Natural phenomena

Ball lightning

• Ball lightning is probably the most famous unexplained electrical phenomena. This term refers to flaming, spherical objects that differ in the diameter of a hole up to several meters. Ball lightning is usually associated with thunderstorms, but lasts much longer than normal lightning. The phenomenon was the subject of research, since 1834, the English physician and researcher William Snow Harris introduced the concept into the scientific field, but even now there is no generally accepted explanation of ball lightning.

Bermuda Triangle

• If there is a place known for the occurrence of mysterious phenomena and strange events that scientists cannot figure out, it is the Bermuda Triangle. In this region in the western North Atlantic, a number of aircraft and ships are said to have disappeared under mysterious circumstances. Scientists tend to attribute the disappearances to several coincidences, such as terrible weather, ocean currents, human error, and even methane bubbles.

Valley lights

• Male humpback whales can make long and very complex "sounds" that were once thought necessary to attract females, but studies have shown that the sound often attracts other males. In addition, individuals can recognize each other's songs and distribute them to other populations. So the singing of humpback whales remains a mystery.

Witch Circles

• Found in the arid grasslands of western South Africa, witch circles are circular patches of barren land. Usually found with monospecific herbaceous vegetation, circles vary in diameter from 2 to 15 m. The origin and history of fairy circles has long been a puzzle, and even today, scientists do not know exactly how they appeared. One favorite assumption is that termites are responsible for the circles, but the area of the phenomenon is much wider than that of termites.

Volcanic Light

• Scientists have found that similar volcanic light is observed before an earthquake and occurs in areas where a large volcanic eruption is about to occur. Recent research suggests that light can be caused by elements that energize rocks' natural electrical charge, causing them to sparkle and shine.
