Why is it said that the universe is eternal but it is not?

Hello. That's because of the two most popular cosmological theories, the "Eternal Theory" and the "Great ** Theory".

Eternity Theory holds that the universe has existed for an infinite amount of time and will continue forever.

At that time, this theory could not explain why the universe had not yet reached a state of heat death, that is, the heat at any point in the universe was equal. Everyone until the heat will spontaneously transfer from hot objects to cold objects, so an infinite amount of time will definitely cause the universe to reach a heat death.

But the Big Theory can explain the problem, but it can't point out what the end of the universe is.

Since the universe is a combination of time and space, and space is three-dimensional, then three-dimensional space plus time constitutes a four-dimensional cosmic space-time.

You can think of it this way: space runs in the orbit of time, and this is the universe.

Eternity is eternal constancy, that is, it does not change in the dimension of time.

To put it simply, time is one-dimensional, space is three-dimensional, and there are four dimensions in total.

The so-called universe refers to the place where matter exists. Eternity can be understood as the infinite extension of time.

Eternity refers to time, and impermanence refers to matter.

What is multi-dimensional is seen by people, and it is different from different angles, you can understand it as three-dimensional or four-dimensional.

The universe is not infinite, it is only because it is expanding all the time that others think that it is infinite.

The eternity of the universe refers to the fact that there is no beginning or end time in the universe itself, that is, there is no limit to the existence of the universe.

According to the current scientific theory, the universe was born about 100 million years ago, and at that time, the "big **" occurred, and the universe began to expand from an extremely compact state. Although the universe has existed for a certain amount of time, it has no beginning or end, and no boundary. Current scientific observations suggest that the universe is expanding, and there is no indication that it will stop expanding or contracting.

Therefore, the universe may be eternal.

However, the eternity of the universe is not absolute, nor is it completely certain. Due to the limited understanding of the universe by human beings, it is not yet completely certain that the future development trend of the universe will develop. Some scientists believe that the universe may end at some point in the future, and other changes may occur.

For example, some scientists believe that if there are enough black holes in the universe, they could swallow up the entire universe, leading to the end of the universe. There are also scientists who believe that the universe may have a "big collision" at some point in the future, causing the universe to contract or terminate. However, these assumptions have not been fully proven and remain a controversial issue.

In addition, the eternity of the universe is also affected by the fundamental nature of the universe. According to current scientific theories, the basic properties of the universe include the density, velocity, and direction of the universe. If the density of the universe is lower, it may be eternal.

If the density of the universe is higher, it may contract or terminate at some point in the future.

The direction of the universe may also have an impact on the eternity of the universe. If the direction of the universe is "open", it may be eternal. If the direction of the universe is "closed", it may contract or terminate at some point in the future.

In general, the eternity of the universe is a complex issue that has not yet been fully resolved. Some scientists believe that the universe is eternal, while others believe that the universe is finite. Therefore, this issue remains a subject worthy of in-depth study.

1. Time exists and changes with the movement of matter. There is no time to leave matter, and there is no matter to leave time. Then the movement is inevitable and eternal.

Even the singularity that Hawking said. It must also be uncalm and athletic inside. Then time will not stop burning!

2. The law of conservation of energy. Energy neither arises nor disappears out of thin air, it simply transfers from one object to another or from one form to another, and in the process of transformation or transfer, the total amount of energy remains the same. Energy is eternally existent, and as a measure of the continuity of the system, time itself will also exist eternal.

3. Absolute zero cannot be reached or any object has radiation! All of them support the infinity of time.

In the short life of a person, the earth is eternal, in the long years the earth is changing, the innate gossip period is 8 festivals 360 days, the development to the current 365 days is strange. In the distance, the climate also changes, even if the myth says that during the Great Flood, it must have been formed by the high temperature, the ice and snow melted, and the water level rose. And the ice age, it's all a change.

The big cycle, the small cycle is rough and unchanged, and it should be ever-changing. Change is the unchanging truth. It seems contradictory, and people live between contradictions.

As for the destruction of the earth? Humans can't see it. It must have been impossible to survive long before it was destroyed.

I think there will never be eternal matter and celestial bodies in this vast universe. Because, no matter what there is, there is a time when it is exhausted, that is, if it is nothing, it is finally destroyed! Jian Jianlet single than imitation, no matter whether the machine is made of the best quality Jisen steel, it will eventually be scrapped into scrap iron.

Then, it comes out of nothing.

Therefore, it is said that there is nothing in the lead bureau, and there is nothing out of nothing, which is the law of the heavenly body!

The universe is finite and infinite, and the two contradict each other. If it is limited, some people will ask: what is behind this finiteness? The questions continue to be asked, endlessly. Is the universe infinite and beginningless?

Today's scientists believe that the universe was formed 13 billion years ago from an infinite density of "singularity"**, before which there was no universe, no concept of space and time. However, behind this argument lies a serious question: what state was the singularity in before the final explosion?

Is there the wisdom and power of the gods to push it? If space, time, and matter are all ready to develop in the belly of the "singularity", this is also called it, and research believes that the universe is still expanding, and when it expands to a certain extent, it will shrink to a singularity, then this.

Is the singularity on a different starting line? Is the universe pluralistic? The speed of light is the fastest, and it is possible to have anti-matter in the case of super-light speed, without antimatter, can the universe expand and exceed the speed of light? Is there time and space in those areas that the expansion has not reached?

The scientist Immanuel Kant's "Three Laws of Contradiction" outlines the finite and infinite universe, and one of the two must be taken, Kant believes that the universe has no beginning and no end in time, no edge in space, and the universe is infinite.

If the universe is infinite, outside the universe, the multiverse, multi-dimensional space, etc., these do not exist, and the big ** does not exist, and if it exists, it is only the interior of the universe**.

The infinite universe, with no center, no direction, and very difficult edges, makes it possible to maintain the conservation of gravitational force, so that the interstellar space can run and drift regularly. Otherwise, the so-called sinister inadmissibility of the edge of the universe will make the universe come to naught.

What is the meaning of knowing the infinite universe? The infinite and finite universes give people a sense of vastness and depth, and the infinite universe is more vast and breathtaking than the finite! Whenever I think of it, it inspires us to have confidence and courage in life and governance, to serve the society, and to promote social peace and prosperity.
