Even though human science and technology are very powerful today, they cannot give accurate answers to many questions. Not to mention what the end of the universe is, humans cannot even explore the meaning of the existence of the earth itself and some secrets inside the earth. For example, what exists in the glaciers of the Arctic, Southern and Southern Poles, the mysterious Bermuda Triangle , and why did the prehistoric civilization disappear?
Answers to questions may be very important to humans, but in fact, when humans think about some problems, they may not be the answers to these questions, but some things they have gained in the process of discovering the problems. Either the development of science and technology , or the satisfaction of human curiosity. The existence of human beings and the existence of the universe may have been determined.
The operation of all things in the world has its own rules. To put it in a very inappropriate metaphor, it is not that the time has not arrived. The existence of any thing and the occurrence of any event have its own rules. Even something as illusory as the universe has discovered his unique operating rules in the exploration of him by humans. But the development of mankind cannot be explored entirely through rules. Not to mention what the end of the universe is, the answer to this question is still very far away from the current human beings.
Under the existing technology, the observable diameter of the universe is about 93 billion light years. This is just a rough estimate. With the continuous development of human technology in the future, there may be greater breakthroughs in understanding the diameter of the universe, which means that humans must always maintain a humble heart in front of the universe. The current strength of human technology is only relative to the ignorance of human beings. Not to mention that the earth is so small compared to the universe. Just the gap between humans and the earth, humans’ understanding of the earth has made it impossible for humans to take care of everything else.
What is the end of the universe, and what is the meaning of human existence? This is a philosophical thinking category and a discussion of people's worldview and methodology. But if humans can't even figure out the earth, it's too early to start thinking about what is possible at the end of the universe, or even meaningless. Instead of pursuing those illusory things, it's better to be down-to-earth and solve some of the problems that are currently plaguing humanity, such as the COVID-19 pandemic.
