Why does there exist?

There are a lot of universes, parallel universes.

For example, when you are in the bath, there are many bubbles in the bathtub, and one bubble represents a universe, a lot, but it does exist.

Now there is a hypothesis that black holes are the beginning of the universe.

14 billion years ago, there was no universe, there was only an energy point with infinite energy, for some reason, this energy point began to release energy (that is, the universe **), after the release, the energy began to coalesce to form matter.

There are too many coincidences in the universe we live in, like the charge of electrons, the slightest deviation of the electrons will fall into the nucleus, and the stars will not be able to burn. So I support three theories: first, the creation theory, that these coincidences may have been intentional by some wisdom (not necessarily a human-looking God); The second is the parallel universe, since it was not created, it may really be just a coincidence, there may be other universes outside the universe we live in, but the universe we live in just meets the conditions we need for survival, but it is too difficult to produce a universe that meets the conditions we need for survival, and the quadrillion universe may not be able to pick one (oh!).

That's not good); The third is the principle of human existence, the reason why the universe is like this is because we see it like this (this is a bit difficult to explain, it is too troublesome to call yourself on your mobile phone). As for how the universe came into being, I believe Hawking's statement that no matter why the universe exists, it is always born from a big ** and a singularity (a black hole is also a singularity). Finally, thank you.

Because the universe is inherent, the Tao is natural, the source is the original, the self is inconsistent, the essence is infinite, and the vitality is eternal.

So there is the main reason for the universe.

Why does the universe exist? It's not because humans exist that the universe exists. In fact, the universe existed before human beings existed, and existence did not exist only because of our human beings.

Existence itself is not in "causality", existence is reasonable! The existence of the universe means the meaning of reality!

The universe is a stable and balanced energy system, there should be "positive" matter and "anti" matter, the positive and anti matter energy is equal, and the total energy is 0According to the principle of lowest energy, there is gravity between the "positive" matter, and there is also a gravitational force between the "anti" matter, and the positive and antimatter should be repulsive between them, but annihilation occurs when they are close. So the universe should be in the shape of a figure 8.

Half is the "positive" universe and the other half is the "anti" universe. Suppose our universe is a "positive" universe and the other universe is an "anti" universe. The center of the universe in the shape of an "8" is called the "singularity".

There are two vibrations and two rotations in the figure-8" universe. The so-called ordinary matter is the cosmic energy that can be detected by human beings using electromagnetic waves, and dark matter is the cosmic energy that cannot be detected by human electromagnetic waves. The most abundant amount of dark energy is similar to "cosmic background radiation".

From the composition ratio, it can be seen that the visible matter is the least, the dark matter is the second, and the dark energy is the most.

The generally understood universe refers to a continuous system of space-time and space that exists in human beings, including all matter, energy, and time in between. The overall explanation of this system constitutes cosmology.

In ancient China, there was a saying that "the upper and lower four directions are called the universe, and the past and the present are called the universe", and the word universe also comes from "next to the sun and the moon, and the universe".

In recent centuries, scientists have established modern scientific theories about the universe based on modern physics and astronomy, called physical cosmology.

The universe is roughly made up of ordinary matter, dark matter, and dark energy.

Scientifically speaking, it is the great ** that produces the universe; From philosophy, you must first understand what "nothing" is, that there is something out of nothing, and that everything is from nothing; Theologically, God created the universe, but it is not said who created God. This can actually be answered from the traversal text or the Xiuzhen text: as long as you can traverse, you are God.

There are no answers to these kinds of questions, and many of them have not been proven, so we can't always think about these headache questions, facing the sea, and the spring flowers are blooming.

These are God's powerful creations and deeds.

You are too profound, such a question is suitable for a scientific journal.

The big ** model believes that the original universe was an ultra-high-temperature, high-density "point". About 18 billion years ago, this "point" suddenly **, only 10-36 seconds, accompanied by the supercooling phenomenon of vacuum phase transfer, this "point" expanded by dozens of orders of magnitude in an instant, becoming a one-centimeter-scale universe.

After that, the universe continued to expand, and the temperature began to drop from billions of degrees Celsius, and at about 55 million degrees Celsius, neutrons and protons were generated from the energy of the cooling process, which in turn merged into atomic nuclei, and these processes took only 3 minutes. About 300,000 years later, when the temperature of the universe drops to 3,000 degrees Celsius, free electrons are captured by the nucleus to form atoms. For about 30 million years that followed, those atoms continued to expand outward.

The universe also continued to cool, and by the time the cosmic temperature dropped to 167 degrees above absolute zero, atoms began to coalesce to form thin gases. Since then, it has evolved into new celestial bodies due to density fluctuations and gravitational effects. After more than 10 billion years, it has shown a variety of material forms, and has become the universe today.

Since the cosmic grand 15 billion years ago, stars and galaxies have been scattering outward. In fact, the expansion is accelerating. Steinhardt of Princeton University in the United States said that the universe has no beginning and no end, and the universe will never stop and happen again and again.

This is the universe.

The universe is infinitely large, with no borders, and therefore no inside or outside.

In fact, there is no answer to this, the big ** can't be fully explained, the big ** itself also has doubts, scientists also think that the universe is edged, and it is constantly expanding, and it is a parallel universe opposite to us outside the universe, but I personally think these views are a bit far-fetched.

For the question itself, it is recommended to read three books by Stephen Hawking, but still no concrete answer will be found.

The question goes far beyond astronomy and astrophysics, and may remain a mystery thousands of years from now. This question has risen to the level of philosophy, and materialist atheists cannot answer it.

This is an unsolvable question, and "A Brief History of Time" is recommended

Hehe, any question, a thing to break the casserole to ask the end is unsolvable, whether you ask about the tangible existence or the intangible existence "such as the invisible real existence, heart, honor, fear, beauty, love, affection, etc.", such a question will make life feel extremely frightened and afraid, and even collapse, but when life is true, good, and beautiful, that feeling is enough to eliminate the question you asked, and you will nod deep in your heart The meaning and value of existence. Perhaps few people in the world can experience the feeling of extreme peace and happiness in the soul when there is a kind of light when death, and the feeling that gives you the most beautiful moment of love is the same as the feeling I described, it is a feeling of eternal life, and all troubles, fears, and doubts can give you an answer without words.

I hope it can help you a little, I know the pain of life in the pursuit of these questions, but the pain is also good, at least you are pursuing the truth, but this path is extremely dangerous.

1. The universe 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 mass and energy of all the things 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.

The big ** caused the material of the reed brigade branch to scatter in all directions, the space of the universe continued to expand, and the temperature also dropped accordingly, and later all the galaxies, stars, planets and even life in the universe appeared one after another.
