With the development of science and technology, new research has found that the super-strong force field of wormhole can be neutralized by negative mass to stabilize the energy field of wormhole. Scientists believe that antimatter also has a "negative mass" relative to the "positive matter" that produces energy, and can absorb all the energy around it. Like wormholes, "negative mass" was once thought to exist only in theory. However, many laboratories in the world have successfully proved that "negative mass" can exist in the real world and captured a small amount of "negative mass" in space through spacecraft.
According to the calculation of researchers in the Department of Physics of the University of Washington, the "negative mass" can be used to control the "wormhole". They pointed out that "negative mass" can enlarge the original tiny "wormhole" enough for the spacecraft to pass through. Their research results have aroused great interest from the aerospace departments of various countries, and many countries are considering funding the research of "wormholes", hoping that "wormholes" can be really used for space navigation. According to the general theory of relativity, planets and other objects try to travel through space-time in a straight line, but because space-time is curved, their paths seem to be bent by the gravitational field. It's like putting a heavy object on a rubber film to represent a star. Heavy objects will press down the rubber film and bend at the stars. Now, if you roll balls on the rubber film, the balls represent planets, and they revolve around the stars. We have proved from practice that time and space will bend. For four-dimensional space, most people may just think that there is a time axis on the axis of length, width and height, but most people still know little about it. Simply put, the coordinate axis of four-dimensional space can be regarded as the axis of three-dimensional space bending, changing or expanding according to certain laws. An expert once made an analogy: we assume that some plane people living in two-dimensional space have only one plane concept. If you want to lock a person in a two-dimensional plane, you just need to draw a circle around him with a line, so that he can't walk out of this circle in two-dimensional space anyway. Now we who live in three-dimensional space interfere with it. We just need to take the two-dimensional person out of the circle from the third direction (that is, the direction in which the heel axis indicates the height) and put it back to other places in the two-dimensional space. In our view, this is a simple thing, but in the eyes of two-dimensional film makers, this is undoubtedly incredible: how can a person suddenly disappear and then appear in another place when he is locked in a circle! For us three-dimensional people, the situation in four-dimensional space is very similar to the above explanation. If we can overcome the four-dimensional space, it is not impossible to cross the three-dimensional space in an instant. Let's do another experiment: weave some rubber ropes into a net according to the pattern of longitude and latitude, and flatten them. We can treat it as a two-dimensional plane approximately, and then put a ball on the net, and the rubber net sinks under the gravity of the ball, forming a three-dimensional space. However, it is often unclear to observe this space from the inside, and those two-dimensional people may not realize that their living space has been distorted. When they come to this depression from the plane, and the depression is deep to a certain extent, or distorted to a certain extent, people from the two-dimensional plane may freely travel back and forth to the three-dimensional space. It is this change that will make the organism evolve from a two-dimensional organism to a more advanced organism, and then develop a three-dimensional consciousness. An example of a small ball that causes space distortion in our three-dimensional world may be a black hole. A black hole is actually a phenomenon existing in four-dimensional space, or a channel connecting the three-dimensional world with the four-dimensional space (of course, I don't mean "who wants to go to four-dimensional space, please go to a black hole". According to our current understanding, it will only be "dead and broke." It is possible for us to find a way to overcome the four-dimensional space through in-depth study of black holes. In that case, Wapu will jump and fly (warp space), and the distance to our destination will be shorter. Or simply, fold the paper in half and the destination will be close at hand. Now scientists have confirmed that the huge gravitational field of black holes does distort the surrounding space. According to the general theory of relativity, we think that light travels in a straight line in normal space, but compared with stars, black holes are very dense and small in size, and the gravity generated by them makes it impossible for light to escape from their surfaces. This has changed our interpretation of time and space. We now say that the gravitational field of a black hole is enough to distort space. Theoretically, when space is distorted, matter will accumulate with the direction of space distortion. If we can take a photo of a beam of light shooting at the black hole, we will find that the light becomes decomposed into a stream of matter, pointing to the center of the black hole, because the huge gravity of the black hole has distorted the surrounding space. But in fact, such photos can't be taken. Because black holes absorb light, we can't see it with the naked eye. We can only estimate its shape by the change of energy. Now scientists guess that it is a sphere with four-dimensional concept. From the point of view of quantum mechanics, black holes will also volatilize, because the more accurate the particle velocity, the less accurate the position. In other words, particles that follow faster than photons also exist in theory. Finding them will cost a lot of money to build a more powerful particle collider. In addition, it is speculated that the precondition of equal concentration is the interaction of positive and negative energy. Some people speculate that black holes are a bridge between positive and negative energy worlds. Some people even speculate that negative energy leads to the distortion of space. To answer the second question, I can understand your question as: What is space and what is the essence of space? Space is a component of concrete things, a manifestation of movement, a cognitive object that people decompose and abstract from concrete things, a unity of opposites composed of absolute and relatively abstract things, meta-ontology and meta-entity, and an ordinary individual member that exists in the world collective, which cannot be felt by people, but can be recognized by people. It is a concrete thing that the eyes can see and the hands can touch, and it is a concrete thing that is in a certain spatial position, and there are specific regulations on space. There is no specific thing without spatial regulation. Space and time are the unity of opposites; Space includes cosmic space, cyberspace, ideological space, mathematical space and so on, all of which belong to the category of space and have their own specific meanings. We can learn about space through the Madebo hemispheric experiment. When exploring the meaning and essence of space, we might as well recall the "Madeborg Hemisphere Experiment". In this experiment, the pressure difference between the inside and outside of the experimental sphere is formed by pumping away the air inside the experimental sphere, which proves the existence of air and air pressure and makes people gradually understand what vacuum looks like. If the sphere is filled with water at the beginning of the experiment, the same result can be obtained. Limited by technical conditions, it is difficult to ensure that all gas molecules in the sphere are extracted, and at that time, people did not realize that there are basic particles in nature, some of which may pass through the sphere. Then the so-called vacuum can only refer to places where material is scarce to a certain extent. At present, people are not sure to find an absolute vacuum, that is, a place where there is no matter at any time. Although people can't be sure whether there is an absolute vacuum, if we think further about the experiment, there is still a place that is not occupied by any substance at a certain moment. There are two reasons. First, after removing air or water molecules, the mass of the experimental sphere decreases, but the volume and energy of the sphere have not changed significantly, which shows that the place originally occupied by air or water is empty; Secondly, if the empty space inside the sphere is filled with subatomic particles, according to the current physical knowledge, the mass of the experimental sphere will be greatly increased, but the result is not the case. Therefore, the experiment shows that although there may be gas molecules or elementary particles left inside the experimental sphere, at least one place in the sphere is not occupied by any substance at a certain moment, even a tiny place, even for a moment. Then, we can call such a place pure space, that is, pure space refers to a place that is not occupied by any substance at a certain moment. The place occupied by matter (which can be long or short) can be called material space, in other words, material space is the place where matter exists. Material space and pure space can be transformed with the movement of matter, and all pure space and material space together form a complete absolute space, which is called space for short. A part of space is a local space, which can be a single pure space or material space, or a combination of both. Taking the local space in the experimental sphere as an example, whether it is in a vacuum state or filled with atmospheric gas or liquid water, it is a combination of pure space and material space. The difference is that the proportion of pure space and material space is different at different times. What is the essence of space? Cosmic matter itself is space. Science has not found "empty" space. Space is closer to the category of rules. The motion process of space matter is time. The moving matter is time and space. Space-time is the universe. I hope my answer is helpful to you. I hope it can be adopted. Thank you.
