Without a doubt, England is a land of ghosts. Its history is rife with legends about the ghosts of young white women who fell victim to unbridled jealousy, cruel criminals, or murderous kings. Although no Englishman would ever admit it, everyone is subconsciously ready to enter the spirit world. Coventry University computer scientist Vick Tandy always dismissed ghost stories as fairy tales and never took them seriously. He was once spending an evening working in his laboratory as usual when he suddenly felt a chill. Vick felt someone watching him with a menacing gaze.
Then the terrifying "something" took on a gray, material form, moved across the room, and approached the scientist. In the vague outline, Vick saw legs, arms, and a mist that he identified as a head, with a dark spot in the center where the mouth should have been. A moment later, it vanished into thin air without a trace.
InfrasoundSoon after Vick recovered from his initial shock and fear, he began working as a scientist: he began searching for the causes of the unusual phenomenon. Hallucinations might have been the simplest explanation. On the other hand, Vick took no medications and drank alcohol and coffee in moderation. As for supernatural forces, Vick didn't consider them. So Vick Tandy began searching for ordinary physical factors that could explain the phenomenon.
Soon, Vick Tandy began to discover factors quite by accident. His hobby, fencing, helped him along. One day, he saw a "ghost" behind another scientist, who brought his rapier to the laboratory to properly adjust it for an upcoming fencing tournament. Then, Vick felt the mishandled blade begin to vibrate more and more, as if touched by an invisible hand.
"Some invisible hand" might be an explanation ordinary people might accept, but not a scientist. That's why Vick Tandy concluded that the blade's movement was caused by resonance vibrations induced by sound waves. The same thing happens when we see circles in tea when music is playing in the room. However, the laboratory was silent. To be sure, Vick Tandy measured the sound intensity in the laboratory using special instruments. Imagine his surprise when he saw that the sound wave in the room was very faint, and the scientist couldn't hear it. It was infrasound. It took the scientist a long time to discover the source of the infrasound, which turned out to be emitted by a fan in an air conditioner. As soon as the air conditioner was turned off, the blade stopped vibrating.The infrasound itself was quite surprising. Many sailors have long pondered the mystery of the "Flying Dutchmen," ships that plied the seas without crews. While such ships were in good working order, there were no people on board. Where did they disappear? The story of the Mary Celeste, the last of such ships, is well-known. This magnificent schooner was spotted on the high seas by the crew of another ship [Dei Gratia]. When the ship approached the Mary Celeste and its sailors boarded, they were astonished to find a hot lunch and fresh notes from the captain's logbook. However, there were no people on board. They vanished without leaving the slightest trace.
For decades, no one was able to solve this mystery, but it was eventually revealed that the explanation for this phenomenon was infrasound. As it turns out, infrasound with a frequency of 7 Hz is emitted by ocean waves under certain conditions. Infrasound at 7 Hz negatively affects humans: people go crazy, go mad, and throw themselves overboard to save their lives.
Tandy Vick speculated that his night vision might also have been related to infrasound. When he measured the infrasound in the laboratory, the frequency was 18.98 Hz, the frequency at which the eyeball begins to resonate. Ultimately, Vick Tandy used sound waves to produce his visions and optical illusions: he saw a figure that didn't actually exist.
Further investigation into the phenomenon revealed that sound waves of such low frequency can often occur naturally. Infrasound is created when strong gusts of wind strike chimneys or towers. Such powerful bass can penetrate even very thick walls. Such sound waves create a roaring sound in tunnel-like passages. This is why people often encounter ghosts in the long, serpentine, tunnel-like corridors of old castles. Strong winds are a common atmospheric phenomenon in Great Britain.
Vick Tandy published his research in the Bulletin of the Society of Physical Research. This society was founded in 1822 to unite English parapsychologists and naturalists. The society works to find plausible explanations for paranormal phenomena. Understandably, a professional ghost buster is enthusiastic about Tandy's theory. Leading parapsychologists in Great Britain believed that this theory could explain many mysterious phenomena.However, other scientists expressed doubts about this theory. Physicists testing the effects of infrasound on the human body reported that volunteers in these experiments complained of fatigue and high pressure in the eyes and ears, but never reported hallucinations or ghosts. Physicists also noted that drivers also did not experience optical illusions when their cars overcame strong air resistance at truly high speeds and high-frequency infrasound waves.
On the one hand, it seems the mystery of ghosts has been solved, but on the other, many questions remain unanswered. Many people in the UK continue to see ghosts. However, it's not entirely clear whether these are beings from the world of the dead or merely optical illusions. Indeed, studying this phenomenon is fascinating: nature allows its mysteries to be solved more and more quickly, but suddenly, before scientists' eyes, it slams doors and creates new paths leading to the solution of these mysteries.
