If the sun suddenly disappeared, how long would humans be able to survive on Earth?

If the sun suddenly disappears, we won't feel it until 8 minutes later. As the sun disappears, the temperature on the earth will get lower and lower, and after humans can survive for about a month at most, the earth will form an ice ball and freeze all the creatures on the earth to death.

We won't survive for a long time, because without the sun, plants can't photosynthesize, we don't have oxygen, and we will slowly disappear.

I have time to read my article "Controlled Nuclear Fusion"Artificial sun"Why won't it work? 》.Who is faster at the speed of light or the speed of sound? 》…Look"A jasper orchid chasing stars in Lingjing Lake"Can.

Is the Sun the boss of the Milky Way? Please be a little more serious when writing articles.

I feel like humans can survive on Earth for a year. Because plants need sunlight to produce photosynthesis, without sunlight there are no plants, there are no crops.

The sun suddenly disappeared, and humans had about a month to live.

Life on Earth depends on solar light and heat. The sun doesn't disappear, and if it suddenly disappears, what will happen after a catastrophe? How long can humans survive? The sun has suddenly disappeared, is there any way to solve the problems caused by the sudden disappearance of the sun? <>

First of all, know that if the sun disappears, the earth will be dark. It takes time for sunlight to hit the earth, it takes eight minutes. Gravitational waves move at the same speed as light, and if the sun suddenly disappears, after eight minutes, the Earth loses its sunlight and becomes dark.

At the same time, without the gravitational restraint of the sun, the earth may run out of the solar system because of the loss of the gravitational pull of the sun. What would happen on Earth if the sun suddenly disappeared? The earth is plunged into darkness, and this darkness is not night in the sense of the word.

Normally, at night, the sun is present and will be irradiated by the sun and use the moon. Now it is said that after the sun disappears, there will be no sunlight and the earth will fall into real darkness. <>

When plunged into darkness for an instant, humans have no effect, just like the usual night. In the dark, what happens next, the temperature of the earth continues to drop, and after a week, the average temperature of the earth may drop below zero, at which point, a large number of animals will die. Humans, with clothes, heaters, and other items that are warm, can theoretically survive for a period of time.

After a month, the Earth's temperature will drop to minus 50. At this time, humans can't bear it and may freeze to death, with the exceptions of course. If it lasts for half a year, the temperature drops to minus 100, and humans can't live indoors and can't survive in the wild.

Even if you barely survive, you will have to have food in the space where humans can live. Humanity continues to live for ten years, but one day it will run out, and if so, it will be difficult to live. For wind power plants, power stations that can operate, for nuclear power plants, radioactive fuels can run for decades, hundreds of years.

If the sun suddenly disappears, there should be huge ** and losses for human beings, but human beings will continue forever, because human technology can ensure the survival of a small number of human beings without the sun.

Humans don't live for more than 24 hours, because when the sun disappears, the top of the earth becomes very cold, and humans die because of extreme temperatures.

Then humanity on Earth will be completely extinct within a month, including other living things. So the sun is vital to humans.

What would humans do if suddenly the sun disappeared?

According to scientists, the sun will be completely extinguished on a distant day, about 5 billion years, and will no longer shine and heat, and this time may fluctuate up and down, but this is too far away, because the sun is the only star in the solar system, stars will shine and heat, but stars also have a lifespan, it cannot exist forever.

The impact of the disappearance of the sun in the short term is just that the temperature on the earth drops rapidly, all living things will become extinct, and the water will all become solid, as for what will become lower in temperature, we don't know, because most of the heat on the earth is the light emitted by the sun itself, after a long time in the universe to the earth, the earth itself is exposed to the radiation emitted by the sun's rays, and then there is a rise in temperature, under the thermal insulation of the earth's atmosphere, The temperature of the earth is kept within a constant range, which is suitable for the survival of animals and plants on the earth.

The long-term effects of the sun's disappearance are basically not felt by us, because the sun is the center of the entire solar system, and if it suddenly disappears, it means that the entire solar system has no orbit. All the eight planets revolve around the sun, and the sudden disappearance of the sun means that it has nothing to surround it, and the orbit will be chaotic, and if several satellites collide together, the impact will be devastating, because the sun is the core of the solar system, its own mass is the largest, and the gravitational force is also the largest, it firmly controls all the stars in the solar system, and the satellite sun disappears, which means that there is no bondage.

It is impossible for the sun to disappear suddenly, because the universe is so big, it must have its own laws, and if you want to be able to change the universe, that is not what we can imagine with the power we have now.

If the sun disappears, what will affect human beings?

Thanks for reading this**.

Without the sun, humans can live for about 1 year. The sun disappears suddenly, and the earth does not cool down immediately due to the warming effect of the atmosphere, but the temperature difference between the day disappears (the temperature at night is generally 10 degrees lower than during the day), and the temperature difference between the four seasons also disappears. The Earth's surface temperature drops to 0 during a month's drive and to 0 after half a year.

In the year it drops, and by this time, liquid water no longer exists.

There will be other changes to the Earth after the sun disappears:The entire solar system lost its gravitational pull, and the nine novae no longer moved around the sun. After 8 minutes, the Earth began to move in a straight line.

And the moon will still be a satellite of the earth because of the gravitational pull of the earth, but we can no longer see the moon because the moonlight is the reflection of the sun.
