What would happen if you put a mirror in the lightsaber beam? being light it would reflect...correct?

A lot of comments below, someone said that the lightsaber released energy on the air as well. That is completely true, and actually, it is what causes the lightsaber sounds, because produces vibrations on the blade. It is mentioned on some Star Wars book... which one was it? I'll post again when I remember the name.

I just finished reading I, Jedi for the first time yesterday. Great book.

Anyway: in said book, Corran Horn describes in some detail the components of a lightsaber. I was very interested at the mention of a 'magnetic ring' around the point where the blade comes out. Apparently this ring gives off a strong positive charge towards the blade, which is balanced by the blade's strong negative charge. This would imply that the blade is created (like just about everything in RL :P) by the movement of electrons. This covers Acey's point well enough for me.

Also, it would appear that the only component of a lightsaber not available IRL, besides the crystal, is an appropriate power source. The battery needs to give off huge amounts of a type of energy not totally but almost completely unlike electricity. :/

I see what ur saying Tarp. Would have to be a containable magnetic field or one way. But if it's strong enough, it forces the energy in so tight, the blade if formed...hmmmmm yeah that sounds cool!:D

No, it's definitely not fusion, or any kind of nuclear or chemical reaction. As far as I understand, pretty much how it works is that a power source far more advanced than any of ours spits out some form of energy, which is focused by the crystals into the coherent beam we know and love. A magnetic field to contain the vast amount of energy makes sense, and would explain things like saber locks and blaster bolt deflection. JavaGuy made a very well thought out post a while ago - I'll see if I can find it.

EDIT: Ah, here we go. :)

Good topic.

Um, guys, "pure energy" is a meaningless concept. Everything in the universe...well, everything that we can physically interact with, even if only indirectly...is energy.

I can buy that the blade is magnetically manipulated plasma, but a physicist friend of mine has suggested other possible solutions. There are wave forms that have great amplitude for a short distance but then very abruptly begin to attenuate rapidly after a certain number of cycles. It's possible that the lightsabre is extremely high energy EM radiation traveling in such waves.

What doesn't wash about the plasma idea is that the magnetic field would be so extraordinarily powerful that we would see other very obvious effects of it that I see no evidence of in the movies. On the other hand, it could possibly explain the whole concept of lightsabre dueling: If the blades were like laser beams, one could pass right through another uninhibited, but magnetic fields, depending on their structure, might repel each other with greater force than human strength could overcome, so one "blade" could indeed block another. That could also explain sabre lock, if the magnetic fields come together lined up just right.

And Java, if you say *anything* about taking things out of context, I'll hunt you down and shoot you with your own bowcaster. :P

I think it produces heat from the density of the object that its touching it (which explains the air thing) which is really the only possiblity thats whyt it appears like the door is melting in Ep 1 (because it is) but in air only little heat is produced or something...... dunno just a theory must be a few leapholes in the creation of the Lightsaber.

I dunno if what I'm going to say is stupid, but perhaps the blade is like the sun. What prevents the sun from literally blowing apart is the core. Perhaps the core has some odd magnetic attraction (The Force), and that's what keep the energy intact. The energy MUST react with the air molecules, but this energy is probably replaced by the crystal's energy.

I don't know if it makes sense, it's just a vague guess. SNC 1D1 doesn't teach much in ways of energy.

that's true...if heat is produced only when the energy (I'll call it fusion for now) is in contact with something else, then wouldn't logic and physics dictate that energy is transferred to the air molecules around the blade? Thus, heat is created, or at least a reaction in which the energy transfer will produce heat will take place.

As to the nature of the blade of the lightsaber, I kinda agree with the notion that it may be fusion energy controlled with a magnetic field. I like the fusion idea because I really do not believe that the lightsaber's power is recycled by returning the energy to the hilt (the power unit), then back to the blade. A form of fusion would be much more viable and practical, in that it renews itself, and contributes to its own creation of energy. The only problem would be to actually initiate the fusion reaction, and how to control it. The phrase of "igniting" a lightsaber kinda fits in with this theory, and so does the magnetic field being used to control the blade.

However, being that I'm NOT a physics major, I still can't see how the hilt can produce such a powerful magnetic field (containment, whatever) to harness something as powerful as a fusion reaction without getting impractically bulky as well. Maybe technology...?

well that's my bit, sorry about all the long-winded stuff...can you tell i'm studying to be an engineer?

Not a heck of a lot. And that does cause the saber to always have a bit of heat around it. Don't forget the 1337 rain-hitting-saber effects on yavin_swamp in JK2, either. :)

A Lightsaber definitely does not produce heat while its not in contact with anything but when it comes into contact with anything the raw energy is passed to that object as heat (called radiation). Raw energy does not exist as far as I am concerned which is why Star Wars is science fiction And people are right it only uuses up energy in its "battery" when it touches and therefore cuts through something because the energy is being passwed to that object normally it just reuses the energywhich again I think is physically impossible because when you use energy it just changes to another state of energy. e.g. candle wick is chemical energy you light the candle and the energy converts to heat energy heating the air molecules around it.

I think that's right feel free to question me I'm slightly dumb at the best of times >.<



Hmm, I can't quite tell, if I have convinced myself of this or not, but isnt it always touching "something"?

I mean there is matter floating around in out "air" that we dont see.

So wouldn't it being having an effect on that?

A light beam never stops unless something is put in its way. So why do the light sabers end? Why because its not really light its a crystal with energy passing through it.

It's already hard enough to deflect the concussion shots from those supertroopers with Force Push. :cool: On Taspir, I had to be half a bridge away to deflect the shot. Oh well, duels aren't ALL reflexes. I average 0.203 on reaction time, which is pretty good, and I still can't believe how fast these NPC's can block concussion shots.

that's a good way to train as well, I'd like to point out :)
Fight npc's (and a lot of it) in timescale 0.5, and do it often, you'll see your reflexes actually increase ... :)

One theory i have heard of holding such energy in a certain location (in correspondance with the object that generates the energy) is a magnetic field.

First I think we need to think about the name:

Lightsaber

Light and saber together conjure an image of a sword whos blade is made of light. By golly thats what it looks like!! Alas that is not what it is.

The blade, although it does cast light, is not made of light. It is made of energy. When we think of energy 9 times out of 10 we think electricity. So lets look at Electricity as our energy comparison.

Does electricity reflect off of mirrors?

The energy within the lightsaber hilt is tremendous and the careful engineering of the device harnesses this energy. Activation/ignition allow the energy to emit from the end. The method of determining blade length escapes me right now but it isn't germaine to the topic anywho! If this energy is strong enought to cut steel/metal it would absolutely devestate even the most highly polished surface.
