Lightsaber is an elegant weapon in the “Star Wars” universe. It was a brand weapon the Jedi, it is a glowing blade that maintained the peace for the millennium in the Galactic Republic. The weapon was first seen in 1977 in the first “Star Wars” film debut. The epic fight between Obi Wan Kenobi and Darth Vader started it all, of course with the signature hum.
Although, Lucas Films owner, George Lucas wouldn’t want to “Star Wars” to be remembered as a science fiction, this article will study how science could build the lightsaber. The six episodes of the “Star Wars” films, (of course including “The Force Awakens”) featured the lightsaber as four feet glowing blades. They definitely has a vast amount of energy and can melt large amount of metal quickly. This implies that these weapons should have a compact and powerful energy supply. Lightsaber can cut through flesh easily, though their hits could not burn the hand of the bearer.
A couple of lightsabers will not pass through each other, and there are various colors that scintillate blades. Here is a more realistic technology that possibly could make the lightsaber in real life, it is called plasma. It is a king of material made by atoms of stripping gas and electrons, this process is called ionization. The stripping makes a material glow. Plasma comes after the three states of matter, solid, liquid and gas, which makes it as the fourth state of matter. We may have seen all sorts of plasma, like the fluorescent light and the neon lights. The lightsabers are not really ultrahot plasma tubes, it is like a hot gas which cools and expands, which is also like a usual fire which is always plasma, more of an unfinished one. So if a lightsaber is a plasma based technology, it needs to be contained properly.
