Is there a margin to the universe? Why? Is there a margin to the universe?

It seems that you are an astronomy enthusiast, and so am I, adding you in a moment.

Albert Einstein once said, "The universe is a finitely closed continuum in terms of spatial dimensions" establishing an unbounded and finite, finite and closed four-dimensional continuum.

This means that the universe has no boundaries (because it's always expanding), but it does have a size (which I really can't figure out).

We are a creature in the universe, either one or one.

I don't want to talk about the birth of the universe, in the space of the universe, according to the theory of relativity, it is very likely that it is a ring, through which time passes, and there may be another space, which is installed on the other side of the ring in the form of parallel lines, so we cannot meet it, but Einstein proposed that if this ring is extremely curved, it is possible to make it no longer parallel, and time will no longer be lost equally.

Everything in our world is separated by some mysterious force, and that's why we have everything that we can experience. It's impossible for you to know the answer to the question. With the finite life of human beings, it is impossible to comprehend the infinite universe. Unless you're dead.

There is a margin, how can it be conserved without an upper limit? You are a human being. Because of us, there is the universe. Humans are the same as animals, civilization is only a cover for crimes, language is the communication of conspiracy, and you are more boring than me.

According to Hawking's theory, the universe is finite and boundless. It's like you walk on the earth and there will never be a boundary. Because space can be bent. When you've been gone for a certain amount of time, you'll find yourself back in place.

There are six universes in total, each of which can travel through each other through something like a wormhole.

Can anyone understand you?

Hehe. Do you think you're researching something very profound?

This is already called "basic" in modern physics.

Do you know what the foundation means?

Personally, I agree with Hawking's theory, the universe is finite and unbounded, just like the earth, but it is not the same as the earth, it may be 4 or 5 dimensions or something, as we live in a 3-dimensional space, we can't understand this concept.

I can't answer the rest of the questions, I've been thinking about them before, but I can't get answers to them at the moment, and the world is wonderful because of these mysteries

The universe should theoretically be marginal. It's just that we humans haven't found it yet. And the universe is expanding at the speed of light. Therefore, with our current level of science, it is impossible to find the edge of the universe.

There are many theories as to why there is a universe. The most famous is the "Theory of the Universe".It is said that the universe is a space that emerges from the continuous expansion of a supernova**.

As for human beings, they evolved from nature. With the continuous evolution of human beings. Civilization and language emerged. I don't understand the rest. All are miracles created by nature!

At present, human understanding of the universe is not yet certain.

The universe should have a boundary like a balloon, are we human? Don't you belong to us. Language is the result of biological evolution, where did human beings come to ask Uncle Da to go to the Fifth Brain Disabled Hospital, welcome to you.

Is there a margin to the universe? Why?

A: Probably not, because the universe is expanding endlessly.

What are we?

Answer: The small point of this question should be composed of protons!

Why is there such a space as the universe?

A: Shortly after the results of the Proton Collider experiments came out, the scientist Uncle told you about Human? Language? Civilization? Why?

A: What do you mean?

Turn right when you go out of the psychiatric department.

Yes, because it is **, the edge is constantly expanding, because the cosmic background radiation is decreasing year by year.

Matter is a philosophical thing.

No... For the universe is still growing ...

In three-dimensional space, the universe has no boundaries.

The famous astrophysicist Stephen Hawking once said that the universe is finite but boundless, just like our earth, we all know that the earth is finite, but we can never find its boundaries, at least from the perspective of three-dimensional space.

And if we can find a way to enter the four-dimensional space-time, we may be able to break through the universe and reach the world outside the universe. Some people now think that the outside of the universe is actually a multidimensional space, but it is difficult for us to enter it. Just as a flat-slipped person who exists in a two-dimensional world cannot travel to our three-dimensional space under normal circumstances, it is difficult for us in three-dimensional space to travel to a four-dimensional or more space, unless the universe provides us with convenience and opens the door of time and space.

I guess the world outside our universe is like a world outside of a balloon. We are now comfortable inside the balloon, and as long as we can find a way to break through the balloon skin, then we will be able to travel freely between the universe and the world outside the universe. And I think that method should be able to allow us to travel between different dimensional spaces.
