Millions of years ago, mankind was born, and tens of thousands of years ago, human civilization was born. Hundreds of years ago, after continuous efforts and development, human civilization finally entered the road of technological development. The advent of the age of science and technology has also allowed human civilization to achieve inferior leaps, and finally ushered in an era of rapid development, making human civilization the current technological civilization.
Mankind’s achievements in science and technology in just a few hundred years have surpassed the achievements of the past tens of thousands of years of civilization. Why can human technology develop so fast? One of the important reasons is that it is inseparable from the advanced scientific theories of some great scientists. We all understand that the rapid development of science and technology requires the efforts and dedication of scientists.
But if scientists only study the existing, understandable and acceptable scientific theories step by step, then human civilization will not have the glorious achievements it has now. Only when scientists continue to put forward some scientific theories that exceed existing cognition, and put forward some scientific conjectures about the sky and horses, can we continue to work hard to verify these conjectures, so as to achieve a rapid technological leap.
This may be the greatness of human civilization. Scientific exploration and research requires dare to think, dare to guess. If you do not dare to guess or ask questions, then the speed of human science and technology development will inevitably be very slow. It is also impossible to realize the dream of flying to the sky in just a hundred years or so, stepping out of the earth and beginning to explore the universe.
During the development of human science, scientists have put forward many bold advanced scientific conjectures, many of which have been confirmed. For example, black holes, gravitational waves, space distortions, etc., most of these proven scientific theories can be accepted by people, but there are three peculiar scientific theories that have been proven, but they are difficult for people to accept. Why?
The first scientific theory that is difficult for people to accept is the mysterious superposition state. I believe that many friends know quantum mechanics, which is the greatest scientific exploration and research direction of mankind in the 21st century. We all know that this world is divided into macro and micro. The things we can directly see and observe are macro, but behind these macro things are micro worlds.
The nature of macroscopic things often requires finding answers in the micro world. Some things that are difficult to explain in the macro world can be seen very clearly and can be easily deciphered in the micro world. For example, when the temperature rises and falls, it is difficult for us to understand the nature of change in the macroscopic world, but when we walk into the microscopic world, we see the thermal motion of molecules. Only at this time we understand that the essence of temperature changes is the thermal motion of molecules.
Quantum mechanics is a great science and an important research direction for mankind in the future. Only by entering the world of quantum mechanics can we have a more detailed understanding of this world. When scientists discovered the world of quantum mechanics, they tried to apply various scientific theories from the macroscopic world to quantum mechanics, but the final result surprised us. It turns out that many things in the microscopic world are beyond our cognition and completely subvert the macroscopic world. Physical theory.
One of the mysterious superposition states is the case. The superposition state, or superposition state, refers to the state obtained after the normalized linear combination of several quantum states of a quantum system. The simple understanding is that two events that cannot exist at the same time in the macro world may exist at the same time in the quantum world, such as life and death.
I believe many friends know that in the macro world, many things can only show one formation at the same time, such as life and death. When we are still alive, the state of death cannot appear. Another example is left and right. When we stand on the left, the state of standing on the right at the same time cannot appear. This situation is very consistent with scientific theory in the macro world, and is a correct scientific view.
But in quantum mechanics, we see incredible superposition states, two things in different states can exist at the same time, for example, life and death can exist at the same time. This scientific theory has been confirmed by scientists, but it makes it difficult for people to accept it. The existence of superposition also reminds many people of parallel worlds, parallel universes.
The so-called parallel world means that our world is composed of countless similar worlds. Each world is a parallel world, and there is also you in different parallel worlds, but the destiny will be different. In this parallel world, you may be just an ordinary office worker, but in another parallel world, you may be a rich second-generation, driving a luxury car, carrying beautiful women, and living a life like a fairy. Can you accept this difference?
The second theory that is difficult for people to accept is the tunneling effect. This theory is also a magical phenomenon in quantum mechanics that has been confirmed by passengers. I believe that many friends expect that they have a magical ability to pass through walls. The editor remembers that there is one. Science fiction movies describe such a magical superpower.
Of course, we all know that things like crossing a wall are just a fantasy, and it cannot happen in reality. Therefore, many people think that the probability that humans can cross the wall is zero, which is something that will never happen. Is this really true? If we walked into the microscopic world and walked into the field of quantum mechanics, you might not think so.
There is a tunneling effect in quantum mechanics, which is actually a kind of wall penetration ability of particles. Through a large number of experiments, scientists have confirmed that particles can pass through walls, and macroscopic things are also composed of elementary particles. For example, from a microscopic point of view, people also have a large number of microscopic particles. Since particles can pass through walls, there is a certain probability that the human body can pass through walls.
Seeing this, many friends may be excited again. Since it is confirmed that the probability of a human body passing through a wall is not zero, then I will try to succeed. If you do this, you may never achieve it. Why? The reason is that the probability of a human body passing through a wall is so low that it can be ignored.
Although this is a non-zero probability event, if you want to truly realize it, you may need to wait hundreds of millions of billions of times before there is hope. Of course, we should not be discouraged. Even if we know that the probability of a human body passing through a wall is not zero, then with the continuous advancement of human science and technology, our understanding of quantum mechanics continues to improve. In the future, we may be able to develop a special equipment that will allow us to pass through walls as easily as particles.
The third theory that is difficult for people to accept is the limit theory of the speed of light. I believe many friends are aware of Einstein’s theory of relativity. According to the theory of relativity, the limit speed of an object is the speed of light. This is because as the speed of an object increases, the energy required is also In continuous improvement, when a mass object is infinitely close to the speed of light, the energy required is also infinite.
Even for a photon with a mass of basically zero, its speed is only the speed of light. So is this light speed limit theory correct? Scientists through a large number of experiments, such as building a more powerful particle accelerator, can only increase the speed to 99.99999% by accelerating electrons. No matter how hard they work, they cannot reach the speed of light.
These experimental data tell us that the light speed limit theory is correct. When this result came out, many people could not accept that if the speed of an object was limited to the speed of light, then humans would never be able to get out of the galaxy and never explore the entire universe. Are human scientific and technological efforts still meaningful?
Indeed, if the speed of an object is limited to the speed of light, then we are really powerless in the face of the vast universe. We can only observe the distant starry sky through astronomical telescopes, and we have to face the fact that the universe is accelerating and expanding. As time goes by, galaxies will move away quickly, and there will be fewer and fewer galaxies we can observe. , And finally see nothing. The earth has completely become a lonely existence.
Seeing this, many people may feel desperate, so is the speed of light really unable to break through? The theory of relativity closes the speed of light but also opens up another channel for us, that is, the theory of space-time distortion. The theory of relativity tells us that time and space can be distorted, and the speed of light can only be limited to a stable time and space. If time and space are severely distorted, the theory of light speed limitation will naturally be broken. At that time, we can surpass the speed of light and explore more. The distant starry sky.
