If the Earth is finally destroyed, what are the reasons for its destruction?

There are several possibilities for the destruction of the Earth, first, the destruction caused by an asteroid impact, second, the Earth self-destructs at the end of its life, and third, the Earth is engulfed due to the death and expansion of the sun.

I think it has a lot to do with the fact that humans don't care for the environment, and they cut down and trample indiscriminately, waste water resources, and throw away garbage at will.

If the world will end in the future, what will cause it? Expert: Self-destruct!

Akatsuki organized to travel to our world and was seconds.

The earth will be destroyed along with the universe, and the universe will also face death, because there is a large amount of dark matter and dark energy in the universe, and these dark matter and dark energy are the main culprits that cause the expansion of the universe.

When we watch the sun rise and set every day, look at the stars in the sky, and look at the cloudy and sunny moon, will we feel the beauty and wonder of the earth, and have we ever thought that the earth will exist endlessly? In our eyes, the earth seems to be "invincible", although there are often disasters, tsunamis, floods and other disasters, but at least the earth is not damaged, and it is still our home. However, according to astrophysics, life on Earth may not die out in a billion years, but the destruction of the Earth can happen at any time in these billion years, and the factors that make the Earth destroy are so terrible.

Figure 1 3 First of all, the important factor for the existence and continuation of our life is the position of the sun and the distance between the earth and the sun. However, the energy of the sun is great, it is just a star, and sooner or later the star will perish. Now that the sun is in its middle age, in the future, the amount of hydrogen in the sun will gradually decrease and be converted into helium, causing helium to accumulate and the volume of the sun to expand.

This may cause the earth to be pulled in by the sun, and in this way the earth will be reduced to ashes; Or deflect the earth from its original orbit and float in the vastness of the universe until it freezes to death.

Figure 2 3 Secondly, black holes in the universe have always been the focus of scientists' research and exploration, and it is only known that the density inside the black hole is extremely high, and it is in a wandering state, if it is unfortunately absorbed by the black hole, then the possibility of escape is very small. Even if a recoil black hole is not encountered, it is possible that other disasters could have moved the Earth away from the solar system or closer to the Sun.

Finally, and the most likely, is the impact of other asteroids. It is as if an asteroid collided with a large asteroid 4.6 billion years ago to form the current Earth and Moon. Moreover, just after the formation of the earth, it was also hit by an asteroid, which made the ocean boiling all year round, but there was no advanced life at that time.

Figure 3 3 Therefore, the seemingly solid earth is actually facing various dangers every day, and although there is no sign of destruction yet, the destruction can only be completed in an instant, so while the earth is still functioning, while we can still see the rising sun and the starry sky at night, we cherish every day.

Student: The earth will be destroyed in the distant future.

Since its birth, our universe has been expanding, and it has its own laws of development, which is in line with Einstein's theory of relativity.

The universe originates from a "singularity" of infinite mass, but it is not a point, but a matter of infinite mass and infinitely small volume, and this substance does not apply any philosophical laws. There is no concept at this point.

At a certain point in time, this point "collapses" due to the infinite size of the internal mass and the infinitely small volume, the entire mass system collapses, and our universe is born.

The collapse of the "singularity" in the form of light, According to Einstein's mass-energy equation, light can convert energy into mass when it interacts at the speed of light, so that the simplest atoms are slowly produced, and in this way, simple atoms produce higher atoms, and our universe finally produces a rich number of atoms, and under various interactions, various atoms interact with each other to produce objects, gradually produce our earth, gradually produce life, and gradually have you and me。

But our universe will continue to develop in this way, our earth is in a state of equilibrium, but our sun is in a state of development, you see its main atoms are still hydrogen atoms and helium atoms these lower atoms, because our sun is very massive (more than the Schwarzschild radius), it will constantly use the huge energy it produces as the origin, constantly produce each other, produce new atoms, because the mass of the new atoms is very large, so our sun will develop more and more massThe volume is getting smaller and smaller, and gradually if it continues to develop like this, our sun will swallow up its planets (including our earth) under certain conditions or collapse, and the sun at this time is what we often call a "black hole", and a "black hole" is a "corpse of a star".

So: the earth will inevitably be destroyed in the distant future (almost unexpectedly) due to the death and collapse of the sun, but you don't have to worry about human beings, who may have already migrated to the extraterrestrial world at that time!

What do you think is the reason why the earth will be destroyed?

Answer: Natural disasters are terrible, and man-made disasters are a hundred times more terrible.

The Earth should be destroyed by a stellar collision or the engulfment of the life cycle of the Sun, which has about 5 billion years to live. The Earth is speculated to have survived for 4.6 billion years, but how long will it live?

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 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.

If humanity on Earth suddenly disappears! Will the earth be destroyed by this? Or is there a new civilization?

If the earth were destroyed, humanity would cease to exist, this result is certain.

If the earth destroys humanity, whoever eats it will perish, but after hundreds of thousands of years, there may be human beings.

It is possible, but it will take hundreds of millions of years of constant change to produce new species of life.

If the earth is allowed to move freely, I am afraid that it will exist forever, but if other external factors interfere with it, the earth may have its end of life.

Quite possibly. Because scientists point out that there is water on Mars, where there is water, it is possible, and there is life.

If the Earth were to be destroyed again, humanity might not survive either.

If the Earth is destroyed, humanity will also perish, but there will also be a chance that new humanity will emerge.

At this time, there will be no human beings, the earth is destroyed, how can human beings exist.

This is not necessarily, if there are the right conditions, then there will still be human beings.
