How did the universe come about? How did the universe come to be?

The universe is created due to the big **, the origin of the universe is an extremely complex issue, the universe is the material world, it 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.

One of the most influential theories in the modern cosmology, also known as the great ** cosmology. It illustrates more observational facts than other models of the universe. Its main idea is that our universe has evolved from hot to cold.

During this period, the cosmic system was not static, but was constantly expanding, causing the density of matter to evolve from dense to thin. This process from hot to cold, from dense to thin is like an explosion of great scale. According to the cosmological point of view of the big **, the whole process of the big ** is:

In the early days of the universe, temperatures were extremely high, above 10 billion degrees. The density of matter is also quite large, and the entire universe is in equilibrium. There are only some elementary particles in the universe, such as neutrons, protons, electrons, photons, and neutrinos.

But because the whole system is expanding, the temperature drops very quickly. When the temperature drops to about 1 billion degrees, the neutron begins to lose the conditions for its free existence, and it either decays or combines with protons to form elements such as heavy hydrogen and helium; It is from this period that chemical elements begin to form. After the temperature drops further to 1 million degrees, the early process of forming chemical elements ends (see Theory of Element Synthesis).

The matter in the universe is mainly protons, electrons, photons, and some relatively light nuclei. When the temperature drops to a few thousand degrees, the radiation decreases, and the universe is mainly gaseous matter, and the gas gradually condenses into gas clouds, and then further forms a variety of star systems, which become the universe we see today.

For the origin of the universe, scientists currently agree with the theory of the universe.

All the matter, space, and time in the universe are formed after the big **, with Einstein's famous mass-energy equation e mc2 finally confirmed, that is to say, energy can also be converted into matter under certain conditions. According to the mass equation, it is inferred that the static mass of an object will be reduced by releasing energy with the appropriate square usage.

It is even possible to release all the energy contained inside the object in an appropriate way. This means that the static mass corresponding to the energy of the object is completely lost, and the corresponding object ceases to exist.

The disappearance of the static mass becomes the energy of the field. The field has energy, and thus, the field has mass. Conversely, if there is no object in the space, the input energy can also produce an object!

The mass-energy equivalence relationship means that any form of energy has a corresponding mass. Any physical object that, under the right conditions, can convert the entire static mass into the energy of a field. Any form of energy can also be transformed into a physical object with static mass under the right conditions.

So, yes"Something out of nothing".Therefore, the big singularity is an intangible, infinitely small, and wonderful existence. It is not yet the universe, but it is the beginning and origin of our universe.

Although existing theories cannot describe what is at the singularity. But I guess there's infinite energy at the singularity.

I don't know why this big ** before the singularity will**, maybe God gave the singularity a prerequisite. This kind of ** is overall and orderly, involving all the material elements of the universe, time and space. ** As a result, the universe expands everywhere, and the temperature drops accordingly.

When the temperature drops to a certain level, fusion fission produces new elements, and the aggregation of material elements gradually forms superclusters, galaxy clusters, galaxies, and even stars and planets. Time and space also appeared.

We know that everything has a beginning and an end. Therefore, the ultimate destination of the universe after the big ** is not to continue to expand, but to eventually stop expanding and shrink in turn.

Rather, due to gravity, it will eventually stop expanding and shrink in turn, creating a small black hole, and then the black hole will merge with each other, and the entire universe will become a big black hole. Black holes gradually evaporate into elementary particles such as electrons and photons, as well as anti-elementary particles such as antielectrons. When they meet, they disappear into energy and photons (when a pair of positive and antiparticles meet, they will disappear at the same time and be completely converted into energy, this phenomenon is called annihilation), in this way, all the matter in the universe collapses and annihilates into energy, and then returns to the singularity before the big ** with infinite energy.

And that's the end of time. (Without "events," there would be no time.) )

Cycle.

How was the universe formed? No one knows the details. After studying the stars, the Milky Way and the universe, some different conjectures have been proposed, and one of the widely accepted conjectures is that the universe was formed after a big ** 15 billion years ago.

About 15 billion years ago, all the objects in the universe were gathered together, forming a heavy and hot fireball, this primitive fireball continued to expand, and one day suddenly a big **, the universe was born. ** In the next second, the temperature of the large fireball rose by 10 billion degrees Celsius, and it was crowded with countless examples, colliding with each other to produce various elements, and they slowly mixed together to make up everything in the world.

Many Westerners believe that the earth and sky were created by the supernatural 6,000 years ago (and many still believe in this conclusion, although in doing so their intellect looks the same as those who believe that the earth is flat). In any case, most scientists now accept the fact that the solar system was formed 4.6 billion years ago by a natural process of dust and gas clouds, and that these clouds may have existed since the universe was formed 15 billion years ago.

At the beginning of the universe, for the first 300,000 years after the birth of space-time, the universe was opaque. As protons and electrons combine to form atoms, radiation can pass freely, and an observable universe is formed.

But if we go back to the time of the big ** and assume that all the matter and energy of the universe is concentrated in a fairly dense ball, and this ball is very hot, and it happens** to form the universe, then where does this ball come from? How did it come to be? Do we have to assume that there was supernatural creation at this stage?

Not necessarily, scientists introduced a discipline called quantum mechanics in 1920, and it was so complex that we can't explain it here. This is a very successful theory, which properly explains phenomena that other theories cannot explain, and can also ** new phenomena, and ** new phenomena are exactly the same as what actually happens.

In 1980, an American physicist Alain. Guji began to use quantum mechanics to study the question of the origin of the Great **. We can assume that before the big ** happened, the universe was a huge glowing sea in which nothing existed.

Obviously, this description is inaccurate, these do not contain energy, so it is not a vacuum, because by definition there should be nothing in a vacuum. The pre-universe contained energy, but all of its components were similar to those of a vacuum, so it was called a false vacuum.

In this false vacuum, a tiny particle exists where there is energy, and it is formed by an aimless force that changes irregularly. In fact, we can think of this glowing false vacuum as a foamy bubble that can produce a small piece of existence here or there, like foam produced by ocean waves. Some of these beings soon vanished, returning to a false vacuum; And some, on the contrary, become very large or form an object like the universe after a large **.

We live in such a bubble of success.

But this model has a lot of problems, and scientists have been making up for and solving them. If they solve this problem, wouldn't we have a better perspective on where the universe came from?

Of course, if part of the Gusi theory is correct, we can simply go back and ask where the energy of the false vacuum came from in the first place. We can't say that, but it doesn't help us to prove the existence of the supernatural, because we can go back a step and ask where the supernatural matter came from.

The answer to this question is shocking, i.e. "it doesn't come from anywhere, it always exists that way".

The Formation of the Universe:In the beginning, matter could only exist in the form of elementary particles such as neutrons, protons, electrons, photons, and neutrinos. The continuous expansion of the universe after that caused the temperature and density to drop very quickly.

As the temperature decreases and cools, atoms, nuclei, and molecules are gradually formed, and they are compounded into the usual gas. The gas gradually coalesced into nebulae, which further formed a variety of stars and galaxies that eventually formed the universe we see today.

Universe:

The universe is the general term for all things, the unity of time and space. The universe is a material world, which exists objectively and does not depend on human will, and is in constant motion and development, with no beginning and no end in time, no boundary and no end in space. The universe is diverse and unified; diversity in the diversity of material manifestations; Unity lies in its materiality.

The universe is a unity of space, time, matter, and energy.

Another explanation of the universe: it is only a product of human vision and touch, and more fundamentally, it is a world of thinking, it is not a material world, it only depends on human will and objectively exists, it has no time and space, and there is no truth to prove its existence.

How did the universe come to be? It's a hard question to answer, someone.

It is said that it is generated by extremely high energy like the atomic nucleus, and it can also be said to be caused by the nuclear energy of the universe, and the energy of the extremely high nuclear energy is dispersed to form the universe, but we can only find this extremely high energy cosmic nuclear energy in the atomic nucleus, which is probably the same situation.

The relationship between the universe and the present tense of the universe is related to the fact that the thing gave birth to the universe, and this thing is the mother of the universe, and the universe is the flesh and blood of its mother, and the universe grew up eating its mother's milk. In that case, who is the Mother of the Universe? What is its name, the scientific community agrees that the singularity is the singularity, and the universe was born from the singularity.

The development of science to this day is no longer what it was like in 1927 when someone first proposed the Big Bang, what black holes, what dark matter, what antimatter, and what anti-universe in the universe have been created one after another, some have observed, and some use it.

The universe is anti-cosmic, and the universe is generated by the singularity in the anti-universe through **.

The anti-universe is a cold universe, and the universe goes from hot to cold to anti-universe, and the anti-universe generates the universe from extremely cold to extremely hot. The universe did not exist about 16 billion years ago, when there was only an anti-universe composed of antimatter.

Speaking of antimatter, although people can't see it now, they see the antiparticles of positrons and negative protons, which have opposite characteristics in the microparticles of the universe.

There are microparticles with opposite characteristics in the universe, so it can be imagined that the anti-universe formed by these anti-particles is the main thing, and this anti-universe gives birth to a cosmic singularity with extremely high energy to form a cosmic macro**. We humans know very little about the anti-universe now, and it is only a hypothesis that the anti-universe gives birth to the universe.

The universe is constantly releasing energy, but the anti-universe is absorbing energy, and when the anti-universe absorbs the cosmic energy, its stored energy will be re-released to give birth to a new universe.

The universe originated from the big **.

The so-called big ** theory, simply put, is that the universe was formed by a fireball ** at the beginning. Modern scientific research has found that the universe is not eternal, but constantly expanding. The imbalance of the universe was first discovered by a German doctor.

When he looked at the stars in the night sky, he found that the distances between the planets were not close to each other because of gravity. Then, there must be another force between the planets that cancels out the gravitational pull between them. He postulated this phenomenon as the continuous expansion of the universe.

Later, scientists discovered the phenomenon of redshift, that is, the light from distant planets to the earth is mostly red light, and the close ones are mainly purple light. This shows that the planet is moving away from the Earth. Then Einstein proposed the general theory of relativity, and he proposed the theory that acceleration is not equal to zero, which includes the theory of the expansion of the universe.

In 1931, American astronomers with advanced astronomical telescopes discovered that there are still many Milky Ways outside the Milky Way, and they are constantly expanding, which confirmed the theory of the expansion of the universe.

In the 40s, scientists **the universe was created by the large**, so there must be residual matter left in space after it**. The material left behind is the electron wave [radiation wave], which represents a temperature of about minus 273 degrees. This assumption was not proven at the time.

In the 60s, scientists at Bell Labs set up antennas for telecommunications research and found that they kept hearing noise, which represented a temperature of about -260 degrees Celsius. At the same time, physicists at Princeton University are also looking for the afterwave of the large ** based on the theory, and later the two groups of working studies jointly said that the noise received by the antenna is the afterwave of the large **, and its temperature is about minus 270 degrees, which confirms the theory of the large **.
