How could you create a lightsaber like the ones in Star Wars?

Answer 1

It hasn't been done...yet. But in the sci-fi terms that define what a lightsaber is constructed of, it wouldn't work. But even George Lucas himself admitted that he was simply creating fiction and didn't know anything about how it would work. He just called it a lightsaber because...well...it emits light. When you go home and say "turn on the light, would ya?" are you referring to a nonstop beam of light? No, you're visually describing an incandescent bulb operated by electricity, which of course emits light. Same thing applies to a lightsaber - it emits light, but that doesn't mean it is made of light. When little Anakin told Qui Gon that he saw his laser sword, are you going to accept that as fact? Anakin was a kid when he said that, and had no knowledge of how a lightsaber was constructed, nor physics for that matter. You're gonna go off the word of a KID? If you want to build a lightsaber, you have no choice but to go with existing technology, and if it doesn't exist, well then - invent it. A plasma saber can be called a lightsaber because it would emit light. Plasma is possible here people. It occurs naturally everyday. Physicists always yammer about how you can't generate enough power to inject a plasma into a magnetic field, which bugs me because they're always talking about plasma and magnetic fields as if one has absolutely nothing to do with the other - like they should be regarded as two separate and unlinked entities. Let's talk electricity. A flow of charge generates an electromagnetic field, and vice-versa an EM field will generate a flow of charge. Now let's talk about conductivity. Your best conductors are silver and copper. These are good conductors. Some materials oppose a flow of charge - these are known as nonconductors. But, as fate would have it, nonconductors will conduct just fine if they become ionized. For example, a simple capacitor utilizes this concept. A charge builds up one one end of the capacitor, seeking to dump to the other end to complete its circuit. To accomplish this task, a nonconductor is sandwiched in between. And that's when something amazing happens. When enough charge builds up, the nonconductor becomes ionized and the capacitor is able to make its charge dump. When this occurs, the nonconductive material returns to its nonconductive state and the process starts all over again. Of course, you're thinking, how does this answer my question? We live on a giant capacitor. The clouds in the sky will gradually build up a static charge. And naturally, when enough charge builds up, you get lightning. Air is a nonconductive material until it becomes ionized. And when a material becomes ionized, this means that each atom has enough energy to excite its electrons to another level until one gets bumped off. What results is a flow of charge, a flow of electrons, charge in motion - a current, pushed by a massive voltage. This of course leads me right into plasma. What IS plasma? Plasma is simply an ionized gas. It doesn't matter what type of gas it is, as long as it IS a gas. Air is a gas, and when it becomes ionized, it is converted to plasma - this is what we call lightning. And, of course, I'll say it again - any charge in motion generates an EM field, and therefore plasmas generate their own EM fields. This is all I will say for now - that lightning (electron arcing) is the simplest way to create a plasma saber. Of course, lightning zigzags, because it follows a nonlinear path of the least resistive molecules in the air. If you use a laser in tandem to heat the molecules, this will provide a linear path of least resistance. And PLEASE remember that like polarities will always repel. If you keep it simple, simple solutions will always present themselves. This is all I will write, for if I give any more information, it simply would be no fun for you. But if you understood what I wrote and what it implies, I'm sure you can figure out the rest. The answer is YES. It is definitely possible, and it is even easy if you have the proper resources and knowledge. This answer brought to you by http://boardster.net/Lightsmith

Answer 2

Lightsabers are the weapons Jedi use. It is a butt with a deadly blade which is a laser beam. It deflects lasers and can even go through metal. The colors are blue, green, purple, and red. Evil Jedi (called Sith) uses the red saber. However, some training Jedi (mostly young children) use yellow or orange lightsabers.

To be able to master the ancient weapon you have to be skilled and interactive with the force . Its not a clumsy as a blaster and not as un predictive as a ships gun .A jedi builds his own saber .If t you kill a jedi or sith you tend to take there saber .The lightsaber was bought about in the Star Wars sagas .

Answer 3

Plasma energy passes through a focusing crystal. When the plasma passes through the crystal, it's power is intensified, allowing it to cut through most anything. That's the basic explanation. Here is a more detailed one.

A typical lightsaber hilt consists of a metal cylinder between 30-35 centimeters in length. However, the size of individual hilts varies drastically, as the weapon is tailored to it's creators specific needs and preferences. The lightsaber's mechanisms are contained within the hilt. High levels of energy generated by a high-output Diatium power cell are unleashed through a series of focusing lenses and energizers that convert the energy into plasma. The plasma is then projected through a set of focusing crystals that lends the blade it's properties and allows for the adjustment of blade length and power output. The ideal number of crystals is 3, even though only one is required.

Once focused by the crystals, the plasma is sent through a series of field energizers and modulation circuits within the emitter matrix that further focuses it, making it into a coherent beam of energy that is projected from the emitter. Blades will typically extend out to 1 meter before being arced by the blade containment field back to a negatively charged fissure ringing the emitter, where it is channeled back to the power cell by a super conductor, and thus completing the circuit.

Answer 4

You can't, only if are a jedi, other wise you will cut you'r head off. Jedis have the force with them so they can control a lightsaber, maybe you have the force to but you dont have a lightsaber so good luck.

Answer 5

With the force the Jedi/Sith can control the length, width and when it turns on and off.

There are also buttons to control those things too if they can't be bothered.

If you're talking about a real life Fx lightsaber - press the button and it lights up.

wave it around and it'll make the same sound every three movements.

Answer 6

It deflects back laser fire. It can cut through and/or melt metal due to the heat it gives off. Unless modified in a specific way, they can not work underwater. They can cut off a limb easily and the laser fries up blood vessels so a person cannot bleed out. If you just get a scratch from a lightsaber, the scar is permanent

Answer 7

Kyloias: The Jedi use the blue or green Adigan Crystals, then surround it with the Force power which makes the wires then force and lock together two small cylinders and screw on the button.

Answer 8

You hit a little button.
