There are many different views on this issue. In 1745, the French biologist Buffon proposed a hypothesis about the origin of the earth: a long, long time ago, there was only the sun in the universe, and there was no earth.
Once, a very large comet collided with the sun by chance, and the sun was knocked into some pieces, which revolved around the sun, and finally formed several major planets, including the earth. This hypothesis is a major breakthrough in the question of the origin of the earth. Later, the German Immanuel Kant published a new hypothesis that both the earth and the sun originated from the nebula matter in the universe.
"Originally, the solar system was just a cloud of gas and dust floating in space," he said. It could be a nearby star** that released a series of shock waves that caused the clouds to pile together under their own gravity, gradually forming a huge disk.
In this disk, gas and dust are in constant motion, and matter is constantly falling into the core of the disk, which becomes hotter and denser than the edges. This energy-intensive core is the prototype of the sun. At the same time, the dust particles that swirl around the core also begin to accumulate, first into small rocks, and then, like snowballs, into a larger cobblestone.
Before these cobblestones turned into large stones with a width of several thousand meters, they were called MSIs. Many microstars collide with each other, eventually forming four inner rocky planets: Mercury, Venus, Earth and Mars, as well as the rocky cores of several "atmospheric clusters":
Jupiter, Saturn, Uranus, and Neptune. In the early days, Earth was just a bare planet, a bit like the Moon today. Because there is no protection from the atmosphere, it is constantly bombarded by meteorites.
Meteorites are millions of rock fragments that move rapidly around the young solar system. These meteorites hit the ground, and some chiseled out huge craters. This incessant bombardment caused the earth's rock surface to melt; The planet turns into a round, extremely hot ocean of lava.
Eventually, the bombing stopped, and the Earth's surface cooled, but the newly formed solid surface also encapsulated the gases inside. As the pressure mounts, hydrogen, carbon dioxide, and nitrogen begin to eject through the surface of the volcano. Thousands of volcanic eruptions are raging across the globe.
The various gases that are ejected come together to form a new atmosphere that hangs over the planet. Soon, as the sun heated, the clouds cooled and rain began to fall, and it was certainly the longest heavy rainstorm ever recorded on Earth. Water poured down from the sky for thousands of years until the Earth's low-lying basins were filled up, forming the land and sea of our planet today.
In short, there are many theories about the origin of the earth, but how exactly the earth came to be remains a mystery.

What would happen to the Earth if its core cooled down?
-
Because there is hot magma in the core of the earth, and there is also the mantle, crust and other aberrations as a protective layer, so there is no cold cover. Quiet skin energy** is that there is a lot of hydrogen in the earth's core, which produces radioactive elements.
-
Because the temperature of the earth's interior is very large, and the temperature of the earth is constantly rising, it will cause the inner core to not cool. The energy comes from the earth, and the rotation comes from the nuclear energy radiation inside the earth.
-
Because the core of the earth is still active, it produces radioactive elements, so the temperature is still very high, there is no cooling, and the energy comes from the magnetic field.
-
The cooling of the Earth's core will affect the Earth's magnetic field, which weakens or disappears. The solar wind and cosmic rays are driving straight in, and the earth's creatures will face extinction. Moreover, under the action of the solar wind, the earth will be heated, the water will evaporate, the atmosphere will thicken, and the air pressure will soar, just like Venus now.

Hello, terrible things will happen to the cooling of the earth's core, the cooling of the earth's core will cause the global climate to become cold, and animals, animals and humans will not survive. In addition, cooling will also cause chaos in the earth's magnetic field, which will directly be transferred to the cosmic radiation, and it may be directly destroyed by Brother Tanhuai.
-
Then our planet will be destroyed, and the buildings will cease to exist, let alone human breath. There is a possibility that the earth will fall.

This week, researchers published Wang Cong's article in the journal Earth that the Earth's core is cooling faster than previously thought, which will inevitably accelerate the planet's becoming uninhabitable.
In fact, from the day the Earth was born, the Earth's interior began to gradually cool down. This, of course, played a crucial role in the later birth of life and civilization on Earth.
"This view raises the question of how quickly the Earth has cooled throughout Earth's history, which is directly related to the fundamental question of how long the Earth will remain dynamically active," the scientists wrote in **.
How quickly this process can happen is the subject of research at the moment.
A team of scientists studied Bridgemanite, a common conductive mineral that is trapped between the Earth's core and mantle.
They found that it was twice as conductive as previously thought, meaning that the Earth's cooling process may be faster than previously thought.
When the Earth cools, it loses the magnetic field that protects the Earth from harmful cosmic rays. At that time, the Earth will become a barren, uninhabitable planet.
Researchers aren't bold about how long life on Earth can last.
However, in 2013, Andrew Rushby of the University of East Anglia in the United Kingdom concluded that life on Earth would last for another 100 million to 100 million years assuming no nuclear holocaust, asteroid impact or other unforeseen catastrophes.

The core of our planet is a piping hot place. Of course, this may not seem to be the case in the cold, dark early morning, or in the middle of winter, but beneath the Earth's surface, there is a scorching center made almost entirely of metal. The outer core is an iron-nickel alloy that acts as a buffer between the inner core and the mantle, which is a layer of magma and molten rock.
The core is a solid, iron-rich sphere that is about 750 miles (1,207 km) thick. It is also the hottest place on Earth, with temperatures reaching 11,000 degrees Fahrenheit (6,093 degrees Celsius).
With the discussion about the harmful effects of global warming these days, you might think that the Earth's core might cool down a bit. In fact, we need the center of the Earth to stay blazing hot in order to protect the Earth from potentially harmful solar winds and debris.
The Earth's core is as hot as the surface of the Sun. It began 4.5 billion years ago, when the planets were first formed from clouds of gas and particles. Gravity causes iron and other heavy materials to sink toward the earth's core, while lighter materials such as air and water rise to the earth's crust.
The material in the middle is so heavy that the gravitational pull of the outer core is about three times that of the Earth's surface. It still retains some of its former heat, plus the heat generated by the gravitational friction caused by the movement of the more respectful dust matter near the center. The inner core continues to grow at a rate of about one centimeter per thousand years, gaining more heat in the process of expansion.
Decaying radioactive isotopes also add heat when radiated from the Earth's mantle.
If the Earth's core is completely cooled, the Earth will become cold and die. It can also get a little darker: power companies extract radiant heat from the earth's crust and use it to heat water, which is the power of turbine power [**:anuta].
Cooling may also cause us to lose the magnetic mask formed by the heat generated by the Earth's core around the Earth. This barrier protects the earth from cosmic radiation. The shield is made by constantly moving iron, which is caused by the convection process.
Just like the planet itself, the Earth's core is constantly spinning, and some scientists believe it is moving even faster than the rest of the planet. Friction converts kinetic energy into electrical and magnetic energy that forms a magnetic field, which turns harmful charged particles from the Sun towards the North and South Poles [**: Folger, U.S. Geological Survey].
To what extent the loss of magnetic field will change life on Earth is unknown. Some say that the planet could be violently hit by radiation waves, causing the Earth to overheat and become uninhabitable. Others point to an increase in sunlight, which is believed to be carcinogenic.
More observers say we could experience a sweeping solar wind that could be comparable in intensity to that sweeping across all the oceans, lakes and rivers on Mars and Venus. To be sure, we'd better not figure out what it really means to lose the magnetic field.
At first, a large amount of gas (mostly hydrogen) is attracted by its own gravity and collapses into a star, and when it collapses, the gas atoms collide more and more frequently (and at higher speeds), making the gas hotter and higher, and the molecular thermal motion intensifies, and the hydrogen atoms collide at extremely high speeds, so that when they collide, they do not bounce off but converge to form helium. Like the hydrogen bomb**, it releases a lot of heat, and the extremely high temperature increases the pressure of the gas to reach the equilibrium point with gravity (that is, it is neither affected by gravity and continues to collapse, nor expands outward due to air pressure), however, with the consumption of fuel, the heat that can be provided is less and less, and gradually it cannot resist gravity, so the star begins to continue to collapse (don't think that the more initial fuel of the star, the longer it will live, because the greater the mass of the star, the greater the gravitational force, the more heat required to fight gravity, the faster it will be consumed, Our sun can live for another 5 billion years, and some big stars can consume the same amount of heat in 100 million years). If the mass of a star is less than the Chandrasekhar limit (such as the Sun, the Chandrasekhar limit is one and a half times the mass of the Sun, below the Chandrasekhar limit it will not collapse into a black hole, and if it is exceeded, it will. >>>More

The gravitational field of a black hole is so strong that any matter that comes near it will be absorbed by it, and even light that is as fast as 300,000 kilometers per second cannot escape when it reaches the edge of its event horizon, so if the black hole is in a place where it is extremely rich in matter, its mass can grow rapidly. Almost all galaxies have a massive black hole at the center, and it is constantly eating away at the black hole's material, so will this black hole eventually eat the entire galaxy? >>>More
