Chapter 647: M Theory

As soon as the thought moved, Chu Hao suddenly said to the staff of the Swedish Academy of Sciences behind him: "I want to borrow a conference hall, is it okay, I have a new physical theory that I want to release." ”

The staff was stunned, they had never seen at the Nobel Prize ceremony, demanding the release of new physical theories.

However, in the face of Chu Hao, the new Nobel Prize winner, they did not dare to slack off, and hurried to ask the dean.

In the face of everything that happened on the stage, everyone was a little confused, not knowing what was going on, could this Oriental boy have some kind of moth.

Soon, Chu Hao got a permissive reply.

The staff announced that Chu Hao had a new theory to release, and everyone was dumbfounded.

They have experienced many Nobel Prize award ceremonies, but there is really no scientist who can be said to have released new physical theories at the Nobel Prize.

However, everyone's curiosity was immediately aroused by Chu Hao, and they wanted to know what important discoveries Chu Hao had that needed to be announced at the Nobel Prize.

Move, conference hall.

Because it was a temporary reason, Chu Hao didn't do any PPT, but chose the conference hall with a huge blackboard.

Coughing, Chu Hao opened his mouth and said, "Compared to everyone, everyone is no stranger to my Type E miscellaneous theory. ”

Everyone couldn't help but nodded, of course they are no strangers to E-type miscellaneous theories, and it can even be said that Chu Hao's E-type miscellaneous theories are the most famous arguments in the theoretical physics community in recent years, and any scientist who pays attention to cutting-edge physics should know the E-type miscellaneous theories.

However, hearing Chu Hao say this, the physical theory that Chu Hao is going to talk about next should be about theoretical physics, and everyone's eyes couldn't help but light up.

"I would now like to come up with a new theory, which I call the M theory, where M can stand for magic, or mystery, or even a membrane, or even a matrix, depending on your preference. ”

Chu Hao was on the blackboard and wrote, oh no, he drew a huge M.

"Theory M is the theory I propose as the ultimate theory of physics, and Theory M hopes to explain the nature and interaction of all matter and energy through a single theory. It combines five superstring theories and the theory of supergravity in 11-dimensional space. ”

Everyone's expressions changed instantly, Chu Hao is this going to unify physics and greatness.

Although superstring theory is known as the key to the unification of physics, it has never been perfected and has never been confirmed, and Chu Hao now seems to want to further evolve superstring theory into a more advanced theory.

"In the game of Go, there are only a few rules such as enclosing or not encircling, and with black and white chess pieces, you can play a kaleidoscopic variety of games. Similarly, modern science holds that the natural world is governed by a few rules, and that there are an infinite number of states and structures that these laws allow. Any force that has not yet been discovered will be extremely weak, or its effects will be strongly limited. These effects are either confined to extremely short distances or only work on extremely specific subjects. ”

"We used to be very confident that they had found all the forces and that nothing was missing. However, when it comes to describing the laws of these forces, they lack the same self-confidence. The two pillars of 20th-century science – quantum mechanics and general relativity – are incompatible. General relativity violates the rules of quantum mechanics at the microscopic scale, while black holes challenge the foundations of quantum mechanics itself on the other extreme scale. In the face of this dilemma, it is not so much that physics is no longer brilliant, but that it heralds a new revolution. ”

Salam and Weinberg's unified theory of weak electricity simplifies the two laws that describe electromagnetic force and weak force respectively into one law. The ultimate goal of M-theory is to describe all known forces (electromagnetic, weak, strong, gravitational) in a single law. The emergence of M theory is to make quantum mechanics and general relativity compatible in a new theoretical framework!"

Everyone's expressions gradually became nervous, but many people still remained skeptical, if the M theory was really so powerful, then the world would really be completely turned upside down.

"In supersymmetric physics, all particles have their own supersymmetric partner. They have exactly the same quantum number as the original particle (color, charge, baryon, lepton, etc.). The superpartner of the boson must be a fermion, and the superpartner of the fermion must be a boson. Although no definitive evidence of the existence of a supersymmetric partner has been found, theorists are convinced of its existence. They believe that because the supersymmetry is spontaneously broken, the mass of the superpartner particle must be much larger than that of the original particle, so it cannot be detected in existing accelerators. ”

"Local supersymmetry also provides a new way to incorporate gravity into the unified theory of physics. Einstein's theory of general relativity is derived according to certain requirements under the transformation of generalized space-time coordinates. Under the transformation of supersymmetric space-time coordinates, local supersymmetry predicts the existence of supergravity. In supergravitational theory, gravitational interactions are transmitted by a boson with a spin of 2 (graviton), and the superpartner of a graviton, a fermion with a spin of 3/2 (gravitrino), which transmits a short-range interaction. ”

"In the M theory system, time is divided into two kinds, one is time in our secular sense (i.e., time in the current universe for human beings). There is also a definition of imaginary time, which has no beginning and end, but always exists, and is a vectorless axis used to describe superstrings. ”

"Theory M believes that energy is not conserved in its own dimension, and energy will escape to other membranes in its own warping, and the strings are divided into open strings and closed strings, and the graviton string is different from the other three strings, which is a boson with a spin of 2, which is defined as a free closed string in the theory, and can be propagated to the high-dimensional space outside the cosmic membrane and other cosmic membranes, so the energy field escapes more in its own dimension, that is, the current universe. ”

"In theory M, there are countless parallels in the membranes, and the membranes interact and collide to produce four elementary particles, electromagnetic waves and species, which are the cause of the Big Bang. ”

Everyone couldn't help but gasp, if it was really what Chu Hao said, then there was no doubt that the M theory must exist.

"General relativity does not impose an upper limit on the dimensionality of space-time, and the theory of gravity can be established on any Villemannian manifold. The theory of supergravity, however, sets an upper limit on the space-time dimension – 11 dimensions. More intriguingly, it has been shown that 11 dimensions are not only the maximum allowable dimension of supergravity, but also the minimum dimension to include equidistant groups SU(3)×SU(2)×U(1). ”

"However, in the face of chirality, one of the pillars of the theory of gravity suddenly collapsed. Chirality2 is an important feature of nature, and many natural objects have a symmetry similar to that of a person's left and right hands. The spin of a neutrino, for example, is always left-handed. ”

"When other types of forces are absent, all systems that are subject to gravity collapse into black holes. The reason why the earth is not crushed by its own weight is that the material that makes it up is hard, and this hardness comes from electromagnetic force. Similarly, the reason why the sun did not collapse is only because of the tremendous outward force generated by the nuclear reactions inside the sun. If the Earth and the Sun lose these forces, they will shrink in just a few minutes, and they will shrink faster and faster. As they contract, the gravitational pull increases and the rate of contraction increases, engulfing them in the rising bend of space-time, turning them into black holes. Looking at the black hole from the outside, time there seems to have stopped, and no further changes will be seen. The black hole represents the ultimate equilibrium state of the gravitational system, which is equivalent to the maximum entropy. ”

Speaking of this, everyone fell into thinking, thinking about whether Chu Hao's M theory can really achieve self-consistency.

Chu Hao smiled slightly, he believed that the string must exist, and the M theory would definitely be established.

Because although the general quantum gravity is not yet understood, Hawking has successfully proposed an entropy formula for black holes using quantum theory. This fact is sometimes called the black hole paradox.

Hooft, a Dutch theoretical physicist who solved the problem of quantization of gauge fields in his twenties, once asked string scholars why string theory failed to solve the problem of black holes. At the time, it was not clear whether this was a challenge or an encouragement, but when string theory evolved into M theory, all doubts quickly dissipated. Hooft, a genius with a keen sense of physics, heard thunder when the rain was about to come, but he could not have foreseen what a storm was coming!

In some cases, the Dp embryo can be interpreted as a black hole, or more appropriately a black embryo, i.e. an object from which no matter, including light, can escape. Thus, the open string can be seen as a closed string with a part hidden in the black embryo. Black holes can be seen as being composed of black embryos in 7 compact dimensions, so the M theory will provide a way to solve the black hole paradox. Hawking believes that black holes are not completely black and that they can radiate energy. Black holes have entropy, which is the degree of disorder of a system, measured by the number of quantum states. Before M theory, people were helpless about how to count the number of quantum states of black holes.
