Many UFOs can be rock lightning

Some unidentified flying objects (UFOs) can be rock lightning and atmospheric phenomena.

Stephen Hughes, an astrophysicist from the Queensland University of Technology in Australia, began studying UFOs since many large meteor stars appeared in Brisbane's city in southeastern Queensland state in 2006, the BBC said. know. When they appeared, the people also saw a UFO emitting green light flying above the mountains near the city.

Stone lightning is still one of the mysteries for the scientific world. Many witnesses saw lightning that described them as brightly colored fireballs, which existed for a few seconds. These spheres move around. Sometimes they dive or fly up, sneak into the house or through the glass door. They often disappear after an explosion. It is thought that clay rock is born by thunder in storms, but many people still see them in the days when the weather is normal.

Dr. Hughes thinks that an electric field exists between the ionosphere and the ground. When meteor stars rush into the earth's atmosphere, they carry many charged particles and conductive materials. Their presence in the air increases the electric field strength between the ionosphere and the ground.

' It is very likely that when meteor stars rush through the ionosphere, they generate electrical currents. Although electric currents only last for a few seconds, their intensity is still strong enough to make rock lightning , "Hughes said.

Hughes considered the ionosphere and the ground as the two poles of a battery. When the two poles are connected by a wire, the current will flow through the wire. Meteors act as wires.

When meteor stars fly into the atmosphere, they can create an electrical current between the ionosphere and the ground. Sometimes these currents are strong enough to form clayey rock. Photo: scienceray.com.

Many other scientists believe that charges can create aerial glowing spheres during the plunge from the ionosphere to the ground. Those gas globes are a form of rock lightning.

10 years ago, Dr. John Abrahamson , a lecturer of the University of Canterbury in New Zealand, hypothesized the formation of rock lightning. According to him, clay rock formed when a lightning bolt struck down evaporating silicon dioxide in the soil. This silicon vapor condenses in the form of fine dust, bound together by electrical charges, creating a floating, oxidized and glowing sphere. Another possibility is that ionized air (by lightning) interacts with water, forming a hot plasma sphere with an ionic shell and cold water.

Abrahamson describes Dr. Hughes's work as ' relatively feasible ' and says that public opinion has to wait a long time before someone finds the perfect answer to the presence of UFOs and lightning.
