Dark Day

What would happen to human civilization if the sun suddenly disappeared for twenty-four hours? This is not a fantasy, but a real countdown to doomsday. When the star that had burned for 4.5 Billion years disappeared from all observations without warning, the earth fell into unprecedented darkness and cold. Eight billion people had no time to panic, so they had to fight for a chance to survive in a desperate situation of minus 150 degrees Celsius. Gravity disappears, the earth flies out of orbit; light and heat are cut off, and the atmosphere begins to condense. From astronauts on the International Space Station to financial analysts at Beijing International Trade Center, from survivors in underground bunkers to scientists struggling to calculate orbits - everyone is witnessing the collapse of civilization at a speed visible to the naked eye. But the sun will return eventually. But what came back was not salvation, but a more cruel judgment: the earth was pushed out of the habitable zone, its orbit became an extreme ellipse, there were 620 days a year, and the temperature difference between day and night exceeded 100 degrees. Humanity was forced to retreat underground, learning how to live again in the dim light of nuclear reactors and the residual warmth of geothermal heat.
