Would Earth survive without the Sun? It seems unlikely. The heat from the sun helps to keep the earth warm and protects it from damage. If the sun were to disappear, the temperature of the Earth would drop dramatically, and humans on the planet would die. The seas would freeze over within two months, and the surface of the planet would become a barren wasteland. But a nuclear energy dome could keep the Earth alive for a long time.
Plants on Earth would not survive without the sun because the heat from the sun is required for photosynthesis. The light from the planets would reflect back to the Earth after an hour. In the first week, plants and animals would die. However, large trees and other plant life could last for decades. The death rate of all other animals would be high. Only scavengers and other non-living creatures could survive in the dark, and their survival depends on the timing and the linear course of the sun.
If the sun stopped emitting light, Earth would be able to support animal life. Eventually, life would cease on Earth, and chemolithotrophic organisms could survive. Afterward, the surface of the Earth would freeze solid. The sun’s heat and light from geothermal vents may reach the deep ocean, where life would be impossible. But a geothermal vent could not survive for long.
The Sun’s light is essential for life on Earth. Without it, we would be unable to sustain human life. Our atmosphere would be a peaceful glow, and electricity would continue to work. And as long as the Sun stays on course, we could grow plants and animals without light. But living in a world without the sun is impossible. So, what would the future hold for the planet? The answers are not all that clear.
As long as the Sun is present, the earth’s temperature would remain stable. It would remain in a stable orbit around two stars. In addition, if the sun were to disappear, the Earth’s temperature would plummet to minus 100 degrees. The water would be frozen over and humans might have to adapt to living in the dark. The only solution is to build artificial light for plants and humans. But would the planet survive without the sun?
The Sun is the main source of life on Earth. It is the only way for plants to grow. Without the light, they cannot photosynthesise, and therefore wouldn’t be able to survive. And if the sun didn’t exist, the planet would be a hot ball in a pool. If the sun did not exist, we wouldn’t be able to grow plants. But our species wouldn’t last long without sunlight.
If the sun was gone, would Earth still exist? The answer, of course, is a complicated question. If the sun was gone, would the planets still exist? No. Pluton is the only known object to be exempt from solar radiation. Its mass is about 2/3 of the mass of the sun. But if the sun was not around, there wouldn’t be any way to grow life on the planet.
According to one theory, if the sun isn’t there anymore, the planet would be in a perihelion-sized sphere in the solar system. The sun is a major part of the solar system, which is the centre of gravity. The planets aren’t quite the same size, and the sun’s gravitational pull may have caused the planets to collide. This is the same scenario that might happen with the Earth.
The sun keeps the Earth in orbit, providing energy and heat. If it goes away, the Earth would be stranded aimlessly in the solar system. But the molten planetary core is filled with energy, enough to keep human life on Earth. The molten core will keep us alive for thousands of years. If the sun were to burn itself, would life on Earth survive? This question is a fascinating one to consider.
