Ball lightning:
reality or myth? Automatic translate

Ball lightning remains one of the most mysterious and controversial topics in modern atmospheric physics. This phenomenon, a luminous spherical object observed during thunderstorms, has attracted the attention of scientists, researchers, and observers worldwide for centuries. Despite thousands of testimonies and dozens of theoretical models, the nature of ball lightning remains unsolved, making it one of the most intriguing phenomena in modern science.

Historical context and first descriptions

The study of ball lightning dates back several centuries. The earliest documented observation in England was made by the Benedictine monk Gervasius of Canterbury Cathedral in 1195, where he described "a wondrous sign descending near London" as a dense dark cloud from which emerged a white substance that assumed a spherical shape.

Systematic study of the phenomenon began in the 19th century thanks to the French physicist and astronomer François Arago, who was the first to collect and systematize eyewitness accounts. In the second half of the 19th century, he described approximately 30 cases of ball lightning observations. Many of Arago’s contemporaries dismissed ball lightning as an optical illusion, which significantly limited scientific interest in the phenomenon.

During the Soviet period, academician Pyotr Kapitsa and Igor Stakhanov made significant contributions to the study of this phenomenon. Kapitsa suggested that the glowing balls could be gas discharges moving along the lines of force of an electromagnetic wave generated during a thunderstorm.

Modern observations and eyewitness accounts

According to modern estimates, approximately one in 150 people claims to have seen ball lightning. Typical observations describe luminous objects approximately 20 centimeters in diameter, although sizes can vary from a few centimeters to several meters. The duration of such objects typically ranges from a few seconds to several minutes.

Characteristic features described by witnesses include the objects’ ability to move horizontally, hover in mid-air, penetrate walls and windows without visible damage, and produce hissing sounds and a distinctive ozone odor. Many witnesses report profound psychological effects from the sighting, ranging from amazement to intense fear.

Professor Anatoly Nikitin of the Russian Academy of Sciences describes an incident in 1948 in Tushino, where 17-year-old Ida Naboko (later a physicist and mathematician) observed a pulsating reddish-blue-violet object 15-20 centimeters in diameter that moved toward a power line and exploded upon contact with a metal pole, leaving traces of oxidized metal.

Scientific theories and models

There are many theories attempting to explain the nature of ball lightning. Key research areas include plasma models, electromagnetic theories, chemical hypotheses, and nanoparticle-based models.

Plasma and electromagnetic models

One of the most developed theories suggests that ball lightning is a plasma formation. Shironosov’s model is based on the resonant nature of the phenomenon, where the plasma is held by its own magnetic fields of tens of megaoersteds. According to this theory, ball lightning is a self-stable plasma with an ordered, synchronous motion of charged particles.

The relativistic-microwave theory proposed by Wu explains the formation of ball lightning by the action of a relativistic electron beam, which generates intense microwave radiation. This radiation ionizes the air, and the radiation pressure creates a spherical plasma bubble that stably holds the radiation.

Silicon nanoparticle model

The widely known theory of Abrahamson and Dinniss suggests that ball lightning is formed when ordinary lightning strikes the ground, vaporizing soil minerals. Carbon in the soil reduces silicon oxides to elemental silicon, creating a gas of energetic silicon atoms. These then recombine into nanoparticles or filaments, which, floating in the air, react with oxygen, releasing heat and light.

Laboratory experiments by Paiva and colleagues demonstrated the possibility of creating glowing balls by electrical discharge through pure silicon. The resulting objects possessed many properties attributed to natural ball lightning, including a lifetime of several seconds.

Modern experimental approaches

Researchers from the Max Planck Institute created balls of glowing plasma, 10-20 centimeters in diameter, floating above water and lasting for about half a second. Physicists from Moscow State University have developed a model according to which ball lightning most closely resembles a hot-air balloon filled with hot gas.

A team from Tel Aviv University used a "microwave drill" — a device powered by a 600-watt magnetron — to create laboratory analogues. The drill’s energy created a molten hot spot in a solid object, and when the drill was removed, some of the superheated material was pulled out, forming a fiery column that then transformed into a bright, glowing ball.

Controversial hypotheses and criticism

Theory of magnetic hallucinations

Austrian scientists Josef Peer and Alexander Kendl from the University of Innsbruck proposed an alternative explanation for some of the observed ball lightning phenomena. They investigated the effects of magnetic fields generated by lightning discharges on the human brain.

According to their hypothesis, phosphenes — visual images that appear when exposed to strong electromagnetic fields — arisen in the visual centers of the cerebral cortex. The researchers compare this effect to transcranial magnetic stimulation, where magnetic pulses trigger phosphenes.

Calculations show that fluctuating magnetic fields can create hallucinations of round, glowing objects in observers within 20-200 meters of a lightning strike. Scientists estimate that in approximately one percent of close encounters with lightning, a fluctuating magnetic field can trigger hallucinations.

Limitations of the hallucination theory

Critics note that the theory of magnetic hallucinations cannot explain all aspects of the phenomenon. Severe burns and fatalities attributed to ball lightning require a material explanation. Furthermore, hallucinations cannot explain the physical traces left by ball lightning — damage to glass, metal surfaces, and other materials.

Physical evidence and material traces

One of the key arguments in favor of the real existence of ball lightning is the documented cases of material damage and physical traces.

Spectral analysis of 2012

A breakthrough occurred in 2012 when Chinese scientists from Northwest Normal University in Lanzhou conducted a study. While studying ordinary lightning on the Qinghai Plateau, they accidentally recorded the spectrum and high-speed video of ball lightning. An object approximately 5 meters in diameter appeared immediately after the lightning struck the ground, 900 meters away from the instruments.

Spectral analysis revealed emission lines of silicon, iron, and calcium — elements expected in soil minerals according to Abrahamson’s theory. This became the first instrumental confirmation of the composition of ball lightning and indirectly supported the hypothesis of silicon nanoparticles.

Cases of destruction and damage

Documented cases of physical impact from ball lightning include building destruction, damage to electronic equipment, and personal injury. In 2013, in the village of Mogsokhon in the Kizhinginsky District of Buryatia, ball lightning penetrated the roof of a house and exploded inside, destroying half the structure. The homeowner suffered serious injuries, and neighbors’ appliances were damaged.

A similar incident occurred in 2021 in the village of Medvedka in the Perm region, where ball lightning entered a house through a window, traveled through all the rooms, and exited through another window, leaving charred ceilings and window frames.

Glass damage analysis

A detailed study of window damage attributed to ball lightning was conducted by Polish scientists. In 2001, in the village of Rozkopaczów, the trajectory of the object was analyzed based on the nature of the damage to two windows. An analysis of the Wallner lines on the surface of the radial cracks allowed us to determine the direction of the force that caused the glass breakage.

The study revealed that the object impacted the windows from the outside, which contradicted eyewitness accounts of ball lightning moving through the room. Scientists hypothesized the existence of a solid core within ball lightning, capable of mechanical impact and explosion.

Laboratory experiments and artificial reproduction

Numerous research groups around the world have attempted to create ball lightning analogues in the laboratory. The most successful experiments involve the use of microwave radiation, electrical discharges in water, and exposure to various materials.

Microwave experiments

A team from Tel Aviv University created a "microwave drill" based on a 600-watt magnetron. Directing a beam through a sharpened rod into a solid object made of glass, silicon, or other materials created a molten hot spot. When the drill was removed, some of the superheated material was drawn out, forming a fiery column, which then collapsed into a bright, glowing ball just over 2.5 centimeters in size, lasting for about 10 milliseconds.

Russian physicists from the Kapitsa Institute have developed a setup for creating glowing plasmoids above the surface of water using an electric discharge. The experiment is based on a Russian concept, scientifically developed in the institute’s former Berlin laboratory, where plasma diagnostic methods were used.

Nanoparticle research

A team from the European Synchrotron Radiation Facility used small-angle X-ray scattering to study the internal structure of artificially generated fireballs. The results revealed the presence of hot nanoparticles with an average size of 50 nanometers and a volume fraction of approximately 10^-7, persisting for two seconds after the microwave source was turned off.

Current state of research

Despite centuries of study, the nature of ball lightning remains a mystery. The lack of a generally accepted theory is explained by the phenomenon’s complexity, rarity, and short duration. Modern researchers continue to collect eyewitness accounts, conduct laboratory experiments, and develop theoretical models.

Richard Sonnenfeld of the New Mexico Institute of Technology and Carl Stephan of Texas State University have created a website to collect eyewitness accounts to better understand the basic characteristics of the phenomenon. They are comparing the data with weather radar systems to characterize the factors that contribute to ball lightning formation.

Latest theoretical approaches

Modern theories include dark matter-based models, which consider ball lightning to be a manifestation of axion quark clumps. Other studies suggest a connection with magnetic monopoles to explain the energetic characteristics of the phenomenon.

The dynamic electric capacitor model describes ball lightning as an ensemble of positively charged elements within a spherical shell of polarized water molecules. According to this model, the dynamic capacitor represents a system of cyclically moving electrons and ions.

Safety and practical aspects

Ball lightning can pose a serious danger to people and property. Burns, electric shocks, and even deaths have been documented from contact with this phenomenon. Ball lightning’s high-frequency radio waves, in the 1-10 centimeter range, can be absorbed by liquid water, which, upon close contact with the body, can cause blood heating and muscle tissue rupture.

Safety recommendations include closing windows and doors during thunderstorms to prevent drafts that could attract ball lightning. When observing a luminous object, it is recommended to remain calm, avoid sudden movements, and stay away from the object.

Significance for modern science

The study of ball lightning is crucial for the development of plasma physics, atmospheric electricity, and the understanding of extreme states of matter. Successful reproduction of the phenomenon in the laboratory could lead to new technologies in energy, materials processing, and plasma technology.

The research also contributes to the development of lightning protection methods in the aviation and energy sectors. Understanding the mechanisms of ball lightning formation and behavior can help create more effective lightning protection systems for buildings and electronic equipment.

The phenomenon of ball lightning remains one of the greatest mysteries of modern physics. Thousands of eyewitness accounts, physical evidence of damage, and the first instrumental measurements convincingly demonstrate the reality of the phenomenon. However, the lack of a unified theory explaining all the observed characteristics leaves many questions open.

Modern laboratory experiments demonstrate the possibility of creating objects visually resembling ball lightning, but their connection to the natural phenomenon remains uncertain. Further research, combining theoretical modeling, laboratory experiments, and systematic observational data collection, is needed to definitively resolve this scientific mystery.
