What Is Plasma? The Fourth State of Matter
Plasma is often described as the fourth state of matter, but it’s actually the most abundant form of matter in the universe. When gas becomes super-energized, its atoms split into charged particles, creating plasma. This state conducts electricity, responds to magnetic fields, and emits light. From stars to neon lights, plasma surrounds us more than we realize. Its scientific and industrial uses continue to grow as technology improves.
Why Plasma Dominates the Universe
Although solids and liquids feel more familiar, plasma makes up more than 99% of visible matter in the universe. Stars, nebulae, and solar winds are massive plasma structures. The extreme temperatures in space naturally create conditions where electrons detach from atoms. Studying plasma helps scientists understand cosmic events, solar activity, and even potential risks like solar storms that can affect satellites and Earth’s power grids.
