What would happen to humanity if one day the sun suddenly disappeared?

If the sun suddenly disappears one day, the earth will not collapse immediately. We don't immediately notice that the sun is gone, in fact it takes 8 minutes and 20 seconds for light to travel from the sun to the earth. So we won't know until 8 minutes and 20 seconds later that we're in the dark.

The earth began to move in a straight line.

The entire solar system.

Losing its gravitational pull, the 9 novae no longer orbit the Sun and begin to go their separate ways. After 8 minutes, the Earth began to move in a straight line.

And the moon will be because of the gravitational pull of the earth.

It's still a satellite of the Earth, but we can't see the moon anymore because moonlight is a reflection of the sun. Although the Earth began to deviate from its original orbit, the collision between the planets is still a small probability event.

will not be the number one threat to humanity.

Photosynthesis. disappears, the Earth's ecosystem.

First, most of the plants lose sunlight, photosynthesis stops, and gradually die, followed by herbivores that begin to gather and leave, and then carnivores.

Of course, humanity will definitely be the last to become extinct.

At the same time, the gradual death of the plant will cause the oxygen to gradually start to decrease, although this rate will be very slow and will not affect it in the short term.

Marine life can carry it a little longer, but all oceans will freeze over 1,000 meters thick, and the creatures that live on the bottom of the ocean will gradually become extinct. Only microorganisms that live on the ocean floor, relying on geothermal heat to survive, may survive. Then the entire planet, except for the depths of the oceans, will be frozen.

The Earth begins to cool down and the sun suddenly disappears due to the atmosphere.

The earth does not cool down immediately, 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 in a month and to half a year later. In the year it drops, and by this time, liquid water no longer exists.

We expect that it can support it for about 1 year.

In the initial stage, natural resources, especially marine resources, science and technology, can be used to make a living. At this time, the biggest problem is within humanity, because the panic caused by the disappearance of the sun can cause turmoil and various crises. And the disappearance of the sun caused by the ** and tsunami, etc., let the thermal power station.

Nuclear power plants became ideal settlements.

The ocean becomes the focus of resources, and the seabed is fossil energy.

And uranium mining technology continues to improve, replacing geothermal energy, and all human research resources are moving towards controlled nuclear fusion.

Incline. Humans will speed up the development and exploitation of energy, perhaps find some food alternatives, and hope to develop alternatives that do not rely on photosynthesis, and marine plants will become a hot spot. The key is the continuous drop in temperature, when it drops to about -100, the oxygen begins to liquefy, and at this time humans cannot hold on.

Therefore, the disappearance of the sun will damage our ecological balance, and plants will not be able to photosynthesize, causing plants to wither, and we can only rely on the creatures in the sea to provide energy for ourselves.

What would happen to the Earth if the sun suddenly disappeared? What will happen to humans?

The Earth will enter an ice age, and humanity will not be able to bear the cold and will gradually disappear, as will other living things.

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?

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 in a month and to half a year later.

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 stopped moving around the sun and began to go their separate ways. After 8 minutes, the Earth began to move in a straight line.

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 a reflection of the sun.
