What exactly is beyond the observable universe, and what does a truly complete universe look like?

Humans have been exploring what the universe really looks like. Is it pitch black beyond the observable universe, or is there some other unknown matter? There is still no accurate answer to these questions.

But it is precisely because of the existence of these curiosities that human beings have been exploring the universe. Just like when the most primitive human beings first appeared on the continent, they may not be able to understand what the earth under their feet is like, and only by constantly moving forward step by step can they gradually explore the true original appearance of the earth. For the universe, the author believes that the same is true, the truth may subvert cognition in the future, but there are still outstanding scientists willing to explore it.

What does the truly complete universe look like? This question seems to many netizens to think that the universe is also a circle, and it is like the earth is a huge star. However, scientists believe that there is a possibility of a circle, but it may also be a geometric shape.

If I had to describe it, it was like an inflated balloon that floated in space and grew bigger and bigger. <>

Because we really can't measure how big the universe is, whether it's a four-dimensional space or a five-dimensional space, so humans still can't observe the external shape of the earth. According to the current science and technology, human beings can observe the universe 90 billion light years away, but scientists believe that in addition to the observable range, in fact, there are many spaces in the universe that humans have not touched, which may be tens of thousands of times the earth. After all, if you compare the earth with the universe, it is likely to be like humans and the earth.

In addition, human beings have always wanted to go to other planets to explore whether there are planets like Earth in the universe, so that one day in the future, when the earth's resources are exhausted, human beings will have a second home to support the continuation of human civilization. Judging from the current pace of exploration, it is still a long way before the distant fireball can successfully land. From the perspective of the Milky Way, whether it is the Moon or Mars, they are just small spots of light visible to the naked eye.

You must know that the Milky Way is one of the smallest constituent galaxies in the universe, so the true size of the universe is far beyond human understanding. <>

To sum up, the author believes that the universe is like a complex spider web, with countless celestial bodies rotating naturally, and there are unexplored dark matter floating around it.

Outside the universe is a void, that is, the unknown, nothing exists in the void space, the universe in science is only what we can observe at present, everything within the scope of this space, this scientific basis is the hypothesis of the universe, because the universe was a void before the universe.

There are other universes outside the universe, many scientists believe that the universe has a clear boundary, but the universe we are currently in is too big, so it is difficult to observe, or it is possible to be in another dimension, about this, scientists have found a lot of evidence through cosmic microwave radiation, including even the friction traces of the universe being hit by another universe, coupled with the development of quantum mechanics, all make us more convinced of the other universe.

In the chapter "The Three-Body Problem", Beihai led the Natural Selection to escape, and the pursuit fleet later formed a starship Earth International with the Natural Selection after the Doomsday Battle of the Water Drop, and finally the Dark Battle occurred, and the one who survived was the Blue Space, and later, human beings sent the Gravitation to pursue the Blue Space in the Deterrence Era, and was accompanied by the Water Drops of the Three-Body Man, in that plot.

We often hear people say: "Seeing is believing, hearing is false", many people may think that this sentence is true, only what you see, is true, but tell us many examples, what you see is not necessarily true, eyes can deceive, to give a simple example, some magic, some casino poker, you stare at each other, what you see is true; But in fact, your eyes have been deceived, and the results are often fake.

<> this is a real-life example, and it would be more true if what was seen was not applied to space exploration, but to astronomy. Jillian Scade, a professor at the University of Sussex in the UK, explains that our perception of external objects is influenced by light and space.

Scientists say what we're seeing isn't real. The universe as we see it is only a thing of the past, although the speed of light is very fast, it also needs a medium and a certain amount of time to travel through the air. What we see in front of us is not its real-time state, but its past state.

At the same time, under the action of external forces, space will also be distorted to varying degrees, which makes it even more impossible for the form of the things we see to be its real form. Hundreds of years ago, with the continuous progress of human civilization, we embarked on a path of scientific development. Under the guidance of scientific knowledge, we have a new understanding of the world and have stepped out of the vast universe witnessed by the earth.

So, is the universe as we know it really the universe?

Perhaps many people think that seeing is believing, that everything we see is real, that everything in the world, everything in the universe, is real. However, with the rapid development of human science and technology, especially the continuous advancement of virtual reality technology, some scientists have doubts about the reality of the universe we live in, and some scientists speculate that our universe may not be real, but created by a virtual universe. When we perceive the world, we first send what we see through our eyes to the brain's visual system, which is then fed back to the brain through complex processing.

No; Because so far, human beings themselves have no way to go farther, which means that the current vision of the universe is not real, and what we see with the naked eye is only a very small part of the universe, the universe is boundless, and there is no way for human technology to overcome it at present.

is real; Although the sights we see are all scenes left behind by the past many years ago, he is also real, but he is very far away from us, and it takes time for him to pass on the scenes to us.

The observable universe includes celestial systems such as the solar system, the Milky Way, and extragalactic galaxies, as well as various celestial bodies such as planets and moons. After the universe is large**, some parts of the universe may be too far away from the earth, causing their rays to fail to reach the earth until now, so this part of the universe belongs to the observable universe. <

No one knows what is on the outside of the detectable universe, but it is estimated that it is still the same as inside. Because in recent years, with the rapid development of detection methods, the boundary of the detectable universe has expanded from 30 billion light-years to 90 billion light-years. It's still the same structure as the original detectable universe.
