From 1970s to 1980s, the US military conducted a series of experiments to explore time and space, which was called the Montauk Project. The predecessor of the Montauk project is the Philadelphia experiment of 1942. Radar was just invented at that time. In order to obtain the stealth ability of warships to radar waves, the US military conducted experiments on the destroyer "Edrich". An omni-directional antenna is installed on the main stern of the warship, and two energy coils are placed on the deck, which are powered by the generator on board. At the beginning of the experiment, some changes took place, and the people on board became restless. Except for the people in the main control room, the main control room was heavily shielded by metal. Later, the main person in charge of the experiment, the inventor of the energy coil, a superphysicist claimed to have been warned by aliens and suggested suspending the experiment. The military thought this reason was unacceptable, so the experimental team began to slow down deliberately, and the experiment had to continue after the main person in charge and members changed. The second and third experiments were even more disastrous. The crew on the deck panicked and fled everywhere, and some people ignited a fire. The generator was running wildly and completely out of control. Finally, Edrich disappeared from people's sight and moved to a place 7000 kilometers away. The Philadelphia experiment was forced to stop, and its by-product was the discovery of long-distance transmission objects.

In the 1960s, some experimenters spontaneously organized themselves to continue their research. In order to get military aid, they claimed that they could develop a machine to control people's spiritual will and let enemy soldiers surrender on the battlefield. The inventor of the energy coil, a super physicist, was re-appointed as the main person in charge of the experiment, and the Montauk project was officially launched. The plan is to develop a mind-reading technique first. This device has three receiving channels, X, Y and Z, which receive the radio waves emitted by the human body respectively. After being processed and analyzed by a large computer, the contents in the experimenter's mind can be read. It is said that the prototype of mind reading was provided by sirian. Haunters Duncan, another outstanding super physicist, appeared in the experiment. When he sits in the experimenter's chair, what he thinks can be displayed around Montauk Air Force Base through equipment. For example, when he thinks of a building in his mind, a building appears around the base, and sometimes the glass of the base is completely broken. With the deepening of the experiment, more strange things were discovered. For example, Duncan thought in the morning, and it didn't appear until the afternoon. The base often had some strange phenomena without warning. It was later discovered that what Duncan was thinking today happened yesterday in advance. In order to study this unexplained phenomenon, the researchers redeveloped a triangular antenna, which is 30 meters high and 40 meters wide and installed in a deep well with a depth of 90 meters. In most cases, the experimenter is Duncan, and only when he is in poor health will he switch to other haunters, but the technical condition of the antenna needs two to three days to adjust. When Duncan sat in the chair and did the experiment, he soon went into a state of absence. If he wants to see the world events from 1980 to 1990, he can see them by entering the time tunnel [1]. (At that time, the experimental time was 1980) The time tunnel is a spiral entrance channel with light at the exit. The outlet can be programmed by the machine. If it is not set in advance, the exit is the corresponding surface of Montauk base. At the entrance of just visiting, people feel suddenly dragged in, and it is possible to meet anyone or anything in the passage. People who enter the time tunnel can't return to the present time until the channel is reopened [2], and the stagnant time in the channel falls into the whirlpool of time [3]. Some people who entered just visiting never came back. It was an accident in the experiment, not intentional. At this point in the experiment, people's mind control is no longer studied, but time is directly studied. Duncan finally understood the essence of time tunnel. When entering two-thirds of the time tunnel, the human soul and body will be separated. This separation will have a strong impact on the human body, and at the same time, the field of vision will be surprisingly expanded. It is also reported that it is possible to feel the existence of advanced intelligent life in space. Except Duncan, a large number of people were sent to just visiting, and most of them never came back. When they returned, they recorded their experiences. Later, many vagrants and drunks were tricked into entering just visiting with cameras on their backs, so as to study videos when they couldn't come back. These tapes are highly confidential. The experiment entered the field of human spirit, which aroused the concern of technicians. They decided to sabotage the whole plan. They programmed Duncan into the startup program, and as long as someone told Duncan in the experiment that it was time, it would have the power to disintegrate the whole plan. One day in 1982, the technicians received the order of continuous operation and did not stop. A few days later, abnormal signs appeared and the whole base was in chaos. Finally, the destroyer Edrich appeared in the just visiting, and the soldiers on fire were running wildly. If they are not careful, there will be a paradox of time [4]. This is caused by the vibration of the experimental system on Edrich, which is similar to the experimental system used in the Montauk project. The accident finally subsided, but the technical machine accumulated for many years became irreparable, and the Montauk plan finally died [5]. The base was permanently closed and all entrances to the basement were filled with concrete. It is said that hundreds of bones were found during the cleaning process. Who started the Montauk project? Is it an alien plan? The devil's masterpiece? Or a CIA scam? These are still a mystery. [6]

[1] The above is my summary based on magazines, and the following is my personal understanding for your reference. Time tunnel is an abstract concept. To understand it, we must start from the one-dimensional world. A straight line is a one-dimensional world, represented by the X axis, and then a straight line is perpendicular to the X axis and named as the Y axis. A plane can be determined by X axis and Y axis, which is a two-dimensional plane world. What should I do to form a two-dimensional plane world from a one-dimensional world? The simplest method is to draw countless straight lines parallel to the X axis along the Y axis, so that countless one-dimensional worlds can form a two-dimensional plane world. Then make a straight line perpendicular to both the X axis and the Y axis, and name it Z axis. A three-dimensional space can be determined by X-axis, Y-axis and Z-axis, which is the three-dimensional world. What should I do to form a three-dimensional world from a two-dimensional plane world? The simplest method is to make countless planes parallel to the X axis and the Y axis along the Z axis, so that countless two-dimensional plane worlds form a three-dimensional world. Is it possible to make a straight line perpendicular to the X axis, Y axis and Z axis at the same time? Modern science believes that the four-dimensional hyperspace is composed of the X-axis, Y-axis and Z-axis of the three-dimensional world plus the U-axis of the time axis. Referring to the method that a one-dimensional world constitutes a two-dimensional plane world or a two-dimensional plane world constitutes a three-dimensional world, a four-dimensional hyperspace can be regarded as consisting of countless three-dimensional worlds along the U axis of the time axis. Please remember this mathematical theoretical model. Now suppose there is a two-dimensional plane world (x, y, Z 1). The leading creatures above are a group of humanoid creatures. They have no sense of sight and hearing, nor the ability to move along the Z axis, so they can't perceive another two-dimensional plane world (X, Y, Z2) parallel to their world one kilometer above their heads. Until one day there was an earthquake, a part of the two-dimensional plane world rose like a mountain peak and finally touched another two-dimensional plane world. This mountain, an approximately cylindrical object, can be called a Z-axis tunnel. Humanoid creatures can reach another two-dimensional plane world through the Z-axis tunnel, but if the mountain shrinks back to the original plane, it is equivalent to the disappearance of the Z-axis tunnel, and the humanoid creatures who reach another two-dimensional plane world will never return to the original two-dimensional plane world, which means that these humanoid creatures disappear in the Z-axis tunnel. Now let's go back to the three-dimensional world (x, y, z, T 1) where we live, and suppose there is another three-dimensional world (x, y, z, T2). Because human beings have no ability to perceive four-dimensional space and move along the U axis (that is, the time axis), they cannot perceive the existence of another three-dimensional world. However, human scientists have found that the powerful electric and magnetic fields emitted by giant antennas can distort the time in local space, form a "mountain of time" and touch another three-dimensional world. Through this "mountain of time", that is, the U-axis tunnel or time tunnel, human beings can travel to another three-dimensional world. The time tunnel in the Montauk project is a three-dimensional space channel composed of powerful electromagnetic fields emitted by several giant antennas, and the time in the channel is distorted, so that the local time coordinate T 1 of our three-dimensional world (that is, the time tunnel) will change dramatically to the time coordinate T2 of another three-dimensional world.

[2] In the Montauk project, the antenna energy is too large, reaching 250 kW, and it is estimated that the continuous power-on time is only one or two days. After shutdown, the time tunnel naturally disappears. If people who enter the time tunnel can't return during the boot time, they can only stay in other time and space. There is another situation, that is, there is no guarantee that you can return smoothly during the boot time. The antenna in the Montauk project is precisely controlled by a large computer, but the technical parameters of the antenna will change, thus changing the shape of the time tunnel. Imagine that if the size, height and position of the rising mountain in the two-dimensional plane world change in translation, it will be difficult for creatures who reach another two-dimensional plane world to return from the original road.

[3] A person who enters the time tunnel may think that he has spent a month, but in fact he must return within one or two days of starting the machine, and this "extra" time is caught in the whirlpool of time.

[4] This is wishful thinking. Edrich has been sold to Spain, and only images appear in the time tunnel. The electromagnetic cloud videotape recorded the scene of the Philadelphia experiment, and then the machine in the Montauk project acted as a player, so there can be no time paradox.

[5] It is wise to abandon the Montauk plan. Personally, there are several important reasons: 1. The technology is not yet mature and perfect. The fragile soul and body of human beings are too dangerous in the transfer of time and space, and will only be restarted when new technologies and new scientific theories appear. 2。 The unstable time tunnel hides risks. Humans can go out through the time tunnel, and unknown creatures can also invade through the time tunnel. Unknown creatures can be higher than humans, and they can also be animals and plants lower than humans. If this kind of creature can reproduce very fast, and at the same time, it can emit substances that are highly toxic to human beings into water and air, then human beings will become extinct.

I think so, too. Why can't America do it?
