Maybe you know the earth’s past, but you can’t guess the end of the earth! Where is the future of the earth

After the mid-20th century, after studying various rocks and fossils, scientists speculated that the earth was born about 4.6 billion years ago. We probably all know the time when the earth appeared, but we should know that everything has an end, and our earth is no exception. What about the future of the earth?

Scientists believe that in the past 500 million years, the earth has experienced five mass extinctions, including Ordovician, Devonian, Permian, Triassic and Cretaceous. The terrible thing is that the sixth extinction is coming quietly.

Looking back at the past five extinctions, two are related to astrophysics.

The first time occurred in the Ordovician. Two neutron stars 6000 light-years away from the earth played “kiss”. As a result, they couldn’t split and collided with each other, bursting out a “spark of love”. Gamma rays swept the earth, and the Nautilus, trilobites, star turtle, Bantam turtle and other species ended.

The second time occurred in the Cretaceous, when an asteroid with a diameter of 10 kilometers hit the earth, and the dinosaurs who dominated the earth for 160 million years withdrew from the stage of history. At the same time, most of the creatures on the earth were extinct, and the life of the earth began to shuffle again.

It was not until 30 million years ago that the ancestors of mankind appeared. After a long period of evolution, two or three million years ago, human beings finally began to make great changes, and primitive human beings gradually possessed wisdom.

After 2000 years, ancient human civilization appeared, including two river civilization, Nile civilization, Aegean civilization, Yin Shang civilization, Olmec civilization, Atlantis civilization and so on. More than 200 years ago, modern human civilization began to be born, forming the vibrant scene of the earth today.

From this, we can see that we know more about the past of the earth in general, but what about the future of the earth? In fact, from the previous five mass extinctions, it can be found that every time the earth goes through a period of time, there will be a biological cycle, and every time a species goes extinct, there will be new species, and this material is even more intelligent and advanced than the original, such as us.

So what happens to the earth after the next extinction? Will humans be replaced?

Scientists speculate that the sixth extinction of the earth may take place 1.4 million years later, and Gliese 710 is quietly approaching the solar system at a speed of 3.4 kilometers per second.

Gliese 710 is a red dwarf star, located in the constellation Serpens, with a diameter of about 900000 kilometers. Because of its huge diameter, it is likely to pass through the Oort cloud and disturb all the celestial bodies in the solar system after entering the solar system. These celestial bodies rush to the earth, making the earth face great disaster, and the earth will also go to the edge of destruction.

And human beings must find a way to deal with all this. Maybe interstellar migration is the best choice! What do you think of this? Welcome to comment area.
