How does science explain supernatural events?

  You may not know that hundreds of thousands of people around the world are actively searching for ghosts. There are currently about 2,000 active amateur ghost hunting organizations in the United States. The UK even produced a ghost-related TV show “Ghost Haunted”, which collects “ghost” legends from all over the UK and organizes groups to “catch ghosts.”
  Screams, black shadows, girls in white, and wandering ghosts, people can always describe the “ghosts” they see vividly. As the saying goes, “seeing is believing”, people always believe in what they see with their own eyes, but is this really the case? Can we believe in the supernatural phenomena we hear or see?
  Capturing ghosts from the sound
  In 1988, a researcher named Vic Tandy of Coventry University in the United Kingdom, together with a colleague, conducted a study on the supernatural phenomenon that occurred in the medical device manufacturing shop in Tandy Town. According to the store’s employees, they often feel creepy in the store and can see some supernatural phenomena in the room. For further research, Tandy personally lived in the store for a while. At first, Tandy didn’t notice anything abnormal, until one day, he felt a cold breath rushing over his face. After confirming that the medical gas tank at the scene did not leak, Tandy returned to his desk, but at this moment, he saw a gray figure in a corner. When Tandy plucked up the courage to see more clearly, it disappeared.
  In an experiment of cutting metal, Tandy noticed that a foil in the laboratory was shaking crazily on the floor like an evil in the loud noise. From this unexpected discovery, Tandy was inspired. He guessed whether it was the sound energy that caused the supernatural experience of him and his colleagues.
  Tandy and his colleagues once again entered the haunted equipment store. They turned off a ventilation fan in the building where the store was located. A miracle happened and the ghost disappeared. Subsequent sonic measurements confirmed that the infrasound in the “haunted” room was 18.98 Hz, which was just close to the 18 Hz that makes the eyeballs vibrate, so people have hallucinations. Tandy went to some rumored haunted basements, castles, churches, etc. to conduct inspections. As expected, relatively strong infrasound waves were detected in doorways and corridors.
  The hearing range of a normal person is between 20 and 20000 Hertz (Hz). Sounds below or above this frequency range are difficult for human ears to hear. In the haunted house, people’s supernatural experience may be caused by infrasound waves in the range of 20 Hz lower than normal hearing.
  Infrasound waves are widely present in nature and human activities. From marine storms, tsunamis, earthquakes, aurora, etc. in nature, to various operating machinery of human beings, infrasound waves may occur. The frequency of infrasound is very low, but the penetrating power is very strong. Infrasound waves below 10 Hz can travel across mountains and oceans and travel thousands of kilometers away. In the summer of 1883, the Krakatau volcano between Sumatra and Java in Indonesia experienced an eruption that shocked the world. The infrasound waves produced once orbited the earth 3 times and lasted 108 hours.
  Studies have found that infrasound waves can also cause great interference to human health. Since infrasound waves are close to the natural frequencies of human organs, resonance is likely to occur. If the energy of infrasound waves with a frequency of 0.5 to 10 Hz is large enough, they can stimulate the auditory vestibule in the ear or the balance organs of the inner ear, and can also stimulate people to hyperventilate. Infrasound waves of 4 to 8 Hz can generate resonance in the human abdominal cavity, which can cause strong resonance in the heart and damage to the lung wall. According to research, infrasound may be included in the melody played by the famous “murder music” “Black Sunday”.
  Knowing the principle of infrasound waves, it is not difficult to explain why places with strong infrasound waves are often “haunted”. Infrasound waves, because they can “resonate” with people, make people uneasy, including feeling nervous and uncomfortable, and infrasound waves can also make people’s eyeballs vibrate, making people see things that don’t exist at all, plus deep claustrophobia In the environment, the dim light easily arouses people’s deep sense of fear. If you think of ghost stories again, people can easily believe that they have discovered ghosts.
  The magnetic field in the cold
  for another explanation supernatural phenomenon is the magnetic field. There may be no ghosts around us, but electromagnetic fields generated by power lines and electronic devices surround us all the time. Could these electronic devices be the culprit?
  Some experiments have shown that electromagnetic fields may have such effects. In 2000, Michael Bursinger, a cognitive neuroscientist from Laurent University in Canada, and colleagues conducted an experiment using magnetic fields. The subject of the experiment was a person who experienced a supernatural event. The 45-year-old man claimed to have had a terrible experience earlier and encountered a real ghost. Bersinger and his colleagues tried to use magnetic fields to “conjure” ghosts that the experiencer had seen before. The “artificial ghost” experiment was very successful. Under the influence of a certain magnetic field, the experiencer saw the ghost he had encountered before. Bersinger wrote this experiment as a report and published it in the journal Perception and Motor Skills.
  In the following year, in the same journal, Michael Bersinger and his colleagues published another paper, which introduced the supernatural experience of a young girl. The girl recounted that she had been conceived by the Holy Spirit, and she could often feel a baby sitting on her left shoulder. In subsequent investigations, Bersinger and colleagues found that in the girl’s early life, her brain had been injured. But this is not the only reason for the girl’s supernatural experience. There is an alarm clock beside the girl’s bed. The pulsed electromagnetic waves generated by this alarm clock are very similar to the electromagnetic waves that cause epilepsy rats. Remove the alarm clock and the girl’s vision disappeared immediately. Professor Bersinger believes that electromagnetic fields will affect the normal activities of the temporal lobe of the brain, and the temporal lobe plays a function of integrating information. Disorders of the temporal lobe function can give people the illusion that “something else exists” in the room.
  The temporoparietal complex in the brain is responsible for processing visual and tactile signals. The balance and spatial information sent from the inner ear, as well as the sensory signals transmitted by joints, tendons, and muscles, all need to be processed by the temporoparietal complex. Combining these information, one can feel the existence of one’s own body and the relative position between oneself and the surrounding environment. Once the operation stimulates the brain tissue at the junction of the temporal lobe and the parietal lobe, that is, the temporal-parietal junction, people’s self-awareness will be greatly affected. Therefore, scientists generally believe that people whose brains have been damaged are more likely to have illusions.
  And the ubiquitous magnetic field around us may also affect people’s spiritual experience through the normal activities of the temporal lobe of the brain.
  The role of psychological cues
  There are also scientists who believe that there are no ghosts in the world, but the human heart, and the supernatural phenomenon may be just a brain conjecture. Research has found that people living in a ghost culture are more likely to understand the supernatural phenomena in their lives as ghosts. Furthermore, in a specific environment, the illusion of encountering ghosts occurs. “Once bitten by a snake, ten years afraid of well ropes” contains this principle.
  In psychology, psychological suggestion refers to the process by which people apply images through thoughts, words or individuals, which can change certain mental states of people. For example, when walking at night and hearing the sound of rustling in the bushes, you often cannot help but run wildly. People who have a strong ghost complex tend to feel nervous when passing by legendary ghost-infested places. Due to the self-suggestion effect of the ghost concept, certain areas of the cerebral cortex are in a state of extreme excitement, and the eyes and ears are searching for suspicious movements. At this time, hallucinations or auditory hallucinations occur. For another example, when passing by a cemetery, grave heads or trees are often seen as ghosts. If you hear any rustling sound again, those timid people may be really frightened and weakened.
  Believe it or not, mysterious ghost stories will emerge in endlessly, human history will still be entangled with ghosts, and scientists will always be trapped in a maze of finding answers. Although we may still have lingering fears in the face of ghost stories, we don’t know how to distinguish them, but we should not trust our intuition too much, but solve the mystery of ghosts in a scientific spirit.
