Humans are not alone? Expert: There may be at least 36 "alien civilizations" in the Milky Way
36 'alien civilizations' exist in the Milky Way
Since humans began to explore outer space, there have been more and more conjectures about outer space. For human beings, the universe is vast, so on the way to explore the universe, human beings still have a long way to go. Scientists have been exploring whether there is life in outer space a long time ago, but for the past so many years, this question has still not been answered, and in June 2020, the University of Nottingham in the United Kingdom also launched a related survey.
Scientists have tried many methods to explore outer space civilization, such as launching objects containing human civilization to fly into the universe, or designing probes to land on the moon or Mars to detect civilization, but there is still no answer. Therefore, the University of Nottingham in the United Kingdom also proposed to use the Greck equation to explore life in the universe. After studying the Greck equation, the scientist also concluded that there may be 36 alien civilizations in the universe.
The main principle of Greck's equation is "information transfer", which is mainly through the transmission of radio signals to outer space. Generally, the strength of the current will generate radio waves. When scientists add the modulated information to the radio waves, the radio waves can When it is launched into outer space, and the radio wave reaches the receiving end, the radio wave will cause a current to appear in the conductor, and finally the modulated information is extracted, and this is the whole experimental process.
Although the number of alien civilizations has been obtained according to the Greck equation, scientists are still confused about the development and evolution of alien civilizations. Because human beings have only been on the earth for tens of thousands of years, and human beings still do not understand a lot about the development and evolution of their own civilization. In addition, humans have the ability to explore the universe in the past few hundred years, and the history of radio waves is only more than a century, so it is normal for humans to not understand alien civilizations.
In the imagination of scientists, civilization is also divided into many kinds, among which human civilization is still relatively poor. According to the various historical data left by human beings, the technological level of alien civilizations may be beyond imagination, and even aliens no longer use radio waves to communicate, but instead use more advanced means of communication, which also leads to Scientists can no longer speculate about alien civilizations.
Scientists have not been able to prove the existence of alien civilizations before. Although the Greck equation has drawn some conclusions, this method is only a probability study. The universe is boundless in the eyes of humans, and there are many celestial bodies in the universe. According to existing scientific research, there are 400 billion celestial bodies in the universe. Therefore, it is almost impossible for humans to know how many civilizations there are in the universe. .
Humans have been exploring cosmic civilization since a long time ago. For example, in 1974, scientists received radio information from the globular cluster m13. After deciphering, they found that the received signal was - wow (wow). In 1977, Ohio State University also discovered a string of characters. Although it is impossible to explain what these characters are, in the cognition of scientists, this may be a signal from an alien civilization.
With the continuous development of science and technology, humans have also observed a lot of news of similar signals, but many cannot be answered. The universe is so large that it is unrealistic that only Earth has civilization among hundreds of millions of planets. However, it is still impossible for scientists to prove the existence of alien civilizations at the current level of technology. So as to whether alien civilizations exist, this road still needs to go a long way, and maybe in the near future, scientists can explain this problem.

Introduction: With the continuous development of the economy, various countries have gradually withdrawn the banknotes belonging to each country for the sake of economic stability. The banknotes implemented by various countries have their own values, but if we say that the world is universal, it should be gold. Gold is a very precious metal on earth, and because gold is relatively rare, its value preservation rate is also very high.

“Are You Dead?”: A New App Reflects the Loneliness of Young Chinese Living Alone
In China’s rapidly changing cities, living alone is no longer unusual—especially among young adults pursuing education, careers, and independence. But as solo living increases, so do concerns about isolation, safety, and what happens when no one is around to check in. Against this backdrop, a new app with a blunt, unsettling question—“Are you dead?”—has captured public attention and ignited debate. Despite its shocking name, the app is not designed to provoke fear. Instead, it aims to address a practical and emotional gap in modern urban life: how to ensure the well-being of people who live alone, and how technology is stepping in where traditional community networks have weakened. The Rise of Solo Living in China China has witnessed a dramatic shift in household structures over the past two decades. Urbanization, delayed marriage, rising housing costs, and changing cultural values have contributed to a growing number of single-person households, particularly among people in their 20s and 30s. For many young Chinese professionals, living alone represents freedom and self-reliance. It allows flexibility, privacy, and independence from family expectations. Yet this independence often comes with trade-offs: fewer daily social interactions, weaker neighborhood ties, and limited support in emergencies. In megacities like Beijing, Shanghai, and Shenzhen, it is increasingly common for neighbors not to know each other at all. In this environment, concerns about what happens if someone becomes ill, injured, or simply disappears from daily routines have become more pronounced. What the App Actually Does Despite its provocative name, the app’s purpose is surprisingly simple. It functions as a digital check-in system. Users set regular times to confirm they are okay—by tapping a notification or completing a brief check-in. If the user fails to respond after a certain period, the app automatically alerts designated contacts, such as friends, family members, or emergency responders. The stark question, “Are you dead?”, is intentionally designed to grab attention and prompt action. Developers argue that softer language is often ignored, while blunt phrasing cuts through digital noise and encourages consistent use. In essence, the app acts as a safety net, especially for people who live alone and may not have daily contact with others. Why Young People Are Downloading It The app’s popularity reflects deeper anxieties among young adults navigating modern life. Many users say they downloaded it not because they fear the worst every day, but because it provides peace of mind—both for themselves and for loved ones. For parents living far from their children, the app offers reassurance without constant phone calls. For users, it creates a sense of being quietly watched over, without sacrificing independence. Some users have also described the app as a form of emotional comfort. Even a routine notification can feel like a reminder that someone, somewhere, would notice if they vanished from daily life. A Name That Sparked Debate The app’s name has been its most controversial feature. Critics argue that the phrase “Are you dead?” is unnecessarily harsh and reflects a growing desensitization in digital culture. Others worry that such language could amplify anxiety rather than reduce it. Supporters, however, see the name as a reflection of reality rather than a provocation. In densely populated cities where people can go unnoticed for days or weeks, the question is uncomfortable—but relevant. They argue that avoiding blunt language does not eliminate the underlying problem of isolation. The debate highlights a broader tension in tech design: Should apps prioritize emotional sensitivity, or practical effectiveness—even if it makes people uncomfortable? Technology Filling a Social Gap The rise of this app points to a larger issue: technology increasingly compensates for weakened social structures. In the past, extended families, close-knit neighborhoods, and workplace communities naturally checked in on individuals. Today, those informal safety nets are often absent. Apps like this one are not just tools; they are symptoms of a society where digital solutions are replacing human presence. While convenient, this raises questions about whether technology is addressing the root causes of loneliness—or simply managing its consequences. Still, for many users, the app is not a replacement for relationships, but a supplement to modern life realities. Living Alone Does Not Mean Wanting to Be Alone An important takeaway from the app’s success is that living alone is not the same as wanting isolation. Many young Chinese adults value independence but still crave connection, security, and acknowledgment. The app’s routine check-ins, though minimal, provide a structured moment of contact. In a fast-paced, high-pressure environment, even small gestures of recognition can matter. This trend also reflects changing attitudes toward mental well-being and personal safety. Younger generations are more open to discussing vulnerability and using tools that previous generations might have dismissed. What This Says About Modern Urban Life The popularity of an app that asks such a stark question speaks volumes about the realities of contemporary urban living—not just in China, but globally. As cities grow larger and lives become more individualized, people are searching for new ways to ensure they are seen, remembered, and protected. The app’s success suggests that people are willing to engage with uncomfortable ideas if they address real needs. It also underscores the importance of designing technology that is honest about modern challenges, rather than masking them with euphemisms. Conclusion: A Wake-Up Call, Not a Warning While the phrase “Are you dead?” may sound alarming, the app behind it is less about fear and more about care. It reflects a generation navigating independence in a world where traditional support systems no longer function as they once did. Rather than signaling a morbid obsession, the app serves as a quiet reminder of something deeply human: the need to be noticed. In that sense, its blunt question is not about death at all—but about presence, connection, and the reassurance that someone would check if you were gone. As solo living continues to rise, tools like this app may become less shocking and more commonplace—symbols of how society adapts to changing ways of life in the digital age.
