What is the universe really like? Maybe everyone has a different opinion, can you tell us what you t

The universe is created by motion.

Originally, the universe was in a "zero-sum" state with no space and no matter, that is, "nothing". When motion takes place, the universe gives rise to space and matter. The movement of matter in space gives rise to the physical properties of matter. The universe has the following characteristics:

1: Movement produces everything. In other words, everything is produced by motion, and the study of physics cannot succeed without giving up motion.

2: In a closed system, nothing can arise or disappear alone, and when a thing in one arises or disappears, it must simultaneously produce or disappear a thing in the opposite state of the same quantity.

3: The universe arises from "nothing", which guarantees the state of "nothing", that is, the total state of the universe is a "zero-sum" state. That is to say, in the universe everything can find the opposite state of "her".

4: Space (length s) and matter (mass m) are in opposite states to each other. Space and matter are a pair of opposite states of the highest order in the universe.

Matter can be understood as with""Positive" energy in negative space. And there is m+rs=0, r is a constant. r=cc/g。

It can be seen that there is a relationship between the matter in the universe and the size of our universe. When space is zero, matter is also zero, which means that there is no "singularity" in the universe. Space expands, and matter increases.

As long as I measure the size of space, I can know how much matter is in the universe.

5: Any point in the universe is the central point of the universe. In other words, the length of the universe is the same at any point in the universe.

6: The characteristics of the universe are closely related to the material properties of the universe.

The above is my personal view of the universe.

What is the universe like? I'm afraid no one can say clearly, and no one will ever be able to say clearly!

But you can say whatever you want, and no one has confirmed that what you said is wrong!

One of the most influential theories in the modern cosmology, also known as the Great ** Cosmology. It illustrates more observational facts than other models of the universe. Its main point is that our universe has a history of evolution 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 of the big **, the whole process of the big ** is:

In the early days of the universe, temperatures were extremely high, above 10 billion degrees. The density of matter is also quite large, and the entire universe is in equilibrium. There are only some elementary particles in the universe, such as neutrons, protons, electrons, photons, and neutrinos.

But because the whole system is expanding, the temperature drops very quickly. When the temperature drops to about 1 billion degrees, the neutron begins to lose the conditions for its free existence, and it either decays or combines with protons to form elements such as heavy hydrogen and helium; It is from this period that chemical elements begin to form. After the temperature drops further to 1 million degrees, the early process of forming chemical elements ends (see Theory of Element Synthesis).

The matter in the universe is mainly protons, electrons, photons, and some relatively light nuclei. When the temperature drops to a few thousand degrees, the radiation decreases, and the universe is mainly gaseous matter, and the gas gradually condenses into gas clouds, and then further forms a variety of star systems, which become the universe we see today. The large ** model can uniformly illustrate the following observational facts:

1) The big ** theory asserts that all stars are created after the temperature drops, so the age of any celestial body should be shorter than the period from the temperature drop to today, that is, it should be less than 20 billion years. This is evidenced by the measurements of the ages of various celestial bodies. (2) Systematic spectral redshifts are observed in extragalactic objects, and the redshifts are roughly proportional to the distance.

If explained by the Doppler effect, then the redshift is a reflection of the expansion of the universe. (3) The abundance of helium is quite large in various celestial bodies, and most of them are 30%. Using the stellar nuclear reaction mechanism is not enough to explain why there is so much helium.

And according to the big ** theory, the early temperature was very high and the efficiency of helium production was also very high, which can explain this fact. (4) According to the expansion rate of the universe and the abundance of helium, the temperature of each historical period of the universe can be calculated. Gamow, one of the founders of the Great ** Theory, once predicted that the universe today is already very cold, with only an absolute temperature of a few degrees.

In 1965, a microwave background radiation with a thermal radiation spectrum was detected in the microwave band, and the temperature was about 3 K.

abcdefghsr Your statement is basically the same as my idea, but it's not that no one will ever be able to say clearly, but in our generation, I'm afraid no one can say what the universe is like, and I agree with the rest, no matter who explains the universe, it's all a hypothesis, what is the most accurate answer? Only God knows. If you don't believe it, you wait, maybe the right answer today will be the wrong ...... tomorrowTired ......I can't tell ......

It's like the last part of Man in Black.

The universe is finite and boundless, it's as simple as that.

The universe is four-dimensional or higher, and people live in three-dimensional space, so it is difficult to imagine what the universe looks like.

I think it's like the title of Stephen Hawking's "The Universe in the Shell", the universe is just a very ordinary fruit shell, placed in a larger space, and there are many larger creatures than us in that big space, people are just in this small fruit shell, maybe one day they will crack this shell open, and the universe will become a different scene.

Hehe, it's just my imagination.

The universe is the intersection of time and space.

Just because it's like you said. If people go to observe this universe. Because we can't see the whole picture, it's hard to say what the real universe will look like.

Nowadays, scientists are still divided into two factions, one is said. The universe is boundary. The other school of thought said that the universe is boundless, and asked rhetorically:

If there is a margin in the universe, what is beyond that horizon?

Because the universe is endless, and every thing in the universe has its own characteristic attributes, human beings' ability to discover is limited, and what may be discovered in the process of infinite continuation is also incomplete, and it may only be the tip of the iceberg.

Because the perspective of human exploration of the world is limited, and it is impossible to truly understand the entire universe, and the current exploration is only to speculate on how the entire universe develops through a part of the planets, so it is impossible for human beings to know the whole universe forever.

The universe is vast and infinite, and people's exploration of the universe has never appeared, but at present, the field that human beings can explore is only a drop in the ocean.

Because the universe is very large, there are many mysteries in the universe that we cannot explore, at least not with current technology.

There is only a universe of large.

The mystery is endless. Why not?

I just didn't find it.

Are there really aliens? It's still a mystery! Although there is no definite evidence yet, I believe that there must be other life in the vast universe!

I'm not guessing! The universe is so big that there are no surprises! Although it takes a lot of conditions to give birth to life, it is not impossible, and the earth is an example. There are countless planets like the Earth in the universe, is it only the Earth that has life?

Even if all life needs water, there is more than one planet with water. At present, there are only no planets with liquid water in the solar system, and there are many galaxies the size of the Milky Way in the universe, and there are countless ones that look like the solar system! Are you afraid that you won't be able to find a second Earth?

Although we can't find aliens yet, won't aliens with more advanced technology than us look for us? So far, there have been many things that resemble extraterrestrial spacecraft, collectively known as UFOs, and although 99% of UFOs are masterpieces of nature, aren't there still unproven ones? Aren't they alien spaceships?

To sum up, extraterrestrial life is definitely there! It's just not discovered.

A few days ago, some scientists said that they had calculated that the planets and star systems in the Milky Way galaxy are similar to the Earth-Sun. According to research, there are about 1% of stars of the same type as the Sun in the Milky Way, and at least 10% of them have planets, that is, 100 million stars like the Sun have planets.

So the future will definitely be discovered.

Are there really aliens in the universe?

I think so. Because the universe is so big, and the universe is expanding faster than the speed of light, I also think that human beings will never be able to understand the universe in its entirety.

Under our current level of science and technology, it is impossible for human beings to see the whole of the universe, because the universe is still spreading, so the difficulty of seeing the whole universe is constantly increasing, so it is possible that human beings will never know the whole of the universe.

The universe is too big, human beings can no longer be small in the universe, and the universe is always expanding, and human beings will never be able to explore the whole picture of the universe.
