Modern science believes that human beings were born more than 2 million years ago, human beings evolved from ape creatures, in about 2 million years, apes lived on the earth, at that time there were many other ferocious creatures living on the earth, apes in order to be able to develop for a long time, so they chose to live in groups, so that not only can promote the opportunity to communicate with each other, but also can effectively resist foreign invaders, scientists have found that Frequent communication can make the ape's brain become more and more intelligent, because the ape creatures have been together for a long time, so the ape's brain has become more and more developed, and finally successfully evolved into humans, human beings as the most intelligent life on the earth, since the birth of the continuous research and exploration of the world's mysteries, now human beings have been able to go out of the earth to explore the universe, which shows that the speed of human science and technology development is very fast, the reason why human beings can have such a rapid development speed, is mainly inseparable from the contributions of scientists, such as Einstein.
Einstein is known as one of the greatest scientists of the 20th century, he is the only physicist comparable to Newton, his theory of relativity and the quantum hypothesis of light and other theories have an important role in physics, astronomy, engineering and other fields, he put forward the chivalrous theory of relativity and general relativity, overturned Descartes's view of time and space, completely changed the human perception of time and space, Descartes believes that time is the extension of things and the extension of motion of the comparison, existing in subjective thought, not something that really exists, It's just our way of thinking, about space, Descartes thinks that first we need to be clear about the nature of matter, and he believes that the essence of matter is not the elements of weight, color, and hardness, but things that have length, width, and height. Length, width, and height constitute a three-dimensional space, and there is no difference between all matter and space, and Descartes regarded objects simply as extensions of space, that is, extensions, so the extensibility of space is simple and cannot be analyzed.
Regarding the reality of space, Descartes was a staunch supporter of philosophers like Plato who believed that there was no such thing as a true void. For Descartes, the reality of space exists only when it describes the range of objects and matter. But the advent of a true mathematical coordinate system opens up new possibilities for a very different conception of space. This new idea is almost entirely due to Isaac Newton. He gave us a set of equations that seem to fully describe the motion of objects and how these motions are changed by the forces with which they interact. Newton himself insisted that space is absolute; It exists completely independently of any object within it. The empty volume implied by the Cartesian grid is itself an entity. According to Newton, time is also absolute. From Aristotle to Descartes, "time" is mostly understood as a count of events. But in Newton's view, there is a unified universal clock, and time is the same for all observers—even without any changes, time passes "on its own".
To put it simply, everyone's time is the same, no matter what kind of change occurs in the world, but the passage of time will not change, for hundreds of years, human beings have been following Newton's view of time and space, until Einstein appeared, only to break this traditional view, Einstein believes that the world is not the world we knew before, that is, time, speed, space, position and matter are specific objective facts, according to Einstein's theory of relativity we can know, Time and space are interconnected, this theory has changed human understanding of the physical world, and has also promoted many new scientific discoveries, Einstein's theory of time and space is also considered to be the driving force for the possibility of time travel, although Einstein himself never said that time travel is possible, but his theory of time and space provides a theoretical basis for time travel, which is one of the reasons why many scientists and physicists believe that time travel is possible.
Einstein believed that time actually does not exist, he is just a fantasy of human beings, time is not immutable, it will change with the speed of speed, for example, there is a pair of twin brothers, the elder brother drives a spaceship to leave the earth at sub-light speed, and the earth waits for the elder brother on the earth, so who is the elder brother or the younger brother who passes time faster? Because the speed is relative, relative to the elder brother, the earth is also flying at high speed, in the eyes of the elder brother, the younger brother's time has slowed down, and after a minute, the elder brother returns to the earth, the earth is still the same as it was, but the younger brother may have become old, this is because the speed of speed can affect the passage of time, you may see this, many people think it is incredible, but this is the case, in order to prove that Einstein's theory is right, scientists also did an atomic clock experiment, in 1971, Scientists have used high-precision atomic clocks to verify the slow clock effect in the theory of relativity.
Scientists put 4 atomic clocks on two planes respectively, and placed an atomic clock on the ground as a reference, the reason why scientists rotate the atomic clock is because its accuracy is very high, in tens of millions of years, the error is less than one second, the two planes fly to the east and west respectively, the plane flying to the east, because it flies in the direction of the earth's rotation, the speed relative to the ground is the speed of the plane itself plus the speed of the earth's rotation, and the plane flying to the west is flying against the direction of the earth's rotation, Therefore, the speed relative to the ground needs to be subtracted from the speed of the earth's rotation, and the final experiment shows that the time of the atomic clock of the aircraft flying eastward is 59 nanoseconds slower than that of the ground atomic clock, and the atomic clock flying west is 273 nanoseconds faster than the ground atomic clock.
That is to say, the closer the spacecraft travels to the speed of light, then the passage of time will be slower, when the spacecraft travels to the speed of light, time will stop, if the spacecraft can fly faster than the speed of light, then time will go backwards, but Einstein believes that the flight speed of any object with mass cannot exceed the speed of light, nor can it reach the speed of light, because a mass object travels at the speed of light, then its mass will become infinite, in our physics, There is no infinite amount of matter at all, so the spacecraft can get infinitely close to the speed of light, and cannot really reach the speed of light, time is not only affected by speed, but also by gravity, in simple terms, gravity is the force that attracts each other to any object with mass, on the earth, the gravitational force that we can feel is actually the gravitational force of the earth on us. Before Einstein, we thought that time and gravity had nothing to do with each other, but Einstein believed that there was a close connection between them.
In Einstein's general theory of relativity, there is a point of view: the mass of an object can bend the surrounding space-time, which means that the mass of the object can also affect time, and in a strong gravitational environment, time will pass very slowly, this phenomenon is called the time dilation effect, why does this happen? This is because the magnitude of gravity determines the degree of curvature of space-time, in a strong gravitational environment, space-time is seriously distorted, which means that the passage of time will be affected, but this phenomenon is almost not felt on the earth, after all, the mass of objects on the earth is too small for us to feel, but in the universe, there are many supermassive celestial bodies, such as black holes, the gravitational pull of black holes is very strong, which makes the surrounding space-time curvature abnormally large, so when time passes near the black hole, It can become extremely slow, or even stop completely. Albert Einstein gave us a new view of time and space, and gave mankind a new understanding of the universe.
Not only that, but Einstein's mass-energy equation also tells us how the sun burns, and the mass-energy equation is expressed as the energy (e) of matter equal to the product of the mass (m) of the mass of the matter and the square of the speed of light (c2). e=mc2 may be one of the simplest formulas you'll ever see, but it's so big that it can be described as "groundbreaking." Albert Einstein exposed the relationship between mass and energy for the first time, breaking the traditional perception of the conservation of mass. The mass-energy equation shows that mass and energy can be converted into each other. Mass and energy, these are two fundamental physical quantities that are extremely important. They were originally thought to be unrelated, but the genius Einstein directly equated them through the factor of the power of the speed of light, which is unbelievable. Before this equation was proposed, humans had no idea why the sun could burn for so long, and they didn't know what the burning principle of the sun was, but this formula gave the answer.
The combustion of the sun is a reaction of internal nuclear fusion, the sun is mainly composed of hydrogen and helium, of which hydrogen accounts for about 75 percent of the total mass of the sun, helium accounts for 20 percent, and the remaining 5 percent is composed of heavy elements, there is a very high pressure and temperature inside the sun, nuclear fusion reactions can only be produced under such extreme conditions, proton-proton chain nuclear fusion: nuclear fusion inside the sun is mainly achieved through proton-proton chain nuclear fusion. It is a series of successive nuclear reactions that involve the fusion of proton nuclei. Specifically, this process consists of the following steps: the first step: proton fusion, where two protons (protons) first meet and nuclear fusion occurs, forming a helium-2 nucleus (an isotope of helium), and the second step: helium-2 nucleus fusion, where a helium-2 nucleus collides with another proton to form a helium-3 nucleus. Step 3: Helium-3 nuclei fuse the helium-3 nuclei to further fuse, colliding one of the helium-3 nuclei with the other helium-3 nucleus to form a helium-4 nucleus. Step 4: Helium-4 nuclei fuse two helium-4 nuclei with each other to produce a helium-4 nucleus and two hydrogen nuclei. These two additional protons can continue the proton-proton chain nuclear fusion reaction.
Since the sun is a reaction of internal nuclear fusion, the life span of the sun is about 10 billion years, and up to now, our sun has burned for 5 billion years, and the life of the sun is about 5 billion years left, and the mass of the sun accounts for 99% of the total mass of the solar system in the solar system86, the remaining eight planets and other matter account for 0 percent of the total mass of the solar system14. From the proportion, we can see that the mass of the sun is very large, in the vast universe, the number of stars and planets is very large, our sun is only one of them, how many celestial bodies are there in the universe? At present, scientists are also actively studying, many scientists believe that the number of celestial bodies in the universe may be more than the sand on the earth, Einstein's greatness is not only that he proposed the theory of relativity, but also predicted many unknown phenomena. Black holes, for example, were proposed by scientists very early.
At that time, Einstein used the theory of relativity to calculate the existence of black holes, but due to the backwardness of human science and technology at that time, many people did not believe in the existence of black holes, and later in 2019, scientists observed the first black hole, which also proved that black holes do exist in the universe, and according to Einstein's theory, human beings also discovered gravitational waves, gravitational waves refer to the ripples in the curvature of space-time in the form of waves that propagate outward from the radiation source and carry energy. Gravitational waves are ubiquitous in the universe, but they can only be observed if they are emitted by high-speed masses or very massive objects, such as binary star systems, neutron star rotation or merger, supernova explosions, the formation of black holes, or the collision of two black holes. On October 16, 2017, scientists from many countries around the world held a press conference simultaneously, announcing that human beings had directly detected gravitational waves from the merger of binary neutron stars for the first time. Einstein's theory of relativity and quantum mechanics are now the two pillars of science.
We can see the greatness of Einstein from all kinds of signs, but why is it that such a great physicist studied theology in his later years? And when Einstein was in the hospital in his later years, he also wrote a memoir, which roughly means that God exists in our universe, God created our universe and controls everything about us, why did Einstein believe in God? Many people may think that theology is what we call feudal superstition, but theology in reality, it will never be opposed to science, and it is not the object of scientific suppression, their essence is the same, and there is also a certain philosophy, Einstein thinks that God may be different from the God we think, Einstein is a staunch atheist, he once said: "Religion is nothing more than the embodiment of ignorance", in this case, why will Einstein study theology be circulated in later generations?
In fact, many stories are made up, nothing more than to use the huge influence of Newton and Einstein to achieve a certain purpose, there are some anecdotal allusions about them that can be easily refuted, such as Newton's identity, he has lived in a **religious family since he was a child, his parents are **Christians, and it is not very strange that Newton is a **Catholic, but this does not affect Newton to study science with a scientific attitude, otherwise he would not have achieved such a huge scientific achievement. And the God in Einstein's "God doesn't roll the dice" is not the real God, but the truth of the universe, which has been misinterpreted by the outside world as the God of the religious world, and "the end of science is theology"? Einstein said he never said that. Einstein was also very confused in his later years, as the saying goes, the ignorant are fearless, a scientist like Einstein, the more mysteries of the universe he wants to explore, but it is impossible to solve all the mysteries of the universe by relying on his own strength.
And in the universe, there are a lot of very mysterious phenomena, and how does it all work? In fact, neither Einstein nor Newton explained clearly, for example, that celestial bodies are affected by gravity in the universe in addition to gravity? Is it also affected by other forces, why are the celestial bodies in the universe moving regularly, is it just because of gravity? And how did the light appear? Why is the speed of light about 300,000 kilometers per second, and who sets this speed limit? What's out of the universe? Perhaps there is a larger cosmic space outside the universe, some scientists believe that our universe may be derived from other universes, and other universes may also be branches derived from our universe, the theory of parallel universes, there are many theories in the scientific community, some people believe that black holes may be the entrance to parallel universes, after all, black holes can always devour matter, and these devoured substances go**?
Some scientists speculate that the matter swallowed by the black hole may go to another universe, and there is also a mysterious celestial white hole in another universe, and the black hole and the white hole are connected together to form a wormhole, if humans can enter the wormhole, maybe we can enter another parallel universe, but now scientists have not found wormholes in the universe, this is just a scientist's guess, the current human understanding of the universe is only the tip of the iceberg, and there are many mysteries hidden in the universe that we don't know. From the movement of celestial bodies to the expansion of the universe, from the expansion of the universe to the parallel universe, from the parallel universe to the dimensional space, the world we know is very shallow, and the universe is very profound from any point of view, and a drop of water we usually see is also a microscopic universe, no matter how huge the celestial body is, it is composed of tiny particles. The different arrangements of these particles make up the world as we see it.
It's incredible to think about it, because science can't explain too much, so many scientists believe that God exists, and this God is not a god, but the order of all creation, the once famous physicist Professor Yang Zhenning was asked in an interview: Do you believe that there is a God in this world? Yang Zhenning replied: If your so-called God is in the shape of a person, then I don't think there is, if you ask me if there is a creator, then I think there is, because our universe is not accidental. What exactly is this Creator? Now scientists are also actively researching and exploring, in order to explain the mysteries that human beings can not solve now, scientists have proposed string theory, superstring theory is an exploration in the field of physical theory, it is built on a series of complex and profound assumptions, these assumptions are designed to break through the limitations faced by the Standard Model, so as to reveal the more fundamental structure of nature, the core assumptions and basic principles of superstring theory lie in its unique interpretation of the construction and operation of the real world.
One of the key assumptions in the construction of superstring theory involves the basic composition of microscopic particles, which asserts that all matter and forces in nature originate from tiny string-like entities, rather than point-like particles as in traditional particle physics. These strings exhibit different particle properties through different vibrational modes, and this interpretation of vibrations provides a new way to describe the structure of matter in theory. String theory believes that everything in the universe is composed of the most basic strings, strings keep vibrating, can form a variety of particles, different vibrations of strings can be divided into two forms, one is an open string, the other is like a line segment, string theory believes that the graviton that propagates gravity is composed of closed strings, and the different vibrations of strings constitute different particles, these particles are composed of different substances, and different substances constitute everything in our world, so scientists believe that the most basic unit in the universe is the string.
Although human beings have not been able to solve this mystery at present, there is a certain truth in what scientists have guessed, and human beings want to solve this mystery, and the current level of human science and technology is completely unattainable, after all, the level of human science and technology is currently only 0Level 7 civilization, human beings can't even fly out of the solar system, let alone solve the ultimate mystery of the universe, so human beings still need to continue to work hard, thinking that human beings, as the most intelligent life on the earth, have only been a few million years since the birth of human beings, and the real start of human civilization is only a few thousand years, and they can go out of the earth to explore the universe in just a few thousand years, which shows that the speed of human science and technology development is very fast, although human beings are still unable to solve all the mysteries in the universe, But human beings as the most intelligent life on the earth, human science and technology is still developing, as long as human beings can make unremitting efforts, with the progress of human science and technology in the future, human beings will be able to solve the mysteries of the universe, in this regard, everyone thinks, how did our universe come about?
