Human beings are the most intelligent life on earth. Since their birth, human beings have been constantly exploring the mysteries of the world. After thousands of years of scientific and technological exploration, human beings are finally able to leave the earth and explore the universe. This shows that the speed of human technological development is still very fast. Quickly, when humans step out of the earth and see the universe, their curiosity is attracted by the vastness of the universe. Human beings want to know how big the universe is? In addition to life on earth, is there also alien life in the universe? With these questions, mankind embarked on the path of exploring the universe.

According to the research of scientists, we can know that the universe was born 13.8 billion years ago. 13.8 billion years ago, a singularity exploded. The singularity is an infinite mass, infinite energy, infinite density, and heat. This point is produced after the explosion of an infinitely large and infinitely small point. After the explosion, the universe rapidly expanded in all directions. It took 13.8 billion years for the universe to expand into what we see now. The celestial bodies in the universe were all formed after the Big Bang. Our earth is a part of the universe. There are too many planets in the universe to count, but the biggest difference between the Earth and other planets is that life was born on the Earth.

The emergence of life has added a lot of color to the planet Earth, especially after the emergence of human beings, which has unlocked many mysteries on the Earth. Many scientists believe that the reason why the Earth can give birth to life is mainly because the Earth meets the requirements for the birth of life. Basic conditions, these basic conditions are: suitable temperature, sufficient air and abundant water resources. If a planet can meet these basic conditions, then this planet The possibility of life being born on a planet is also very high, but so far, scientists have not found alien life in the universe. In order to explore alien life, scientists have also made a lot of efforts. Once, 45 years ago, Scientists launched the Voyager 1 probe outside the solar system. The purpose of launching the Voyager 1 probe was to let it fly out of the solar system and explore the mysteries outside the solar system. However, after so many years, the Voyager 1 probe has not yet Didn't fly out of the solar system.

Scientists have calculated that according to the current flying speed of the Voyager 1 probe, it will take at least tens of thousands of years to completely fly out of the solar system. For humans, tens of thousands of years is really too long. The life span is only a few decades. This This means that humans may never be able to get out of the solar system. At present, human exploration of the universe basically relies on astronomical telescopes . The diameter of the universe that humans can currently observe is about 93 billion light-years, and this range is not the universe. In all its scope, the universe may be bigger than we think.

Until now, our universe is still expanding. At the beginning of the 20th century, American physicist Edwin Hubble discovered when observing the Andromeda Galaxy that the spectrum in the galaxy was moving away from us. This phenomenon indicates that these galaxies are moving away from each other After we saw this phenomenon, Edwin Hubble put forward a bold conjecture, that is, our universe is still expanding. After this idea was put forward, many scientists could not believe it. After all, before this, scientists We have always believed that our universe is static, so many scientists have conducted observations of the universe, and finally found that Edwin Hubble's theory is correct.

Edel Hubble's theory not only gives humans a new understanding of the universe, but also makes humans feel very desperate. After all, humans have always wanted to know how big the universe is since they walked out of the earth? If the universe continues to expand, then we may never be able to find the edge of the universe. Seeing this, I believe many people will have a question, that is, where is the driving force for the expansion of the universe? Many scientists believe that there should be a mysterious substance in the universe that we cannot see or touch. This substance is called dark matter . Scientists believe that dark matter does not chemically react with any other matter, so we cannot see it. Can't even touch them.

Dark matter can release a mysterious force. This force can not only promote the continuous expansion of the universe, but also control the movement of celestial bodies. Currently, scientists are also actively searching for dark matter, but after so many years, scientists have not discovered it. Dark matter, this shows that dark matter may be more mysterious than we imagined. How many secrets are hidden in the universe that we don’t know? At present, humans do not know. Even the once famous physicist Einstein believed that our universe was created by God. In his later years, Einstein also wrote a memoir, which roughly means: God created our world and God lives in our universe. What exactly is God in Einstein’s eyes?

Scientists don’t know yet. Maybe in the eyes of scientists, God is not a god, but the basic particles that make up the universe. Just like once Professor Yang Zhenning was asked in an interview: Do you think there is a God in this world? ? Professor Yang Zhenning replied: If the God you call is human-shaped, then I think there is no such thing. If you ask me if there is a creator, then I think there is, because everything in the universe is not accidental. Although scientists don’t know yet, most scientists believe that the God who created the universe must not be the god we think of, but what exactly is it? Scientists now don't have an accurate answer.

However, the editor believes that in the early days of the birth of the universe, there must have been an initial force that prompted all of this to happen. Who created this initial force? Now scientists don’t have an accurate answer. Maybe this initial force is the most basic particle. Scientists have found many basic particles in the universe, but this is not enough. In addition to these basic particles in the universe, there must be other Due to the current limited level of human science and technology, it is basically impossible to unlock all the mysteries of the universe. However, human beings are the most intelligent life on earth. Human science and technology are constantly improving. In the future, as human beings The development of technology. Maybe we can unlock the mystery of the birth of the universe. I hope this day will come soon. Is there anything you want to say about this?
