Comprehensive News of Overseas Chinese News Network Scientists of the National Aeronautics and Space Administration of the United States recently published a research paper saying that if there are other intelligent creatures in the Milky Way, they are either too "young", too far away from the earth, or have died out on their own, so they have not been discovered by humans.

ETtoday quoted the Daily Mail in Taipei as saying that this paper was written by researchers from NASA's Jet Propulsion Laboratory, California Institute of Technology and San Diego High School, and has been published in the paper preprint database arXiv. Using the improved Drake equation, researchers speculate that alien civilization may be born in the Milky Way 8 billion years later, but then it will be destroyed in its own developed technology, while other alien life may be too young for human observation.

Drake Equation was written by American astronomer frank derek in 196 1 year. This equation comprehensively considers the number of stars, the generation rate and the proportion of planets that can develop life to estimate the number of extraterrestrial civilizations in the Milky Way.

The study said, "If intelligent life has the possibility of self-destruction, it is not surprising that human beings have not found alien life. Other intelligent life may be too' young' or too far away from the earth. "

This study explains that the length of biological evolution is largely similar to that of the earth, and "self-destruction" is often ignored by scholars. The results show that intelligent life may be common in the Milky Way, but the earth is too far away from them.

This study points out that by evaluating the changes of complex life in the Milky Way in a specific time range, people can understand the "rare earth hypothesis" of the origin of life. This hypothesis holds that the formation of complex life requires the combination of various accidental conditions, so complex life is rare, which is Fermi paradox. "If alien life is common, why don't they appear?" Provides a way of thinking.

According to NBC's previous report,1February 8, Israel's Yediot Izvestia quoted Heimeish, the former head of Israel's space security project, as saying.

Haim Ashid's words revealed a shocking news: The American government signed an agreement with aliens, who are studying the "structure of the universe" and set up a secret underground base on Mars, where there are representatives of American astronauts and aliens. President Trump knew about the agreement and almost leaked the news. The White House did not respond to the news. (End)
