What is the universe, is there an edge, more detailed, different angles

The universe is a general term for the vast desert space and the various celestial bodies and diffuse matter that exist in it.

The universe is the material world, which is in constant motion and development.

Huainanzi Yuan Dao Xun".

Note: "The four directions are said to be the universe, and the universe is said to be the universe throughout the ages, in order to metaphorize the heaven and the earth." That is, the universe is the general term for all things in heaven and earth.

For thousands of years, scientists have been searching for when and how the universe came to be. It is only today that scientists are convinced that the universe was formed by a large ** that occurred about 15 billion years ago.

Before the ** happens, the matter and energy in the universe are gathered together and condensed into a very small volume, the temperature is extremely high, and the density is extremely high, and then the big ** happens.

All the galaxies, stars, planets and even life that appeared in the universe were gradually formed in this process of continuous expansion and cooling. However, the theory of the universe that came into being does not yet explain exactly what existed before "the matter and energy that existed at one point"? The "Big ** Theory" was created by Gamow in 1946.

Suggestion**. It's good, check it out!

Wait a little longer when you open it!

The four directions are said to be the universe, and the universe is said to be the sky throughout the ages.

There should be boundaries in the universe.

We can think about it when the universe was still a cosmic egg. That must be finite, so even if the force is infinite when the big ** is large, it is impossible to make the limited space explode an infinite space.

And the concept of finite and boundless is that the universe has a boundary, that is, you can never reach the boundary. It is likely that the edge of the universe is a force strong enough that any matter that comes close to it will experience a repulsive force that causes the object to make a sound in the direction of 'absolute' motion, but in fact its relative direction of motion does not change, because this repulsive force affects the entire universe. We can understand that a person who has a very powerful telescope on the earth looks in a certain direction, and it is very likely that he will see the earth and even himself in the mirror after a certain year, and the reason is that when the light moves forward in a straight direction (regardless of other forces), it will continue to receive a repulsive force when it is constantly approaching this 'wall', and gradually, this repulsion force will become greater and larger, so that the light will continue to run at a certain curvature.

Eventually, back to square one. (I don't know if it's spherical or not, but since the sphere is a perfect shape or state, I think the universe will 'consider'.)

To put it simply, if we are on a two-dimensional basis, as long as the speed of human beings does not exceed every second, we will never go out of the earth. At this point, in a way, we think that the earth is infinite.

Of course, the universe is still expanding, that's for sure.

Perhaps, the universe is so big, and the whole world (all the material world) is also that big. The outer part of the universe is 'nothing'. However, this is unacceptable to many people, after all, there has not yet been a situation in our world where there is a finite thing that is 'nothing' on the outside.

Otherwise, as long as it is in a limited space, there must be a space outside, which always feels too far-fetched. Scientists, then, don't have to argue about what is finite or infinite. Because, there must be room outside of a limited space, so everyone is still arguing about something.

The universe is the sum of time and space.

There are no edges, but they are limited.

The universe is similar to a ball, you walk on the ball, there is never an edge, but the ball has a size.

I suggest you take a look at books on the universe, such as Cosmic Secrets

There's a side, but it's not three-dimensional, and even if you get to the edge of the universe, you can't stretch out your hand. Of course, you'll never get there. A Brief History of Everything says that our universe originated 1.37 million years ago.

The original meaning of the word universe is infinite, and the universe is still the universe!

The universe is my home.

Family planning depends on everyone!

1. There are many shops on this side of the universe. Isn't there a store on the other side of the universe?

2. On this side of the universe, the words are the current words, if on the other side of the universe, are the words they wrote ancient?

3. The house on this side of the universe will not move. On the other side of the universe, will the house walk like a human?

4. And on this side of the universe, we sit on a chair to attend class, but on the other side of the universe, do they sit on the ground to attend class?

5. On this side of the universe, the moon is from lack to round to short. On the other side of the universe, is the moon round and waning and then missing?

6. Can a person sit on the head of the house? On this side of the universe there is day and night. Is there only day or night on the other side of the universe?

In my mind, the universe should be boundless, 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. I think it's absurd to think that the universe is boundary, and if the universe is boundary, what is that margin? Is there no beyond the margins?

And since there are edges means that there will be edges, this question is actually difficult to justify, how can people who say that the universe has an end explain it? The only thing that makes sense is that the universe is infinite and infinite! The universe is mainly composed of infinite space, and the infinite space exists there for eternity, how can there be a question of formation and disappearance?

Matter in the universe can only be in an infinite cycle, endless and endless. It can be said that the infinite universe is indeed unimaginable to us, and it has long been beyond the scope of human cognition! But this is the universe, a mystery that humanity will never be able to solve!

Strictly speaking, the theory of the universe itself is an unproven hypothesis, and there are still many doubts that are difficult to justify. Therefore, it is difficult to say whether the universe has really happened, for example, the so-called singularity is a very absurd singularity, how big is this singularity? How long has it been around?

Why all of a sudden? I'm afraid no one can say, including the author of the theory. In short, since the universe is a hypothesis, why take it too seriously!

The universe is finite in space, but it has no edges.

I don't think anyone can give you an exact answer to this question.
