readx;?? I asked the sages, "How old is the earth?"

Scientists have determined that the Earth's rock layers existed billions of years ago, based on carbon-14 measurements from rock excavations. Pen ~ fun ~ pavilion www.biquge.info but there is no doubt about it.

Hundreds of years ago, scientists based on the average salinity of the oceans and other aspects came to the same conclusion: the age of the earth is about 100 million years.

A brief discussion of the theoretical relationship between ocean salinity and the age of the earth: at the beginning of the earth's birth, the ocean was supposed to be fresh water, and as the river continued to wash the continental minerals into the sea for hundreds of millions of years, the salinity of the ocean was slowly increased. The salinity of the world's oceans is roughly the same, and the rate of improvement can be roughly calculated. This provides theoretical support for the estimation of the formation years of ocean salinity.

Salt content is generally washed out from the continent by rivers to the ocean, resulting in the gradual flow of nutrients from the continent to the ocean, resulting in the gradual desertification of the interior.

Salt is extracted from the sea to replace the salt lost by the human body, and there is some kind of countercurrent of salt from the ocean to the inland. This may also have a subtle impact on the estimation of the age of the earth, but the history of human activities will not exceed 10 million years even from the mythological age~, so the influence is extremely limited.

There is a contradiction between these two academic theories: Why do the rock formations be billions of years old, while the salt content shows that they are only 100 million years old? Some scientists have used the analogy that people usually use stones to build houses, and the earth may be reincarnated for about 100 million years, constantly destroying and reborn, that is, exploding into nebulae and then reconverging into new earths, and this cycle has been dozens of times.

May I ask the sages, which statement should I believe?"

The sage replied, "What do you think of yourself?"

I thought about it carefully and replied: "If the earth is reincarnated according to a cycle of 100 million years, and there are repeated destruction and rebirth, then how can it be that with such drastic changes in heaven and earth, there will be no physical and chemical changes in stones, and even nuclear fusion reactions, so this is contrary to the results of people using carbon 14 to determine the age of the earth." So I think it's okay to abandon the idea of reincarnation. In this way, the history of the Earth's billions of years can be roughly confirmed. What do you think of me?"

The sage nodded: "Yes." ”

Having solved the question of the age of the earth, the next question is the origin of the universe. Because if history is traced infinitely, this ultimate question must be involved.

The Bible says: God said that there should be light, and so the world began to be born; traditional Chinese culture says that there is an ancient god named Pangu in Chaos, who holds a Pangu axe to split chaos and open the heavens and the earth. In fact, there are similar creation legends in the history of various peoples.

In modern times, with the publication of Albert Einstein's "General Theory of Relativity", modern science believes that the world began with the Big Bang.

I asked the sages, "Which statement is true, should I believe in science or should I believe in theology?"

Prophet: "Don't simply dismiss science and theology. All exact knowledge belongs to science. All dogmas that involve more than exact knowledge belong to theology. Between theology and science, there is also a no-man's land that is attacked by both sides. There are always aspects of science that cannot be answered, and this is due to insufficient knowledge. Therefore, in the absence of definite knowledge, there is no possibility to be denied. ”

"That means I can choose to believe in either aspect, yes?" I asked slyly.

The sage did not answer, and seemed to acquiesce.

"Then I choose to believe in the Big Bang theory of the birth of the universe. If you follow the Big Bang, there was a super-black hole at the center of the universe before the Big Bang. The gravitational force outside the black hole is infinite, and the pressure inside the black hole is infinite.

All matter in the universe before the Big Bang was attracted to the black hole, and when all matter was infinitely compressed in the black hole, until it was converted from matter to energy, forming a state with no matter and volume, only energy. Sages, if you follow this statement, there is a question, when was the destruction of the universe before the Big Bang?"

"If you extrapolate this time in the time of the earth, it is probably an infinite number of years. It can also be a moment."

"How so?"

"Since all matter before the Big Bang has been destroyed and turned into energy, the new matter created after the Big Bang has no causal relationship with the matter before it. Therefore, the history that can be described by mankind can only be told from the Big Bang. Any attempt to explain the state of the pre-universe is ineffective, and the pre-universe and the present universe are two parallel trains in time, never intersecting. We can say what the age of the universe is, but it does not mean that this time plus how many years will be added to the pre-universe era. This will never be possible. ””

I asked, "How did the Big Bang happen?"

Sage: "Matter is attracted into a black hole to form a state where there is no matter, only energy. This energy-only state continues to collapse, and the pressure and energy become more and more concentrated, making the state unstable, causing the energy escape of the super black hole, known as the Big Bang. ”

I asked, "How did the universe come into being after the Big Bang?"

"In the process of the explosion, the energy radiates out. In the process of radiation, the pressure decreases rapidly, the temperature begins to decrease, and when a critical temperature is reached, the energy begins to be converted into elementary particles. These elementary particles exploded and diverged around, expanding into the current universe, and the universe is still expanding in some way. ”

"How do stars and planets form?"

"Elementary particles are not completely balanced in the process of divergence, and some parts are more concentrated.

The interrelationship of all matter can be expressed by the gravitational force between matter, and the only way to break through gravity is by a certain velocity. If you can't break through this speed, you can only move around the substance and can't leave.

Particles attract each other and capture each other, forming larger and larger protons, neutrons, and electrons, and as these three particles interact, atoms are formed.

The most light substances such as hydrogen and helium are produced at the beginning. These atoms in turn form more complex substances such as molecules.

With the gradual increase of these molecules and other substances, nebulae began to be produced. The nebula gathers locally and begins to accretion and compression, and when the mass of the gathered nebula material reaches a critical mass, it ignites the nuclear fusion reaction of hydrogen atoms at the center and emits light. And absorb the surrounding matter so that it grows larger and larger, and eventually forms stars. Nebulae that are not strong enough for nuclear fusion to form gaseous planets (containing only gaseous elements such as hydrogen, helium, etc.).

Under the influence of gravity, all the planets and stars form a gravitational circle connected to each other. ”

"Does the universe have boundaries?"

"With all gravitational interactions, the entire universe is destined to be finite and unbounded, that is, finite in volume, expanding but unable to break through. This property is very similar to the imagination of man (God), the human mind is limited, but the imagination of man is infinite, so the limits of science have something in common with theology. ”

"I still don't understand, is there a boundary in the universe?"

"When the universe was born, it was just a point of light created out of nothingness. From there, it radiates matter and energy to the surrounding area, so that the universe is bounded all the time, but it is constantly expanding. ”

"Then the outside of the universe should be empty, right? Is there any other matter or even the universe?"

"Whether it is or not, it doesn't make sense to humans in this universe. However, according to the speculation of scientists, there should be. Every universe may be a bubble, and bubbles come and go. ”

"And how did the sun form?"
