Is there any hope that human beings can observe the boundary of the universe in the future? After listening to the explanation of the scientists, I understand

In ancient times, people often looked up at the sky and wanted to know what the sun, moon and stars were? What is the name of the place where they are? For the ancients, the world we live in is an infinite space without boundary. However, with the rapid development of human civilization, it finally entered the era of science and technology hundreds of years ago.

The power of science and technology is powerful. With the help of science and technology, mankind has finally realized the dream of flying to the sky and walked out of the earth. When human beings walk out of the earth, we will know how much we have known in the past. The vastness of the universe is far beyond our imagination. At the same time, we also understand that the earth is not an infinite space, it also has a specific diameter and volume.

When human beings walked out of the earth, a new problem appeared, that is, does the universe have a specific size? Does the universe have boundaries? If so, how far is it from us? As for the mystery of the universe, there are three things that human beings want to know most. One is whether there is an alien civilization in the universe, the other is the origin of the universe, and the third is whether there is a boundary in the universe?

Today we will discuss the boundary of the universe. Does the universe have a boundary? On this issue, the scientific community also has great differences. Different scientists have different views. Some people think that the universe is infinite space and there is no boundary. However, some people think that there can be no infinite things in the world, and so can the universe. It may also have a specific diameter and volume like a star.

So, which of these answers put forward by scientists is likely to be correct? In fact, as early as last century, Einstein, a great scientist, gave his own conjecture about the boundary of the universe. Einstein thought that the universe may be a closed space similar to a fruit shell, which is infinite but bounded. Maybe many people don’t understand Einstein’s answer. What is infinite but bounded?

We can think of the universe as a sphere. Can you find its start and end on a sphere? Of course, it is impossible. A sphere itself has no so-called starting point and ending point, just like our earth has no so-called starting point and ending point.

But the sphere has a boundary, which I believe we all know. Einstein’s view on the boundary of the universe is like this. He thinks that the universe itself has no starting point and ending point. It is an infinite existence, but the universe is bounded. Later, by observing the universe, scientists found that distant galaxies are far away from each other, so they came to a conclusion: the universe is accelerating expansion.

In fact, to understand Einstein’s view that the universe is infinite and bounded, we can explain it with an example in our daily life. I believe that friends have blown balloons. When we blow air into the balloon, the balloon will continue to expand and become larger. And the points on the surface of the balloon are moving away from each other. Now I ask my friends, does the inflated balloon have a specific size? Does the balloon have a boundary?

I believe many friends know the answer, that is, the inflated balloon has no fixed size, because with the expansion of the balloon, its volume is also growing. But the balloon is bounded. This boundary appears when the balloon begins to expand. And the universe is similar to an expanding balloon. Under the action of a mysterious force, the huge sphere of the universe is also expanding rapidly step by step, and its expansion speed exceeds the speed of light.

Because the universe has been in rapid expansion, so it has no specific size, that is, its volume is infinite. However, the space of the universe has a boundary since its birth, and this boundary expands outward with the expansion of the universe. This is Einstein’s understanding of the boundary of the universe. He thinks that there is a boundary in the universe.

If there is a boundary in the universe, how can we observe it? In fact, to achieve this goal, it is very difficult to rely on aircraft detection. To know that the space of the universe is vast, no one knows how big it is now. Even with the range of the universe now observed, it is impossible for human aircraft to reach the boundary.

Einstein’s theory of relativity tells us that the speed of a body with a still mass can only be infinitely close to that of light, but cannot reach it. Under the existing physical system, the speed limit of an object is the speed of light, and the expansion speed of the universe exceeds the speed of light, so even if you take a light speed spaceship, you can never reach the boundary of the universe.

If we want to explore the boundary of the universe in the future, we can only rely on powerful observation equipment, such as astronomical telescopes. Its observation ability is very powerful, it can see tens of thousands of light-years, millions of light-years or even hundreds of millions of light-years beyond the star background. Only telescopes can hope to see more distant stars and the boundaries of the universe.

Some scientists have observed that a beam of light has been reflected back in the universe. The reflection is about 13.9 billion light-years away. So it is wrong to think that the boundary of the universe may be 13.9 billion light years away. In fact, this kind of cognition is incorrect. We should know that there are numerous celestial bodies in the vast universe, and it is not possible for light to go smoothly all the way. It is also normal for light to be reflected back when it encounters obstacles.

If one day in the future, human beings can observe the boundary of the universe through astronomical telescopes, what will it be like? In fact, all our knowledge of the boundary of the universe is a conjecture. The real boundary of the universe may be far more complex and mysterious than we think. It may still be there. Scientists have two tasks to explore the boundary of the universe.

One is to find out the origin of the universe from there, the other is to see if there is more space beyond the universe. If the universe is a sphere space with boundary, then the probability of other space outside the universe will be greatly increased. At the same time, it can also prove the pluralism of the universe. If so, the significance for human beings will be epoch-making.

We should know that there is space outside the universe, which means that other universes will also have the birth of civilization. Different universes will be born at different times, and the strength of civilization will vary greatly. If it is a very old universe, the civilization in it may have been so powerful that we can’t imagine.

Of course, if you want to observe the boundary of the universe, you can’t do it with the current optical telescopes. The reason is very simple. The expansion speed of the universe exceeds the speed of light. The light at the boundary of the universe can never come to the earth, so it won’t be observed by us.

If we want to observe the boundary of the universe, we need to develop more advanced observation models, such as gravitational waves, dark matter or dark energy. Only with the realization of space warping observation technology, may it be possible to surpass the expansion speed of the universe and go ahead to see what the real universe is? We are looking forward to that day.
