When will the earth be destroyed, and when will the earth be destroyed

The earth will not destroy people, people will be destroyed, the earth's environment will eventually be bad enough to destroy human beings, and then the earth will enter the next cycle, a long recovery cycle, this cycle can be tens of millions or even hundreds of millions of years, the earth's ecology will return to its original state, the earth's environment will once again be due to the vicissitudes of the orogenic movement, new life will begin to be born, from low to high, into a long cycle of life evolution, hundreds of millions of years later, human beings who have evolved to reach the brain begin to appear, and then human society has entered a period of rapid development. Human beings have developed civilization to an unprecedented height in just a few thousand years, but this civilization has entered a period of rapid deterioration at the expense of the environment, climate and resources, and finally the earth's resources are depleted, the earth's environment and climate are extremely harsh, the earth collapses, and human beings are destroyed. The Earth has entered the next cycle, a long cycle of self-healing.... …

The earth can still carry out such a cycle n times....This kind of estimation is not fabricated out of thin air, and before this, some scientists said that the earth may have had n prehistoric civilizations, and there was not a certain country that unearthed fossilized color televisions in the last century... …

Except for accidents and wars, it is the same as the life of the sun.

There's no point in you worrying about this, it's definitely going to outlive you.

1 All about 5 billion years later. The destruction of the Earth should be due to a star collision or the engulfment of the life cycle of the Sun, which will be accompanied by **. The sun has about 5 billion years to live.

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 sun is expanding, and the habitable zone of the solar system is constantly moving outward, so one day the solar system will no longer be suitable for life on earth.

You go and build a giant nuclear bomb and launch it...

Or wait until 2012...

The earth will not change much during your lifetime.

We all know that the sun heats up and emits light, and the sun emits light by consuming its own nuclear energy, but it is getting brighter and brighter. As the solar core hydrogen is depleted, it shrinks slightly, causing the core pressure to increase and the temperature to rise. In 1 billion years, the sun will be even hotter enough to make Earth's climate unbearable.

In the future of 3 billion years, a critical point will be reached where the sun will be 40% brighter than it is now, so all the water on the earth's surface will be evaporated, the oceans will disappear, and the world will become a purgatory under the scorching sun. If humanity is helpless, over time, the entire planet is likely to turn into a molten and hot magma world.

Maybe today, maybe tomorrow. Still, by my guess, you won't be able to catch up.

Soon! Today, 4.6 billion years later, let's hurry up and lay the covers.

At present, it is generally believed that after 5 billion years, the sun is gradually dying, and when the hydrogen fuel required for the fusion of hydrogen nuclei into helium inside the sun is exhausted, the fusion reaction stops, the external pressure drops, and the sun contracts, resulting in a further increase in the internal temperature, starting the reaction of helium fusion into heavier elements such as carbon, and releasing huge energy, so that the sun expands to the vicinity of the earth's orbit, and the surface temperature of the earth will be as high as more than 2000 degrees even if the earth does not vaporize rapidly. Finally evaporation disappears.

Mercury and Venus will also be killed).

In fact, there is no need to wait until that time, according to the latest research: 1 billion years later, when the sun's luminous intensity increases to a certain level, the earth's temperature rises to a very high level, the ocean evaporates, and the earth becomes a lifeless desert planet.

When the earth will be destroyed is not predicted exactly, some people say on the Internet that Wenchuan ** is expected, so why not prevent it before the earthquake? Some people say that the earth was destroyed on December 21, 2012, but there is no scientific basis. There are natural and man-made disasters for people, and there are also miracles.

It's the same with the earth, and it doesn't know when it will die. Normal people should live to be more than 100 years old at most, if you don't protect yourself well, maybe something will happen, or you will die within the age of 100. The earth is the same, everyone should protect the environment, take care of the environment, do not patronize their own interests to damage the environment, let the earth live a healthy and long life in a beautiful environment, so that our children and grandchildren can reproduce and prosper on the earth.
