noun

Definition: a substance that is similar to a gas but that can carry electricity

Plasma is considered by many to be the fifth element because of its similarity to fire, gas and in some cases, water, which is why many didn’t see it as its own individual identity until we run into it more and more and study it in detail in space. Plasma also has the unique ability to conduct and store electricity. Which is why most likely in all Sci-Fi shows they are using plasma instead of a laser due to it dispersing on impact and shocking the victim. Unlike lasers that at this point in time can not do so and also didn’t fire like a bolt.

They should help many people understand the science behind Sci-Fi better.
