Many cosmologists, if you ask them, what is the significance of research? If they can't answer, they will tell you that it is their hobby. If you don't ask cosmologists, ask mathematicians who study number theory. What's the point of studying mathematics? They will tell you that mathematics is their life. What is the significance of basic disciplines? Without the accumulation of basic disciplines, there will be no progress in applied technology. Our seemingly meaningless research today may be the basis of a key technology in the future. Of course, some research may never be applied to technology, but does that mean it is meaningless? Is it meaningful for human beings to challenge the limits of intelligence? From a scientific point of view, the driving force behind all human preferences is the preservation and transmission of DNA. Including the study of cosmology, its essential significance is actually for the better survival of human beings and the better preservation and transmission of DNA of this species. There is a violent astronomical phenomenon in the universe called supernova explosion. The internal temperature of massive stars is much higher than the surface, and the maximum Supergiant star core temperature exceeds 654.38+0 trillion. For a stable star, the theoretical upper limit of the core temperature is 6 billion K. Above this temperature, the photon energy emitted by the matter inside the star will be high enough to be converted into positive and negative electron pairs when colliding with each other. Such a reaction will make the star unstable and eventually be destroyed in a huge explosion. Supernova explosion will give a fatal blow to life on the planet within a few light years. Studying cosmology can avoid risks in advance. Red giant stars are the stage of stars. When a star goes through its long youth-the main sequence star stage and enters the old age, it will first become a red giant. Red giant is a short-term unstable stage experienced by stars in the later stage of combustion. Depending on the quality of a star, its life span is only a few million years, which is very short compared with the stable period of billions or even billions of years. The surface temperature of the star in the red giant period is relatively low, but it is extremely bright because of its huge volume. Through the cooperative research of international astronomers, it is found that through careful observation of several aging and expanding stars in the depths of the universe and their surrounding environment, the true face of the decaying star in the universe, the red giant, is further revealed. The research results of cosmology enable us to clearly foresee the scene when the end of the earth comes billions of years later: the earth on which we live will eventually face the ruthless devouring of high temperature and heat. Because astronomers have estimated that stars will expand outward after death, and the sun that once gave the earth warm sunshine will eventually dry the earth completely. By studying cosmology, we can predict our human risks in advance, inspire us to develop science and technology, and avoid human risks in the future.
In the future of mankind, we will definitely get rid of the shackles of the earth and drive a starship to conquer the vast space. We will encounter all kinds of dangers, all kinds of radiation, and meteorite impact will bring life threats to astronauts. There is also a kind of black hole that is the most deadly threat to astronauts. Black holes are celestial bodies existing in space in modern general relativity. The gravity of a black hole is so great that the escape velocity in the event horizon is greater than the speed of light. Through the study of cosmology, we can know where the black hole is and where the boundary of its gravitational trap is, so that the spacecraft can avoid it in advance and make space navigation safer.
As we all know, the speed of light limits the speed of all substances, thus limiting human beings to a very small area forever. By studying cosmology, scientists can find ways to operate faster than light, such as wormholes, such as high-dimensional transitions, such as curvature-driven. Cosmological research is to constantly challenge the existing, conquer the unknown and find a better theory. Maybe these theories are all science fiction now, but if you don't study them, you will never make progress. To study cosmology is to test all the possibilities one by one and turn the impossible into the possible. The universe will die, stars and black holes will evaporate, and even protons may decay. Eventually, the temperature in the universe is close to absolute zero, and no life can survive at this time. Studying cosmology, we can find ways to survive, such as re-creating a sub-universe, and migrating all living things to the sub-universe through some technology. Cosmology is the capital of all living things in the universe.
