out for ourselves.
Imagine how hard it would have been to explain to the people thousands of years ago that the world was round, not flat. Their response? "Well, if it wasn't flat, then we'd just fall off", or something like that.
We'll figure it out someday, but just keep in mind, it's cyclical. The best mental image I can come up with is a chainsaw; the edges just keep going around and around.
So, theoretically, it is possible

Answer 4

I can't see how anything would get a beam of (laser) light to terminate a specific distance from the handle, a beam of light would propagate in one direction forever until it hit something. Star Wars always shows the saber's beams stopping each other when they cross like they are solid, this is not possible with a beam of light either. Even if it were, I also don't think a power source that powerful currently exists that would fit into a flashlight size handle either.

Answer 5

Nuclear Heat Projections

Answer 6

A Jedi could have a mild sabre 10ft long yet while he can no longer hit the ventilation shaft thingyin the folds of the dying megastar's floor then the insurrection is purely no longer happy in any respect and that's purely no solid. extremely i think of they provide the longer mild sabres to the Jedis with short palms. The stress can no longer do each thing.

Answer 7

I can see it happening.. maybe not with light tho.. so i guess it can't be called a 'light' saber.. maybe plasma contained with magnetic fields... (it'll make sounds too!) who knows ;)

Answer 8

i know a guy who works on high powered lasers and stuff. He said it is possible, except there is (cuurently) no way to contain the beam. it would just shoot out forever. There is no way to controll how long it extends.

Answer 9

you can search light sabers on howstuffworks.com
they explain how these wonderful things work

Answer 10

I presume so in that far distant future as they
have also conquered faster than light travel.
