The emergence of science hundreds of years ago gave mankind a new understanding of the world, and the continuous development of science has quickly ushered in a new era of science and technology. With the help of science and technology, we have a new understanding of many unknown things, and we have also walked out of the earth to see the vast space of the universe.

Newton’s gravitational system gave us a preliminary understanding of the nature of the world, and Einstein’s theory of relativity gave us a new understanding of space. The existence of space-time distortion is a major discovery. It allows scientists to understand There is a better way to explore the mysteries of the universe.

With the deepening of human understanding of time and space, some scientists have proposed string theory. One of its basic ideas is that the basic units of nature are not point particles such as electrons, photons, neutrinos, and quarks, but very small and very small. Small linear “strings”. The different vibrations and motions of the string produce a variety of different elementary particles, and energy and matter can be transformed.

The introduction of string theory also allowed scientists to explore the possibility of multi-dimensional space. If string theory is correct, then multi-dimensional space exists, and scientists also proposed the concept of eleven dimensions. Our universe consists of eleven dimensions. Composed of three dimensions, the space for human existence is just a three-dimensional space.

Scientists also put forward the concept of high-dimensional space and low-dimensional space. In terms of scientific definition, four-dimensional space is an important watershed. The space below four-dimensional is low-dimensional space, and the space above four-dimensional is high-dimensional space.

The low-dimensional space is the existence that we can perceive, while the high-dimensional space has no way of understanding. According to the speculation of scientists, we want to walk into the high-dimensional space and understand and explore the high-dimensional space. Then the four-dimensional space is an important threshold, and its value is beyond our imagination.

Only by breaking through the door of four-dimensional space can we go further and better understand high-dimensional space, and hope to open the door of high-dimensional space. So how is the eleven-dimensional space divided? Scientists follow the law of dimensional space and propose that dimensional space has a conservative increasing law, and the higher-level dimensional space is formed by the superposition of the next-level dimensional space.

The zero-dimensional space has no length, width and height, but a simple point, which we call a singularity, and a black hole is a singularity. One-dimensional space is a line formed by connecting countless points, two-dimensional is a plane composed of lines, and three-dimensional is a solid composed of faces.

The space in which humans live is a three-dimensional space. We can see the length, width and height. What about a four-dimensional space? We must know that after countless three-dimensional solids are superimposed, it is still a solid, but the shape is different, so will such a space be a four-dimensional space? In fact, we cannot simply understand the superposition of spatial dimensions as a superposition of shapes, but a more complicated superposition of time and space.

Scientists understand the four-dimensional space in this way. On the basis of the three-dimensional superposition, the time dimension is added, which means that the four-dimensional space is composed of length, width, height and time. If we stand in a four-dimensional space and observe the human world, it is equivalent to standing in front of the TV and watching the video in it. Everyone’s time track can be repeated by “dragging the progress bar”.

The three-dimensional world in the four-dimensional space is a visual image. Of course, we can only watch these images repeatedly, and we cannot change them. The five-dimensional space is the superposition of the four-dimensional space, and the playback effect will be better. Standing in the five-dimensional space, everything in the four-dimensional space and the three-dimensional space can also be viewed repeatedly, and it is also impossible to intervene in changes.

When it comes to the six-dimensional space, it is a progression of time. The video we can touch is no longer limited to time, but can be switched between the past and the future. It’s just that such things cannot be changed artificially either. We can only watch the progress on the timeline like watching a movie.

Some people may say that after entering a high-dimensional space, one can travel between the past and the future. Does that have the ability to change history? In fact, from a scientific point of view, changing history is unlikely to happen. If history can be changed, then the entire universe may have collapsed long ago, and it may not have existed until now.

Things like the butterfly effect may never happen. Even if we reach a high-dimensional space and have the ability to travel between the past and the future, we can only be a spectator. We can only look at what has happened in history, and what should happen will happen. What will not happen will not happen. This is equivalent to entering a virtual reality world where everything has already happened and we cannot change it.

If the theory of multidimensional space is correct, how can human beings open the door to high-dimensional space? In this regard, scientists have been conducting various explorations and studies, and have put forward some conjecture theories. Some scientists believe that the key to opening the door to high-dimensional space may be the human brain.

Scientists have conducted a lot of research on the human brain. The more they study, the more confusing. The complexity and mystery of the brain are far beyond our imagination. In addition to the visible neuron structure in the human brain, consciousness is more mysterious. Consciousness is an intangible and invisible thing, but we can prove the existence of consciousness through a large number of scientific experiments.

What is the essence of consciousness? It is still unclear, and all human behaviors are actually controlled by consciousness. Some scientists speculate that to enter a multidimensional space, perhaps the human body cannot truly enter, and the consciousness body is needed to hope to cross the dimensional barrier. The strange dreams we often make feel very real. It may be something that human consciousness has experienced when entering a higher dimensional space.

Of course, this is just a guess of scientists. We still know nothing about the four-dimensional space and the multi-dimensional space. Whether or not the multi-dimensional space exists is currently unknown. Even if we can prove the existence of multi-dimensional space in the future, it is not so easy to explore the mystery of high-dimensional space. Perhaps the theory of multidimensional space is the ultimate mystery of the universe, and science needs to be developed to a very high level before there is hope to explore it. The current scientific strength of mankind is still too weak.
