The central location of the world is 6,000 kilometers underground, or even the outer boundary of the Earth's core, which is the center of the Earth. The location of the center point of the earth is known, but it is difficult to explore it, and the current technology does not support the exploration of the center point of the earth. At the same time, there is a magical thing at the center of the earth, which is the outer core.
It exists in the center of the Earth, but it is about the size of Pluto. On top of that, the core is so hard that it's about to catch up with the sun. The mass of the Earth's core accounts for 31 of the mass of the entire Earth
5%, which is 16 2%。According to the changes in the ** wave, it is found that the earth's core also has the difference between the outer core and the inner core.
The interface between the inner and outer cores is about 5155 km.
EarthThe Mystery of the Center of the Earth
The earth is composed of three parts: the crust, the mantle, and the core, but this understanding should be said to be very superficial. Because according to the current state of science and technology, human drilling is only 35 kilometers deep, and the deepest exploration well (on the Colis Peninsula) is only 12 kilometers. The radius of the earth is 6,300 kilometers, and when we compare these numbers, we will find that the earth we touch is actually like the peel of an apple cut with a knife, limited to a thin layer.
However, human beings are not ignorant of the earth, and intelligent human beings are constantly looking for answers to their questions in the depths of the earth according to the changes in the movement of the earth. The volcanic activity of the earth tells us that the underground hot magma is divided into acidic magma with more silicates and alkaline magma with less silicate according to the magma flowing to the earth's surface.

This part of today's reading is more interesting, the philosopher mentions two different concepts: "the center of the world" and "the center of the world map". The map we use on a daily basis is centered on China, with Europe and America on the left and right; The map used in France is France-centric, and the relative locations of the Americas and Asia are different from what we are used to.
From this can be compared to the way we look at the world cautiously, most of the remarks and behaviors we make are based on ourselves, and the suggestions put forward from such a position are not necessarily applicable to others, just like the old saying "whether the shoes fit or not, only the feet know" Everyone has their own considerations and difficulties, and the focus of their eyes is different.
So what can be done to avoid this? You can try the perspective of the globe, put the world on the globe, and each country is the center of filial piety. When you look away from yourself and put yourself in the other person's shoes, the center of the world is no longer yourself.
