How many more years can the earth survive How many years can the earth survive

The earth has been living for 4.6 billion years now, and in 5 billion years the sun will be **, and the earth will also suffer, so the earth will be over in another 5 billion years

This is not yet possible at the current level of scientific competence. However, it is known that the current age of the Earth is 4.6 billion years. The earth belongs to the solar system, and its fate is of course closely related to the sun, and once the sun is destroyed, the earth will of course have nowhere to live.

The reason why the sun can heat up is because of the thermonuclear reaction inside it, which consumes a lot of the sun's substance, and as the sun ages, it will also consume its own heat and eventually die, and then the earth will be gone.

However, the sun is still only in middle age, and it is still billions of years away from destruction. Of course, there are many other factors that contribute to the safety of the planet.

Someone once asked the British astronomer Jones, "How many more years will the Earth exist?" "It's a difficult question to concrete, and even if we can figure out how many billions of years it will exist, it's hard to say convincingly.

Jones said, "You are like, there is a majestic mountain, and a little sparrow pecks at this mountain leisurely, and the earth can exist as long as it takes for the little sparrow to peck at this big mountain." ”

On the other hand, if there is an accident, such as war or other planetary impacts, it may be in the near future, so we need to take care of our planet and make our planet survive longer with a strong domestic and peaceful way.

According to the current battle array and the greenhouse effect, and the selfishness and waste of human beings, it should not take 300 years. Up to 500 years.

n years, even if the earth is **, but those substances are still there, slowly evolving, and new planets will still be born.

It's hard to say if the 2012 prophecy is true,..Scientist budget, probably a billion years.

The day the sun will die, 10 billion years later.

In 2012, it became known. Hope. Thank you!

Earth's year 2060 will be a flashpoint. The landlord checks the relevant information.

Don't ask if it's so far away, the future will be unpredictable, live a good life today.

I'm sorry. You can't see the Earth dead.

Sure you hang first.

Hurry up and go to Mars, the Earth will not be.

Earth, as a time-lapse planet, is not destroyed for no reason, but it is the solar system after all.

The satellites of the Earth, the existence of the earth for a long time depends on the sun, and indeed there is a more exact time of destruction. It has something to do with the sun.

The life of the sun is about 5 billion years, and after 5 billion years, the helium element on the sun.

Exhausted, the Sun will also enter the stellar old age.

First, the Sun will explode in size and become a red giant. It will swallow the Earth into the Sun, and the farthest will swallow Venus.

Planets swallowed up by the sun will be destroyed.

Then, the Sun shrank dramatically, shrinking into a white dwarf.

As for the Earth itself, it will not destroy itself unless it is hit by a very large asteroid that causes the Earth to shatter. Of course, nuclear war.

The destruction of the earth's magnetic field, rapid changes in atmospheric composition, climate, etc., will also lead to destruction, but this generally also refers to the destruction of human civilization, not to the destruction of the earth itself.

If human beings do not have a self-destructive life, they should be counted according to the age of the sun.

Because without the sun's rays, we wouldn't be able to survive. Because solar energy is the energy of all things**, it is impossible for us to create another one.

Almost all of the energy of our earth comes from the sun, and oil is the result of ancient creatures, and ancient creatures also depend on the sun to sustain and grow. The same goes for coal.

Based on the age of the sun, it seems that it can burn for another 4 billion to 5 billion years. If humanity had found a new place to live, I wouldn't know.

Scold. That's God. If I could say that clearly, then I would be a prophet.

In 5 billion years, the Sun will become a red giant and engulf the Earth, and the Earth will no longer exist.

Scientists believe that if the earth is allowed to move freely, it may exist forever, but if other foreign 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 that 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 upheaval of 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.

From which side of space will the Earth be destroyed by a blow from the space? When will the earth die? However, the length of time human beings can survive on the earth depends on the changes in the earth's environment and whether the resources can sustain human needs.

Although solid planets can theoretically exist for very long periods of time, this must be done without a large number of external interference.

However, almost every planet is affected by the stars of its star system, and some planets that are closer to the star will even be swallowed by the star, such as our Earth.

Scientists have examined the sun and found that about 5 billion years have passed since its birth, and the sun is now in its "youth"! For a long time to come, the sun will provide a steady supply of light and heat to the solar system, but the sun will eventually come to an end.

In about 5 billion years, the Sun's nuclear fusion will gradually cease, and only the core region of the Sun's inner socks will meet the conditions for nuclear fusion. At this point, the Sun will be burning with thermonuclear fusion inside it, releasing a large amount of atomic energy, and then rapidly expanding into a red giant.

Of course, according to the current development rate of human civilization, not to mention 5 billion years, or even only a few million years or even less time to fly out of the solar system, therefore, the disaster in 5 billion years is not a problem for mankind at all. And, for our current humanity, it makes no sense to talk about what will happen in 5 billion years!

It is known that living things have been living on Earth for tens of millions of years.

Scientists have calculated that the earth is more than 4 billion years old through the trace amounts of radioactive elements that are ubiquitous in the earth's crust, and how long can the earth live? Scientists believe that the life span of the sun is 10 billion years, and the age of the earth is now 4.6 billion years, if you do not take into account the influence of other human factors. The end of the Earth's life will be swallowed up by the expansion of the Sun.

Or other asteroids hitting the Earth could also cause the destruction of the Earth.

Scientists have studied that in the near future, the sun will radiate more heat, which means that the earth will be hotter and will not be able to retain water. Scientists at the University of Colorado used a 3D computer model to simulate the impact of different factors on the Earth's habitability, and entered three variables, land, sea and air, to arrive at different numbers than before. According to the figures, it will take 10 to 2 billion years for humans to leave the Earth.

How long can human beings on Earth survive in the shadows?
