"The fairy spirit is fluttering, thousands of stars, the stars are moving, and thousands of miles are overwhelmed."
This is a very unique scene in Xianxia-themed film and television dramas, which not only has a beautiful picture, but also makes people feel infinitely reverie, as if telling about the thousand-year-old strangeness inherited from ancient times to the present, making people more and more curious about the fantasy world depicted in these film and television dramas.
In ancient martial arts, celestial bodies can be made to float in the universe, so does this wonderful power that makes the stars float really exists in the inheritance left by ancient martial arts?
With the development of modern science and technology, the understanding of the universe is becoming more and more deep, so how do all the planets in the universe "float"?
What is the force that holds them all along?
1. The wonderful power in ancient martial arts.
In some ancient Xianxia film and television dramas, there are many wonderful ideas that make people reverie, such as in "Xuanyuan Sword: Traces of Heaven", there are overlapping celestial formations, not only that, but the protagonists in the film and television can also use their own power to make these celestial bodies float in the universe, and the stillness of each planet has its own formation, which is very mysterious.
In the stories of ancient martial arts, there are often protagonists or some masters who can create celestial bodies through their own power, and the celestial bodies they create have different powers, and in the development of the story, they also lead to a lot of magical stories, so how did these celestial bodies come about?
In real life, celestial bodies are not made up of individual planets, but huge celestial bodies composed of galaxies, galaxy clusters, etc.
But the floating of planets in the universe does have some similarities with the celestial bodies in these ancient martial arts, so what kind of power does the floating of these celestial bodies in reality rely on?
What kind of mystery is hidden in this?
What is the force that keeps these celestial bodies moving?
2. Cognition and evolution of the universe.
From ancient times to the present, all objects in the universe are gradually formed under their own movement and interaction, including everything on the earth, as well as our solar system, the Milky Way, the universe, etc.
The Big Bang theory is considered to be the most plausible explanation for the birth of the universe, which began 13.8 billion years ago, and since then, the universe has continued to expand and evolve until it is today.
But in the evolution of the universe, there are countless unsolved mysteries, such as what is the curvature of the universe?
This question has also been studied for a long time, and in general, there are three possible cases of the curvature of the universe.
Regarding the curvature of the universe, there was a hypothesis that the energy density in the universe was relatively thin, but soon after, the expansion of the universe gradually decreased due to the gravitational pull of the universe, and finally became contracted, forming a closed space, and this hypothesis is called the open universe.
There is also the hypothesis that there are two possibilities for the curvature of the universe, which are positive curvature and negative curvature, and this hypothesis is called the open junction universe, and in the absence of curvature, the universe is an infinite space.
But no matter what kind of curvature, the gravitational pull of the stars is ubiquitous, and it is also the most powerful physical force in the universe, and it is the existence of gravity that makes the celestial bodies in the universe "float" all the time.
Gravity is the force that attracts all things to each other, and Einstein's general theory of relativity has another explanation for gravity, which believes that gravity is generated by the curvature of space-time caused by the mass and energy of the stars, which determines the movement mode and path of objects, so that stars can rely on gravity to attract and move each other.
3. The power to maintain the stable operation of the universe.
Gravity is undoubtedly the most important force in the universe, and it is precisely because of its existence that the celestial bodies in the universe have been running stably, and in the evolution of the universe, there are still many unsolved mysteries, such as the problem of dark matter.
What kind of substance is dark matter?
During the formation of the universe, dark matter was considered a substance in the universe, but as the name suggests, dark matter is a substance that does not emit light or heat.
But even so, dark matter occupies more than 90% of the mass of the universe and is the most important component of the universe, but the nature of dark matter is still poorly understood.
It also has little effect on the production of light, so dark matter cannot be observed from the outside, but it has an extremely strong gravitational pull, and it is precisely because of the existence of dark matter that the celestial bodies in the universe have been running stably.
It can pull planets and galaxy clusters together without letting them disperse, so that everything in the universe has a law to follow, and this strong gravitational pull comes from the existence of dark matter, which is also a very important force.
It is precisely because of the existence of dark matter that the effect of gravity is more powerful, which can maintain the stable operation of the universe, so that all celestial bodies can exist stably, and people's research on dark matter is also deepening, which also brings more possibilities for people's understanding of the universe.
epilogue
In ancient martial arts, there was a setting of fairy spirit fluttering and thousands of stars, but in real life, celestial bodies floating in the universe were not magical powers exerted by immortals, but were constrained by physical laws.
The floating of celestial bodies is closely related to human beings, and it is precisely by relying on these mysterious powers that human beings can experience the awe and wonder of the universe.
People's exploration of the universe has not stopped, but just like the setting in ancient martial arts, these mysterious forces may be physical laws that we have not yet fully understood, and all we can do is continue to explore and discover.
