Will mankind perish? The development prospects of mankind are a matter of concern to everyone. Throughout history, predictions of the so-called "end of the world" have been one after another. In fact, in the history of biological evolution, there have been many large-scale extinctions, of which the two extinctions 250 million years ago and 65 million years ago were particularly serious.
Research by Campbell, a researcher at the Institute of Geosciences at the National University of Australia, showed that 250 million years ago, Siberia had the largest lava explosion on earth to date, causing the destruction of 95% of animals and plants. 65 million years ago, a near-Earth asteroid with a diameter of more than 10 kilometers hit the earth, and this impact directly led to the extinction of dinosaurs.
Gort III, an astrophysicist at Princeton University in the United States, published an article in the British journal Nature on May 27, 1993, entitled "The Implications of the Copernican Principle for Our Looking to the Future." He proposed the following equation based on probability theory: (1/39) × past time <future time <39× past time. The literature he quoted reported that taking the average time when most species appeared on the earth: 1 million to 11 million years, of which humans have lived for about 2.5 million years, he inserted this into the above equation and obtained: (1/39) × 2.5 million years <Future time <39× 2.5 million years. It can be estimated that humans may become extinct between 641,025 and 97.5 million years in the future, with a probability of 95%. Anyway, humans will still have a long time to live!
