People must colonize another planet within the next 100 years, otherwise they will face the threat of extinction as a species. This was stated by the physicist Stephen Hawking, reports LIGA referring to the CNBC channel. "With climate change, possible asteroids, epidemics and population growth, our own planet is becoming increasingly dangerous," he said.. The scientist noted that the probability of a catastrophe on the planet Earth is almost one hundred percent in the next 1,000 or 10,000 years, so people should colonize other space objects so that a catastrophe on Earth does not mean the end of the human race. On April 28, 2017, Hawking warned that increasing the power of artificial intelligence on the one hand helps people solve many problems, and on the other - can lead to human degradation.
