The myth that the foil cap is able to protect the human brain from all kinds of scans from space has long been dispelled. The Internet literally exploded from information about these amazing miracle hats, they say, they protect your brain from radio waves. Also, wearing it, you can not be afraid of an alien attack through exposure to the brain. It was believed that all the negative effects are simply reflected back without causing any harm. However, thanks to a number of studies, it was revealed that the foil can in no way contribute to the reflection of various signals back to the universe. This was written by ToRead and Science.

Each person has the right to opinions and beliefs. Many of those who feared any tracking from space and all kinds of control over the mind, vehemently believed in such an invention as a foil hat. It was believed that such a "device" made of foil is a serious invention that will serve as a salvation from magnetic waves. Some, by the way, still carry them, believing that they will serve as an excellent weapon that will either send all the negative signals back into space, or simply suppress them.
A series of experiments were carried out on such caps, the material for the manufacture of which was ordinary aluminum foil, which made it clear that they could not be effective in protecting against control from space.
Research has been fairly thorough. Several varieties of such a cap were used: classical form, Fez and Centurion. Tests were conducted on volunteers. A foil cap was put on and receiving antennas were installed. They created specific frequencies, and the Agilent analyzer, which was connected to them, checked the incoming signals. The experiment showed that people's opinion that a foil cap blocks signals is wrong. And on the contrary, the signals were amplified, not weakened.
This signal was analyzed by Agilent, and the result showed that frequency amplification occurs literally in any area of ββthe brain. Therefore, a foil hat is not only ineffective, but also harmful. And during the war with aliens, it will help not humanity, but enemies from outer space.
Nick Pope, a well-known narrow-minded UFO research project director for the UK Department of Defense, said our planet was completely open to invading extraterrestrial civilizations. After all, since when he closed the UFO research department, no one has been monitoring unexplained phenomena . He also noted that all flying unidentified objects, as it was before, are nowhere marked and completely ignored. If suddenly someone reports that he saw something inexplicable, the Ministry will not react in any way.
Pope was the project manager from 1991 to 1994. For all these years of work, he revealed a lot of all kinds of signs of the presence of alien creatures. According to him, the Earth is in no way protected from an attack from outer space. However, an extraterrestrial civilization has never shown signs of hostility, therefore, there are no significant reasons for alarm. However, you should not believe that if the war of the worlds suddenly begins, mankind will be saved by foil caps.
