City in the Sky, the pinnacle of civilization, and the center of a huge laboratory, Zhou Xing leads scientists to engage in various scientific research day after day, perfecting the theory of the universe and studying interstellar weapons... Under their promotion, the scientific and technological fields of human civilization continue to advance. moves forward.
The huge command screen is divided into dozens of small screens. There is a major experiment in progress on each small screen, and Zhou Xing and a group of experts and professors are watching them remotely. Once something unexpected happens in the experiment, or there is a breakthrough. They will be informed of the progress as soon as possible.
"President Zhou, the 'Biaco Ball Cup' has reached its limit, and the experiment in this direction can be ended." Lin Hai walked to the chairman's seat and watched Zhou Xing report to him.
"Well, let's end it then!" Zhou Xing glanced at the experimental area of "Biaak Ball Cup", turned to Professor Lin Hai, and asked with concern: "Did you encounter a tricky problem?"
After saying that, Zhou Xing temporarily stopped the research project in his hands. If nothing unexpected happened, everyone would perform their duties, and Lin Hai would not come to him for no reason.
"Yes, Mr. Zhou, the super-light speed project has been realized, so the 'tachyon' hypothesis should be established. However, our research in this area has made little progress!" Lin Hai looked at Zhou Xing with a wry smile and said helplessly. .
When scientific research goes deep into a certain field, you will find that there are more and more difficult problems that will continue to trouble them. For example, after confirming the existence of "curvature" space, the problem of "tachyons" immediately surfaced. .
"Tachyon" corresponds to "tachyon", and scientists have already proposed this concept in the 20th century.
In the microscopic world, particles such as protons and neutrons that are bound by strong interactions are called hadrons. According to their own weight, they are baryons, and electrons are leptons. However, whether they are protons or neutrons, hadrons or baryons, they are all bradyons.
Among the sixty-one elementary particles predicted by the Standard Model, all particles except photons are bradyons. Their moving speed can only reach below the speed of light, and can be infinitely close to the speed of light but cannot exceed it.
In this universe, a stationary substance has the smallest energy. When it obtains energy, it begins to move. The more energy it obtains, the faster it moves. Until it obtains infinite energy, the speed of objects also reaches the limit, but they have speed. The upper limit is the speed of light. Their moving speed cannot exceed the speed of light, so they are called bradyons.
With the exception of photons, these particles all have a mass above zero, that is, their mass is positive. In fact, regardless of whether matter or antimatter, their masses are positive. The criterion for distinguishing between matter and antimatter is only the difference in charge.
Tachyon is a brand-new particle. The biggest difference from positive-mass particles is that its mass is negative. Therefore, its speed is always fixed at the speed of light. If energy is given to bradyons, the speed of bradyons will increase. On the contrary, if energy is given to tachyons, the speed of tachyons will slow down. The more energy given, the slower the tachyons are.
Like bradyons, tachyons also have a speed limit. The lower speed limit of tachyons is the speed of light. That is to say, the moving speed of tachyons is always faster than the speed of light. It can only be infinitely close to the speed of light, but cannot drop below the speed of light.
Because this characteristic of tachyons exceeds the speed of light, it cannot be directly observed, because humans live in the world of bradyons, just like black holes. They cannot be directly observed, but they can be observed through some kind of tachyon. effect, indirectly inferring its existence.
Hearing this, Zhou Xing frowned. The "tachyon" problem, like the dark energy of the universe, is a relatively advanced technology.
Tachyons are also divided into many different types. The mass of tachyons is negative. The matter composed of tachyons is negative matter. Tachyons have many very wonderful physical properties. Because its speed is always above the speed of light, it cannot be directly observed. Because its mass is negative, it can annihilate each other with all positive matter in a broad sense and return to nothingness.
One kilogram of negative matter can react with one kilogram of positive matter or antimatter. The reaction process is that the two disappear together and lose their traces from the universe. Moreover, during this process, no energy is emitted. Does not emit any radiation.
The law of conservation of mass and energy fails within the small area involved in tachyons, but is still conserved on the scale of the entire universe. If the "tachyon" hypothesis is introduced, then the ongoing construction of the universe model should almost be completed. !
Zhou Xing's eyes lit up, and he quickly brought up the holographic screen, tapping the keyboard with both hands, combining the "tachyon" hypothesis, various particle theories, and universe theories, arranging and comparing them.
Zhou Xing suddenly looked at the big screen and told Zhou Xiaozhi: "Xiaozhi, establish a 'tachyon' research project, integrating the unified theory of the universe, antimatter, negative matter, dark matter, and the tree system theory of the universe. According to the data I listed Models deduce models of the real universe.”
"Okay, boss." Zhou Xiaozhi responded. Immediately, Zhou Xiaozhi's computing power of tens of trillions per second was running wildly, combining numerous universe theories, corresponding to each other, and various theoretical data to deduce a real universe model.
The universe is composed of huge superclusters of galaxies. The galaxies are surrounded by large invisible empty spaces. Each galaxy contains billions of stars. The matter that makes up these stars is particles that are too small to be seen. Protons, neutrons and electrons are the most common particles, usually bound together in the form of atoms. Protons and neutrons are made of smaller particles called quarks.
The universe is governed by four forces or the interactions between them. These four forces are gravity, electromagnetic force, strong nuclear force and weak interaction force. These forces are brought about by a group of particles called gauges. Bosons, which are exchanged between the particles that make up matter.
Under the "universal rule", all forces including gravity, electromagnetism, strong nuclear force, and weak interaction force are related to each other, and it is pointed out that all subatomic particles may be produced by a kind of elementary particle...
…
Time flies, various theories and various data streams pour out on the holographic big screen.
The scientific and technological knowledge obtained from transactions with alien civilizations, human civilization's exploration of the universe, and Zhou Xing's research results in the field of the universe... were gathered together like a hodgepodge, and with Zhou Xiaozhi's huge computing power, he went all out to deduce and establish the original real universe model.
Time passed bit by bit, and all the scientists in the hall stared at the big screen, their faces filled with nervousness.
This cosmic deduction comes too suddenly. Artificial intelligence absorbs human knowledge in the field of the universe. Once the deduction is successful, it will completely unveil the mystery of the universe for mankind.
According to the Big Bang theory, the most influential theory in modern cosmology, the temperature was very high at the beginning of the universe. As the universe expanded, the temperature began to decrease, and neutrons, protons, and electrons were produced. After that, these basic particles formed various elements. These material particles attracted and merged with each other to form larger and larger clumps. These clumps gradually evolved into galaxies, stars, planets, and even appeared on individual celestial bodies. life phenomena.
However, there are still many unknowns in the universe, and what the real universe is like has not yet been determined.
Human beings have various speculations about the universe: multiverse: there are many parallel universes with different physical properties, and we exist in a universe suitable for life; absurd universe: the universe just happened to be like this; unique universe: some kind of deep hidden universe Physical coordination makes the universe what it is.
Principle of life: Some deep principle forces the universe to evolve in a direction that can produce life; Self-evident universe: An explanatory closure or causal loop: "Perhaps only a universe that allows consciousness can exist."; Divine creation universe: God of the universe The universe is intentionally designed to be a product capable of producing complex life; virtual universe: humans live in a virtual reality simulation world...
Can the powerful artificial intelligence Zhou Xiaozhi deduce a true universe model for humans? All scientists looked at the big holographic screen expectantly, full of expectations.
One hour passed, two hours passed... the data flow on the big screen still stopped.
"Mr. Zhou, this problem is too complicated. I'm afraid Xiaozhi won't have any results in a short time!" Lin Hai reminded Zhou Xing while looking at him.
"Well, this time to support the Galactic Alliance, we must obtain knowledge of the basic theories of the universe from them to supplement our knowledge structure."
"This issue has been reported to the Federation. Those guys from the Galaxy Alliance are also the ones who don't let go of the eagle. For the time being, let's rely on ourselves first!"
"The theory of the cosmic explosion, the tree of the multi-dimensional universe, the unification of particles, the theory of space-time energy... Can these theories really be combined? I'm really looking forward to it!"
“…”
After waiting for the results for a long time, the scientists stared at the large holographic screen, discussing excitedly in groups of twos and threes, and their emotions were extremely high.
Zhou Xing nodded, silently closed his eyes slightly, and looked at the system task panel.
"SSS main mission: the real universe, mission completion conditions: successfully learn the operating rules of the universe, mission reward: special reward (one copy), mission deadline: none, mission failure penalty: none."
(Task prompt: Host, you have successfully been promoted to an intermediate great scientist. Human civilization has entered the interstellar era. However, human civilization still has little understanding of the universe. Please use your abilities to explore the real universe.)
Since there is no deadline for the task, more than a hundred years have passed before I knew it, but the system task has not been completed. After such a long period of accumulation, it is almost time for a breakthrough!
"Mr. Zhou, look, look at the big screen. Xiaozhi has perfectly integrated the multi-verse tree and the theory of space-time energy! Now only the unified theory is left." Professor Lin Hai's excited voice suddenly sounded in Zhou Xing's ear rang out.
"It looks like it's almost done!" Zhou Xing opened his eyes and couldn't help but smile.
"Yes! The Multiverse Tree is the most complicated. If you hadn't personally verified this theory, who would have known that such a side of the universe existed!" Lin Hai looked at Zhou Xing with admiration and said with emotion.
"It's a mistake! It's a pity that the ultimate goal has not been achieved!" A trace of loneliness flashed across Zhou Xing's face and he sighed.
More than a hundred years have passed, and Discovery has already reached a scale of tens of billions. Although the specific situation of the "Exploration Center" is not known, there are still countless Discovery probes searching for traces of the Rock in the "Tree of the Universe". However, it seems that It’s like looking for a needle in a haystack. To this day, there is no news about the Panshi.
Seeing the look on Zhou Xing's face, Professor Lin Hai understood something. He immediately changed the subject and asked: "Mr. Zhou, if the universe model can be established this time, will dark matter surface?"
"Well, we definitely can't escape. Even if this deduction is unsuccessful, dark matter will be the focus of our next research." Zhou Xing nodded and said firmly.
So far, humans have discovered three types of matter in the universe, namely positive matter, antimatter, and dark matter.
Positive matter is the matter we usually see, and antimatter is an extension of antiparticles. As we all know, inside an atom, electrons carry negative charges and have a spin quantum number of positive half, while antielectrons are just the opposite. Carrying a positive charge, the spin quantum number is negative one-half. Not only electrons, neutrons, protons, etc. have their own antiparticles, matter composed of particles is positive matter, and matter composed of antiparticles is naturally antimatter.
Positive matter and antimatter have been widely promoted and applied in human civilization, but only the field of dark matter has not been able to achieve major breakthroughs.
The universe is like a huge "cosmic web", with entangled filaments connecting galaxies together. This entanglement is composed of baryons, which are subatomic particles composed of three quarks and three antiquarks. The anti-baryons are a type of hadrons. However, baryons are composite particles, not elementary particles. The protons and neutrons that make up the nuclei of everyday matter are actually baryons. Together with anti-protons and anti-neutrons, they are called nucleons. .
In the gaps of this "cosmic web", a large amount of dark matter that is so subtle that it is invisible is densely packed in it, playing an unknown role. Since dark matter does not absorb and radiate electromagnetic waves, it is electrically neutral. Dark matter has a small density and is difficult to capture. Therefore, human civilization’s research on dark matter has always been in a pioneering state.
Zhou Xing glanced at the big screen and added: "The research direction of dark matter starts with axions."
Axions are one-dimensional real particles of energy-efficient mass. Axion particles are new particles of polarized magnetic flux carrying "positrons". Axion particles can also be understood as "magnetic monopole particles". The mass of axions is approximately between 10＾-6 and 10＾-2eV. The color charge has no electric charge and has a spin of 0, so it is a boson, but its supersymmetric partner is a fermion.
Professor Lin Hai nodded in understanding. The properties of axions are very likely to be the basic particles of dark matter. Research in this direction should be fruitful.
However, if Zhou Xiaozhi combines many basic theories to deduce a true model of the universe, it will be a huge help to the study of dark matter.
Professor Lin Hai and the other scientists glanced at the big screen, waiting for the results of Zhou Xiaozhi's deduction.
