What is the Grand Unified Theory??? Is the Grand Unification Theory Really Viable?

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.

In physics, force is the oldest, simplest, and most esoteric concept. This concept of physics with the fewest strokes sounds like almost everyone understands, but physicists have been tormented by it for thousands of years.

What is the reason why objects on the earth, regardless of shape and size, always end up obediently falling to the ground? What is the reason why the earth revolves around the sun and the moon revolves around the earth in the sky? After painstaking thinking and research, scientist Isaac Newton found a unified theory - gravitation.

Whether it is an object on the earth or a celestial body in the sky, their motion can be explained by gravitational attraction. People have summed up the theory of heat and the theory of electromagnetic field about electromagnetic phenomena, and the contents of each part of physics are to summarize the laws and theories of various forms of motion. Whether these laws can be summarized and explained more broadly has always been a concern for physicists.

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.

After Einstein proposed the theory of relativity, he devoted himself to finding a unified theory to explain all interactions, that is, all physical phenomena, from the 20s until his death in 1955. His decades of unsuccessful efforts have inspired future generations.

In the 60s, Glashow, Weinberg, Salam three scientists put forward the unified theory of weak electricity, the weak interaction and electromagnetic interaction unified, this unified theory can explain the weak interaction and electromagnetic interaction of various phenomena respectively, and predicted several new particles, they won the 1979 Nobel Prize in Physics, in 1983 the experiment discovered the predicted particles in the theory, further proved the correctness of the theory.

In the mid-70s, people further put forward the theory of the unification of the three roles of strength, weakness, and electromagnetism. One of the conclusions of the Grand Unified Theory is that it predicts that protons will decay, which contradicts the experimental results. Although the grand unification theory has not yet succeeded, the research work to find the unity of the four interactions will not be interrupted, and people are still climbing this peak.

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 theory of grand unification has little impact on humanity. The principle of the universe is very simple, and we humans have complicated this originally simple theory. Because, the so-called grand unification theory, first of all, reflects only a person's ideological intention and subjective desire about physics; As for what or how the content of the real theory of grand unification is, no one may know.

Moreover, we also believe that this is the most basic ideological understanding of the problem of the theory of grand unification; Without this most basic ideological understanding, all the basic understanding of the theory of great unification will be divorced from reality. Therefore, the exploration of the grand unification theory may only be that people are following their feelings, and the true face of things is far from being understood.

The Grand Unified Theory, abbreviated as GUT, is also known as the principle of all things, because there are only four 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. By further studying the relationship and unity between the four forces, the theory or model that can explain the four interaction forces in a unified way is called the grand unity theory.

The grand unification theory has not yet been conclusively verified, and Hawking also pointed out in "A Brief History of Time" that the grand unification theory may be found. But this grand unified theory is not the grand unified theory that Einstein originally thought, because it is impossible to describe and ** everything in the universe through a simple and wonderful formula, after all, the universe is the unity of certainty and uncertainty.
