Exploring the Existence of Extraterrestrial Civilizations with the Liquid Universe Model

Authors: Zhi Cheng

According to the liquid universe model, some of our existing ideas about extraterrestrial civilizations may need to be revised to some extent. Considering that the development of biological civilization needs to last for a relatively long time, for example, from the formation of protein on the earth to the age of dinosaurs, to the emergence of humans, it has continued for billions of years. And this time beginning was shortly after the birth of the planet. Therefore, the appearance of life on a planet is closely related to the life of the entire galaxy. Considering the liquid universe model, there are two cases. One is that the center of the galaxy is a black hole, which will continuously absorb the surrounding masses. The other is a white hole, which constantly throws masses to the outside. A common feature of both cases is that the outer masses of the galaxy exists for a long time, while the inner masses of the galaxy exists for a short time. Combining the time required for the evolution of living things, it can be judged that if advanced biological civilization is to be evolved in a galaxy, the more proliferating planets should be closer to the periphery of the galaxy, the longer the development time, the higher the civilization. According to such a conclusion, it means that at least in the Milky Way, the biological civilization on Earth should be in a very advanced position. This article also briefly discusses the various ways of detecting extraterrestrial civilizations, and gives some suggestions for the detection of extraterrestrial civilizations.
