Plasma is the least understood state of matter. We are not talking about biological material but an unstable soup of electrons, positive ions, and atoms. After solid, liquid, and gas, plasma is the fourth state of matter, and it makes up 99.9% of the universe. The Sun is a ball of plasma along with some gas. The northern and southern lights are plasma. We see plasma in lightning and in the plasma globes in museum gift shops. In recent years, scientists have produced plasma, and engineers have used it to make the chips used in computers, automobiles, television sets, and musical greeting cards. Plasma also stimulates the light we get from fluorescent lamps and neon signs.
In the 19th century, the Finnish physicist Karl Selim Lemström noticed that fir trees near the Arctic Circle grew faster when the aurora borealis was the strongest. From that beginning, scientists have found that not only does plasma enhance plant growth, but it also can kill the pathogens of bacteria, fungi, and viruses. In addition, some experiments have indicated that plasma can stimulate the growth of blood vessels in animal’s skin.
Experiments in various countries have shown that seeds treated with plasma germinate and sprout more quickly. Other scientists are experimenting with sending an electric current through the air to create plasma, releasing ionized nitrogen, which plants need for growth. Those nitrogen ions can dissolve in plasma-treated water that can both irrigate and fertilize plants. The U.S. Department of Agriculture Research Center in Wyndmoor, Pennsylvania, is experimenting with using plasma in agriculture to replace chemical fertilizers, insecticides, and fungicides.
The early Earth had the right environment for plasma production, which could have stimulated plant growth in the sea and on land. This new understanding of plasma is one more testimonial to the wisdom built into the creation. The fact that 99.9% of all matter in the cosmos is plasma emphasizes how precious the physical design of our planet is. The solid matter which makes up the Earth is nurtured by liquid water, gaseous air, and plasma.
The more we know of the creation, the more we understand the power and wisdom of the Creator. “The heavens declare the glory of God and the firmament shows His handiwork” (Psalms 19:1). When we see the Sun, the stars, the galaxies, the northern lights, and the lightning, we see plasma, a tool God uses to shape the creation and mold the world around us.
