Among the five cosmic mysteries that cannot be solved by human beings: "Where did the universe come from", it is terrifying to think about
Remember "The Unsolved Mystery of the World" you watched as a child? Did the strange things in it make you scared to sleep at night when you were young, for fear of aliens coming to kidnap people? In fact, many of these unsolved mysteries have been solved. For example, in Bermuda, there is no so-called triangle area at all, and crop circles, most of which are man-made. A book with unsolved mysteries is in the universe. There are five unsolved mysteries. If they can be solved, it means that humans understand the universe better. So, what are the unsolved mysteries of the universe? There are many mysteries in the universe
Mystery of Light
It is mentioned that light is a frequent visitor in the universe, and the distance in the universe needs to be represented by it. However, light It's a very strange substance. The essence of light is electromagnetic waves in a certain wavelength range, between 780 and 400 nm, which is also the wavelength of electromagnetic waves that human eyes can see. Electromagnetic waves less than or greater than this range are invisible, and the higher the frequency of electromagnetic waves, the greater the energy. For example, the frequency of ultraviolet rays is higher than that of infrared rays. Therefore, we have never heard of infrared antivirus, nor have we seen ultraviolet sensors. The first person to study light in depth was Newton, yes, Newton, the father of mechanics. He was an almighty man who not only studied mechanics, but also optics and mathematics. The wavelength of light and the frequency of Newton create a rainbow through a prism. The original white sunlight is a mixture of 7 colors. Lord Niu believes that light is composed of particles of different colors, and optics is also a kind of "particle" science. However, Newton's opponent, "The King of Springs" Hooker believed that light was a wave, but because of the age, neither of them could provide convincing evidence. The wave-particle dispute about light finally came to an end in the era of another great god, who was Einstein more than 200 years later. The wave-particle dispute between Newton and Hooke Scientists in the Einstein era discovered the wave-particle duality of light after more detailed research. It is both a particle and a wave. The particles that make up light are called photons. It seems that things should be concluded here, but a new question has emerged, photons have no static mass. The particles we often say, such as atoms, protons, electrons, neutrons, etc., all have mass, but photons have no mass. Massive particles cannot break through massless photons no matter how they are accelerated, which is why human beings have yet to discover anything faster than light. Why a substance has no mass, how it was born, these are as inaccessible as the speed of light. The photon of lightwhat is gravity
If according to Newton's formula of universal gravitation, photon is contrary to universal gravitation, it is no wonder that most celestial bodies cannot absorb light. But there is a kind of celestial body, and light can't escape its "palm", it is a black hole. Isn't it said that good light is not bound by universal gravitation? According to Einstein's gravitational field theory, the key to gravitation is the curvature of space-time, and the more massive the celestial body, the greater the curvature of space-time. As long as it is close to the space-time curvature of a substance, it will be attracted. The difference is that the force absorbed by different space-time curvature is different. A black hole with a super curvature of spacetime But there is also a hypothesis that gravity is caused by gravitons, which are particles that can be imagined as an invisible line between two objects, and gravitons are the basic substances that make up the line. There are differences in the number and intensity of gravitons between different objects, which is why some celestial bodies cannot absorb light, but some celestial bodies can change the propagation path of light. However, humans have not found evidence to confirm the existence of gravitons. Whether it really exists is a mystery. Does the graviton existPlanck scale
The universe is so large that people can only use light years to express distance, so what is the smallest size of the universe? Of course, it is the Planck scale defined by Planck, the founder of quantum physics, and the Planck length, Planck time, Planck mass, etc. can be obtained by calculation. For example, the Planck length is 1.6x10^-33 cm. If matter is smaller than this size, then it cannot be observed. However, some scientists believe that this is not the smallest size, and that there is a value in the universe that is smaller than this value, but so far, no physicist has calculated it. If it is not now, it does not mean that it will not be in the future. The size of the universe is beyond the imagination of human beings, and the smallness of the universe cannot be easily defined. Measurable Matter in the UniverseConsciousness and Matter
Is there a consciousness in the universe? Humans belong to a part of the universe, then the universe is conscious, and consciousness is built on matter. This is what is called materialism in human philosophy. Consciousness cannot be created out of thin air, it must be built on the basis of matter. However, materialism does not exist alone, it has a lifelong enemy - idealism. Many people criticize idealism, believing that it hinders the progress of human beings, so it is easy for people to generate pride and arrogance that I am the center. However, there are many scientists in history who are supporters of idealism, such as Descartes, who created the coordinate system, he once said "I think, therefore I am". Descartes: I think so I am idealistic and did not hinder Descartes' academic achievements. Therefore, idealism believes that the universe is generated based on consciousness, and the sun and the earth all come from the consciousness of the universe. Whether it is idealism or materialism, they all have their own theories, but they also have certain limitations. In short, no one can convince anyone. According to materialism, the universe first had matter, then the will was born, and finally consciousness shaped the universe today. Idealism, on the other hand, believes that the universe first had a consciousness, then produced matter, and finally shaped the universe today. So, where did the first one come from? Created out of thin air? Eternal War - Materialism and IdealismMystery of the Big Bang
The universe came from a big bang, which seems to be the conclusion of the birth of the universe, however, the big bang The explosion is also a hypothesis, a hypothesis that is considered correct by the majority of the people. In essence, it is still a hypothesis, so how the universe came to be is still a mystery. Big bang theory believes that about 14 billion years ago, our universe was just a point, and finally one day, it exploded. The mass of this point is very large. According to the law of mass conservation, the mass of the point is equal to the mass of the universe today. The energy of the Big Bang explosion is converted into mass, but it is not a macroscopic celestial body, but a microscopic particle. After the explosion, hydrogen atoms were born in the universe, and it was from it that the familiar periodic table of elements was formed. The real celestial bodies, that is, the first stars and planets were born 100 million years after the explosion. The explosion also caused space to expand, the universe began to expand, and all matter in the universe was moving away from each other. However, the Big Bang Theory is not the only conjecture, and many scientists have other hypotheses. The birth of the first macroscopic celestial bodies such as astrophysicist Christopher Wittrick, who constructed a cosmic framework different from the big bang at Heidelberg University. He believes that the universe is not expanding, its mass has been increasing. As for where the extra mass comes from, other astronomers believe that the universe is connected to other spaces, and that there is material communication between the two. Unless human beings personally reach the center of the universe and archeology at the edge, the birth of the universe will always be dominated by hypotheses. In addition to the above assumptions, the multiverse also has a terrible conjecture under consideration-civilization created the universe. Simply put, when civilization develops to a certain level, it can create celestial bodies and gradually upgrade to the creation of the universe. From the creation of a star, to the creation of a star system, to the creation of the Milky Way, supergalaxies, etc., and finally to a universe. There is more than one universe, they are diverse, and the universe can increase or decrease. The higher the civilization level, the more it can determine the life and death of a universe. Who created the universe Generally speaking, the civilization that created the universe is the most advanced civilization. The earth, the sun, and even the universe where we are located all came from the creation of the higher civilization. When the higher civilization was created, the ending had already been designed, and we just walked step by step towards the set program. If this is the case, what exactly are time and space, and do they really exist? Or does it exist only in the created universe? These five unsolved mysteries may not be solved by human beings for a long time. Of course, the unsolved mysteries of the universe are not only these, but many more. Humans have a long way to explore the universe. Humans don’t even know the true size of the universe, because the current universe is only the reach of light.- Last：Poyang Lake and Dongting Lake shrink one after another: the lake has become a prairie, what signal is released here
