If the sun is gone, how long will life on Earth survive?

For a week, because the sun is the main heat of the earth, after losing the sun, humans will soon freeze to death.

Everything on the earth needs sunlight to grow, and I personally think that if the sun is gone, life on the earth will not survive for a long time, at most a month. Because without the sun, many plants will die, humans will have no food, and human life will always be in a state of darkness.

If the sun were gone, life on Earth would survive for no more than a month, because plants could not photosynthesize and the world would fall into darkness, oxygen in the air would only decrease dramatically, and the temperature would continue to drop.

The vitality of the creatures on the earth is very tenacious, if there is really no sun, then the earth will be irreparably destructive, in the case of all living things are difficult to survive, it may not be a year for the creatures on the earth to survive, ushered in destruction, everything ceases to exist.

No ifs! The sun is forever, and the man is the sun.

Suppose that there is no sun at this moment, the earth will be dark, and of course you can rely on generators to generate electricity, but in fact, the entire earth has such a large demand for electricity, and power generation will not last long. The sun will give the earth temperature, and the earth will drop sharply without the sun's irradiation, and human beings may have to stay in an artificially warm constant temperature environment to avoid being cold to death.

Plants on the earth have no energy from the sun, cannot carry out photosynthesis, cannot synthesize and replenish energy to death, and plants all over the world will suffer the fate of death, and animals will die because of the mass death of plants. There is no way for humans to escape their doom, because of the lack of food, a large number of humans cannot survive. At the moment, the remaining human beings can only rely on technology, such as the ability to survive underground, as a way to resist the cold earth.

The moment the sun disappears, the solar system will collapse, and without the gravitational pull of the sun, the planets in the solar system will no longer circle around, but fly out along their original trajectory, and then move freely in the universe, and will collide with other planets and flying celestial bodies. The uncontrollable direction of flight and collisions with other celestial bodies in the universe are no longer something that human technology can prevent, and the fate of human beings is only death. Humans cannot immigrate to other planets with existing technology.

Humans certainly can't survive without the sun. There is no sun on it.

There is no light. The world will be pitch black, there will be no warmth, there will be no sun, everything will not photosynthesize, I will not grow, you can imagine that it will be all things dry up and decay. The same is true for humans.

Without sun, without light and warmth, how can human beings survive. It is a true truth that all things grow and look at the sun.

If the sun is gone, the moon is gone, there is no such world. Then there will be no tears.

This should not be, I have seen popular science before, if the sun disappears, then the temperature of the earth will drop to minus 200 degrees, and the oxygen will disappear.

You also asked. You should know too. If there is really no sun, it is deep enough for her. This bankruptcy is everybody, um a person knows, I think everybody should be aware of this kind of thing.

No, life needs light to survive.

It shouldn't be, not only plants need photosynthesis, but people also need to bask in the sun to replenish calcium and carry out daily lighting.

With the current conditions of scientific development, it is impossible to balance everyone!

Then artificial sun, if there is none, human beings can only be extinct.

Anything that people should eat needs the sun, and if there is no sun, people should not be able to last long.

If there is no sun, human beings will not survive, there is not such a saying"Everything grows on the sun"Without the sun, everything on the earth does not grow, can people still be clean?
