I don t know if it s right to think about a little idea of the Great Unification Theory, so please e

From the 20th century to the present, the first problem solved by the great unification of physics is how to make the four fundamental forces described in general relativity (gravity) and quantum mechanics not contradict each other at any scale. For example, when studying the singularity of a black hole, its mass is so large but the scale is very small, is it applicable to general relativity or quantum mechanics? This kind of question, if the landlord said that energy is the basic unit, how can the various elementary particles that make up the atom be represented?

The unification of these four fundamental forces should be inseparable from quantum mechanics. I didn't understand the entropy of what the landlord said. I'm just an amateur too.

All I know is that in addition to string theory, which is considered to be the theory of unified physics, there is indeed a theory called "theory of everything" (mine) that also aims to unify general relativity and quantum mechanics. The theory of all things has advanced in the unified theory of electroweak action, which unites the electromagnetic force and the weak nuclear force, and in the grand unified theory that unites all forces except gravity (I don't understand the specifics).

In addition, string theory is indeed one of the most amazing things, and understanding the 10-dimensional space it describes makes me feel that the general theory of relativity (including the big ** theory) in the 20th century is a prototype of string theory. It points out that there may be universes with different laws of physics, and that these universes are born from the collision of different initial conditions of the cosmic membrane in another dimension (large**), which means that each universe with different laws of physics must have its own set of physical theories that describe it.

The Great Unified Theory, referred to as GUT, also known as the principle of all things, because there are only four kinds of interaction forces between microscopic particles, gravitational force, electromagnetic force, strong interaction force, and weak interaction force, theoretically all phenomena in the universe can be explained by these four forces.

This theory originated from the study of electromagnetism, which Maxwell proved to be two aspects of the same fundamental interaction of electromagnetic phenomena and can be described by the same set of equations. By the middle of the 20th century, the description had been refined to include quantum mechanical effects and appeared in the form of quantum electrodynamics (QED).

There is a successful theory of strong action, quantum chromodynamics. It is an unbroken SU(3) normative theory. Therefore, since the mid-70s of the 20th century, it is natural to start a new exploration on the basis of the success of the unified gauge theory of electroweakness, with the goal of unifying the strong action and even the gravitational effect through the gauge principle and the electroweak action.

The so-called grand unity theory is an attempt to achieve the unity of the three interactions of strong, electromagnetic and weak according to the same concept and method of the electroweak unified theory (i.e., the gauge field plus the spontaneous symmetry break), but the normative group should be generalized to a larger simple group [such as su(5), so(10) or e(7)] containing subgroups su(3) su(2) u(1), etc.). According to this theory, the intensity of the various interactions varies with energy. As the energy increases, the strong effect gradually weakens, while the electroweak effect becomes stronger.

When the energy reaches about 1024 electron volts, the three action intensities become equal and unified into one canonical action (with the simple group as the canonical group). The Grand Unified Gauge Theory has an astonishing prediction that the proton is unstable and that it will decay into other particles, whose lifetime is estimated to be 1031 2 years. However, this prophecy has not been experimentally confirmed.

In addition, there are attempts to introduce supersymmetry (boson-fermion symmetry) into the grand unified theory, and try to solve some problems of the grand unified theory itself (such as the normative hierarchy problem). Supersymmetry, though, seems to cause more problems than it solves. There is also a discussion of the theory of super-unity (also known as extended supergravity), which attempts to use supersymmetry to unify gravity and the other three interactions at the same time at an energy of 1028 electron volts.

Recently, in search of new avenues, there has been a renewed interest in the unified field theory of high-dimensional space in Kalucha. Begin to seriously consider physical effects in dimensions other than the fourth dimension. There are also attempts to combine supersymmetry and high-dimensional space.

All these theoretical attempts to unify all four interactions are now very immature and fail to provide a realistic unified solution. Moreover, the quantum effects of gravity at such energies have begun to become important, and there is no satisfactory quantized theory of gravity so far. It can be seen that it is still quite far from the real realization of Einstein's grand vision.

In short, various levels of unified gauge field theory, including electroweak unification and grand unified gauge field theory, have been and will continue to be one of the central topics in theoretical physics. The ideal of a unified field theory will continue to inspire people to continue to explore the mysteries of nature in a deeper and more tenacious way.

Now, it has been found that there are only four interaction forces between microscopic particles, which are gravitational force, electromagnetic force, strong interaction force, and weak interaction force. All phenomena in the universe can be explained by these four forces. Further study of the connection and unity between the four forces, and find a theory that can unify and explain the four interaction forces, which is called the grand unity theory.

In his "A Brief History of Time", Hawking frankly said that there may be some people in the world today who will discover the grand unification theory in their lifetime. But this grand unified theory is not the grand unified theory that Einstein originally thought, and it is impossible to describe and ** everything in the universe through a simple and wonderful formula. Because the universe is unified with certainty and uncertainty, the uncertainty principle in quantum theory reflects uncertainty.

The scientist has not yet found it.

It unifies the theory of strong nuclear force, weak nuclear force, and electromagnetic force, referred to as the GUT grand unified theory.

I think the theory of great unification has overly complicated the analysis of experts, and they all believe that the Qin dynasty is the winner of the great unification, and the Qin dynasty has succeeded by using its resourcefulness.

Answer: Yes, because with the development of society, experts have more detailed and in-depth thinking about the theory of grand unification.

Not overly analyzed. The theory of great unification is a product of historical and cultural progress, and it has a certain research value.

The theory of unification may be discovered tomorrow, or it may never appear.

Let's first look at what is the basis of the theory of grand unification. The theory of great unification is, in fact, the theory of the complete unification of the four fundamental forces in the universe.

All the forces in the universe can be divided into – gravitational force, electromagnetic force, strong interaction force, weak interaction force.

The two pillars of modern physics, the theory of relativity and quantum mechanics, we need to pay attention to the following details:

When Einstein proposed the theory of relativity, the interaction between strong and weak forces had not yet been formally discovered. Electromagnetic forces, strong and weak interaction forces, are dominated by microscopic particles. In his later years, Einstein searched for a unified theory, and the goal was to unify gravity and electromagnetism, although Einstein did not succeed, and even if he succeeded, he lacked the unity of strong and weak interaction forces.

This begs the question: has humanity really found all the fundamental forces? Is there really only four fundamental forces in the universe?

Assuming that there are indeed only four fundamental forces in the universe, does the theory of great unification really exist?

At present, the key to the study of the theory of unification is to explore the essence of all things—to trace back to the source.

From this point of view, quantum mechanics seems to have unlimited prospects, and the quantum force field of quantum mechanics completes the unification of electromagnetic forces, strong and weak interaction forces.

It is a pity that gravitational mechanics cannot be unified, and even gravity cannot be explained using quantum mechanics.

The theory of relativity can easily use space to explain gravity, but unfortunately it does not complete the unification of electromagnetic force. Albert Einstein once tried to explain everything in terms of space, that is, everything is made up of space. The celestial bodies we see are only imaginary formations formed by the distortion of space, but they are not completed.

In pursuit of the theory of great unification, string theory was born from quantum mechanics and became a branch of physics.

String theory, using "energy" to explain everything, "energy strings" are the essence of all things, not microscopic particles, "energy strings" vibrate, rotation is different, constitute a variety of particles, photons, quarks, and then form all things in the universe.

However, string theory has not been confirmed by substantial experiments, and many physicists do not recognize that the basis of string theory is "ten-dimensional space", which is much beyond human cognition.

The history of the development of modern natural sciences is a science that studies the development process and laws of natural sciences. Based on historical facts, it summarizes the historical experience of scientific development and reveals its laws through the analysis of the historical process of scientific development. In the long history of the development of natural science, there have been three serious crises in modern times, and this has also brought about three major breakthroughs.
