The universe and the microcosm cannot be juxtaposed, so they cannot be connected by the word "and".
Human beings, who call everything within our horizon events, the universe; In other words, everything we can see, observe, affect, and ** to is called the universe.
The division of the microcosm is only artificial, and human beings artificially divide our world into macrocosm and microcosm, just for the convenience of research, and have no other broader significance; Note that there is only one universe in our universe, and our universe only follows a unified set of scientific laws. It's just that we humans haven't found it yet.
You have to distinguish between the real meanings of these concepts, and read more books on the history of physics.

The human eye can distinguish objects with diameters larger than above, and things smaller than that scale belong to the microcosm. Matter is made up of a large number of particles – molecules, atoms, or ions – that are invisible to the naked eye. Molecules, on the other hand, are made up of smaller particles (atoms).
As for the atom, it is made up of nuclei and electrons. Molecules, atoms, nuclei, electrons are all very small. Tiny objects and phenomena that cannot be directly perceived by people's senses are usually called "microscopic objects" and "microscopic phenomena", respectively, and the totality of these objects and phenomena is called "microcosm".
The universe is made up of matter, and matter is made up of molecules.

The essential attribute of the microcosm is quantum, that is, discrete, discrete, and jumpy, which is embodied in "discontinuity", that is, "discontinuity". The orbital transitions of electrons, the collapse and relaxation of the wave function, and the spins of non-rigid bodies are all beyond imagination, and human beings have not really understood them, and there is no clear physical image.

The atom is the universe, what is the microcosm like?

The microcosm is a miniature world, it's mysterious, and you have to use special equipment to observe.

The universe originated from 100 million years ago, which has long been confirmed by modern cosmology, and the Hubble redshift and microwave background radiation are strong evidence to support the theory of the universe, but while we are studying the universe with an observable diameter of 93 billion light years, we are also studying the deepest secrets of matter, which is what we often call the microscopic world. Historically, we have tried to find the smallest component of matter, the five elements of gold, wood, water, fire and earth in ancient China and the four elements of earth, air, water and fire in the West are all preliminary explorations of the microscopic field, and later the ancient Greeks Leukeyb founded the atomic theory, believing that the atom is the smallest unit of matter, and a huge amount of atoms constitute everything in the world like building blocks. However, with the development of science, we have found the atom and then discovered the nucleus and extranuclear electrons that make up the atom, and also found protons and neutrons and the quarks that compose them in the nucleus, but the motion laws and states of these microscopic particles are completely different from those of the macroscopic world.
Quantum is not a single particle, but the sail is a collective term for all microscopic particles, most of these microscopic particles in the microscopic world present the uncertainty principle and wave-particle duality, which leads to the complete failure of the physical laws of the macroscopic world in the microscopic world, the uncertainty principle leads to the inability of us to obtain the microscopic particles at the same time to obtain the speed and position of the particles, and the wave-particle duality makes human observation affect the experimental results. At present, quantum mechanics is in charge of the microscopic world, and general relativity is in charge of the macrocosm, and these two sets of theories describe the same universe for us in different fields, but the experience of the microcosm cannot be used for macrocosm, and the experience of the macrocosm cannot be microcosm.
In the future, the universe may continue to expand until galaxies move away from each other. Of course, it is also possible to expand to a certain extent and then begin to shrink, turning into a singularity again, and then imitating the reincarnation of Tanci.

Looking at the boundless universe always makes people eager to go to school and learn about the process of the birth of the universe. Incredibly, the universe is a small miracle. With the advancement of science and technology, people are becoming more and more aware of the birth of the universe.
Recently, the universe has been discovered in the microcosm.
The universe may be a microcosm. After all, exploring the universe doesn't happen overnight. So far, humans have only landed on the Earth's moon, which is equivalent to opening a small window.
It is estimated that the solar system has been developing for hundreds of years, but the lack of human discoveries in the microcosm has been improving.
With the advent of high-end electron microscopy, the Atom Ling Chi is very similar to the current Jujube Solar System. You can see the cell magnified 1 billion times**. The sun is like the nucleus of an atom, and the planets in the solar system are electrons.
Of course, this phenomenon is found not only in the atoms of matter, but also in the cells of the human body. Therefore, there is an opinion that the universe is a microcosm and that the universe is a huge cell of life. I have to say, the idea is very imaginative.
Unfortunately, this is just a guess, unless humanity can now determine the boundaries of the universe. If rain and snow are a cell, then it has more time than humans. Why Do Cells Live So Long? These are all impossible to guess. The origin of the universe and the origin of humanity.
Currently, the scientific community observes in the microscopic world that the arrangement of electrons in the nucleus is very similar to that of the solar system, but this does not mean that all the atoms observed by scientists are living beings. The same goes for the nucleus in the oxygen atom, so the microscopic world and the cosmic galaxy are very normal and cannot represent anything. There are all sorts of strange galaxies in the universe.
I'm sure you've never seen such a miraculous phenomenon in the microcosm. After the origin of the universe, the earth began to be born after various coincidences, and then human beings evolved into wisdom without the universe.
With the lack of energy on the earth, exploring new energy has become the most important thing in the world. On the premise that humanity needs to have a ship to reach those places and gather from the resources that humanity needs. At this point, humanity will explore the entire galaxy.

The cosmology refers to the space-time view of matter, which holds that matter is the only master of the universe and the only entity that exists in the universe, and even space is relatively existing because of the existence of matter, so compared to the essence of material space is nothing, matter is a tangible form in a certain space, and the time is the measure of the existence of matter. Worldview refers to people's views and opinions about the world as a whole and the various world relations that exist in this world, and these views and opinions will vary depending on people's social status or different perspectives. These are the differences between the worldview and the Kuyubi cosmology, and the main difference is the way of understanding the world.

The universe generally refers to everything in objective space-time, and it is usually necessary to recognize the origin of objective space-time, that is, to discuss it under the premise of materialism. The world, on the other hand, contains everything subjective and objective, and the world view can be divided into materialism and idealism.
In everyday context, cosmology focuses on physical meaning, that is, the understanding of the universe; Worldview focuses on philosophical implications, that is, the perception of the world as a whole.
In order, the cosmology determines the worldview, and the worldview determines the outlook on life. If the cosmology is not correct, it is difficult to have the worldview correct. For example, in the Middle Ages in Europe, the earth was considered to be the center of the universe because people observed that everything revolves around the earth.
This led to the fact that the worldview of the people at that time was self-centered, and the indirect view of life was also wrong, believing that there was a God who ruled everything, and the dark and hungry Middle Ages came from this.

There are broad and narrow senses of the cosmology.
1. The broad cosmology and the worldview are the same extension, which refers to the fundamental view of the whole of all things.
2. The narrow view of the universe refers only to the view of the macrocosm.
This is to mention from the point of view of contemporary science, physics is, to put it bluntly, a discipline that studies the movement of matter and the underlying mechanism of matter. In his book The Mathematical Principles of Natural Philosophy, Newton gave precise definitions of several concepts. Among them, he gave this definition of "force": >>>More

1. Constipation:
In modern society, staying up all night and living an irregular life are common phenomena. Because there is no fixed pattern of normal people's bowel habits, there are large differences between individuals, and healthy people's bowel habits are mostly once or twice a day or once a day or two, and the stool is mostly formed or soft; A small number of healthy people have up to 3 bowel movements a day, or 1 time a day, and the stool is semi-formed or hard sausage-like stools. >>>More
Tracing the source, tracing the source, exploring the root and source of things; The earliest is the food safety management system gradually established and improved by the European Union in 1997 in response to the problem of "mad cow disease". This set of food safety management system is promoted by the first industry, covering the upstream and downstream of the entire food industry chain such as food production bases, food processing enterprises, and food terminal sales, and sharing information through special hardware equipment similar to bank ATM systems to serve end consumers. >>>More
First, the firing temperature is different.
The firing temperature of pottery is generally lower than that of porcelain, and the lowest even reaches below 800 and the highest can reach about 1100. The firing temperature of porcelain is relatively high, most of them are above 1200, and some even reach about 1400. >>>More
