Harry Coumnas believes that mankind is surely in danger of being eliminated from this universe. He has researched a lot and finally come to this that there are some catastrophic factors that could doom humanity. These factors include human-triggered cataclysms, natural disasters, and greater forces which can be directed against us. For more than 500,000 years, the humans have roamed the land, made complex languages, built cities, and also sent robots to far distant planets. Harry Coumnas, who is a widely popular Futurist, conducted a research in which he found that nearly 99 percent of all species who established their habitat on this planet have gone extinct, that also include all of our hominid ancestors. Following are the reasons, which he believes that could be responsible for the fall of the world.
Natural Disaster - Asteroid impact is the top reason why it should be taken seriously. There is a great chance that a cosmic interloper will hit Earth, and according to Harry's research, we won't have to wait millions of years for it to be a reality. History is full with such kind of events, and one of them occurs in 1908, when a 200-foot-wide comet fragment pierced through the earth's atmosphere and exploded over the Tunguska region in Siberia and Russia. Astronomers believe that similar-sized events occur every one to three centuries.
Gamma-ray Burst - Another reason which Harry Coumnas thinks could be possible, is a Gamma-ray burst. Once a day or so, one would see a bright flash appear in the sky for a short time, which outshine everything else, then goes away. According to him, these gamma-ray bursts originate in far distant galaxies and are 10 quadrillion (a one followed by 16 zeros) times more powerful than the sun. Once the burst starts, it is for sure that, there would be no escaping from its fury. The atmosphere of earth will surely offer the initial protection from most of the burst's deadly X rays and gamma rays, but at a cost.
