Is there a contradiction between the universal conservation of nature and the cosmic non conservatio

Usually local non-conservation leads to deeper research and the discovery of more general conservation laws.

For example, the non-conservation of cosmic symmetry (i.e., the asymmetry of physics under the P-transform) led scientists to discover the CPT theorem (i.e., the symmetry of the laws of physics under the joint transformation of the CPT).

The law of non-conservation of universal symmetry states that in weak interactions, the motion of matter that is a mirror image of each other is asymmetrical.

Symmetry reflects the commonality of different forms of matter in motion, and the destruction of symmetry causes them to show their respective characteristics. The law of non-conservation of universal symmetry states that in weak interactions, the motion of matter that is a mirror image of each other is asymmetrical. This theorem was first proposed by Yang Chenning and Lee Tsung-dao, and later verified by Wu Chien-shiung with cobalt-60 experiments, and later became the cornerstone of the weak action theory in physics.

The law of non-conservation of symmetry has completely changed mankind's understanding of symmetry, which has contributed to the attention of the physics community in the following decades, and is of great significance in the study of particle physics and the improvement of the theory of the universe. In 1957, Yang Zhenning and Lee Tsung-dao both won the Nobel Prize.

The law of non-conservation of universal symmetry is illustrated by example:

Suppose there are two cars that mirror each other, and the driver of car A sits in the left front seat with the accelerator pedal near his right foot; And the driver of car B sits in the right front seat with the accelerator pedal near his left foot.

Now, the driver of car A starts the ignition key clockwise, starts the car, and presses the accelerator pedal with his right foot to make the car move forward at a certain speed; The driver of car B did exactly the same thing, just swapping left and right – he turned on the ignition key in an anti-clockwise direction and pressed the accelerator pedal with his left foot.

And keep the pedals leaning in line with A. Now, how will car B move?

Perhaps most people would think that two cars should move forward at exactly the same speed. Unfortunately, Wu's experiments proved that in the world of particles, car B will travel at completely different speeds, and the direction may not be the same! This is how the world of particles is incredibly illustrated by the non-conservation of cosmic symmetry.

1.The universe is not conserved, this is a word that is both familiar and unfamiliar to many Chinese, familiar, because this is the first Nobel Prize for Chinese around the world, and it is natural that our textbooks and ** will often mention this.

2.is unfamiliar because most people don't know what this cosmic non-conservation is talking about, except that Yang Zhenning and Lee Tsung-dao discovered it.

3.In addition, compared with a large number of confusing technical terms in cutting-edge theoretical physics, the five words of non-conservation of cosmic symmetry still seem very close to the people.

4.After all, we have learned about the conservation of energy and momentum in middle school, and we are still very familiar with the concept of conservation, and the cosmic symmetry should be related to some symmetry of the universe.

5.However, what exactly is the universal symmetry, why is it not conserved, and why the non-conservation of the universal symmetry will make the scientific community so shaken, so much so that Yang Zhenning and Li Zhengdao proposed in June 1956 that the cosmic symmetry is not conserved, and the cosmic symmetry does refer to a kind of symmetry, and if you want to understand why Yu Yeyu's non-conservation is so important, we must first understand why symmetry is so important.

In nature, the amount of loss that must be conserved is ().

a.Momentum. b.Energy.

c.Angular momentum Calendar.

d.All of the above is true.

The answer is d

Folk tales are one of the important categories in folk literature, and I will bring you a discovery of the law of non-conservation of universal symmetry, come and take a look.

In the words of scientists, the universe is the abbreviation of the inner universe. It is a physical quantity that characterizes the transforming properties of a particle or a system composed of particles under spatial reflection. Under the spatial reflection transformation, the field quantity of a particle changes only one phase factor, which is called the cosmic symmetry of the particle.

We can also simply understand that the cosmic scale is the image in the mirror when the particle looks in the mirror. In the past, people believed that the symmetry of the universe must be conserved based on the symmetry recognized in the physical world. It's like if there are positrons, there must be negative electrons.

In 1951, Professor Yang Chen-ning cooperated with Professor Tsung-Dao Lee, and in 1956, he jointly proposed the law of "non-conservation of cosmic symmetry in weak interactions".

It's actually quite simple. Symmetry reflects the commonality of the morphology of different materials in the motion, and the destruction of symmetry makes them show their respective characteristics. Like architecture and pattern, there is only symmetry without its destruction, and although it looks regular, it seems monotonous and rigid at the same time.

Only basically symmetrical but not completely symmetrical architecture and patterns constitute beauty. Nature is such an architect. When nature constructs large molecules such as DNA, it always follows the principle of replication, connecting the molecules together in a symmetrical helical structure, and the spatial arrangement that makes up the spiral structure is identical.

However, in the process of replication, the slight deviation from the exact symmetry will create new possibilities in the order of the macromolecular units, so that those styles that are easier to reproduce will develop more quickly, forming a developmental process. Therefore, the destruction of symmetry is the reason why things are constantly evolving, evolving, and becoming colorful.

The universe is not conserved.

It includes molecules, atoms, and elementary particles.

A fundamental practical meaning of physics.

The non-conservation of universal symmetry (even if only in weak interactions) is not a local theoretical development, it affects all aspects of the entire physics community.

Symmetry was important in the destruction of physics in the 20th century, especially the theory of relativity.

The great achievements in the space-time symmetry of Huaiqin are also quantum mechanics.

The extreme emphasis on symmetry made people's belief in and dependence on symmetry at that time no less than the dependence on absolute space-time before the 20th century.

The discovery of non-conservation of universal symmetry shattered belief in God's absolute symmetry and forced people to rethink the question of symmetry, a turn that led to many profound discoveries that followed. People are slowly discovering that although God likes symmetry, he does not like absolute symmetry, because absolute symmetry inevitably leads to the same for everyone.
