How the earliest universe came out in BC

According to the current mainstream theory of the origin of the universe, it is simply as follows:

The universe was originally formed by a singularity with infinite density, infinite energy, and infinitely small volume**, and then space, time, and energy, some of which formed the basic elements of matter in a specific environment - hydrogen, helium, etc. These elements come together to form stars. After billions of years, nuclear fusion inside the star has led to the emergence of new elements of these simple elements under the action of nuclear fusion.

The combination of different elements has led to the emergence of many new substances. This happens when some stars are coming to an end**. The star fragments are generally some heavier substances, they are scattered into the universe, and when they enter the gravitational field of the star, they will slowly correct their orbit around the star according to the gravitational force and become a planet.

Gradually, after more than 15 billion years, the rich and diverse cosmic space we have now slowly formed.

Of course, this is just a relatively reliable assertion that many people firmly believe, but there are also many people who question it. Because there are many arguments in this theory that have not been verified by actual observations, or that cannot be verified by observations at all. But in any case, this is the closest thing to a correct theory of the universe that mankind has described so far.

Computers can now simulate wind tunnel tests, can simulate nuclear **, and in the future, they can also simulate the evolution of the earth and the creation of the universe. Therefore, it is very likely that our universe is simulated by another intelligence in his notebook, who can modify the passage of time and the laws of physics at will, and he is what many people call - God.

Ambition is nothing but a slave to memory, born with vigor but difficult to grow.

A long time ago, there was a big black hole in the universe, and the product of ** was the sun, the debris was a planet, and the black hole turned into a small black hole again and continued to expand.

This question is very, very difficult, and the current professional scientific statements are all nonsense out of thin air.

The big ** came out.

The origin and evolution of the universe begins with an understanding of the universe, which is a general term for the vast space and the various celestial bodies and diffuse matter that exist in it. The origin of the universe is an extremely complex issue. The universe is the material world, which is in constant motion and development.

For thousands of years, scientists have been searching for when and how the universe came to be. To this day, many scientists believe that the universe was formed by a big ** that occurred about 13.7 billion years ago. The matter and energy in the universe are gathered together, and condensed into a very small volume, the temperature is extremely high, the density is extremely high, and the huge pressure is generated in an instant, and then a large ** occurs, and the reaction principle of the big ** is called quantum physics by physicists.

The big ** caused the matter to be scattered, the cosmic space continued to expand, and the temperature also dropped accordingly, and then appeared in all galaxies, stars, planets and even life in the universe one after another.

Before the universe began to expand, unmeasurable particles (dark matter, dark energy) moved freely to form a chaotic state of the material world. This chaotic matter is not composed of atoms, particles, ions, etc., but is composed of lower levels of matter. According to the knowledge about matter recognized by modern science, it should be what is now called dark matter, dark energy.

At that time, the universe was an indivisible whole (as Pangu had when the heavens and the earth were opened), with no rotating particles, no magnetism and no electricity, and was in a state of free and disordered motion. The forces of the free movement are in direct opposition to gravity. The existence of gravitation is a constraint on the whole universe, and its function is to make the whole universe converge and concentrate, to contract and be silent; The activities of the forces of the free movement need a space for movement, and it forms a direct confrontation with gravity.

The opposing forces are evenly matched, so the entire universe is in a state of general equilibrium. In fact, even though the universe at this time is an indivisible chaotic whole, with uneven distribution of matter, there are great differences between tight and sparse, and there are multiple levels of free movement of multiple forces.

It starts with the origin of the universe. The universe originated from the universe, 13.8 billion years ago, there was a point that existed and did not exist, a point with infinite mass, infinite density, and high temperature, which is the singularity we are familiar with. The singularity cannot be calculated by modern physical formulas, and all physical laws are invalid at the singularity, and this magical singularity occurred 13.8 billion years ago** and expanded rapidly in a very short time.

How fast? For example, the universe expanded from the size of a hydrogen atom to the size of a baseball in less than a trillionth of a second, and from the size of a golf ball to the size of the Earth in less than a billionth of a billionth of a second! The universe during this period was in a state of "inflation".

In an instant, a large amount of energy and matter erupted, and it expanded outward at an astonishing speed.

In the ** process, a large amount of energy and matter is ejected from the singularity, and after the "inflationary" universe cools down rapidly, the particles in space begin to synthesize, first quarks condense into protons and neutrons, and then protons and neutrons come together to form atomic nuclei. The first ones to be produced in the universe were hydrogen nuclei and helium nuclei. The universe at this time was a state of high-temperature chaos full of energy and particles.

Quarks synthesize protons and neutrons.

After 380,000 years, electrons were added to form atoms, still mainly hydrogen and helium. The universe during this period gradually cooled down and began to become orderly.

After 400 million years, under the influence of gravity, hydrogen began to clump together to form primitive stars and galaxies. The universe of this period can be said to be the prototype of the modern universe.

Later, after more than 13 billion years of evolution, the universe became what it is now. If you were to illustrate this process in a diagram, it would look like this:

To sum up, the evolution process of the universe is roughly as follows: singularity** - high-temperature inflation - high-temperature chaos - cooling and order - primitive galaxy - modern universe.

How did the universe come to be?

The universe was born 13.7 billion years ago.

The universe was formed by a great ** that occurred about 13.7 billion years ago; And all the matter and energy in the universe are gathered together and condensed into a very small volume, and the temperature is extremely high. The universe refers to matter and space-time; Moreover, the mainstream view in modern cosmology is that the origin of the universe originated from a large **, which evolved from a state of extremely dense and extremely high temperature in the past, and reached a state through continuous expansion, which is called the grand theory of the universe or the theory of singularity.

The original source of the universe is a singularity, the so-called "cosmic egg", which condenses all the mass energy of space-time and gives birth to everything in the future material world, including celestial bodies and life. About 15 billion years ago, the cosmic egg suddenly exploded in an unparalleled large**. The big ** shocked out of time and space, the material world broke out of the shell, and the era of cosmic history began.

In the newly born universe, space grew from nothing and skyrocketed, and after only 10-32 seconds, it exploded to a diameter of about 1 light-year. In 1 second, the universe becomes a furnace of 10 billion k, and all matter is boiled into a pot of elementary particles.

Immediately afterward, a raging primordial cosmic storm began, with a violent collision between the elementary grains, which melted into the protons to form helium nuclei. This process continues for about three minutes until all neutrons are depleted. About 22% of the mass of the material is polymerized into helium nuclei, and the rest of the material is almost non-polymerized protons, that is, hydrogen nuclei, and only a few parts per 100,000 belong to the isotopes helium-3 and deuterium, and a few parts per billion belong to lithium.

The cycle goes on and on, and the matter is not extinguished!

If you go back 10 99 years, it's a hollow, you can't see anything, you can't touch anything. If you push back the clock by 10 99 years, you see no different from the previous ones.

The question is still unsettled ... Some say nothing, some say it's another universe...
