After the sun stops attracting, the earth will no longer rotate according to the original orbit, but will go out and become a wandering earth, wandering around aimlessly in the universe, without the sun, the surface temperature of the earth There is also a sharp drop, which creates ice.
The earth’s core can preserve 80% of its temperature, so although the surface temperature is very low, humans can still survive on the surface temporarily, and when plants lose light and cannot perform photosynthesis, large areas will wither and die .
After the sun stops burning for a week, the temperature on the surface of the earth will drop to about minus 100 degrees. In this case, the ocean will freeze like the north and south poles. A little life can survive at the bottom of the thousand-meter depth.
At the beginning, humans could survive on the surface with the help of heating equipment, but when the temperature dropped to minus 100 degrees, the heating equipment lost its function. underground. If you want to survive underground, you need to use large-scale equipment to dig and drill holes. After breaking through the thick ice, humans can temporarily survive with the help of heating equipment, but there are still many problems that have not been resolved.
Conditions needed to survive underground
First of all, the most important thing is to ensure that there is enough energy for the operation of various equipment. If the energy problem is not solved, even if it is underground, it will be frozen to death by the continuous low temperature; the second is to continue digging underground. If it is too shallow, it will not work at all. The third is the need for sufficient food, which can support human beings to survive underground for about a year.
Moreover, due to the large population, ordinary heating equipment will not work at all, so during this year, new energy sources must be researched to withstand the severe cold.
