How many days will the earth live, how many more years will the earth live

Scientists say that the earth is 4.6 billion years old now, and it is only in its middle age, and it is still very young, so you don't have to be afraid, the earth can live for a long time!

The earth has passed hundreds of millions of years, and now it is in the prime of life, so don't be careful about this.

It is speculated that many people will die on December 27, 2012, and there is also a saying that the asteroid will hit the earth in a few years.

The current main-sequence phase of the Sun has been going through about 100 million years through computer simulations of stellar evolution and cosmochronological models. According to research, the rapid collapse of a cloud of hydrogen molecules 100 million years ago formed a Taurus T star of the first generation of the first generation, that is, the Sun. The newborn star orbits in a near-circular orbit about 27,000 light-years from the center of the Milky Way.

The Sun has reached middle age in its main-sequence phase, during which the stellar nucleosynthesis reactions that occur inside its core fuse hydrogen into helium. At the core of the Sun, more than 4 million tons of matter can be converted into energy every second, generating neutrinos and solar radiation. At this rate, the Sun has so far converted about 100 Earth-mass matter into energy.

The time when the Sun is the main-sequence star lasts about 10 billion years. The mass of the Sun is not massive enough to explode into a supernova. In 5,06 billion years, when the Sun's hydrogen is depleted, the core is dominated by helium atoms, and the Sun will transform into a red giant, expanding its outer layers when the hydrogen in its core is depleted, causing the core to shrink and the temperature to rise.

When its core temperature rises to 100,000,000 K, helium will fuse to produce carbon, which will enter the asymptotic giant branch, and when all the helium in the Sun is converted to carbon, the Sun will no longer shine and become a dead star (Black Dwarf). The ultimate fate of the planet is not yet known. When the Sun becomes a red giant, its radius can exceed 1 AU, which is 260 times the current radius of the Earth beyond the Earth's current orbit.

However, by then, as an asymptotic giant branch star, the Sun will lose about 30% of its current mass due to stellar winds, and the planet's orbit will be extrapolated. For that reason alone, the Earth may be spared from being swallowed by the sun. However, new research suggests that the Earth will still be swallowed by the sun due to the effects of tidal action.

Even if the Earth could escape the fate of being melted by the Sun, the water on Earth would evaporate and the atmosphere would escape. In fact, even when the Sun is still a main-sequence star, it gradually becomes brighter and the surface temperature rises slowly. The rise in the sun's temperature will cause the Earth's surface to rise in 900 million years, making life as we know it impossible to survive.

In another 1 billion years, the water on the Earth's surface will disappear completely. By that time, humanity would have been extinct.

There are three scenarios:

Asteroid impact: The probability of the Earth colliding with other stars in the universe is currently being calculated, and the asteroid, named 1999 RQ36, has a 1 1000 chance of hitting the Earth before 2200, but the impact is most likely to occur on September 24, 2182.

Humanity perishes on its own.

Solar activity is intense. After 5 billion years, the sun will first become a red giant, expand in size, and then swallow Mercury, Venus, Earth, and Mars in turn, and the earth will not be able to live at that time anyway.

There are roughly three ways for the earth to perish:

Colliding with a sufficiently large celestial body and thus disintegrating, such an event has the lowest probability and is almost impossible.

Some kind of event could occur during the evolution of the Sun into a red giant, with a powerful solar wind pushing the Earth into deep space. The probability is low.

In the late solar period, due to tidal forces, the earth was torn into pieces and orbited around the sun and finally fell to the sun, which is the most likely.

Answer: The first case is unknowable; The second scenario should be to start gradually after 3 billion years and finish around 40 to 5 billion years later, as for where the Earth drifts and what celestial bodies will eventually be captured or destroyed; The third scenario will happen about 4 billion years from now.

As long as the sun lives, the earth will probably live as long as it wants. In 50 6 billion years.

So it can be said that even if I love you from today, I can only love you for another 5 billion years.

If the Earth were not hit by celestial bodies from inside and outside the solar system, or torn apart by the gravitational pull of a black hole neutron star, it would live for about 4 billion years, after which our Sun would expand into a red giant star and burn the Earth to ashes.

Needless to say... Anyway, the earth won't end in your lifetime, and it doesn't matter to you whether the people after you die or live.

5 billion years, as the sun expands due to fuel depletion, engulfing the earth. The sun will take over most of the sky, and of course, we don't exist anymore.

Scientists** The life span of the sun is 10 billion years, and now it has passed 5 billion years, and in 5 billion years the sun will become a white dwarf, I will talk about the details later.

The current age of the Earth is 4.6 billion years, and if we do not take into account the influence of human or other factors on the Earth, the result of the Earth's life will be swallowed up by the expanding sun. The details are also said later.

So what is the human factor? That is to say, human beings have wantonly deforested, polluted water resources, emitted polluting gases, and even conducted nuclear tests. If these are serious, they will have a devastating impact on the planet.

There are other factors, and the other factors are comets, asteroids hitting the Earth, and so on. It could also lead to the destruction of the planet.

Without further ado, let's talk about the evolution of the sun.

The life span of the sun is 10 billion years, and now it has passed 5 billion years, and in about another 4 billion years, the hydrogen used for nuclear fusion in the interior of the sun will be exhausted, and at the same time the nuclear fusion of the helium nucleus will begin, at this time the sun will begin to expand, and in about a billion years, the outer periphery of the sun will expand beyond the current solar system Mars, and then the celestial bodies including Mars will be swallowed, and of course the earth will be no exception, at this time the sun will be on the verge of death. The Sun then undergoes a gravitational collapse and becomes a celestial body the size of the Earth, called a white dwarf......At this point, the sun will die, and our planet will cease to exist.

Of course, don't worry, by that time, human science and technology will be unimaginably advanced, and I am afraid that we will have already left the earth and moved to other planets.

I played all of the above myself, and you only give 5 points ......

4,05 billion years; Because from the carbon-12 detection, the earth has gone through 5 billion years so far, and the sun and the earth were born in the solar system almost at the same time, and the sun has passed 4 billion years and entered middle age, similarly, the earth has 405 billion years of life.

It will take about 5 billion years, but there may be accidents during this time, such as natural disasters, epidemic collisions, or the depletion of the earth's resources, which will cause changes in the earth. But scientists have determined that without these accidents, they could have lived about 5 billion years longer.

5.1 billion years, when the Earth, if it had existed at that time, would have been swallowed up by the Sun's growing size to become a red giant.

If the earth continues to change as it is now, there are still 5

000,000,000,000,000,000,000,000,000,000,000,000,000,000,

First of all: the earth is not a living thing, and there is no such thing as living or not living.

If we talk about the longevity of the earth. It is estimated that the Earth has survived for 4.6 billion years. Scientists believe that if the Earth is allowed to move freely, it may exist forever, but if other external factors interfere with it, the Earth may have an end of life.

The external factor is the sun in the first place, because it is the closest planet to the earth and can have a destiny on the right earth That is to say, all the energy and power on the earth come from the sun, and once the sun has three long and two short, it is bound to affect the earth. Before the 30s of this century, people always thought that the sun would one day burn out, turn from white to orange and then to red, and finally become a dark star that was silent, but its brilliant life. In the 30s, when physicists learned the mystery of the sun's light, the situation was very different.

It turns out that the Sun's energy comes from its thermonuclear reactions, and the Sun's lifetime will pass through the gravitational contraction phase, the main-sequence star phase, the red giant phase, and the compact star phase. The main sequence phase is the period of stability of the Sun. This phase will last for 10 billion years.

At present, the sun is only halfway through and is in middle age. Once the Sun reaches the red giant stage, then the end of the Earth is coming. Of course, this is billions of years away.

Are there any other factors besides the sun's interference with the earth? Some scientists believe that the Sun may have a brother, a companion star of the Sun, which orbits the Sun day and night, and turns to the closest place to the Sun every 26 million years"Make waves"Its strong gravitational pull will cause a large disturbance of many comets, and 1 billion comets will be on a rampage in the solar system, and the Earth and other planets will become these comets"Target"。If the mass of the comet that collides with the Earth is large enough, the consequences are unimaginable:

the extinction of light organisms and the drastic changes in ecology; Heavy landslides and earth cracks, the earth"Broken bones"。However, this solar companion star, which could bring misfortune to Earth, has not been discovered, although many scientists believe it exists.

The Earth can live for a long time, 5 billion years.

How long can humans live on Earth: It depends on whether humans will die or not, and there may be a world war, and humanity will be destroyed in an instant.

After the destruction of humanity, the earth will still be full of life. Don't worry about the planet. Let's maintain world peace and worry more about our fate.

If there are no external causes, the Earth can survive forever in the universe, but the Sun is a star, and after 5 billion years, it will expand violently due to the exhaustion of energy, and it will be able to pass through the orbit of Mercury, and the Earth will eventually be swallowed by it.

Human behavior is also important, the development of modern nuclear **, as well as environmental problems, will have a threat to the earth, which in turn will affect the life of the earth. How long does the Earth live? I have wondered countless times about how long our blue planet can be blue, as we all know, the earth's resources are limited, coupled with the wanton destruction of human beings, pollution ,..
