How Lethal Lightsaber Can Be?

Research is a very unpredictable process. Sometimes you just end up making really great discoveries that actually you didn’t see coming your way. I recently uncovered a fundamental property of the metal star wars lightsaber, which is an awesome weapon from Star Wars, while doing my regular plasma physics research. I found that, while it is in theory possible to build the powerful lightsaber, it’s likely it would be the most dangerous weapon ever created in history for perpetrators and victims.

Despite the name, it has been established that in the movie Star War these ancient weapons of Jedi are in fact, not actually a metal star wars lightsaber but are blades of plasma. Plasma is often known as the fourth state of matter, besides solid, liquid, and gas is the first three. However, plasmas are by far the most common state of all visible matter in the universe. The thing that makes plasma different from the other states is that is composed of electrically charged particles, loose electrons, and atoms that have lost electrons, despite having no overall charge which is used in star wars Darth Vader lightsaber. Any moving electric charge, such as those inside the plasma, creates magnetic fields and can also be manipulated using magnetic or electric fields, unlike a neutral gas.

Magnetic fields are the key to containing the plasma in a blade; they can counteract the pressure of the hot plasma trying to expand into its surroundings. This is exactly one of the approaches that have been developed in trying to harness nuclear fusion power, in which atomic nuclei as atoms that have no electrons, collide to form a new nucleus while releasing huge amounts of energy. Fusion requires incredible temperatures so that the positively charged atomic nuclei can overcome their tendency to repel each other. We create these hot plasmas in star wars Darth Vader lightsaber fusion reactors use strong electromagnets in the reactor walls to keep this plasma at bay.
