This article will reveal ten cool space science knowledge for you, and take you to appreciate the wonders of the universe.As we all know, 太空探索 The emergence of the market is worthy of many people’s attention, which has aroused the waves of the whole market. https://www.zhanmeng.net/

　　Black hole: the mysterious devourer in the universe. A black hole is a celestial body formed by the collapse of a star. Its gravity is extremely strong, and it can devour everything close to it, even light cannot escape. At present, scientists have discovered many black holes, but their internal structures remain a mystery.

　　Big bang: the starting point of the birth of the universe about 13.8 billion years ago, a huge explosion triggered the birth of the universe. This explosion is called the “Big Bang”. It produced countless stars, planets and other celestial bodies, which made up today’s universe.

　　Dark matter and dark energy: invisible forces in the universe. Dark matter and dark energy are two mysterious components in the universe. Although they cannot be directly observed, scientists believe that they account for about 95% of the total mass of the universe and play a key role in the evolution of the universe.

　　Multi-Universe: Endless Possibilities Multi-Universe Theory holds that our universe may be just one of countless parallel universes. These universes may have different physical laws and historical processes, which constitute endless possibilities.

　　Astronomical unit: The astronomical unit (AU) is a unit for measuring the scale of the universe. 1 AU is equal to the average distance from the earth to the sun, which is about 1.496〜 10 8 km. Through astronomical units, scientists can describe the distance between universes more conveniently.

　　Gravitational waves: ripples in the universe. Gravitational waves are spatial distortions caused by the movement of celestial bodies, and spread outward like ripples in water. In 2015, scientists directly observed gravitational waves for the first time, which verified the prediction of Einstein’s general relativity.

　　Cosmic background radiation: the oldest light in the universe. Cosmic background radiation is the faint light left after the Big Bang. It is the oldest “relic” in the universe. By studying the cosmic background radiation, scientists can understand the early history and evolution of the universe.

　　Tianwen-1: A milestone in China’s exploration of Mars. Tianwen-1 is a Mars probe independently developed by China and launched in 2020. It has successfully accomplished the three major tasks of Mars’ circumnavigation, landing and patrol, and created a new glory for China’s deep space exploration.

　　Alien life: Other life forms that may exist in the universe With the continuous exploration of the universe, scientists are more and more interested in the possibility of alien life. Many scientists believe that there may be life forms different from life on earth on other planets in the universe.

　　Mankind’s space exploration: a journey across the stars Since the 20th century, mankind has made great progress in the field of space exploration. From the Apollo 11 landing on the moon, to the establishment of the International Space Station, and then to the exploration of Mars, human beings have been constantly expanding their cognitive boundaries of the universe.

　　We can see the mystery and mystery of the universe through these ten cool knowledge of space science popularization. And human exploration of the universe will continue endlessly. Let us look forward to more amazing discoveries about the universe and reveal more secrets about the universe.
