This site introduces the theory, experiment and data analyses of the engine of the man-made flying saucer, and introduces a new state of matter: foggoid, in Chapter 6, which is as follows. ¡¡ Chapter 6 A new state of matter: foggoid state ¡¡ 1. Foggoid As we know, when a body is near a black hole, the strong tidal force will break up the body. Similarly, it can be seen from Chapter 4 that in an antigravitational field, the gravitational field matter (gfm) of each part of a body is dragged by the antigravitational field and forms the gfm ball of this part of the body. When a body is controlled by a strong enough antigravitational field, owing to the macroscopic quantum effect and owing to the breakdown of the weak equivalence principle in the quantum domain, each part of the body will go its own way in an uncertain way according to the wave function of its own gfm ball particle, and therefore, overcoming the attractive forces between each other, the various parts of the body will separate up, even into a cloud of fog-like matter, and become the foggoid. This state of matter can be called the foggoid state. Foggoid has different degrees of breaking up, or in other words, different degrees of gathering, and hence has different phases. Different phases of foggoid can coexist. Being less restricted in foggoid, electrons move more freely, so that foggoid has the electromagnetic phenomena. When the antigravitational field weakens, some or all parts of a cloud of foggoid may gather or half gather into one or a number of new entities because of the attractive forces among them. ¡¡ Note: The weak equivalence principle states that all sufficiently small test bodies fall with an equal acceleration independently of their mass in a gravitational field. ¡¡ 2. Spacetime, structures, and functions It can be seen from Chapter 4 that in an antigravitational field, a particle of the foggoid moves according to the wave function of its own gfm ball particle, and therefore it has the spacetime of its gfm ball particle. It can be known from quantum mechanics that such spacetime has large degrees of uncertainty and that this particle has nonlocal-spacetime quantum correlations with other bodies. Hence in the foggoid, the uncertainty in the motion of a photon that moves freely in vacuum increases, which makes the light ray between two points deviate from a straight line; that is, the geodesic between the two points deviates from a straight line of the flat spacetime. According to the general theory of relativity, this means time passes slower in the foggoid. If some parts of a cloud of fog-like foggoid half gather, then the cloud of foggoid has internal structures and their functions in the above spacetime. ¡¡ 3. Antigravitation engine effect As is stated in Section 2 of Chapter 2, a body and its gfm interact with each other and are relatively independent of each other. From the rotation device, the disturbance device and the set of equations of the antigravitation engine, it can be known that a gfm eddy, a disturbance nearby and a small enough | capital sigma a' | can jointly cause the antigravitation engine effect, which, when strong enough, can move a body and can make a body break up into countless tiny pieces, thus becoming the foggoid. ¡¡ 4. Connections with some phenomena When a ball of foggoid with internal structures falls into a crop field, a crop circle in a complex pattern may be formed. Sometimes UFOs can be seen to break up or get together and to be now visible, now invisible. In the Bermuda Triangle there have been reports of the disappearing planes or ships. In the book "Time Storms" by Jenny Randles, there are abundant case files on strange fogs and their effects. These phenomena may be related to the foggoid and its phase transition. As is stated in Section 2 of Chapter 2, matter has the antigravitational field. Therefore the stars have the antigravitational fields; the human body has the antigravitational field. ¡¡ 5. Acupuncture and foggoid Many facts demonstrate that acupuncture needle rotation is related to the antigravitation engine effect and that what acupuncture readjusts is the foggoid of the substances of the human body. Such foggoid communicates with the foggoid of the substances of the natural world. ¡¡ 6. Quasars, dark matter and foggoid At the early time of the universe expanding, the antigravitational field was extremely strong. From Paragraph 2 of Section 1 in this chapter, it can be known that before ordinary states of matter were formed, there would have been the foggoid state first. The foggoid in the excitation state had strong ability to emit light; it also had a large degree of time dilation, and hence the enormous redshift. Such foggoids were probably quasars. From Paragraph 1 of Section 2 in this chapter, it can be known that the coordinates of a foggoid particle in the 4-dimension spacetime have large degrees of uncertainty and its coordinate on the 1-dimension time axis is not necessarily the 0-dimension point of "present time", but can be any point on a line segment. If its coordinate on the 1-dimension time axis is far away from the point of "present", then the particle has no way to act on an object which has a small degree of uncertainty in the time, except that the particle shows gravitation because of its making the 4-dimension spacetime curved. Hence, the foggoid which is in the ground state and is not luminous might be a part of the dark matter in the universe. ¡¡ 7. The motion of the gfm, the geometric structure of spacetime, and nonlocal quantum correlations According to the postulates in Chapter 2, Section 2, Gfm waves are the material base of the de Broglie waves. Hence the motion of the gfm tells a particle how to move. According to the general theory of relativity, the geometric structure of spacetime tells a particle how to move. Hence the motion of the gfm participates in deciding the geometric structure of spacetime. The geometric structure of spacetime can be propagated not only by ordinary matter, but also by the foggoid, including the ground state foggoid whose coordinate on the 1-dimension time axis is a negative value. Hence there exist the nonlocal quantum correlations among particles. ¡¡ 8. Vacuum and the non-present-time foggoid The experiments that demonstrate the nonlocal quantum correlations show that everywhere in vacuum there exists the foggoid whose coordinate on the 1-dimension time axis is far away from the point of "present time", or in other words, part of vacuum is the non-present-time foggoid. Hence, though rich in contents, vacuum shows only very small energy density at the point of "present time". ¡¡ 9. Instruments that can receive information from the non-present-time foggoid If an instrument is in the foggoid state whose degree of gathering is quite large, then it still can work, but it has a larger degree of uncertainty in the time than when in the ordinary state. Such an instrument can receive from the non-present-time foggoid part of the information, which can not be received by ordinary instruments. ¡¡ 10. The time of the large-scale structures of the universe passes slower Since the expansion of the universe is accelerating, the antigravitational field plays a dominant part in the large-scale scope of the universe. Hence, seen from the large-scale scope of the universe, matter is in the foggoid state. The time dilation of the foggoid causes the time of the large-scale structures of the universe to pass slower than the time of the small-scale structures of the universe.
