After human beings walked out of the earth, we finally learned that there is even more vast space outside the earth. The earth is not even a small dust in front of the universe.
After we knew the existence of the universe, mankind found a new goal, that is, the stars and the sea, becoming the overlord of the universe. Human beings were born on the earth millions of years ago, and after a long period of evolutionary development, they became the hegemon of the earth and stood at the top of the food chain.
When mankind became the overlord of the earth, we felt very proud. At the same time, many people did not know which direction mankind should work towards in the future. Until we stepped out of the earth and saw the vastness of the universe, we had a new goal.
Of course, to become the overlord of the universe and the most powerful super civilization in the universe is far more difficult than becoming the overlord of the earth. Compared with the universe, the earth is too small. To become the overlord of the universe, we must first have a sufficient understanding of the universe and solve all the mysteries of the universe, especially two important ultimate mysteries. One is the universe. The origin of, the other is outside the universe.
Regarding the origin of the universe, the current mainstream view is the Big Bang of the Singularity, which is a Big Bang that originated 13.8 billion years ago. After the birth of the universe, it has not stopped. It is still expanding outwards rapidly. It has expanded for 13.8 billion years so far, and the speed has exceeded the speed of light.
No one can say exactly how big the current universe is. With the current human technology, the universe we can observe is approximately 93 billion light-years. This range may be only the tip of the iceberg of the entire universe, and the continuous expansion of the universe indicates that there should be a vaster space outside the universe.
So what will the outside of the universe look like? For the situation outside the universe, we are currently unable to detect and understand, because we can not even observe the edge of the universe, let alone detect the situation outside the universe. Although we can’t detect the situation outside the universe, it does not hinder people from guessing about it. Scientists have also put forward three views on this, and the last one is even more frightening.
The first point of view: there are countless parallel universes outside the universe. I believe many friends of multiverse theory know that this is a conjecture of scientists about the universe, and this view is supported by more and more scientists.
Before human beings walked out of the earth, by looking up at the starry sky, we guessed that there should be a bigger world outside this world. When human beings walked out of the earth with the help of science and technology, we finally confirmed the guess of the ancients. There is indeed a vaster space outside the earth, and the earth is nothing but a dust in this universe.
When human beings just walked out of the earth, our observation range was very limited, basically limited to the solar system. With the continuous advancement of human science and technology, after we have more powerful telescopes, we can finally observe the starry sky outside the solar system. At this time, we know the existence of the Milky Way. And the solar system is just a dust in front of the Milky Way.
Later, we observed an even larger universe outside the Milky Way, until the observation range was expanded to 93 billion light-years. Through these, we understand the truth that there is a heaven outside the sky. Our observation technology is constantly improving, and the observation distance is also greatly increasing, but we can still see more distant space. It is not nothing, on the contrary, it is very exciting, with various galaxies everywhere.
If we look at the perspective of the universe and pass through the universe, will we also see a more vast and wonderful world outside the universe? This possibility is very high. Perhaps we stand outside the universe and observe, you will also find that countless universes are suspended in a vast space like planets, and our universe is just a dust in it.
For parallel universes, there is another view that is multidimensional space. Some scientists believe that the universe is multidimensional and can be divided into 11 dimensions. And each dimension is composed of countless universes. We live in a three-dimensional universe, and there are also countless parallel universes coexisting.
These universes are equivalent to fragments one after another. Beyond the fragments is an even more expansive space. There are 11 such spaces, and each space represents a dimension. Each dimension is composed of countless universes, and each universe is independent of each other and does not interfere with each other. And all the 11 dimensional spaces together form a big universe.
The second point of view: there is nothing outside of the universe. This point of view is actually somewhat similar to the first point of view. They all believe that there is a vast space outside the universe, but the first view is that it is very lively and exciting outside the universe, and there are countless universes.
And this view holds that the universe is unique, and the existence of space outside the universe is only formed for the continuous expansion of our universe. We can use balloons as an analogy. For example, we put balloons in a huge space where there is nothing. Then continue to inflate this balloon, and it will continue to inflate.
As the balloon continues to expand, it also continues to occupy the limited space outside the balloon. Until one day, after it occupies the entire space, it will not continue to expand. The space outside the universe may be similar to this. It is just a vast space with nothing. The purpose of existence is to allow our universe to continue to expand.
If this view is correct, then the expansion of the universe has a limit. When it fills the space outside the universe, it will stop expanding. And to prove this point of view, it is naturally impossible for humans to do it now, but in the future with the continuous advancement of science and technology, perhaps we have the ability to observe the expansion of the universe.
If one day it is discovered that the universe has stopped expanding, does that mean that there is not enough space outside the universe for it to expand? Of course, this is just a guess. If the universe stops expanding, there may be other reasons, such as insufficient dark energy for it to expand.
The third point of view: Our universe may be a living body, and an even more extreme point of view is that the universe may be part of a vast living body with neurological disorganization. This view makes us feel scared. The conjecture that the universe is a living body is not put forward by the people who eat melons, but a conjecture put forward by scientists.
In fact, as we continue to improve our understanding of the macro and micro, the macro and the micro are also relative, the end of the macro is the micro, and the end of the micro is also the macro. From the perspective of the universe, when the universe shrinks to the size of the solar system, the earth may only be as large as a particle.
Perhaps in the eyes of many people, the universe is vast, and it cannot be a life form. But if there is really a vast space outside the universe, then the universe is actually very small. Mankind has begun to vigorously research nanotechnology. If nanorobots appear in the future, they can enter the interior of mankind.
If we walk into the human body from the perspective of a nanorobot, you will also find that the human body is a very vast space. If the cells inside the human body are conscious, they will also think: What will happen outside the world in which we live? They may also be full of various conjectures about the world in which humans live.
The above three viewpoints are some simple descriptions of possible situations outside the universe by scientists. Of course, these are only current conjectures. We still cannot see the scope of the entire universe, nor can we observe the edge of the universe. Only one day, when we can see the edge, may we hope to see the tip of the iceberg beyond the universe.
