In the 1970s, the “zoo” hypothesis emerged that humans were not alone in this vast universe. According to this hypothesis, the Earth is like a “zoo”. Humans and all creatures are under the watch of alien – “galactic animal keepers”.Extraterrestrial beings deliberately evaded human observation and search. Therefore, we have tried to search for extraterrestrial life, but there are still no results.If the “zoo” hypothesis is correct, then people alien deliberately isolates us from other civilizations in the galaxy.However, we should not be hasty to despair. Because, humans have been searching for alien life for about 100 years. Meanwhile, Earth has been around for more than 4.6 billion years. Therefore, we need to be more patient in our search for the refuge of extraterrestrial civilization.Another theory is that advanced civilizations on other planets may have stalled or died before having a chance to meet with humans on Earth. This is thought to be the reason why we have yet to find alien life.According to this hypothesis, when the civilizations in the universe grow in size and technology reach their final threshold of development, that is when they are also in crisis.Because, when it reaches that stage, development can no longer keep up with the demand for energy. The result of the crisis was the collapse of civilization.Another theory that has caused much public debate is that the universe is so vast that it could take up to 400,000 years for a signal sent by one advanced species to reach another.That is a very long time compared to the lifespan of humans on Earth. Even when received, it is difficult for humans to decipher the content of the signal sent to us by aliens because the two civilizations may have a large difference in technological development.So, over the years, humans have sent many signals into space in the hope that aliens will receive and respond. However, until now, the scientific community has not received any response from extraterrestrial beings.Invite readers to watch the video: The US announced seeing more than 120 UFOs in the past 2 decades.
