Where Are The Intelligent Aliens And Why Cant We Find Them

For more than 50 years people have been scanning the night sky in the hope of finding evidence of intelligent life beyond Earth. By monitoring the galaxy for signals in light or radio wavelengths, scientists are searching for signs of technologically advanced alien beings. Beings that we may one day be able to communicate with. According to research, the Milky Way galaxy is approximately 13.2 billion years old and contained within it could be tens of billions of Earth-like planets orbiting within the Goldilocks zone of their stars. Yet Earth is, at the time of making this video, the only planet in the universe we know of that harbours life. So with the galaxy being as old as it is, and so many potential habitable exoplanets out there, where are all of the intelligent aliens? Although it might seem unlikely in a galaxy full of potential planets, we may well be alone. The appearance of life might arise, but the evolution of technology might be completely unique to our planet. On Earth, there are many intelligent species, from dolphins to elephants, but in millions of years of life, only one species has become technologically advanced, human beings. So maybe the appearance of intelligent life is extremely unlikely, and that aliens are simple forms of microbes or cosmically quiet animals with no technological abilities. The distances in our universe are incredibly vast. NASA estimates that the Milky Way galaxy alone is about 100,000 light years across. Within this huge cluster of stars could be thousands of extraterrestrial civilisations, but our nearest extraterrestrial neighbour might be very far away. Because of these vast distances, contact between our potential galactic cousins could be extremely difficult and rare, due to the time it takes a signal travelling at light speed to reach us or for our presence to be detected by them. The sheer size of the Milky Way also means that precisely listening for alien signals becomes very difficult, and this means that we may never make contact, even if intelligent extraterrestrial life is common throughout the galaxy. Although humans are clearly the most intelligent beings on Earth, we may be centuries behind extraterrestrial civilisations regarding technology. If this is the case, then our chances of detecting intelligent alien life could be drastically reduced or completely out of our reach. Currently, scientists are scanning the skies for exotic radio signals from other civilisations, but these otherworldly beings may use advanced communication technologies that we currently do not have the scientific knowledge to make or detect. Potentially the most unsettling of all the theories regarding the existence of alien life is the idea that intelligent, technologically advanced beings eventually self-destruct. This might sound odd, but it is a possibility that a civilisation unintentionally destroys itself, using weapons of mass destruction, unmanageable planetary pollution, or maybe even the inevitable discovery of an uncontrollable energy force, for example. If this scenario is correct, then all advanced civilisations would eventually disappear, and this would then mean that the future of human beings is not only a lonely one, but also a deadly one. It is a possibility that the galaxy is full of advanced civilisations, and that the highest developed of them have been communicating, potentially setting out galactic rules. If this is the case, it is conceivable that they would leave the lifeforms deemed primitive or lesser alone, only to be watched from a distance. We could, in the eyes of a highly advanced alien, be potential for the future, but need time to evolve and advance our technology until they feel we are ready to be accepted into some sort of galactic alliance. Now that would be an awesome way to discover aliens. I really hope you enjoyed this video, remember to hit that like button and subscribe for much much more to come.
