What happens if the sun goes out. What happens if the sun goes out instantly? What will happen if the Sun goes out: an apocalypse or a new life? What will happen to the earth if the sun goes out

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.

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.

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 that we will enjoy ordinary life for another eight minutes 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. The average temperature of the Earth will fall to -17 degrees Celsius in a week. By the end of the first year, our planet will begin to experience a new ice age.

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 unleash our planet 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 carried towards the Milky Way, then the Earth may well find a new star for itself 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.

Today we will talk about such a dark topic: what will happen to our planet if there is no Sun .. And will there be anything at all.

In order to understand what can happen with the death or elimination of the Sun as the main luminary on the planet, you must first evaluate the role of the Sun during its lifetime. Of course, this information cannot be contained in one article, people have been studying the brightest star for thousands of years and it still remains a part of the mystery for them, but let's try to briefly reflect the essence.

If the Sun goes out, the Earth will die in just 8 minutes 20 seconds

Sun

The sun is the most powerful natural nuclear reactor! The temperature inside the Sun is over 16 million degrees Celsius, outside it is over 5 thousand, the temperature is gradually rising.

The sun is now about 4.5 billion years old, which is at least half of its life, that is, it still lives in an ideal scenario no less than what it already has.

No wonder even the Earth is one of the planets of the solar system. The Sun "controls" everything in our Universe, satellites, planets, asteroids, meteorites revolve around the brightest and main star. The sun, depending on the distance and approach of the Earth, heats our planet, and winter or summer, autumn, spring begins on it, and when the Earth turns around its axis with the back side, we have night, then day. In summer, there is a short night cycle, since the Earth is close to the Sun at that moment, so it illuminates the planet better than in the winter season.

Few of us even imagine the situation that the Sun will not warm forever and may go out one day. This is perhaps the last thing a person thinks about, walking on the mortal earth, being filled with thoughts.

But in vain ... The sun is not really eternal.

So, we will consider the scientific versions later, but for now, what will happen if the sun goes out according to naive earthlings.

- It will immediately become cold, dark and all living things will die, perhaps within a few seconds, and possibly days.

- On the first day, everything will be familiar, but so the word night has come, on the 9th day the temperature on the whole Earth will become the same minus, on the 20th day water bodies will freeze, in two months the temperature will drop below 60 degrees Celsius, in 6 years the Earth will be in the orbit of Pluto, in 10 years the temperature will be minus 150 degrees.

“For the first few minutes, we won’t even understand that the Sun has gone out, then a state similar to night will come, the Earth will gradually begin to cool down, after which the temperature will reach minus.

“Before it goes out, the Sun will increase and swallow the Earth, but if we imagine that it simply “turns off”, then the Earth will become dark, cold on the outside, but inside it will still be full of red-hot lava.

“Gravity, by which we “fly” around the Sun, will disappear, and we will fly through the window at a speed of more than 1000 km per hour into the distant unknown, and our planet, which has descended from orbit, will collide with some kind of meteorite.

- A small part of people on the whole Earth will survive - a few thousand, they will settle in a bunker, will produce energy using autonomous nuclear power plants, but in 30 years all uranium and plutonium reserves will run out and all people will die.

But most importantly, the versions of why the Sun can lie abruptly go out:

- His life cycle will end, the length of which none of the mortals knows, will end abruptly and unexpectedly,

- The sun will incinerate itself, that is, the thermonuclear reaction on its surface will reach maximum values, after which it will explode, -

- Man, with his detrimental actions in relation to nature, to the atmosphere, will somehow affect the life of the Sun and it will go out before it malfunctions.

What is the result and conclusion can be drawn from the report? According to people, the "death" of the Sun can come unexpectedly, for no reason, all that humanity expects after the exodus of the Sun is death.

And now let's talk from a scientific, a little philosophical and religious point of view.

Where did the Sun come from? God created it:

“1 In the beginning God created the heavens and the earth.

2 And the earth was without form and void, and darkness was over the face of the deep, and the Spirit of God hovered over the waters.

3 And God said, Let there be light. And there was light.

4 And God saw the light that it was good, and God separated the light from the darkness.

5 And God called the light day, and the darkness night. And there was evening and there was morning: one day.

13 And there was evening and there was morning, the third day.

14 And God said, Let there be lights in the firmament of heaven [to lighten the earth, and] to separate the day from the night, and for signs, and times, and days, and years;

15 And let them be lamps in the firmament of heaven, to give light to the earth. And it became so.

16 And God made two great lights: the greater light to rule the day, and the lesser light to rule the night, and the stars; ("Being")

Another option:

“The solar system originated from one large cloud of gas and dust. This cloud began to shrink under the influence of gravity, as a result, the main part of the matter contained in it gathered into a central clot, from which the SUN subsequently arose. However, since this cloud was not initially stationary, but rotated slightly, not all of the mass of the cloud turned out to be concentrated in the central bunch.

It is even possible that both of these options are not mutually exclusive.

Why can the Sun go out from a scientific point of view?

In fact, no matter how we drink today the surprise and danger of an explosion on the brightest star, about the reality of its abrupt disappearance - do not believe it! Even according to the most modest calculations, the Sun will live for another 1 to 4.5 billion years. But we don’t know, of course, what awaits us tomorrow, and if we proceed from the fact that the world was created (by God, by chance or otherwise), then we can also come to the conclusion that the world can disappear just as unexpectedly as it appeared, in including the sun. In connection with this hypothetical possibility, a number of scientists predicted what would happen to the planet after the death of the Sun, in particular Einstein, specialists from NASA, Harvard, etc.

We were predicted the end of the world in the form of a “shutdown” of the Sun in 2012, and before that several times, but the planet is alive. We are told about flares on the Sun, about its anomalous activity, about the greenhouse effect, about the harmfulness of the now incandescent shell and radiation. However, according to peaceful forecasts, half of her life is still before the death of a star.

Scientists have found that stars of similar type and mass, like the Sun, live for about 10 billion years, and it lives for half, gradually it consumes its hydrogen fuel, and the temperature will rise, in a billion years it will enter the stage of a red giant, not earlier than in 3 billion years the sun will shine twice as bright, the water will evaporate, all forms of life on earth will be impossible. By the period of 10 billion years from the birth of the Sun, it will enter a period of dying, the process of burning the shell will begin, the Earth will be absorbed by the Sun, or it will be dried up and deprived of an atmosphere.

Here, for example, is a brief description of the "death" of the Sun, according to observations of the death of another star after its transformation into a bego dwarf:

“American researchers from the Harvard-Smithsonian Center for Astrophysics, as a result of observing the behavior of the star WD 1145 + 017, simultaneously recorded a white dwarf, the remnants of another planet and space debris within the same system, reports Sci-News.

Andrew Vanderburg, astrophysicist, head of the research team: "We caught a white dwarf at the moment when it destroys its planet and scatters the remains on the surface of the star."

The scientist explained that once a star turns into a red giant, it destabilizes the orbits of the planets around it and absorbs them. This moment was captured by the NASA telescope. According to Vanderburgh, the same fate awaits the Earth. According to scientists, the Sun will swallow our planet in about 5-7 billion years..

But the transformation into a white dwarf will not be momentary, as you understand, this is again a long period, multimillion, multibillion is possible, and even becoming a white dwarf, the star will be able to emit light, but heat is unlikely ... Like a car without fuel, by inertia it will roll, but will no longer show strength and former activity. Now the star is 30% brighter than at birth, and it increases the brightness, volume. In a few million years, the temperature of the Earth will rise by 40 degrees, water from the oceans will begin to evaporate, the entire population will have to hide during the day in shelters, bunkers, and only come to the surface at night.

Even if suddenly, for unknown mystical reasons, the Sun suddenly goes out, then, as Einstein established during his research, people will not notice anything special for another 8 minutes, after which either inevitable death will come, or - “Then irreversible consequences will begin, the impossibility of photosynthesis, all plants will die, energy sources will dry out. However, in addition to those who say that after the death of the sun, our planet will face the same fate, there are those who claim that it will be possible to heat homes with volcanic ash and life will be possible, only the warmest weather on Earth will be minus 17 degrees Celsius, they will disappear trees, etc.”

It will be possible to live in bunkers, switch to an autonomous mode of maintenance and support of life, it is quite possible to exist for several decades according to the model of scientists. If during this time a person does not learn how to develop resources from the remaining opportunities, then he is threatened with imminent death, but he is threatened with death in any case, people will not last long on the cold and dark Earth. It will not be lucky for new people to be born at this time, they will literally not see the white light ... The only way to somehow survive is to use uranium and plutonium reserves to create and operate nuclear power plants.

Another option for the “death” of the Sun is not its death in the literal sense, but the exit of the planet from under the habitable zone of the star. The earth is at an optimal distance from the luminary, if closer - the temperature will rise, moisture will dry out, further - everything will freeze. So today the Earth is actively leaving this zone - according to the conclusions of scientists. When a planet leaves the habitable zone of the Sun, it will lose the resources necessary for life, according to the forecasts of astrophysicists - the Earth began to leave this zone much faster than predicted, and we have only some 1.75 billion years left to live under the light of a star. More precisely, not to us, but to our planet.

According to any, even the most dangerous forecasts, the Sun will live for at least another billion, of course, if nothing supernatural happens, as we mentioned. Therefore, you should not be very afraid that our star will go out.

Based on the available research, it is impossible to establish with accuracy what will happen to the Earth if the Sun goes out and whether the Sun can go out unexpectedly. There are only assumptions described in the article, including those of great scientists. However, it is clear that even if the death of the Sun does not lead to the immediate death of all life on the planet, it will lead to the gradual death of all life. The sun means too much to us, despite the fact that we do not notice it. Life on Earth, even without research, it is clear, will be impossible in a full-fledged format without the brightest star.

But questions still remain, especially after delving into the religious essence of the creation of the Sun. In the article above, I cited quotes from the Bible about the creation of the luminaries, the planet .... The question arises - if light was created before the luminaries, the Moon and the Sun, if man was created before the Moon and the Sun, like water bodies and all living things - maybe life on Earth is then possible without the Sun? And LIGHT OF DAY is possible without the light of a star?

Where did the light come from, if not from the Sun? In general, everything is difficult ...

However, as Christians say, for the mere fact that the Sun has risen above us today, we need to thank the higher powers. After all, it does not belong to us at all, and warms both the evil and the good.

We are used to living under the Sun and take it for granted, and few people think about the fact that much on this Earth is not in our power, including the Sun.

It is also amazing: the Sun, if it lives 4.5 billion years, and people a maximum of 80-100, then it’s funny how famously they make predictions about the life of celestial bodies, planets .... How do they know what will happen tomorrow and in how many billions of years the Sun will die??

And in general: scientists are discussing the topic of the Sun, looking for ways out of the negative radiation, all somehow from an economically, pragmatically advantageous position. But the Sun is such a romance, you can say - one look at it sometimes makes you remember eternity ... It's not for nothing that so many songs are dedicated to it, it's not for nothing that it worries us all.

The glow of the sun is caused by the intense combustion of various substances, primarily hydrogen and helium. The combustion temperature is so high that the reaction proceeds like a thermonuclear one, due to which the sun ...

Why does the sun have to go out?

The sun is a very small star, there are luminaries thousands and tens of thousands times larger. Initially, all stars shine thanks to the thermonuclear reaction of hydrogen nuclei, which at the same time turns into heavier substances: helium, oxygen, iron and even gold.

Under the influence of high temperature and pressure, these substances also begin to participate in the emission of light by the sun. Due to their high atomic mass and high amount of energy, the sun begins to cool as it grows in size. But at a certain stage, when there are too few light chemical elements, the temperature becomes insufficient for a thermonuclear reaction of heavier substances.

After that, the development of the star can go according to two scenarios. The heaviest stars, due to the high density of matter, the lack of buoyant forces from the extinct core, begin to shrink, turning into a black hole in a short time - an unusually dense area of space.

Since the size of the sun is more than modest, its extinction will follow a different scenario. In 2 billion years, it will noticeably increase in size, swallowing Venus. Then, having reached the orbit of the Earth, and possibly also having swallowed our planet, the sun will begin to burn the remnants of matter. When even iron burns out, the giant ball will explode, completely losing its upper shell.

In place of the sun, only a dense and gradually cooling core will remain., consisting of very heavy metals - a white dwarf. Based on astronomical data and a large number of examples, this should happen in 4-5 billion years.

What happens if the sun explodes?

The fading of the sun will not be gradual - our luminary will spend his last days very violently and actively. According to a pessimistic forecast, the Earth will not catch the extinction of the sun at all - being absorbed by the star's chromosphere, our planet will turn into a high-energy plasma. If the surface of the sun does not reach the Earth, then up to 90% of the sky will be occupied by the luminary. The oceans will evaporate by that time, even the thin solid layer of the earth's crust - the lithosphere - will become liquid.

At the moment of the explosion, a powerful shock wave will eject the Earth and other planets remaining by that time from the solar system. Since there will be nothing to glow - only a small white dot of the former sun will be located in the sky - the temperature on Earth will quickly come, tending to absolute zero.

The usual change of day and night, surface lighting will also be completely absent. The shape of the Earth, which has undergone significant asymmetry after the explosion, will forever remain unchanged, since any tectonic activity in the mantle, the core will stop due to old age and low temperature. There could be trillions of such lone icy planets wandering the galaxy, deprived of a star due to a supernova explosion.

What will happen on Earth if the Sun stops shining?

Despite the fact that this option does not correspond to modern scientific data, such theories exist. Some scientists assume that our star will not become a red giant and will not explode. It is assumed that aging, the sun will shine weaker and weaker, subsequently going out altogether..

A momentary cessation of solar activity will not immediately turn the Earth into a block of ice - our planet also has an internal source of heat - a red-hot core. After 12 hours, it will become noticeable that climate change is taking place. In areas with a sharply continental climate, 0°C will be reached. The oceans and coastal areas will cool the longest - water is an excellent heat accumulator - up to a week.

The lack of sunlight will cause all the plants on the planet, up to the moment of their freezing, to switch to the absorption of oxygen, which will cause its deficiency. Due to the uneven cooling of the planet, hurricane-force winds of the type that blow in Antarctica will begin on the surface - up to 300 kilometers per hour.

A month later, the entire surface of the ocean will freeze, except for the deepest depressions. Fully uniform temperature will be reached after six months. By that time, all gases except hydrogen will turn into ice and life will be possible only in ultra-deep mines.

When exactly will the sun go out?

When will the sun go out? The answer to this question was obtained with the help of modern technologies and a variety of express methods. Everything in the universe has a beginning and an end. Not only plants, animals and people die, but also stars and planets, although their lifespan differs from the duration of the terrestrial flora and fauna.

Mankind has always feared the end of the world. Many scientists have tried to figure out when this will happen by linking Armageddon to the demise of the sun, but when exactly this will happen is unknown. Today, like many years ago, scientists all over the world are wondering that when the Sun goes out and humanity finds itself in this passion, will it be able to live without a luminary on Earth.

How can the sun die?

So far, there is no particular cause for concern, since this will not happen soon. Neither this nor the next generation will see the outcome and will not know why it happened. Perhaps the death of the Sun will become a new stage in the evolution of mankind, as it will force people to cosmic nomadism. Only sports and good physical training will help them in this.

However, it is unpleasant to realize that this Sun can explode, the world will shatter into small pieces, and the trace of humanity on the planet will evaporate. There are many variations on how this Sun will cease to exist. How this can happen, no one knows. Our Sun can simply go out, turn into a nebula, be reborn and become a red giant, after which it will face the fate of a supernova, unable to emit sunlight. Or perhaps this Sun will simply explode and scatter throughout the cosmos.

Over time, the hydrogen contained in the solar core is completely converted into helium, as a result of which the core will heat up and condense, the star itself will increase in size, passing into the stage of a giant red star. There is a theory that hot gases will have to escape into space and move our planet away, which will prevent a catastrophe. According to scientists, this will happen in 5-6 billion years, it is for this period that the reserves of the yellow star will last. The red giant stage lasts not so long, about a hundred million years. After that, the light can simply go out.

By this time, the Earth will be completely uninhabitable. Neither sports nor the high adaptability of a person to changing environmental conditions will help here. The tremendous energy of the revived star will burn the entire atmosphere and surface, which will become an absolute wasteland. After some time, people will have to move to live underground, so as not to burn out at a temperature of 70 ° C. It will be necessary to find a planet in another galaxy and go there, because due to the increased temperature, the rate of decomposition of carbon dioxide will increase, which will allow plants to disappear, without which the existence of people is impossible. Water will evaporate under the increased solar radiation, and the atmosphere will dissipate.

After some time, it is likely that the star will swallow the planets nearby, including the Earth. If it is not affected, then it will subsequently simply move away, and left without attraction, it will leave the Milky Way and begin to wander. Unfortunately, people of this generation will never know what the outcome of this story will be.

After the red stage, this Sun will begin to pulsate intensely, its atmosphere will break out into the Universe, in place of a colossal bright star, a small one will appear, similar in composition to a diamond, which will soon completely cool down, becoming a black dwarf.

If you believe the second theory, then this Sun will simply go out. Each star during its existence evolves from a nebula to a protostar, which turns into a yellow dwarf, which is our luminary. After that, there are two possible events: the star goes out, turning into a blue dwarf, gradually becoming a nebula again. Or he is reborn into a red giant with even more energy. In both cases, for the Earth, such an outcome can be deplorable.

How long will the earth live?

According to scientists, the Sun is slowly but surely approaching the "noon" of its life. Its age, according to computer calculations, is about 5 billion years. The total lifetime of a star is about 10 billion years. If the luminary becomes a blue or white dwarf, a dead star, then it simply cannot give our planet sufficient heat and energy, life will cease to exist not immediately, but gradually.

For some more time the Sun will "burn", but this light will be a phenomenon of gradual cooling. The planet will not instantly be covered with an ice crust, a person will notice this phenomenon only after 8 minutes, and the energy that is stored at the bottom of the oceans will give off heat for some time, it will support life on Earth. The global temperature will drop by about 20°C. Having reached zero soon, it will drop even more, so that in a year it will be -40 ... -50 ° C on Earth, permafrost will set in, only the simplest microorganisms, but not people, can survive in such conditions.

If the Sun goes out, the Earth will be in outer space, the day will cease to change night, the Moon will disappear from the sky, and with it the ebb and flow, a series of earthquakes will pass on the surface of the planet. Photosynthesis will stop, the plants will disappear, respectively, the production of oxygen will stop. The earthlings will still have enough air supply for some time, but this resource will already be limited. For heating, people everywhere will use geothermal sources, as is now practiced in Iceland.

Sun explosion theory

There is a theory of the explosion of the Sun. Many scientists dispute it, saying that the mass of the star is too small for such an outcome of events. Others, on the contrary, support the founders of the version, adding other details. If the Sun explodes, then in time it will be about 6 thousand years. The theory arose from the fact that over the past two decades, the temperature of the solar core has doubled. If this trend continues, the luminary will explode like glass before it goes out. It can spread throughout the universe. After the explosion, a neutron star or black hole is formed. Some experts fear an artificial explosion, when external bodies will cause the destruction of the star at any moment. However, there is no adequate reason to worry about this.

What happens if the sun goes out? No one can give an exact answer to this question, but this will certainly mean the end of the blue planet. But not necessarily the end of humanity, as most people choose sports, so they can easily adapt to any conditions. It is impossible to accurately answer the question of how many people will die as a result of the death of a fireball, and how many will be helped by sports and the desire to live. It is difficult to predict the future exactly, but based on current knowledge of physics, the death of a star will be just that - it will simply cool down.

What happens if the sun's rays go out? No one can accurately answer this question, there are only assumptions: perhaps the world will shatter into millions of small fragments, or maybe nothing will happen to the Earth, and the sports spirit and endurance of people will be able to overcome all obstacles. Or maybe sports on the planet and the desire of mankind to exist here will not be able to overcome and overcome world cataclysms.

What will happen to the Earth if the Sun goes out?

As scientists suggest, in 5 billion years the only star in the solar system will go out. What happens if the sun goes out?

Why the Sun can go out or explode

For the Sun to explode, one condition is necessary - the hydrogen in its composition must turn into helium. But this is not an explosion in the truest sense. Astronomers mean by this phenomenon a decrease in temperature and a simultaneous increase in size. Literally, quasars and entire star clusters can explode.

From the course of physics it is known that with a decrease in temperature, the volume of most bodies decreases. But for the Sun and other stars, this is not the case. Due to the forces of attraction, these objects must be compressed. At the same time, their density increases so much that thermonuclear reactions begin to occur. From hydrogen, helium is formed, and then most of the heavier elements listed in the periodic table.

On the surface of the Sun visible from Earth, the temperature fluctuates around 6,000°C. Stars with such indicators belong to the yellow spectral class. The temperature in the inner layers of the star is about 17 million degrees. Due to this, the celestial body should increase in size.

Dynamic equilibrium sets in when gravitational contraction is compensated by thermal expansion. Nuclear reactions proceed spontaneously, therefore the given temperature data are averaged. We perceive temperature differences in different parts of the surface as dark spots that determine solar activity, including magnetic activity.

Approximately half of the time of evolution of our luminary has passed. To date, solar reserves of hydrogen have decreased by 40% from the original. The burning of this gas leads to a decrease in the mass of the Sun. And this, in turn, to a decrease in the value of the gravitational forces that compress it. The star begins to increase in size, the probability of thermonuclear reactions decreases, the temperature decreases. This is how red giants and supergiants appear. Our luminary is an ordinary star. The same fate awaits him, but it will not be able to go out completely.

What awaits us

It is wrong to say that if the Sun goes out, it will cease to be a source of heat and light. But his physical characteristics will change. When the Sun explodes, it will not shatter into pieces like shell fragments, but will move into another class of stars and turn into a red giant.

When the Sun goes out, its size will increase so much that the radius of the star will exceed the radius of the orbit of Venus. Mercury and Venus will "fall" on it and be swallowed up by it. In how many years this will happen, it is not known exactly. Can the sun swallow our planet? According to scientists, it will remain in its orbit, but how life on Earth will change remains a mystery.

Our star is a source of heat and light. If the Sun goes out, it can be compared to a stove that shines and heats weaker, but is located closer to us.

In 5 billion years the sun will go out. But over a long period of time, life on our planet will evolve, adapting to changing conditions. But for life in today's understanding, the conditions in which it originated are necessary.

There is a hypothesis according to which the Milky Way, which includes our planetary system, will be absorbed by the nearest neighbor, the Andromeda Nebula. Today, both galaxies are approaching at a speed of 120 km/s. Computer modeling has shown that due to the increasing gravitational interaction, the change in the structure of the Milky Way will begin in 2 billion years, i.e. 3 billion years before the Sun goes out. And after 5 billion years, both spiral galaxies form one new ellipsoid.

Astronomy is developing at a rapid pace. It is likely that in the near future there will be new hypotheses describing the prospects of our star and what will happen to the Earth if the Sun goes out.

But what will happen if the sun suddenly takes and disappears? Many people cannot even imagine such a situation. Nevertheless, 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.

gravity

Eternal night

Most plants will die within a few days - but that's not what should worry us the most. The average temperature of the Earth will fall to -17 degrees Celsius in a week. By the end of the first year, our planet will begin to experience a new ice age.

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? Professor of astronomy Eric Blackman is sure that we can easily survive without the Sun. 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

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 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.

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 that we will enjoy ordinary life for another eight minutes before we realize the disappearance of the Sun.
