Is there such a possibility? Controllable nuclear fusion cannot be realized at all. In fact, science and technology are the use of various elements, and the elements in the universe are basically available on the earth, and there are other places in the universe, and the elements that are not on the earth have the same life span. Very short and unstable elements. The current equipment can find elements hundreds of millions of light-years away, basically confirming that as long as the stable elements in the universe are on the earth, technology is to use the elements reasonably to achieve the desired effect. , But note that there are two parts: means and elements. Is it possible that the elements in our universe (that is, materials under normal conditions) simply cannot support controllable nuclear fusion? No matter how advanced the technology is, it won’t work for hundreds of millions of years. It can’t be realized, including the strong force materials mentioned by Liu, and I feel that the dark forest is not established. The earth has sent a message to the universe before. I believe that if there is a civilization that can master controllable nuclear fusion, then follow In terms of the scale of the universe, this civilization is also an astronomical figure. They may also send out more obvious signals like the universe before, or the interstellar ships in the universe should be flying all over the sky, and they can be discovered with an astronomical telescope. Clues, but in fact there is no. It is very likely that controllable nuclear fusion cannot be realized at all. Controlled nuclear fusion should be the only way to achieve interplanetary flight and completely solve the energy problem. I also hope that this can be achieved, but there is Maybe the elements of our universe cannot support controlled nuclear fusion.
I have also thought about this issue in depth. The question of the subject is very reasonable, but I have a slightly different view on the conclusion1. Controlled nuclear fusion is possible. Biology is the existence of inverse entropy. For any living being, energy has the supreme significance. In addition to maintaining one’s own integrity, energy can also support many other activities. In fact, the energy level that humans can control determines the boundaries of human capabilities. For example, in an era without a steam engine, it is impossible for subways to exist, and pumping water is not as fast as water seepage; in an era without airplanes, it is impossible for people to run to 1000KM/h, and the limit for four legs is only 100 kilometers per hour. . The decisive factor behind this is the energy level we can control. Nuclear fusion is the highest level of energy that mankind currently has access to. There are no theoretical obstacles. The problems faced are mainly engineering problems. Even if some necessary elements are lacking on the earth, humans can still produce elements by collision of particles. It’s just that the cost is a little higher to exchange energy for materials. As long as the sun is still working, humans still have the opportunity to accumulate enough energy to achieve this supreme goal. 2. Interstellar navigation with people as the main body is unlikely, and interstellar navigation with information as the main body may be able to perform manned interstellar navigation under conventional knowledge. I am not optimistic about it. You can understand the earth as a beaker and the sun as an alcohol lamp. Under the action of the alcohol lamp, a dynamic equilibrium biochemical reaction is maintained in the beaker, and human is only one of the products of the biochemical reaction. In this analogy, you will find that humans are actually integrated with the earth and life on the earth, and it is impossible for humans to survive long-term without the earth. Therefore, if you want to carry out interstellar travel, you must establish an ecosystem that mimics the earth to be able to support the long interstellar travel. It is extremely difficult to understand the relationship between the various roles in the ecosystem, and the ecosystem cannot be too small. The smaller the ecosystem, the easier it is to collapse due to accidental disturbances. You can imagine how big this interstellar spacecraft will be. Even if there is nuclear fusion, it is necessary to figure out where the fuel comes from. Therefore, the difficulty of interstellar navigation is far more difficult than nuclear fusion. Even with the bonus of nuclear fusion, the feasibility is minimal. Is there a workaround? In fact, there are people. The biggest burden of interstellar navigation is people. If people are removed, the spacecraft can be greatly simplified. For example, the huge ecological support system can be removed. So why do interstellar voyages have to bring people, and what are the indispensable qualities of people? In fact, the meaning of interstellar travel is to explore, perceive, and transform other planets, so as to spread human civilization, and these things do not necessarily need to be carried by humans. The probability of interstellar travel in the future is such a form that mankind has assembled all the technologies to create a group of robot astronauts with a nearly infinite lifespan. These robot astronauts carry all the knowledge and necessary tools of human beings and sail to each other in interstellar spacecraft. The purpose is to use the materials and energy of the destination to try to replicate the ecological environment of the earth. At the same time, a communication station was established to communicate with the mother planet of the earth, indicating the expansion of human territory. This kind of interstellar travel is called information-based interstellar travel. It only needs to inject information at the destination to detonate the myth of creation. I know that I succeeded, and I saw that I succeeded, in fact, the experience is very close-human beings are plants of the interstellar age from a certain perspective.
