In the atmosphere, a kind of chemically active particle is formed
under the combined effect of sunlight, cosmic rays and electric
fields. The particles condense into one nucleus after another,
gathering under the action of the electromagnetic field and
expanding like a rolling snowball, resulting in a ball of different
sizes. This composition under the physical and chemical reaction
includes the "cold ball” and the "bright ball".
The “cold ball” has no light and no radiation of energy. It can
exist for a long time. The shape of the cold ball is like a football,
which dark and opaque and only visible during the day. Scientists
call it black lightning.
The “bright ball”, white or citric, is a chemical luminescent
structure. It appears without any kind of thunderbolt, moving freely
in the air or staying on the ground, or moving quickly along strange
tracks, darkening and brightening time to time.
The Nature of Black Lightning
The cause of black lightning can't be explained by scientists.
For a long time, people only think of blue and white lightning,
which is the natural phenomenon of atmospheric discharge in
the air, usually accompanied by dazzling light. Black lightning
doesn’t shine and was never seen.
On June 23rd, 1974, Soviet astronomer Chernoff once saw a black
lightning in the city of Zagrel: it was intense ball lightning
at first, followed by a black cloud that looked like a fog-like
Black lightning is produced by molecular aerosol aggregates
produced by the sun, cosmic light, cloud electric field, strip
lightning and other physical and chemical factors in the atmosphere
over the long term. These aggregates are hot, electrically charged
matter that can easily explode or turn into ball lightning.
Usually, black lightning does not occur near the ground, but if it does,
it tends to fall near the trees, masts, houses, and metals, in the form
of a lump or mud pie, which looks like a ball of dirt.
Black lightning is the most dangerous and harmful type of lightning
because it carries a lot of energy with its shape, color and position
easy to be neglected.
Black lightning is small. It’s hard to catch it on radar, and its
preference to metal makes it known to pilots as "dark thunder in the
sky". Any contact with black lightening would be too dreadful to be
thought of. When black lightning is too close to the ground, it is
easy to be mistaken for a bird or something else. If it is touched,
it will explode immediately.
The Mystery of the Devastation of Mohenjo Daro
In 1922, Indian archaeologist Ra Jay Banerjee discovered the ruins
of the ancient city of Mohenjo Daro from a group of mounds along the
lower Indus river. The excavation revealed that the ancient city was
indeed destroyed by a fire and a huge explosion. The huge blast
destroyed all the buildings within a radius of about 1000 meters.
The posture of the excavated skeletal showed that many people were
still walking on the streets before the disaster struck. What was
it that caused the destruction of the city? After years of research,
scientists concluded that it was caused by black lightning.
Scientists believe that the atmospheric conditions that create black
lightning also produce large amounts of toxic substances. Apparently,
the inhabitants of the ancient city were first tormented by this
poisonous air for a while, and then killed by the violent explosions.
A large amount of black lightning may also be there. Whenever one of
them explodes, there will a chain reaction, followed by other black
lightning. When the blast reaches the ground, it destroys the city.
In addition, just like ball lightning, general lightning protection
facilities do not work on black lightning. Flexible black lightning
often can land smoothly near oil tanks, gas tanks, transformers,
explosives depots, regardless of the compact lightening facilities.
At this time, do not get close to it or touch it, because when black
lightning is approached, it can easily become ball lightning, and ball
lightning is more likely to explode.
In the broad daylight of Moscow, a colonel in Soviet army called
Baogordanov also witnessed a smoothly moving, steaming black lightning,
measuring between a quarter and a third of a meter in diameter. It
looked like a fog-like condensate, with a reddish shadow behind and a
dark brown halo around. It was like a red ball of fire, which rolled
quickly and exploded soon.
