      Light sail 2.0

      Light sail propulsion is a mature engineering technology, and there are many aerospace application cases. For example, China Tianfan 1, guangfan 1, 2 and Icarus launched by global crowdfunding, etc. These cases require the use of external sunlight and a huge light receiving area. The light sail 2.0 proposed in this paper does not need to rely on sunlight and huge light receiving area.

      In order to better understand the structure and principle of guangfan 2.0. Let's make a hypothesis first. Two opposite light sails aim at each other and emit laser in space. Both light sails can reflect laser. Once emitted, the laser will go back and forth in the middle of the light sail until it is annihilated in a vacuum. These two light sails will be able to obtain great acceleration. In fact, there is no such light sail, because time and space are curved and light sails cannot aim at each other. There are two similar light sails in nature. For example, two stars can be regarded as two light sails, and the stars get the power to stay away from each other. These two light sails can also be regarded as two galaxies and two galaxy clusters. These two light sails are two abstract points of these giants. When these two points are accelerated by the light shooting at each other, they will continue to accelerate. After infinite years, these two points similar to light sails will be away from each other at an approximate speed of light. If these two points are the ideal light sail, the mass of the light sail will increase and the space-time around it will bend. If these two points are stars, their distance will increase, and gravity will produce collapse and black holes. If these are two galaxies, it will produce the expansion of the universe we observe. If these two points are galaxy clusters, they will produce galaxies farther away from us, and the faster they move away from us.

      If you can understand the above paragraph, light can change time and space, and the change of time and space can make matter move.

      If you only let light move in one direction, that's the principle of light sail. The principle of light sail 2.0 is similar to the principle of cosmic expansion. Light or electromagnetic waves go back and forth between two points. One point gets one-way acceleration and the other point gets the same acceleration, but the speed is opposite. Turn the acceleration of one point into light emission, and the other point can move forward. This is the principle of light sail 2.0.

      For more than 20 years, emdrive cannot be falsified or applied. The principle is not clear, and the exaggerated publicity of the inventor is one of the reasons. The optical sail 2.0 mentioned in this paper can also be used to explain emdrive, but the structure of optical sail 2.0 is brand-new. The principle of optical sail 2.0 tells us that we can use the ultra long electromagnetic wave to X-ray as the power to change space-time. As long as it is properly designed, it can produce an effect similar to the expansion of the universe. Considering the current level of human technology, solid-state microwave is used to form a steady-state resonant standing wave with reasonable structure. You can get the effect of cosmic expansion. We then emit the kinetic energy and energy obtained from one end of the standing wave through infrared radiation. The other end of the standing wave will gain power in the opposite direction. One end of the power is equivalent to a light sail. The light pressure of the microwave makes it move forward. The end emitting infrared radiation is like light pressure turbocharging, which upgrades the light pressure. By now, you have gained all the knowledge of the principle of guangfan 2.0. In the following article, we will make a detailed design.

      Even if the principle of light sail 2.0 is feasible, is its thrust large enough? The external thrust of light sail 2.0 depends on the external infrared radiation at one end of the standing wave. If the radiated energy is large enough, the thrust is large enough. We know that the light receiving area of guangfan II is only 32 square meters, but it can also obtain considerable thrust. The input power of guangfan II is about 50KW sunlight, and a large amount of these input power is not used for work. If guangfan 2.0 inputs power at 50KW, the thrust obtained will be much greater than guangfan 2. Although this thrust is very small, it can be done without external working medium. There will be a large number of application scenarios in space.

      Light sail 2.0 can also be used as a driving force for star interstellar travel. It will also be easy to change stars in the solar system, and human wealth will increase from planet to planet.

      What is the experimental significance of light sail 2.0? Human science is based on some core world views, in which the earth is the center of the universe and the scientific core of Archimedes era. Newton's scientific system is a world view of the universe centered on the sun. According to relativity, quantum mechanics is a cosmology with space-time bending and energy transfer as its object. None of these scientific systems can explain the principle of cosmic expansion. Through a seemingly random light sail 2.0 experiment. Can enhance human understanding of the universe.

      By using the physical principles in the conjecture, if guangfan 2.0 can obtain thrust, these physical principles will also be verified. Guangfan 2.0 will bring a qualitative leap to aerospace technology
