Did the heavens and the earth form before the universe was born?

The so-called heaven and earth should refer to space and the material world. The celestial bodies we think of are infinitely large, and there is never the largest, so there is no such thing as a true heaven and earth. Heaven and earth are the ancients to distinguish the world between the upper and lower, the ancients were very mysterious to the natural world, they didn't know that we were living on the earth, they only knew that there was a god above, the sky was high, the sky couldn't see the head, the earth didn't know how thick it was, it was unfathomable.

Many myths such as heaven and earth, wind and rain, thunder and lightning, dragon kings, and Hades have been formed. After modern science discovered the earth and the solar system, we realized that the sky is very big and very high, and it is a huge universe outside the earth. In this way, heaven and earth are only the primary perceptual understanding of the universe of the ancients, and they have seen some of the surface of the universe, of course, the limitations of knowledge, and they have not yet seen the true face of the universe.

We only know more than the ancients now, and have we seen the true face of the universe? Scientists estimate that our universe was born 15 billion years ago, but the earth as the earth was born 4.5 billion years ago, that is, when the universe was born, the sky had already been born, according to the opposing and unified view, there is no so-called heaven, and if the heaven and earth were born at the same time, it should be 4.5 billion years ago. It can be seen that before the birth of the universe, there was no heaven and earth.

It was only 4.5 billion years after the birth of the universe that the so-called heaven and earth were formed.

A model of the universe. The heavens are huge, the earth is small, and the earth is nothing compared to the heavens as a matter of dust. Humans are dust inside dust.

There is no essential connection between the universe and heaven and earth.

When we talk about heaven and earth, heaven is worth the sky, and the earth refers to nature as the earth.

However, the universe is infinite, and there are countless planets, and there is a saying that the universe is a singularity with infinite mass and infinitesimal volume before the big **.

At a certain moment, ** happened, and then the universe was formed.

The emergence of the earth was about 4.6 billion years ago, and it was not in the same period as the formation of the universe.

These questions arise when humans first look up at the sky and see the vast expanse of the sky and the sparkling stars. As for the origin of the universe, human beings have been constantly exploring. There are several hypotheses.

The first hypothesis is the "cosmic eternalism". This hypothesis holds that the space-time of the universe is infinite, that time and space in the universe are infinite, and that the universe is infinite and eternally existent. That is to say, the universe is infinite in space, and the universe has no beginning or end in time.

There is no beginning and no end to the universe. The universe is stable on a global scale, and even if it changes, it is only a local change.

The second hypothesis is the "cosmic stratification theory", which holds that the structure of the universe is hierarchical, with stars at one level, star collections forming galaxies, several galaxies combining together to form galaxy clusters, and some galaxy clusters forming supergalaxies to become a higher level.

The third hypothesis is the "universe greatness" theory, which many scientists agree with so far. It all started in 1929 when astronomer Hubble made a discovery that shocked the scientific community. This finding largely led to the conclusion that:

All extragalactic galaxies are moving away from us. That is, the universe is expanding at a high speed.

This discovery prompted some astronomers to think that since the universe is expanding, there could be a starting point for expansion. Belgian physicist Georges Lemaître believed that the present universe was made up of a "primordial atom"**.

This is the predecessor of the big ** theory. The Russian-American astronomer Gamov and the Soviet physicist Alexander Friedman accepted and developed Lemaître's ideas, and in 1948 formally proposed the Great ** theory of the origin of the universe.

Scientists who hold this theory believe that about 20 billion years ago, the material of the celestial bodies we see today was concentrated to form a primordial fireball with an extremely dense temperature of up to 10 billion degrees. Stars and galaxies did not exist at this time. Later, for some unknown reason, this primordial fireball became larger, and the materials that made up the fireball were erupted in all directions, and gradually cooled down, and the density began to decrease.

**After this occurs, the nucleus of heavy elements is formed. About 10,000 years later, hydrogen atoms and helium atoms were produced. During these 10,000 years, the matter scattered in space condensed into nebulae and galaxies.

Most of the gas became stars during the development of nebulae, and due to the gravitational pull of the stars, some of the matter became an interstellar medium.

But so far, there is no unified theory of the origin of the universe, waiting for further investigation and research.

Big ** Theory:

In 1927, the Belgian astronomer Lemaître proposed that the matter and energy of the universe were originally contained in a "cosmic egg", and that today's universe is the result of this unstable "cosmic egg"**. In 1929, after the American astronomer Hubble measured the spectral lines of galaxies, he discovered the quantitative relationship between the redshift of the spectral lines and the distance of the galaxy, that is, the phenomenon of celestial redshift. It can be inferred from this that various celestial bodies are now moving away from each other, and the distance is getting bigger and bigger, which means that the universe is still expanding.

Up and down the four directions, through the ages. The idea of the universe first came from Taoism, and the question of mystery and greatness depends on what Taoism says. ......Some are born out of nothing, and nothing is born out of being.

The universe that exists is there, and eventually disappears. In myths and legends, Pangu opened up the universe in chaos, and chaos is nothing. ......Three beings and all things, the composition of objects is yin and yang, yin and yang are not drowned by each other, so there must be order, morality is order, galaxies are moving, plants and trees are growing, this is agility.

Yin and yang, order, agility. ...The changes of yin and yang, the order has always provided balance, and the prosperity is the maximum balance that the order can maintain. After that, the order cannot restrain the agility, and the yin and yang are pushed by the agility to produce mutual flooding, and the balance collapses, and everything eventually disappears.

The increase in entropy in thermodynamics explains this. ......The law of energy conservation and equilibrium, which can be understood as this kind of nothingness, everything is not there, but everything is still there, is called chaos. When yin and yang are submerged with each other, the space is naturally gone, and the energy released by yin and yang submerging each other collapses to a point with the space.

How to make the order and time in this energy work again is Pangu's business. The moment it works, it may be a big **, and the energy is instantly converted into yin and yang, and nothing begins to exist.

The universe was formed by a big ** that happened about 15 billion years ago.

The matter that existed in the universe before it happened.

and energy are gathered together, and condensed into a very small volume, the temperature is extremely high, the density is extremely high, and then the big ** happens.

All the galaxies, stars, planets and even life that appeared in the universe were gradually formed in this process of continuous expansion and cooling. However, the theory of the universe that came into being does not yet explain exactly what existed before "the matter and energy that existed at one point"?

I'm not a physicist and don't know.

Formed by a large fireball**.

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.

It wasn't until the 20th century that two "models of the universe" emerged that were more influential. One is the steady-state theory, and the other is the big ** theory. In the late 20s of the 20th century, Edwin Hubble discovered the phenomenon of redshift, indicating that the universe is expanding.

In the mid-60s of the 20th century, Arnault Penzias and Robert Wilson discovered "cosmic microwave background radiation". These two discoveries give strong support to the big ** theory.

One of the most influential theories in the modern cosmic system, 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, the whole process of the great universe is: in the early days of the universe, the temperature was extremely high, above 10 billion degrees.

The density of matter is also quite large, and the entire universe is in equilibrium.
