We rush about for three meals a day, worry about daily necessities, worry about children's education ... worry about minor contradictions and problems, and deal with various relationships in human social activities ... We only live in our own world, and rarely go out of human limitations to see the world, the stars and the vast universe ... Have you ever thought about the universe with your heart? And what kind of role are we in the endless universe?
? Modern astronomy believes that the universe is the sum of all time, space and matter.
? According to our prediction, the universe has existed for 654.38+03.8 billion years. Our earth, to the solar system, the milky way, the local group of galaxies. The Milky Way is just one of thousands of copies in virgo supercluster. From this ratio, every point we see is a galaxy, and each galaxy contains billions of stars. And countless planetary worlds. However, virgo supercluster is only a small part of our universe ... this is the largest universe we know-a huge network of galaxies. ...
? A big net, in which we just can't even see ourselves? The earth can't see it? Slowly replenish the brain ...
? Indeed, we are really a capitalized "nothing"!
? Have we ever existed for the universe? Does our existence make sense? What did your existence leave behind? The answer ... no.
? Imagine, from the very ancient chaotic universe138 billion years ago to the very distant future. In the long river of time connecting history and the future, we humans have almost no trace of existence. Human existence is only a tiny part of the universe. Time and space, there are many times and spaces that we can't see, and there are intangible worlds that we can't understand and imagine. Human intelligence is extremely limited.
? After reading it, it's like traveling to the universe, imagining this ship of science. Not limited by time and space, from the smallest to the infinite, from the starting point of time to the distant future, swim in the combination of time and space. In addition to contacting our unknown galaxies, we also contact the known earth, contact creatures living in fire and ice, and explore eternal galaxies. Understand atoms as big as stars. There is a universe smaller than atoms. ...
? After reading it, there is only one feeling. We humans are so small that we can't see the dust. Don't say that human beings, the earth and the sun are all small.
? Let's see what the ancient earth was like.
? This is what the earth looked like 250 million years ago. A vast ocean, a small piece of land, all deserted. There is no sign of life. How young and beautiful the earth is, it indicates the explosion of vitality. Like an infant. What we see is a beautiful sleeping side face.
? This is what we imagined 250 million years later according to scientific basis. Prosperous, prosperous and bright. Humans are trying to prove their existence, and the earth is in contact with an extremely vast universe.
? In order to better imagine the history of the universe, scientists also cleverly made a proportional metaphor. If we put the universe in a calendar from the beginning to the present, until 65438+February 30, a planet that hit the earth changed all life on the earth and gave birth to signs of life. In the next 100 million years, dinosaurs were the rulers of the earth. However, the history of human existence is so short. For most of our human existence, such as the last 40,000 generations, our ancestors were vagrants. The vagrancy of 40,000 generations is the last hour in the cosmic calendar.
? All recorded human history took place at the last 14 second of the cosmic timetable. All the records about kings, battles, migrations, inventions, wars and love, as well as everything in history books, happened in the last few seconds of this cosmic calendar.
? At the last second, we began to reveal the secrets and laws of nature with science. The scientific method is so powerful that it took us only four centuries from Galileo's first sight of glasses to human footprints on the moon. It takes us through time and space. To observe our position in space-time of the universe. We have the idea of understanding the nature of the universe.
? Man can always work miracles. The power of life is infinite. In just a few thousand years, we are constantly exploring and verifying our existence, which is the best proof from seeking knowledge to knowing very well. We constantly use science to explore the mysteries of the universe.
? Fortunately, we still have the sun. We are in the solar system, and the sun is the wind and waves, providing energy for all living things on the earth's surface. The sun dominates all life on the earth.
? Humans are extremely small. Fortunately, we can survive. Feel all the mysteries of the universe The sun brings us hope.
