What will happen to the earth if the sun goes out. What will happen to the earth if the sun disappears. What is the sun

The sun will die one day, but it will be in a hell of a lot of years. And even if we remain on this planet (which is unlikely), we will also be demolished by the force that destroyed our luminary in an instant. All houses, monuments, buildings, art and nature reserves will disappear. Therefore, it is pointless to try to describe in stages the real attenuation of a star, because we will no longer exist, and all forecasts are just theories, which, however, are as close to reality as possible. So let's fantasize. Imagine that the sun somehow magically disappeared. Just like that, in one moment, without any destruction, as if it was simply turned off, as you do with your desk lamp. What will happen to the planet? BroDude has collected reliable information based on scientific sources and shares it with you.

1. Darkness

The only source of light will be the stars. The moon will disappear from the sky, although we can observe such a dark round spot if we go out into an open field with clear sky. We will not notice the temperature difference so quickly, because your tea does not cool quickly either.

2. Temperature

It will gradually level off under the general indicator. The poles will have the same degree as the equator. It will take the Earth about 10 days to approach zero, and in 20 days the ice will spread over the entire water surface of the planet. We may be able to warm the planet artificially, but with current technology, this measure will be short-lived. Temperatures will reach minus 40 degrees Celsius by the end of the year, but even so, the oceans won't freeze completely for hundreds of thousands of years.

Within millions of years after that, the Earth will reach a stable temperature of minus 160°C, at which the heat emanating from the core of the planet will be equal to the heat that it radiates into space.

Caltech Professor of Planetary Sciences David Stevenson

3. Life

A person adapts to extreme conditions very quickly, so some centers of civilization will certainly be able to exist for a long time. For example, geothermal springs, volcanic heat that did not depend on the sun, can serve as an excellent way out. Take, for example, Iceland, where already now about 87 percent of the houses are heated by such energy. But most of the people will die, and those that remain will turn back the whole scientific progress, returning to primitive forms of labor organization and relationships. Most other living organisms will also die, they will settle dead bodies over the entire surface of the planet, recalling that once there was full life. Photosynthesis will stop, most plants will die in the first weeks, but large trees, thanks to their metabolism, will be able to live for several more decades.

4. Breakaway

The earth is no longer held on a gravitational leash, . Therefore, most likely, she, along with the moon, will go to space trip, eventually flying out of the solar system. It will be sad if the moon leaves it. There will be such an eternal trip alone through the vast expanses of space.

5. Addition

– The risk will decrease solar flares. The threat of solar flares and magnetic storms very vital. In 1859, one of these flares that hit the Earth turned off the telegraph equipment almost all over the planet. No sun, no solar flares.

– Satellite communications will improve. From solar energy The radio signal is weakening, causing outages in the satellite. Enough tolerating this!

– Astronomy will develop. It is logical here: observatories could work around the clock with all the ensuing consequences.

– Trading will become easier. Time zones stress people out. It is difficult to interact with the person whose working day is different from yours. When the sun is gone, the need for them will disappear. World economy will be strengthened when there is universal time.

– Hogweed will become safer. This insidious plant contains poison, which, if it gets on the skin, can cause serious chemical burns. But this poison is activated only when sunlight hits the affected area. Therefore, there is no sun - there are no chemical burns from hogweed.

The sun is the center solar system, and if it suddenly disappears, cold and darkness are far from the most serious problems that humanity will have to face.

After 8 minutes after the disappearance of the Sun, all the planets of the solar system will stop rotating in their orbits (no Sun - no gravitational attraction) and will begin to move in a straight line through space until they fall into the gravitational field of another massive body.

After 10 minutes The earth will be plunged into darkness. The fact is that it takes nine minutes for sunlight to reach our planet. Accordingly, in nine minutes we will receive the last portion of the light that was already on its way at the time of the disappearance of the Sun. At the same time, humanity will stop seeing the Moon, because now it is visible due to the fact that the Sun is reflected from it. At the same time, the ability to see the stars will remain, because they are sources of light for themselves.

In a few days the extinction of microorganisms will begin, most of the bacteria will die. Without the sun, only microorganisms living in earth's crust, because they will be heated by the core of the planet.

In a month humanity's only chance for survival will be life in submarines, in the deepest and warmest parts of the ocean, or in a completely isolated habitat on land.

In a few weeks photosynthesis will stop, but there will be enough oxygen for a while. All animals will die with the exception of scavengers, who will live longer by feeding on dead individuals.

After two months the temperature on Earth will drop to -123˚С and the surface of the oceans will freeze. Only species living in the deep layers of the ocean will survive. At the same time, the main body of water will remain in liquid form for millennia, since it will be protected by an ice cover.

A few decades later only large trees will remain on the planet that are able to exist for some time without photosynthesis.

The mass of the Sun is about 333,000 times that of our planet and produces the same amount of energy as 100 billion hydrogen bombs every second. The giant mass makes this star the dominant force of gravity in the entire solar system, firmly fixing all eight planets in their orbits. At the same time, the energy of the sun heats the Earth to the extent necessary for the presence of the catalyst of life - water.

gravity

Before Einstein asked the question, scientists believed that gravity changed instantly. If this were indeed the case, then the disappearance of the sun would instantly send all eight planets on an endless journey through the dark depths of the galaxy. But Einstein proved that the speed of light and the speed of gravity propagate at the same time - which means we will have another eight minutes to enjoy ordinary life before we realize the disappearance of the Sun.

Eternal night

The sun may simply go out. In this case, humanity will not remain in complete darkness, on a planet filled with desperate madmen. The stars will still shine, the factories will still work, and people, quite possibly, will not start lighting the fires of the Inquisition for another ten years. But photosynthesis will stop. Most plants will die within a few days - but that's not what should worry us the most. average temperature The earth will fall down to -17 degrees Celsius in a week. By the end of the first year, our planet will begin to experience a new glacial period.

remnants of life

Of course, most of the life on Earth will cease to exist. In less than a month, almost all plants will die. Large trees will be able to hold out for several more years, as they have large reserves of nutritious sucrose. But, nothing will threaten some microorganisms - so, formally, life on Earth will be preserved.

human survival

But what will happen to our species? Astronomy professor Eric Blackman is confident that we can easily survive without. This will happen thanks to volcanic heat, which can be used both for heating homes and for industrial purposes. It will be best to live in Iceland: people here are already heating their houses with geothermal energy.

Endless journey

But worst of all, the absence of the Sun will rip our planet off its leash and send it on a long, long journey. The planet will rush in search of adventure - and, most likely, will find them with ease. Unfortunately, this will not end well for us: the slightest collision with another object will cause huge destruction. But there is a more positive scenario: if the planet is taken aside Milky Way, then the Earth may well find itself new star and enter a new orbit. In such an incredibly unlikely event, the people who have flown will become the first astronauts to overcome such a significant distance.

At the same time, the energy of the sun heats the earth to the extent necessary for the catalyst of life to appear - water.

But what will happen if the sun suddenly takes and disappears? Many people cannot even imagine such a situation. However, the problem posed is not as stupid as it seems at first glance. At least, Albert Einstein himself did not neglect this thought experiment - well, we, based on his calculations, will try to tell you what will actually happen to the earth if a star suddenly goes out.

I heard that time erases everything...
BG "Adelaide"

In fact - in my opinion, the main question of philosophy, for thinking people, should be this: "What will happen if the Sun explodes?" or more precisely, even "When the Sun explodes"? And not at all in well-known questions: "What is the meaning of life" or, for example, "What is primary - matter or consciousness." This question is of course deeper and more serious from a philosophical point of view, although the answer to it is short and obvious - “Our whole world will evaporate without a trace, and everything”, without any trace at all, nothing will remain at all, everything here will simply evaporate in the vent of plasma thermo nuclear reactions and again everything will become the simplest atoms - the structure will crumble into separate smallest elements, and any information will simply disappear - forever and irrevocably. This is certainly an impressive sight when everything disappears, absolutely everything - without any hope of restoration. The whole and the world - everything you can touch and remember - everything will disappear - as And absolute silence and calmness will come again, on all waves. As there was a drawing, they brushed it off and there is nothing - and it is impossible to collect the main thing back. And we will not notice this suddenness - when the drawing is suddenly swept away.

But on the other hand, suddenly and during our lifetime, this event will certainly not happen, well, unless some unexpected catastrophic solar reaction happens, something goes wrong on the Sun - just like the sea and the river, too, because they are also stable substances, or mountains , but sometimes it will spill or some kind of tsunami will arise, or an earthquake or some kind of collapse where no one expected - and everything is calm for a hundred thousand years. And it will destroy half of the coast, or, for example, country houses that were at the mouth of the river.

But there is also a feeling - if the Sun suddenly explodes - we will not even notice this at all - we will evaporate in a split second and that's it. (Of course, it is understandable that the heat wave will go on for about eight eight minutes - not faster speed Sveta. But if such a volumetric explosion in different sides with instantaneous expansion - we will not notice anyway. There were right away - no, here you sit, for example, write on a computer, drink coffee, and someone reads. Since there is nothing at all - this is the depth of meaning.)

Reminds me of an old joke about this:

The lecture is on astronomy on the topic "Life Cycles of the Sun", which means the professor explains: "And after about five billion years thermonuclear reactions will gradually stop and the sun will go out. And from the back rows the question: “In how much, in how much?” The professor repeats: "In five billion years." And there: “Well, huh, otherwise I heard that in three billion” ...

Approximately these are the arguments about what will happen when the Sun goes out - very exciting in terms of their scale, but still purely empirical events for us. And in any case, too

But the Sun is not the most big star- so among the many, many stars of ours, not just the Universe, but the Galaxy, which is also just one of - as scientists from 200 billion other galaxies suspect.

And judging by how these stars are born, develop and then die, astronomers can judge the periods of life and our Sun.

And in fact, everything will develop as follows: after about 1.1 billion years, the Sun will already be brighter by about 11% (according to Wikipedia) - and at this time, the disappearance of life on planet Earth is approximately and possibly. In another 3.5 billion years, the brightness of the Sun will increase by another 40% and all life will disappear on Earth. (With the entire life cycle of the Sun, respectively, you can get acquainted -.)

And the Sun is actually not a yellowish color as we used to imagine - but it looks like this.

And of course, everything in this world will end and disappear for each individual person. And it's not that the Sun will disappear for everyone, but the entire personal Universe will suddenly cease to exist, and everyone will eventually gain absolute Freedom - in general from everything material. Forever and ever.

We are all so accustomed to the Sun that we cannot even imagine that it will suddenly disappear. Accordingly, we have no idea what will happen to the Earth if the main planet of the solar system suddenly disappears. However, a similar question was once asked by Albert Einstein. Based on the writings of this great scientist, as well as modern knowledge, we will tell you what will actually happen if the Sun disappears.

According to the calculations of modern astronomers, the Sun will exist in its current form for another 5 billion years. Without it, life on Earth cannot exist for a long time, and even more so, it cannot be born.

The sun went out

If you turn on your imagination and arm yourself with some knowledge, you can imagine what will happen when the Sun goes out. Solar energy is the root cause of life on Earth. It starts many processes that take place on our planet, vital for all organisms. Immediately after the cessation of the energy of the Sun on the Earth's surface, it will begin to freeze gradually. Within 45 days, the planet will be completely covered with a thick layer of ice. The first will be the land, especially the regions far from the sources of water. The seas and oceans will be the last refuge of solar energy on the freezing Earth, because most of it is absorbed by the hydrosphere. The temperature in the ocean even at a depth of 35 meters is about 15 degrees. Plants will die in a few days. The disaster will encourage people to look for alternative sources of heat. One of them is the greenhouse effect. Infrared radiation coming from the surface of the planet will be delayed by clouds for some time, preventing it from cooling down. But the clouds will disappear through a short time, since the water will no longer evaporate due to the lack of solar energy. Perhaps people will start burning the forest so that the greenhouse effect occurs due to the high concentration of carbon dioxide in the atmosphere. Minerals and nuclear fuel can also serve as energy sources. But humanity will lose the main element necessary to sustain life - oxygen, which was produced by plants. We will have to create an artificial environment for their cultivation. Salvation for some people will be possible if they fly into space. However modern technologies won't let them stay there for very long. In space they will find their final resting place.

Sun evolution

All of the above is just a model, possible if the Sun actually goes out. This is possible only in 5 billion years, when all hydrogen disappears - the main source of thermonuclear energy, due to which all processes take place inside and on the surface of the star. Before that happens, the Sun will give the inhabitants of the Earth an unpleasant surprise. The final chord of his life as a source of heat will be the transformation into a red giant. Its temperature will rise several times, which will have a detrimental effect on the Earth: the oceans will begin to boil, the land will turn into a scorched wasteland. The star will then turn into a white dwarf.

What will happen to the Earth if the Sun one day "fails"? Scientists have again asked this question. At first, no one will notice that the Sun has stopped shining, they say. This will become clear only after eight minutes - that is how long it takes for light to travel from a star to the Earth. After this time, night will fall on our planet, foreign media report.

Comets, solar explosion, supervolcano

How will our planet die?

After a few more hours, the temperature will begin to drop. According to Professor David Stevenson of the California Institute of Technology, in a few days the surface of the Earth will already be covered with ice, and in a week the temperature will drop below zero degrees Celsius. In a year it will get colder to minus 100 degrees Celsius.

In such extreme conditions, only some microorganisms will be able to survive, while most of the wildlife will disappear. The plant world will die first.

However, people will be able to escape if they hide in the depths of the ocean, experts say.

However, the luminary not only warms our planet, but also keeps it in orbit. If it goes out, the Earth will be outside the solar system and may collide with another celestial body.

What will be the solar apocalypse

And how long to wait

It is worth noting that geomagnetic storms on Earth are associated with solar activity. They occur quite often, people have adapted to them. Nevertheless, technological development gives rise to new risks with strong perturbed solar wind streams that are directed towards our planet.

Magnetic storms great strength is a rather rare occurrence. It can be seen once every few centuries. Predicting space storms is almost impossible.

The strongest solar flare was observed in September 2017. She was assigned an activity class X. What happened was the logical outcome of a week-long series of solar flares and geomagnetic storms on Earth. These days, many people have complained about their well-being.

What happens if the sun explodes. If the sun explodes...

The very idea of the possibility of the death of the sun is not new. A hundred years ago, the first assumptions appeared that someday it would go out and darkness and cold would fall on Earth. Fantastic thrillers and stories were created on this topic. However, scientists quickly reassured the population of the planet, explaining that the sun will burn for at least another billion years. There was another version - that the sun will explode and all the planets, including the Earth, will simply burn in a cloud of hot gas. And again, scientists took up the pacification of excessively hot minds - and created a theory according to which the sun should not explode at all, since stars of this type peacefully burn out and turn into white dwarfs.

For several decades, everyone lived in relative calm - apart from a meteorite strike from space, they did not expect any danger. From time to time, someone frightened peaceful earthlings with black holes, wandering stars and poisonous gas nebulae, but all these hypothetical threats were too far away and were not taken seriously.

And now a new threat has appeared - overheating and an explosion of the sun. From the point of view of classical astrophysics, this is impossible, since there are equations according to which stars must “work” with a constant temperature. But we have already seen more than once that nature stubbornly refuses to follow the postulates of physics and generally behaves undisciplined. This time, the temperature of the core of our luminary has unreasonably increased - according to media reports - several times. The interesting thing is that in principle this is possible - this means that the rate of nuclear reactions has increased dramatically inside the sun. There may be several reasons, and one of them has long been described in the stories of the famous Soviet science fiction writer A. Kazantsev - the sun could "swallow" some matter that became a catalyst. If this continues, if the sun does not want to shine "according to the rules", then the greatest catastrophe awaits us.

The whole horror is that the instantaneous combustion of the planet described by science fiction writers will not happen. The promised explosion most likely will not happen, since the forces of gravity will keep our star from expanding instantly. First of all, a simple increase in the temperature of the core of the sun will lead to an increase in the emission of heat and light, as well as radiation. This means that on Earth during the day it will simply be impossible to go outside - on the sunny side, the temperature can reach 50 degrees and above! The amplification of light and other types of radiation will lead to damage to the skin and vision. Melting ice is inevitable - but this is not the worst thing. Rising temperatures will lead to terrible hurricanes. The wind speed will reach 300 km/h and higher, all light buildings and trees will simply be swept away from the face of the planet. At first, cold hurricanes with snow will be replaced by warm ones, bringing showers and thunderstorms. It will simply destroy all tropical vegetation and doom hundreds of millions of people to starvation.

Only those who will live in strong stone or underground buildings away from the coast and stock up on food will be able to escape. As long as the ice melts, the hurricanes will not stop - but at the same time, the temperature will remain within the limits of human survival. Unless in the countries of the tropical zone it can become such that a person will simply have to hide in caves or burrow into the ground - so as not to literally burn out.

An increase in temperature will lead to an increase in the evaporation of water. And soon thick clouds will close the planet, which will reduce the flow of solar energy. thermal radiation, but at the same time saturated with steam the air will be very difficult to breathe. Many people with weak lungs and hearts will not survive in such a "bath". However, part of the population - especially those who have material or power resources - will be able to live in underground buildings, where, as you know, the required air temperature can be maintained without much difficulty. How long will depend on food and water supplies. Meanwhile, on the surface, the temperature will rise until the balance between the energy received from the sun and its consumption is balanced. Whether it will be +50 degrees Celsius, or +60, or maybe all +80 - this is unknown. But in any case, under such natural conditions, the vast majority of living beings will die. Single-celled, some sea dwellers, primitive plants will survive.

By the way, about 500 million years ago natural conditions on Earth were very hot. And it is possible that then the reason for this was also increased activity sun. Can everything happen again? This is not out of the question.

But what if there is an explosion? Then, before our planet is covered by a wave of hot gas, the first to come to us is sunlight. Thousand times stronger than usual. Everything that is not in the shade will instantly flare up, the temperature will rise on the sunny side of the planet. But ash and evaporating water will rise into the air and cover the sky - and sunlight, no matter how strong, will only partially penetrate them. It will turn out a terrible steam oven, in which those who are unlucky enough to burn out in the sun in the first minutes will die the most painful death. The first streams of solar gas will reach the Earth only after a few hours.

It is impossible to turn off the Sun at the snap of a finger. It also can't just disappear. Nevertheless, scientists know exactly what will happen to the Earth and its inhabitants if the Sun goes out.

We at Bright Side decided to tell you about the main events that will follow. And at the end you will find the answer to the question of what really awaits the Sun and our planet in billions of years.

8 minutes 20 seconds

Cosmonauts of the International space station will understand that something is wrong with the Sun, in the first place. But even they will not know about it until 8 minutes 20 seconds later. This is how much light travels from the Sun to the Earth.

After the sun goes out, the entire planet will be at night. And people won't be able to see the moon. The thing is that by itself the satellite of the Earth does not produce light. It only reflects the sun's rays. This means that without them we will not see the Moon, as well as other space objects visible due to reflected light.

planet temperature

After that, the Earth begins to cool rapidly, as is usually the case with a hemisphere where night reigns.

It is estimated that in a week the average surface temperature of the planet will drop below -20 °C. For a year - somewhere up to -73 ° С. In the end, the temperature will drop to -240 ° C and will remain at this level.

Life in the Earth

Plants will be hit first. They cannot exist without photosynthesis, which, in turn, is impossible without sunlight. All small plants will die within a few weeks. But large trees can last longer - several years. This is possible due to the large supply of glucose that plants produce during photosynthesis and the slow metabolism.

The food chain will be broken, which will lead to the rapid extinction of wild animals. The last to die are the scavengers.

People can escape by hiding in the depths of the oceans or underground, where the heat will last the longest. After all, the core of the Earth will still be hot. Perhaps humanity will even learn to grow plants and animals in such conditions. Energy could be obtained from nuclear reactors and geothermal sources.

But even if humanity fails to survive, individual microorganisms will continue to exist even in the most adverse conditions. Therefore, formally, life on Earth will be preserved.

Video IF THE SUN GOES OFF FOR 24 HOURS

According to recent data, the Sun, with the help of emitted light, causes the Earth to gradually approach it. This phenomenon is called the Poynting-Robertson effect, it is related to all celestial bodies in the solar system. Moreover, it has been proven that the smaller the size of a celestial body, the faster it will “fall” onto the surface of the sun.

Scientists have determined that all the objects of the Solar System that revolve around the central luminary should eventually approach it - after all celestial bodies moving in a spiral path. Experts believe that small objects such as stones, dust particles will fall to the surface much faster.

The mechanism of this phenomenon is based on the changing momentum of the particles. It is known that it directly depends on the mass or energy of the body. When a body absorbs solar energy, its mass increases, but at the same time the momentum remains unchanged, as a result, we get a decrease in the speed of the body.

Since the speed of movement of a particle or a body decreases, the gravitational force of the Sun begins to influence them much more strongly, due to which the orbit of the movement of celestial objects gradually begins to decline. If you believe this theory, then absolutely all the celestial bodies of the solar system will approach the Sun and be absorbed by it.

In other words, scientists are predicting the next end of the world for the planet Earth and humanity, the date of which is still unknown.

What happens if the sun goes out.

What does the sun mean to us? It warms us with its warmth, gives us light and energy. Without the sun, we would never know what a day is, it would simply not exist. And if for a moment imagine that the sun suddenly goes out? What will happen then? We are so accustomed to knowing that the sun always shines that it is very difficult for us to imagine that one day this may not be. However, this idea is not as fantastic as it might seem.

If one day it so happens that the sun really ceases to shine, then eternal night will come, moreover, without moonlight, as the moon does not shine by itself, but only reflects the sunlight. Then winter will come, also eternal, and on the whole planet the earth at once. Temperatures will drop to around minus 150 degrees Celsius and stay that way forever.

Life in such conditions is practically not real. Solar energy is central to the origin and maintenance of life on earth. It starts many processes occurring on our planet, vital for all living organisms. Without it, life on earth cannot exist for a long time, and even more so, it cannot be born. Therefore, immediately after the cessation of the energy of the sun on the surface of the earth, it (the earth) will begin to freeze gradually. According to scientists, within 45 days the planet will be completely covered with a thick layer of ice.

The land will freeze first, especially areas far from water sources - for example, deserts. The plants will die within a few days. The seas and oceans will be the last refuge of solar energy on the freezing earth. The temperature in the ocean, even at a depth of 35 meters, is about +15 degrees. As a result of the onset of a sharp cold, all bodies with a temperature above zero will rapidly cool down, including people.

About a month after the sun goes out, atmospheric gases crystallize. They will become hard. It will look like precipitation, something like frost. That is, it will become impossible to breathe oxygen (if there is still someone to breathe). In addition, many people will begin to die from hypothermia, especially in those countries and continents where there is never winter.

Such a catastrophe will undoubtedly force people to look for other sources of heat in order to survive. One of these sources may be clouds, which will not allow the earth to cool for some time. But the clouds will also disappear after a short time, because the water will no longer evaporate due to the lack of heat. Perhaps people will start burning the forest to heat the air and thereby cause moisture to evaporate. Minerals and nuclear fuel can also serve as energy sources.

But the main problem is that humanity will lose the main element necessary to sustain life - oxygen, which was produced by plants. We will have to create an artificial environment for their cultivation. For a certain number of people, salvation will be possible if they fly into space. However, modern technology will not allow them to stay there for very long, and space will become their last refuge.

In general, from the foregoing, we can conclude that if the sun goes out, life on our planet will stop very quickly. But still, you should not panic. According to the calculations of modern astronomers, the sun will shine to the delight of people for about 5 billion more years, and this, as you yourself understand, is a very, very long period of time.
