Features: The exploration of dark matter is one of the most important topics in current physics. The authors guide us on a journey of dark matter exploration in plain and easy-to-understand language. There is now conclusive evidence that more than 90% of the mass in the visible universe is composed of matter invisible to telescopes. The gravitational effects of this "dark matter" determine the evolution of all celestial objects we observe—galaxy clusters, galaxies, and stars. Research on dark matter will help us understand the fate of the universe and the formation of all observed structures. The exploration of dark matter is a crucial part of modern physics and astrophysics, as well as one of the most important topics in current physics. It involves the entire field of particle physics and cosmology. There is now conclusive evidence that more than 90% of the mass in the visible universe is composed of matter currently invisible to telescopes, believed to be made up of some new type of fundamental particle. The gravitational effects of these "dark matter" determine the motion of stars in galaxies, the motion of galaxies in galaxy clusters, and ultimately the evolution of all celestial objects we observe in the universe—galaxy clusters, galaxies, and stars. However, it is known that dark matter alone is not sufficient to fully explain the observed expansion of the universe. Therefore, a more extraordinary argument is that most of the energy in the universe may be related to the vacuum, and not only that, this energy is accelerating the expansion of the universe over time! Research on dark matter will help us understand the fate of the universe and the formation of all observed structures. As an expert in this field, the author avoids overly complex theories and instead guides us on a journey of dark matter exploration in plain and easy-to-understand language. The author does not arbitrarily tell us what is right or wrong; instead, he presents us with a logical process and some hypotheses that arise during this process. Then, he allows readers to judge for themselves what to accept.
