Earth s gravitational pull 50, where does Earth s gravitational pull come from?

Comrade, gravity is generated by mass, whereas magnetic field is generated by magnetism or when there is an electric current.

Until gravity and electromagnetism are not unified, it is better not to think about this.

The earth is a product of the great **, the earth has a liquid core of high-temperature lava, a core, a mantle, and a crust.

Why is the center of the earth hot? Some people say:

It is the decay of radioactive elements. For example, elements such as U, Th, and K have some radioactive isotopes, which produce a lot of heat when decaying.

It is also said that in the early days of the earth's formation, the geocentric pressure caused by the gravitational pull of the earth's material made the earth's temperature extremely high, leaving the entire earth in a lava state. As the heat is dissipated, the Earth's outer layers form a crust, but the temperature inside remains high.

There is also the sun's irradiation, the rotation of the earth, gravitation, and so on. The possibility of what they say is not ruled out.

The earth has gravity, and everything that has mass is affected by it.

When we jump upwards, it is very difficult, and horizontal jumps are much easier and farther than upward jumps.

So gravity is perpendicular, and everything is towards the center of the earth.

How does gravity come about? Is there a direct correlation with the internal temperature of the Earth's core?

Suppose that after the universe is large, at the beginning of the formation of the earth, the energy or some matter produced by the high temperature is accumulated. This aggregate is the center of the earth. ** The impact and the fact that there is no resistance to the universe and the influence of gravity make this aggregate rotate horizontally and vertically at high speed.

Suction is created during this process. Gravity. Just like a spin dryer, the center point is suction, which is a rotation in one direction.

When the object is constantly rotating, friction with the particles will produce heat, and the aggregate will continue to absorb the surrounding particles, continue to grow, and the temperature will gradually increase. After reaching a certain amount, the exterior gradually cools to form the core, mantle, crust and now the Earth.

The center of the earth has always been in a liquid state due to high temperature, and the center of the earth rotates at different speeds in the transverse and longitudinal directions at high speeds, driving the rotation and revolution of the earth. Just like a certain decompression artifact, the fast speed of the inner ring drives the slow rotation of the outer ring.

For example, the moon and other explored planets have a slow geocentric rotation, with the earth orbiting for 24 hours and the moon orbiting for 648 hours.

648 hours, 24 hours, 27 days.

The Moon rotates 27 times slower than the Earth, so the Moon's gravitational pull is lower. The Earth's core velocity will only be lower. If you want the inner ring of a liquid to drive the outer ring of a solid, the load required can be multiplied.

In addition to using technology, we cannot escape the gravitational pull of the earth, we are like its children and do not let us leave its arms!

If one day, you also want to fly. Let's find a stick together, and then, put it in, and get it stuck! Then I can fly [covering my face].

The above is a personal opinion, if I say something wrong, I have been afraid of pain since I was a child.
