Ask for good knowledge: What is the universe? What is the universe? How did the term come from?

The ancients said that throughout the ages, it was called "Yu", and the Quartet was called "Zhou". is what my friend said earlier, Yu is time; The universe is space.

Therefore, the universe is a coordinate system of time and space.

All space within the coordinate system is the universe.

The universe is only a description of the coordinates of space and time, which neither reflects life nor death, but only expresses a kind of "existence".

Yu: Time, Space, combined to interpret is a diary that records events in any corner of this world, everything exists in the universe, leading to an infinite future, everything is not in the universe, recounting the distant primeval times, everything has and everything is nothing.

lz, this question is not clear. Is it the universe in the scientific sense or the universe in the philosophical sense?

Don't go for the essence. There is no essence, only appearance. When you get rid of the appearance, you will find that there is nothing behind it.

If you want to be philosophical, you still want to be smaller. After all, human thinking is limited. No matter how big or small, no matter how long or short, no matter how beautiful and ugly, no matter how gentle and cruel, the universe is still a universe.

I am still who I am ...

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

Universe Summary] The universe is the general term for all things in heaven and earth. The universe is a material world, which exists objectively and does not depend on the meaning of human beings, and is in constant motion and development, with no opening in time and no end in space. The universe is diverse and unified; diversity in the diversity of material expressions; Unity lies in its materiality.

宇 (yǔ), universe (zhòu), the four directions up and down said yu, throughout the ages and the present. Xinhua Dictionary In the pluralistic Chinese language, "Yu" represents the upper and lower four directions, that is, all space, and "Zhou" represents the past and present, that is, all time, Yu: infinite space, Zhou:

Unlimited time. So the word "universe" has the meaning of "all time and space". Linking the concept of "universe" with time and space embodies the wisdom of the ancient people of our country.

The word "universe" first came from the book "Zhuangzi", "universe" refers to all space, including east, south, west, north and other places, which is boundless; "Zeus" refers to all time, including past, present, day, night, etc., which has no beginning and no end.

In short, the shape of the universe is an unsolved lock in the heart of human beings.

Scientists estimate that the diameter of the universe is about 30 billion light-years. (1 light year = 9454254955488 km).

宇 宙 (yǔ zhòu), "the four directions up and down the universe, the ancient and modern times." —Xinhua Dictionary

It is generally believed that the universe is all the objective matter of the world in which we live, including time and space, and everything that is discovered or hidden.

Specifically, you can look at the information on the "universe" in the encyclopedia, and you can also read books about the universe.

I think you mean more than that, but the doubts about the universe have not been completely solved since ancient times, and I can't give you a sure answer to this question now. Although various religions claim to know the truth of the universe, these "truths" themselves are in conflict with each other, so how can they distinguish between the true and the false? Everything needs to be further studied, and everyone has the right to think and deduce on this question, and maybe the right answer is born in you.

However, all of this requires solid evidence, and so far, there is no tangible evidence to prove how the universe was born and developed, and naturally it is impossible to explain what the real universe is.

It would be nice if the cosmology was solved, we live in the Milky Way, and of course there are extragalactic galaxies.

Four-dimensional refers to three-dimensional + time dimension, four-dimensional is to establish a time or add an extra space between objects, in physics and mathematics, a sequence of n (n can be non-integer) numbers can be understood as a position in an n-dimensional space. Such a concept; The earth is an example, who first put forward it is better to say who understands it first, Einstein has clearly explained to us in the "Theory of Relativity", in fact, the universe is five dimensions, and the earth is four dimensions, but now science is highly developed, compared to the past only theory as the basis, so Einstein's explanation is actually wrong, the universe actually has n dimensions, there are 7 dimensions in our galaxy, and there are the remaining 4 dimensions in the universe that we can observe, So now we're only finding 11 dimensions.

Cosmic dark matter is actually a special substance that we can't see but can affect the total mass of the universe, and it can be a potential thing in any corner of the universe and on the earth, and it is mentioned in the "Theory of Inflationary Universe" that a substance that can imperceptibly affect us refers to dark matter, and dark matter accounts for 90% of the total mass of the universe, which provides a strong evidence for the universe to be large; Of course, there are special instruments that only measure the dark matter of the universe in modern times.

And the four-dimensional creatures proposed by the landlord are actually many, many; But if you add one dimension to the fourth dimension, that is, the fifth dimension, is there a creature that belongs to the fifth dimension?
