What is the universe like, whether it is long round or flat, and is there an end?

The universe is boundless, and it is impossible to judge whether its shape is long, square, round, or flat.

The universe should be boundless, endless, beginningless, and infinitely large, so there is no such thing as a boundary problem. The universe already contains everything, and there is no question of internal or external, origin and extinction at all. The universe is infinite in space and has no beginning or end in time.

No matter which direction you go in, it should be endless and endless, and it cannot be blocked by anything, which is the infinite cosmic space.

The objects you see on the Internet are all colorful, textured, and very beautiful, but in fact they are pitch black, which is the image observed by the Hubble telescope. The celestial bodies seen on the Internet are all on the basic blurred black and white**, which are technically modified and sorted out by relevant personnel, and then released**. These are not what we directly appear to the naked eye, so don't be so naïve to think about how beautiful the celestial bodies of the universe are.

The universe is the unity of all time, space, and its contents

It contains all matter and energy such as planets, stars, galaxies, intergalactic space, and subatomic particles.

Some of the cosmic objects observed by humans are roughly composed of ordinary matter (the matter that makes up stars, planets, gases, and dust) or "baryons", dark matter, and dark energy. In the universe, the Earth is the only planet known to mankind that has life.

Yes, first of all, it's not because of rotation, because rotation only turns the star into a cylinder.

Stars originally evolved from relatively large blocks in nebulae. If you think about gravity, you can create a scenario in your brain, which is kind of like a snowball. If you have snowballed, it is not difficult to understand why the stars are round.

We all know that the reason why the planet is round is because the force of the gravitational field originates from the center of the star, pulling all the matter inward. The massive body of the planet, combined with the heat generated by the radioactive elements inside, behaves like a liquid, succumbing to the gravitational pull from the center of gravity for a long time, thus forming a circle. The only way to get all the matter as close to the planet's gravity center as possible is to form a sphere; This process is called isostatic adjustment.

But not all planets are round.

For smaller stars, such as asteroids, the gravitational force is too small to surpass the force of its own structure. As a result, these stars retain their irregular and incomplete shapes, rather than forming spherical shapes.

The theory of relativity attempts to solve this problem using the concept of spatial curvature.

Let the curvature of the space be g

1.Positive curvature space: 0 g go

Space expands and then contracts, spherical.

2.Negative curvature space: from g=0 to g=+, continuous expansion, no contraction, unlimited space.

Note: The negative curvature space contains an extreme case, which is the Euclidean space, but it has been shown that this does not exist.

So, the key question at the moment is to determine whether the universe has an expansion limit point, go, which requires complex measurements, and if it exists, it is spherical.

Is there an end to the universe? What's outside the end? Is there a beginning and an end?

Where do we come from? Why exist, why die? When did time start and when did it end?

Can the human brain understand itself??? Finding the answers to the above questions is what human beings have been pursuing and exploring! However, the current level of intelligence and knowledge of mankind is not enough to understand such a problem, let alone the entire universe!

This is beyond the limits of human imagination!

Therefore, even though we have carried out various explorations and researches and achieved certain gains, we are only in the stage of inference and imagination, and there are still many things in the universe that we cannot know! Unexplainable stuff!

Don't follow the crowd and don't take it too seriously, you will find that some of our conclusions are based on assumptions, and no one will give you the right answer at the moment, and you may never get the answer.

The universe gives birth to wisdom, can wisdom understand the universe?

Can a cat understand why the earth has four seasons? Of course not, but it's too easy for us! The cat's brain capacity is not enough!

In the same way, there are things that human beings cannot understand, and human intelligence is limited and not omnipotent! Our intellect wants to truly understand the universe! I'm afraid it will come when we evolve into or emerge into more intelligent life!

But it takes time, maybe 100,000 years!

Albert Einstein said: The most incomprehensible thing in the universe is that the universe is intelligible!

Is the universe round? I can't see it, I can't answer it, and scientists probably can't see it. But I guess it should be.

Huainanzi. This scripture says: "Carry the circle and walk the square".

It shows that in ancient times, some people believed that the sky was round. Let's not talk about the ancients! Let's just say that there are countless celestial bodies in the universe, which one is not round?

Farther away, the Milky Way, it's made up of countless nebulae and star clusters – nebulae and star clusters are all round, right? Circles are similar to circles. In the solar system, the moon circles around the earth, the earth takes the moon and circles around the sun, and the sun takes its family to go around a larger ......circle togetherTime, minutes, seconds, that is, playing in circles, I don't believe in looking at the clock or watch.

The shape of the universe cannot be described by a concrete object that we see, from the outside of the universe, it has no shape, it is just a point, that is, there is no concept of time and no concept of space. From the inside, it is having space and time. In a normal space, 1L of space can only hold 1L of water, but this is not necessarily the case in a distorted space.

Again: if the universe can be understood, it is an incomprehensible thing.

The universe is spherical, if according to the big ** theory.

No one in the world knows what the universe is shaped like because no one has ever seen it! What astronomers describe is to illustrate the shape of the universe by calculating or extrapolating or estimating the observed matter, but this is incomplete, because too much matter in the universe cannot be observed, and the motion does not follow the laws of general physics. No one can be 100% sure of the shape of the universe without truly observing the entire universe!

If the light of the universe is counted into space, then the universe is round.

Hehe, I never know that there is an exact conclusion about this, but I think the universe will not be round, there should be no shape, such as the Milky Way, can you say that it is round? Can you say it's square? No. The universe is even more so.

The universe is like a balloon, expanding rapidly after being big**, until it reaches an unknown size, and it is still expanding, because there is no time and space outside the universe, so the shape of the universe is a mystery!

It is indeed possible that the shape of the universe is a circle. However, there is no definitive answer to date. When it comes to the vast universe, for human beings, this is our home for survival, and it is also the "ultimate problem" that has plagued the history of human civilization for tens of thousands of years.

Where did the universe come from? How does the universe exist?

All these have constantly triggered our exploration and reverie about it. Once upon a time, human beings still felt that "the sky is round and the place is round", and all we can see is everything in the world; There are all kinds of immortals living in the universe, and there is heaven at the top; Now, of course, we don't think so.

Modern science has proved that the universe is a 13-billion-year-old universe, and the center is a "Schwarzschild singularity", which is not included in any physical laws. ** After this happens, three billion years will completely shape the state of existence of the universe; However, what exactly the shape of the universe is not yet known.

In the last century, the famous physicist Hubble calculated the diameter of the universe through a series of calculations: 93 billion light years. To this day, the universe is still expanding; Mr. Stephen Hawking believes that this "expansion" actually has a module.

The essence of the universe is a huge three-dimensional sphere, or "circle". It expands continuously, and when it reaches an upper limit, it begins to contract, shrinks to the extreme, and then continues to expand, and so on. This is the famous "** universe vision", and it does sound very imaginative;

However, there is a lack of empirical support for this. Although, it has many fans, some of whom are also bigwigs in the academic world; However, this is still just a hypothesis.

To put it bluntly, it's okay if you think the universe is square, after all, we haven't found a definite answer yet. However, with the continuous development of our technology, it is believed that the day when we will reveal the ultimate secret of the universe is not far off.

Human beings' ability to explore the universe is still very limited, and there is no way to reach the end of the universe, or rather, it is not yet certain whether the universe has an end. The universe does not have to be circular because the end of the universe has not yet been found.

It is impossible for us to know what shape the universe is, in philosophy it is something that contains everything, in the material sciences it is defined as the sum of time and space. According to modern cosmology, the universe is finite and boundless. What shape does something without boundaries have?

Modern astronomical theories approximate the universe as spherical, and it is believed that the universe originated from an unprecedented event. Since the dawn of the universe, it has been expanding in size, encompassing all the planets and matter.

The universe is unpredictable, it can change shape at any time, and the universe cannot be estimated by human beings, so we can only wait for the future to be discovered.

Regarding the birth of the universe, we all know that it originated from a singularity 13.7 billion years ago**, but scientists still do not have a clear explanation for where this singularity came from. So, what is the universe we live in today? According to the introduction of scientists, since its birth, the universe has always been in a stage of continuous growth and expansion, and now there are more types of celestial bodies in the universe than can be counted, so is the universe a circle in our subconscious, or other shapes that we can't think of?

Let's see what scientists are surmising!

Because planets such as the Earth are spherical, stars such as the Sun are spherical, and galaxies of all kinds are also flat disk structures, scientists speculate that the universe is also a flat disk structure such as galaxies, because only in this way can the various celestial bodies in the universe rotate around the same center under the action of gravity. Even some scientists, after computer modeling and simulation, believe that the universe is likely to be the shape of a car tire, but in the eyes of Einstein, the greatest scientist in human history, perhaps the universe we see is all an illusion.

Einstein believed that the current human understanding of the universe is wrong, and through the study of the theory of relativity, Einstein believed that the universe is also a kind of matter, as if it is a living thing, rather than a void scene that we see through astronomical telescopes. We all know that Albert Einstein once speculated that there are very likely that there are multiple universes, and that the universe that we humans exist in is only a small part of it, because in the Theory of Relativity, space and time can be distorted, and once distorted, countless spaces will be created.

Nowadays, some scientists have a new understanding of the shape of the universe on the basis of Einstein's "Theory of Relativity", and they believe that the universe is very likely to be a "potato" shape, and all of them are high and uplifted, although it can be regarded as a sphere, but it is indeed an irregular sphere like a "rugby ball". However, there are also some scientists who believe that the universe is a plane, just like the "plain" on our earth, we all know that the plain can be extended infinitely, if it is not blocked, then the universe may also have no boundaries and spread infinitely.

At present, many scientists have begun to tend to the idea that the universe is a "plain", because they have found that no matter from which angle the universe is explored, the "plain" theory can make sense, simply put, our universe is currently on a very perfect level, even if it is affected even the slightest, it will change and no longer be perfect. In addition, even the slightest distortion will form a new space, and our universe will be completely different.

Although we don't believe that the universe is the work of the "Creator", the universe is really amazing, and the more we study it, the more we will feel that the universe is really too perfect and amazing, and we human beings, as the only intelligent life in the universe currently known, are really so lucky! What shape do you think the universe is in?
