We often see the concept of parallel universes and multidimensional spaces in various science fiction movies, but most people only eat the melons. Only by combining the plots of the movie can we have a somewhat shallow understanding of these concepts. Actually, it is not just us. Most physicists have not really figured out the conceptual conjectures put forward in string theory until now, because there is no technology that can confirm these conjectures. Now, Brian Greene, a physicist at Columbia University in the United States, has used VR technology to start real experiments and explorations of these previous conjectures in order to prove the incredible ideas and opinions in string theory. In related works published by Greene, Greene pointed out that from the point of view of string theory, the basic units of nature are not electrons, photons, neutrinos, quarks, and the like. The substances that look like particles are actually A very small closed string, different vibrations and movements of the closed string produce a variety of different elementary particles. In addition, the space we live in is a complex of ten physical spaces plus a time attribute space. These multidimensional spaces are not perceived by humans because they are all "compacted" in a small size. In the space. In fact, since the embryonic form of the string theory was born in 1968, human beings have not demonstrated this “fantasy†theory through actual experimental operations. On the one hand, because most conjectures about string theory are always overturned by various reasons, on the other hand, because current high-speed particle accelerators are not powerful enough to perform simulation experiments based on relevant conjectures. So Greene began to find a way to use VR technology to corroborate the conjectures and theories of string theory. At present, he has created a VR robot demonstration teaching course. Through wearable devices, students can intuitively watch various amplified particles of matter, including their vibrations and trajectories, in the classroom. In addition, using VR technology, it is also possible to project a four-dimensional hypercube described in terms of string theory in a classroom with 24 faces, 16 vertices, and 8 cubic cells. It is understood that Greene is planning to use this futuristic course as an important part of its research field. In the subsequent studies, it will not only focus on teaching students to visually conjecture and theory in string theory, but also use it. VR technology further proves the concepts in the multi-dimensional space.
