Speaking of this, the Red Lotus Divine Power took out the metal in the space ring, and immediately, a piece of iron was sucked into the lightning in his right hand: "Why? Because electricity produces a magnetic field, for this reason, those scientists used mathematical language and four equations to explain these two forces, and finally formed a unified electromagnetic force." ”

"This achievement is of great significance, all phenomena related to electromagnetism can be expressed by four simple equations, which is another step forward for human beings on earth to understand the mysteries of the universe, just like Newton's theory of gravity, which unifies many phenomena together. Albert Einstein considered it one of the most brilliant moments in physics and greatly admired the work of Maxwell, who unified the electromagnetic force. ”

About fifty years after the unification of electromagnetic forces, Einstein was confident that if he could integrate the new theory of gravity with electromagnetic forces, he would have a master equation that would depict everything, and indeed the entire universe. Albert Einstein firmly believed that the universe runs in a common and wonderful pattern that is higher than one qiē. The reason why he delved into the unified field theory is very simple, he wants to explore the laws of all things, unify the one qiē that human beings on earth know, from the birth of the universe to the magnificent vortex of the Milky Way, with one principle, one main equation, including one qiē. ”

Newton united the heavens and the earth with gravity, Maxwell had unified electricity and magnetism, and Einstein was thinking about the rest of the thing, trying to find the truth of all things, a simple theory that can include the law of all things in the universe, that is, the unity of the new theory of gravity and the electromagnetic force. ”

"Did he succeed?" said to the scientific giant. The demon giants couldn't help but feel a sense of admiration in their hearts, and they achieved such an achievement as mortals. It's hard to imagine.

Red Lotus shook her head: "When he started researching, he found that there were far more differences than similarities between the two. At the time, gravity was generally considered to be a very powerful force, after all, it was the force that allowed living beings to stand on the earth. However, if a person falls from a height, he will not fall into the core of the earth for the simple reason that it is because of the electromagnetic force. ”

"All objects, including us, are made up of particles called atoms, each of which has a negative charge on its surface. Therefore, if the atoms in that person's body collide with the atoms on the ground, the force of mutual repulsion of the charges is very strong, which is why he can only fall to the ground and cannot penetrate the earth's core. It is the electromagnetic force of a small place that can resist the gravitational pull of the entire earth and prevent the person from continuing to fall. In fact, the electromagnetic force is more than 100 million times stronger than the gravitational force. ”

"It sounds a little incredible, after all, gravity can make humans stand and the earth can revolve around the sun. But actually. Only between the behemoths can the gravitational force be felt. But at the atomic level, what is an atom, let's say that each of us is an atom. Even if tens of billions of people line up side by side in a straight line, the length is less than a meter, which is the basic particle that is inseparable in a chemical reaction. You can only divide it again in physical form, can you understand that?"

"Yes. Understood, you say. We're not stupid, we understand. ”

"Knowing that, we go on to say that gravity is a very weak force at the atomic level, and for Einstein it was a very difficult battle to integrate two very different forces, and worse, he turned a deaf ear to the drastic changes in the physical world. He is outdated. He made it all the way to middle age, and of course he wanted to continue to complete this theory and achieve greater scientific achievements, but he failed. ”

"During this period, there were many talented people in the scientific community, and Einstein's world-renowned achievements were no longer suitable for that era, and his halo was taken away by a group of young scientists. It's a peculiar new theory that completely upends Einstein's call for unity, led by a scientist named Bohr, who once again led the universe into a new realm. ”

"The atom, which at the time was thought to be the smallest particle in nature, turned out to be composed of smaller particles, protons and neutrons forming the nucleus, and the outer periphery was the orbital motion of electrons. Well, you see, you can think of this as the internal structure of an atom. At the time, neither Einstein nor Maxwell's theories could explain the behavior of these tiny particles, as well as the interactions within atoms. ”

Looking at the enlarged version of the internal structure of the atom in Red Lotus's hand, the demon giants kept nodding and watching intently.

"With the research of countless scientists, all kinds of theories about atoms have flown out, and the gravitational effect here seems to be negligible, and the electromagnetic phenomenon is not significant. With no single theory to explain this new world, scientists were lost in the unfamiliar territory of the atom, desperate to find a way out and struggling to find a way out, until a new theory called "quantum mechanics" appeared at the beginning of the twentieth century of the Earth calendar. ”

"This theory can explain the behavior of particles in the microscopic realm, but there is also a problem here, this theory is a very radical theory that completely shatters the previous understanding of the universe. Einstein's theory that the universe is ordered and predictable, but Bohr did not, declaring that at the atomic level, it was a random world. There is uncertainty at the atomic or quantum level. ”

"The best we can do is predict the probability of outcome after outcome again and again, according to quantum theory, a strange theory that at the time painted a disturbing new world for humans on Earth. If quantum theory were everywhere in our lives, many humans would think they were crazy. The laws of the quantum world are very different from what people used to do, and they are completely two completely different worlds, just like us who travel through to other civilizations, where people will think that we are strange. ”

"The quantum world is crazy, but it does prove that this phenomenon exists in the microcosm at the time. For example, we live in a quantum world, and I want a spell cheatbook, but this is a world of chance, and I may get a martial art, a biography, a novel, a pharmacopoeia, and so on. Quantum mechanics argues that different events do occur in a real universe parallel to us and for their respective occupants, just as we live in now. And from this derives a theory called the multiverse. ”

"Assuming that there are a thousand possibilities for an event, quantum mechanics cannot determine which one will happen, so all possibilities will be realized. This theory was rejected by many at the time, who thought it was too absurd. However, whether this theory is right or wrong has not yet formed a unified statement. ”

Einstein firmly believed that the world works according to predictable laws, and he firmly resisted the idea that we could only calculate the probability of events occurring. Quantum mechanics believes that you can't determine the outcome of any event, you can only determine the probability of an event, and Einstein firmly resisted this. However, one by one, the reality proves that Einstein was wrong. Quantum mechanics can indeed describe the workings of the universe at the subatomic level. To get the people of earth to know what they can't see with their own eyes, they can only rely on quantum mechanics. ”

"Quantum mechanics is seamless, and the assumptions it makes never diverge from real-world observations. In the subsequent research, when scientists observed the structure of the atom, they found two forces that support the world, one is the strong nuclear force, which bonds protons and neutrons together, and the other is the weak nuclear force, which converts neutrons into protons and produces radiation in the process. ”

"In the quantum world, gravity, as it is known, is completely overshadowed by electromagnetic forces and the newly discovered forces. Although the strength and weakness of nuclear forces may seem so insignificant, humanity on Earth demonstrated their toughness, and when the first atomic bomb exploded, it changed the course of history. In this explosion, scientists released a strong nuclear force, the force that tightly binds protons and neutrons to form atomic nuclei, and through guò to destroy this bond, splitting the atoms, and the incredible destructive force was released. ”

During the commentary, Red Lotus bounced a small fireball in her hand out, and suddenly, a mushroom cloud rose from the dark nebula in front of them, although it was so weak compared to the countless boulders next to it, its power should not be underestimated.

"The other force is radiation, which takes a long time to dissipate, and for ordinary people, this radiation reaches a certain amount, which is enough to kill people. So, while the range of the strong and weak nuclear forces for electromagnetic and gravitational forces is very, very small, the impact it extends can be significant. ”

But the question arises again, just as Einstein did against Newton at that time, how can gravity and his general theory of relativity find a place in the quantum world? Quantum mechanics tells people how the various forces of nature in the microscopic world work, except that gravity is not mentioned. In fact, this is because no one has been able to explain exactly how gravity works at the atomic and subatomic levels, which means that no one has unified general relativity and quantum mechanics together. ”

"Decades on, every attempt to apply the methods of quantum mechanics to the description of gravity has failed. The probability that scientists get in their research is infinite, which is simply meaningless, not because it means how profound it is, but because it is meaningless. The two are incompatible, and they have never been able to unify ......" (to be continued......
