Musk just unveiled his latest breakthrough: a warp-drive starship! Elon, Musk. He told people to forget months of travel to Mars; now we're talking about minutes of travel to Mars. According to Elon, SpaceX has successfully tested warp drive technology, bending spacetime itself to make faster-than-light travel a reality. This isn't just a great idea - it's the beginning of something that could revolutionize the way we explore the universe. This is great news, and Musk's spirit of exploration could open up a new chapter in science, but his so-called successful warp drive experiment is not recognized by the scientific community because it is a confusing and unrealistic concept. It is important to mention here that the concept of warp drive is not a complete and scientific concept, and his spacetime distortion is actually a distorted image of another set of physical mechanisms. Musk's warp drive theory has many uncertainties, and he will one day realize that he has spent a lot of money but has not produced the desired results: However, the issue of creating faster-than-light travel has been discussed several times in China. There are even meetings organized by State Councilor Song Jian and Vice Minister of Science and Technology Cheng Jinpei to discuss these issues. Professor Pei Yuanji of the University of Science and Technology of China has already given the design of the actual superluminal electron accelerator. Academician Cheng Jinpei said meaningfully that he hoped that the people sitting in the front row of the next meeting would be young people with black hair, but this wish is still difficult to achieve. Young people are different from old people. For the sake of life and professional titles, the topics they make must be consistent with the mainstream views, otherwise it will be difficult to get financial support and there will be gaps. The reconstruction project of the superluminal electron accelerator has been affirmed by experts at the accelerator annual meeting of the Xi'an Institute of Nuclear Research in 2002. It has been 20 years since then, but it has not been started due to lack of financial resources. Almost all those who explore superluminal speed are retired elderly people who are not restricted by the system. In recent years, flag bearers such as Professor Zhang Cao, Professor Zhang Junhao, Researcher Lin Jin, and Professor Huang Zhixun have passed away one after another, and this motivation has been weakened. I hope that this time, with the help of Musk, the flame of the superluminal engine can be ignited. In order to illustrate the principle of superluminal acceleration, I would like to introduce and recommend this paper written by American author Michael James Young based on the ideas of Chinese scholars: "Derivation of Special Relativity from the Theory of Subsonic Compressible Aerodynamics". This article by American friend Michael James Young on the derivation of special relativity from subsonic compressible aerodynamics theory is completely consistent with the discussion in several conferences in China, so we are very interested in this article. I would like to translate it and introduce it to you.

   He changed the convective wave equation in subsonic compressible flow into a mathematical transformation based on the convective wave equation for incompressible flow. This is exactly the same as what the special theory of relativity does. The physical basis of the Lorentz transformation used in relativity has far-reaching significance.     At the beginning of the article, he briefly reviewed the evolution of using incompressible flow solutions for airfoil design instead of high-speed wind tunnel testing. This in turn led him to introduce the history of aerodynamicists using the Prandtl-Groult space contraction method to replace compressibility effects before World War II. In fact, he did not know that even in modern times, the design of our subsonic aircraft, especially drones, is still basically based on low-speed wind tunnel experiments, and these transformations are still in use. And there are new revisions. The key is that later in the article, he mentioned through deduction that the matrix expressions for formally representing relativistic speed, acceleration and mass can be obtained without Einstein's conjecture or the so-called metric invariance. These same matrix expressions can be obtained from compressible and incompressible flow systems. In theory, considering a linear transformation fixed to the vehicle and a fixed spatial coordinate reference system can develop the same expressions in relativity. The mathematical intersection of special relativity and compressible flow theory is not generally understood or appreciated by physicists and electromagnetic field experts outside the field of subsonic aerodynamics, so it will become an increasingly compelling topic for us to explore. The author's approach in this regard is admirable, although unconventional. In particular, he mentions that the use and interpretation of coordinate transformations may be confounded by the use of distance and time measuring devices, because these devices are also affected by the compressibility of the medium itself. If an acoustic timing device is used in a vehicle connected to external conditions, its time delay measurement will also be affected by the change in air compressibility when the speed changes. Therefore, if the hypothesis that speed affects the compressibility of the air is rejected, then the difference in the time delay measurement of the acoustic device will be wrongly interpreted as a distortion of the space and time coordinates. This is exactly the same distortion of space and time that modern physicists are so fond of talking about.     The author, like me, uses derivation to show that the Lorentz factor is not special in the usual sense. Instead, it is a compressibility correction factor that arises from ignoring compressibility in the formulation of the convective wave equation. When compressibility is ignored, the correction factor is needed to compensate for the mathematical artifacts caused by the contraction of space and the dilation of time. If this law is applied to the medium of light propagation, and it is acknowledged that the medium of light is compressible, then under the assumption that the speed of light is infinite and cannot be exceeded, this transformation must be used. The core of this transformation is the Lorentz factor. The author mentioned that the difference between the development of aerodynamics and physics theory is that most aerodynamicists accepted the concept of air compressibility, but most physicists rejected the concept of vacuum compressibility. The twelve coordinate transformations, plus the formulas for subsonic speed, acceleration, and mass are completely derived through a brute force iterative program, which utilizes the mathematical characteristics of the partial differential equations of compressible flow and its transformation to incompressible flow in classical fluid dynamics. This argument was also carried out by computer derivation thirty years ago, although I only did it in two dimensions and did not have the mathematical derivation of the twelve sets of transformations that the author has now done in three dimensions, but it also illustrates the problem. That is, it also shows that there is no need to introduce additional assumptions about the positioning and timing between clocks, chord lengths, and acceleration planes.      In conclusion, I agree with the author that checking the coordinate transformation, velocity addition and mass equations for subsonic conditions shows that they are mathematically identical to the equations used in special relativity to describe the motion of electromagnetic waves or particles, substituting the speed of sound in air with the speed of light in a vacuum. The convective wave equation for compressible flow and the wave equation of special relativity match exactly only if the equations of special relativity are assumed to be based on vacuum conditions, where the vacuum is represented by an incompressible flow system with a fixed spatial reference system (IS). The correct starting form to use the convective wave equation is the one that includes time and space cross derivatives. Any mathematical transformation that removes these cross derivatives will convert the resulting equations into a non-physical form representing a fictitious fluid.

Theoretical discussions have led us to a surprising conclusion: if we want to accelerate electrons to the speed of light in an accelerator,

Just like Professor Pei Yuanji of USTC and Xintie yang of NPU designed the accelerator extension, we should reduce the energy instead of increasing it.

When the detection method is not necessarily able to measure the speed of the electron, we can measure whether its radiation is subluminal radiation or superluminal radiation. I hope that friends who are concerned about this research will contact me and help Musk deepen his research in this area and avoid metaphysical detours.
