What if the sun disappeared

What would happen to the earth if the sun suddenly disappeared? At this moment, the earth is no different from usual. After 8 minutes and 20 seconds, the last beam of light reached the earth, the sky suddenly darkened, and eternal darkness instantly enveloped the entire earth. The sun disappears for 10 minutes, and the moon disappears from our sight forever. Half an hour after the sun disappears, the Earth's magnetic field changes significantly, and if you're lucky enough to see bright auroras in the night sky.

The sun disappeared for an hour, and the surface temperature dropped rapidly, but the earth's inner core still radiated strong heat, and network communication began to gradually break down. The sun disappears for a day, and the dawn that mankind has longed for has not come and will never come. The world began to hold an emergency meeting to discuss the next steps, and top experts carried out scientific research to try to find out the truth of the disappearance of the sun. After the sun disappears for a week, plant photosynthesis stops completely, and oxygen is not produced. 90% of the plants on the earth will disappear one after another due to cold and insufficient light. The power plant also ran out of the last fuel, a lot of electricity and heating facilities were interrupted, the surface temperature of the earth gradually dropped to minus 10 degrees Celsius, and human beings finally realized the seriousness of the matter, and began to wear cold protective clothing to find a new home, Some people took a submarine to dive into the deep sea, and some people warmed up in hot springs near the volcano.

The sun disappeared for a month, but the miracle did not occur. At this time, the surface temperature of the earth had dropped to minus 20 degrees Celsius. Due to the disappearance of plants, herbivores began to gradually disappear, but carnivores could persist for a while. The surface of the ocean has been covered with ice, and some marine life has begun to die out. Half a year after the sun disappeared, due to the long-term lack of sunlight, the surface temperature of the earth has dropped to minus 50 degrees Celsius, and the entire planet is almost covered by ice. A year after the sun disappeared, the earth's surface temperature has dropped to minus 100 degrees Celsius, but due to the impact of submarine volcanic eruptions, in addition to all the ice on the ocean surface, the ocean floor is still in a warm liquid state. And all the surviving life on earth is deep in the dark seabed at this time, including bacteria and some unknown creatures. The sun has disappeared for 10 years, and the surface temperature of the earth has dropped to minus 200 degrees Celsius. At this time, except for bacteria that can withstand extremely low temperatures, all life on earth may no longer exist.
