After what did the earth perish, and why? 5

The process of destruction of the sphere must have nothing to do with man, because man will perish before the destruction of the earth, and man cannot destroy the earth, and the earth will age and die like other stars.

People imagine themselves to be great, in fact, how small we are, our ancestors invented tools to conquer nature, we invented ** to conquer ourselves, our thinking became sluggish, our limbs became weak, and we were finally killed by ourselves.

Reason 1: According to scientists' speculation, in 5 billion years, the sun will first become a red giant star and hit the nine planets in turn, and finally hit the earth, and then the sun itself will become a white dwarf and gradually disappear into the universe. (There is a certain scientific basis).

Reason 2: By 2050, oil will disappear.

Reason 3: The atmosphere has been damaged.

Reason 4: The water flow is decreasing and polluted.

Reason 5: There is a serious shortage of trees.

Two. First, 5 billion years from now, the Sun will become a red giant instead of a black hole due to energy depletion.

Second, the disappearance of oil does not mean the destruction of the planet. There are also hydrocarbons such as combustible ice, natural gas, etc., or the use of plants to make oil, which is similar to oil.

Third, the ozone layer is destroyed, not the atmosphere, if the atmosphere is destroyed, you would have died a long time ago, and you will still be here to surf the Internet?!

Fourth, can't water pollution be artificially purified? But it's really human fault.

Fifth, there are indeed fewer forests, and if there is a severe shortage, can you still breathe?

After about 4 billion years, the Sun's internal hydrogen fuel will run out, and the Sun's interior will collapse, and then its volume will expand rapidly, becoming a "red giant". Mercury and Venus will be engulfed, and even if the Earth is not engulfed, the surface temperature will reach 1,000 degrees Celsius, and all living things will be destroyed.

In about 4 billion years, the Sun will run out of hydrogen for nuclear fusion and start nuclear fusion of helium nuclei, at which point the Sun will begin to expand, and in about a billion years, the Sun's periphery will expand beyond the present-day Mars of the Solar System, which will swallow up celestial bodies including Mars, and of course the Earth will be no exception, and the Earth will definitely play at this time (if not including the impact of a fairly large asteroid on the Earth during this period).

It's too early for the Earth to die, but humanity will die soon by its own hands, all of it, desertification, melting of Antarctic glaciers, land and oceans, ozone layer depletion, human cancer, and these problems will eventually be the end of humanity and not the end of the planet.

The earth and the moon fell in love, and the cave house perished that day

LZ don't worry, our generation can't wait for the end of the world.

That's when the ecological environment is being destroyed by people.

The ecological balance has been destroyed.

The earth, like people, is alive, and there is life and death.

We humans have "birth, old age, sickness and death", and the earth also has a life cycle. It's just that the lifespan is billions of years, and we can't detect it. Planets, like people, not only have age, but also have longevity.

According to astronomers, the age of the universe is 13.7 billion years old, and the age of our solar system is about 4.6 billion years old.

When we say planets in the sky, we mean stars that shine themselves, that is, planets that resemble the sun. Earth, Mercury, and Jupiter, among others, are planets that revolve around the Sun. Cosmologists once agreed that the age of the universe was about 15 billion years, but this number was later slightly lowered by observation.

The universe originated from particles smaller than atoms and was born in a single large**. ** The red-hot energy generated cools down into matter. The gravitational pull attracts subatomic particles into clusters of matter, forming simple atoms such as helium and hydrogen, which become hotter and larger as the gravitational pull increases, giving birth to planets.

When a star passes its long prime of youth, main-sequence star, and enters old age, it will first become a red giant. During the giant phase, the star will expand to a billion times its size. It is called a "red" giant because as the star expands rapidly, its outer surface is getting farther and farther away from the center, so the temperature will decrease and the light emitted will become more and more reddish.

Many of the brightest stars we see with the naked eye are red giants. Once a red giant is formed, the final outcome will be a white dwarf. In 5 billion to 6 billion years, the Sun will become a red giant, 50 times larger than it is today, and will expand into its current orbit.

At the end of the planet, there will be two things: a small star such as the Sun will form a "planetary nebula", which is essentially a crust of dust and gas thrown by a dying star. Massive stars will form "supper nova" explosions, which can form new planets, that is, planet births.

The irrational use of resources by human beings and the pollution of the environment.

Because humans cut down a large number of trees, destroying the natural ecological environment.
