When the earth perishes, what will humanity do, and what will happen to humanity when the earth disa

We don't have it anymore.

How long is the life span of the earth?

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 and turn from white to orange again.

turned red, and finally turned into 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 life will pass through the gravitational contraction phase, the main order.

Star phase, red giant phase, and 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 every 26 million years, turns to the closest place to the Sun"Make waves", its strong gravitational pull will cause many comets.

There are 1 billion comets that will rampage through 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 one may give ground.

The planetary solar companion has not been discovered, but many scientists believe it exists.

Before the earth is destroyed, humanity will disappear. It is estimated that the sun will engulf the earth in 5 billion years, and humanity will disappear in 1 billion years!

Five ways for the earth to eliminate humanity, the first is to get rid of the moon. The Moon is the closest celestial body to our Earth, only 380,000 kilometers away, and it is also the only satellite of our Earth. In our daily cognition, the moon or the moon does not seem to have a particularly big role for us, it is just a slightly bright object at night, and at certain times it is our feelings, nothing more.

However, in fact, the Moon is particularly important for us humans and for the entire planetary ecosystem. On the one hand, the Moon is a natural barrier to the Earth, which has resisted many meteorites for us in the past 10,000 years, and at the same time, the tidal effect of the Moon on the Earth will affect the survival, reproduction and evolution of marine life. Once our planet loses the moon, it will be a huge disaster for marine life.

In addition to the tidal effects of the oceans, the gravitational pull of the moon also affects the flow of our Earth's atmosphere, which in turn affects the environmental changes of our planet. Of course, one of the most important effects is that the Moon is able to maintain the existing balance. Because the mass of the Moon has reached enough to affect the operation of our earth, it is because of the existence of the moon that our earth can maintain its current state of motion.

Once the Earth throws the Moon away, the tilt angle of the Earth after losing the Moon will change, and the rotation and revolution speed will also become faster, and this change will definitely be a catastrophe for life on Earth. Therefore, from a certain point of view, without the moon, there would be no life on the earth, and the earth without the moon will no longer be suitable for life.

What is the definition of the end of the earth? Is the earth **? Or is it compressed? What kind of destruction is it?

First of all, what is the demise of the ball?

Humans are living beings on Earth. This organism is material, made up of all kinds of matter on earth. It has evolved over a long period of time to the product of today.

Matter is indestructible. The material that makes up the earth is also imperishable. However, it can be transformed into another form.

When there were no humans, the earth already existed.

When there were humans. The earth is known to man.

After the extinction of human beings, the earth will return to those material bodies, and human beings cannot occupy the highest level of life on the earth forever.

Because in ancient times, the creatures on the earth were not ruled by humans, but by other animals. Based on this, it can be realized that after the death of human beings, it will be a superior creature that will rule the earth.

Now let's talk about time, the earth has existed for about 5 billion years, and there will be 5 billion years to live. Because in about 5 billion years, the sun will burn out. The Sun will turn into a red giant.

When the Earth's orbit enters the interior of the Sun, the matter on Earth transforms into another form. A gaseous nebula. These nebulae then wander around the universe, cool, and then regroup into new spheres.

A new world has been created, and under the right conditions, there may be substances that become organic matter, enter living things, and evolve new species.

What about humans? Humans cannot rule the planet forever. Humans have ruled the earth for about 1.7 million years.

However, for the 5 billion-year-old Earth, 1.7 million years is just a snap of a finger. If you take the development of the earth in a 10-minute movie, human beings only have about 3 seconds of footage.

Objectively aware of ourselves, we are inhabitants of the earth, not masters. The human category is too noisy to exist a little longer.

In the early years, there were many plants on the earth. Absorb CO2 in the atmosphere, transform oxygen, make human beings exist, ants on the earth eat plants, produce methane, in the future oxygen runs out, there are no plants, then there must be a creature that can use methane as a breathing creature to rule the earth.

Soon after the disappearance of humans, cities will be covered with vegetation.

Houses will gradually collapse.

A single lightning bolt can cause a fire in an alluring city.

Water pipes will be weathered and rain will be rained and so on, cities will be covered with water around 5,000 years ago, nuclear warhead shells will be corroded, nuclear materials leak 20,000 years later, nuclear winter will lead to the arrival of a new ice age, urban buildings will be covered by glaciers 1 billion years later, the earth will become hotter because the sun is getting bigger, because the sun is constantly expanding.

During this time, the species on Earth will complete their evolution and adapt to the hot Earth.

If a highly intelligent creature evolves, it will rebuild the city during this time, but will eventually destroy or leave the Earth.

Five billion years later, the Sun's constant expansion has engulfed Mercury and Venus, and the Earth will become a sea of fire until it is swallowed up by the Sun.

Trillions of years later, the Earth ceases to exist. Maybe some dot waves can float in the universe. These signals may be received by aliens or highly intelligent beings who have escaped from Earth.

What will become of the Earth when humans disappear? The answer given by the scientist is sad!
