【History Talk】Hollow Earth Theory

What exactly exists at the Earth's core? It has always been a question that scientists have long wanted to explore. CNN published a new research report on February 21, 2023, stating that scientists already have evidence to explain that the innermost layer of the earth’s real core is a 644-kilometer-wide metal ball. and nickel are the main components, which means that this iron ball is the real core of the earth. The new discovery will likely overturn and rewrite the existing earth science textbooks.

If it is true, as scientists say, that the Earth's structure is divided into crust, mantle, liquid outer core, and solid inner core from the outside to the inside, the latest discovery this time is that there is a real Earth core in the inner core. Xie Xiangyu, a researcher at the Beijing Planetarium, said that such a small core is used to study the refraction and reflection of seismic waves in the interior of the earth through seismology. It is estimated that the detailed structure of the interior of the earth cannot be reached.

When it comes to the center of the earth, we have to mention the Hollow Earth Theory, which was very popular in history. Even people who don’t understand geology will laugh at you in modern times. But if you go back to more than 330 years ago, let alone ordinary people, even top astronomy Everyone is convinced, and today I will talk about this piece of history.
