#plasma $XPL Plasma is the fourth state of matter, making up 99% of the visible universe. It's a superheated gas where electrons are stripped from atoms, creating a soup of ions and electrons. Plasma is found in stars, lightning, and even neon signs. On Earth, it's relatively rare, but scientists are working on harnessing its power for fusion energy. Plasma's unique properties make it useful for various applications, including medical treatments and space propulsion @Plasma
