We are no longer alone. In the next 654.38 billion years, the universe may usher in a big bang!

According to the current research, the life span of the universe has lasted for nearly 654.38+03.9 billion years, while the history of mankind is only 2 million years, which can only be regarded as a moment of the evolution of the whole universe. The vast universe sets off our earth so small, but it is this small planet that breeds colorful life forms and splendid human civilization, which is a miracle in the universe.

Then, we can't help asking, is the earth the only living planet in this vast universe? Is human civilization the only advanced civilization in the universe? Or, in this vast universe, is there any life similar or similar to ours? Is there a civilization like ours? Is there a civilization more advanced than human civilization? Will we be invaded by alien civilization one day or launch a war of interstellar aggression? These problems are extremely fearful, leading to our infinite imagination and a lot of sense of crisis.

According to scientific logic, these are all possible. But the strange thing is, why is our earth so quiet until today? After the efforts of so many generations, our science and technology have developed, but we still haven't found any signs of life except life on earth. Are we really the only life form in the universe? Does the whole universe really exist only for us? Is the meaning of the existence of the universe all on us?

It has been explained that the earth may be the earliest life form in the universe, and human civilization is the earliest civilization in the universe. There are several possibilities for this explanation. First, human civilization may be replaced by other civilizations. This substitution may come from some existing life form on the earth, just as humans replaced dinosaurs at the beginning; Another possibility is to be invaded by alien creatures, star wars will occur, and finally human beings will be replaced by more advanced alien civilizations. Second, there are still evolving life forms in the universe, and aliens can't find them because they haven't been born yet. Maybe one day, they will have their own civilization like human beings. These beings may never come into contact with humans on earth, and they will live in peace. It's entirely possible. Maybe it has already happened.

The conditions for the birth of life, especially intelligent life, are very harsh, which is not difficult to explain why we haven't found aliens yet. The emergence of human civilization benefited from the collision between heaven and earth 65 million years ago. Without that collision, dinosaurs would rule the earth in a narrow living space, and human beings might never evolve, let alone produce civilization. It can be concluded that there may be life on a planet, but there is no civilization, which may explain why we didn't get a response when exploring alien civilization, because there is no civilization, but it doesn't mean there is no life. There may be a planet similar to the earth with lower life on it, which provides infinite possibilities for us to realize interstellar migration.

Scientists predict that the next 1 100 million years may usher in the best period of life incubation in the universe. At that time, various life forms may appear on different planets in the universe. These life forms do not have to be inseparable from water and air like human beings, nor do they have to eat like human beings. They may live in an environment like the moon or Mars, and live by eating some minerals every day. The shit they pull out may be gold. In fact, this is not impossible, because there are indeed creatures on our planet that do not need oxygen and water.

No matter whether there are other life forms in the universe, we humans will be unique, because the earth is unique, the sun is unique, and even the Milky Way is unique in the universe. Therefore, even if there is extraterrestrial life, it will certainly not look like human beings. They may not have men and women like humans, and their children and grandchildren may not be conceived in women's wombs like humans, but may grow on trees like apples. While the universe is welcoming the Big Bang, it will also usher in a period of civilization in which a hundred flowers blossom. This may be what we like to see, because by that time, we will no longer be lonely, and our civilization will rely on and compare, so that we will have a sense of accomplishment and superiority.
