Why is it easy to go to heaven and difficult to enter the earth?

Because today’s technology cannot penetrate deeper into the ground.

In terms of mass, the core accounts for 16% of the total mass of the earth, the mantle accounts for 83%, and the crust, which is most closely related to us, only accounts for 1%. So the earth we touch is actually like the peel of an apple cut open with a knife, limited to a thin layer. It is said that the most advanced drilling rigs in the world can only drill to a depth of 10,000 meters. As for what it is like under 10,000 meters, scientists can only analyze it based on volcanic eruptions, earthquakes or some faults.

The scientific community is still at the stage of divergent opinions about what kind of material is deep in the earth and what state it is in. It is difficult to simulate it even in the laboratory. But there is one thing that scientists are convinced of - the interior of the earth is an extremely unstable world, and various materials inside the earth are always in constant motion.

The deepest place that scientists have ever drilled is more than 12,000 meters. In that place, the pressure and temperature are very high, but scientists believe that those super microorganisms called "extremophiles" Bacteria are able to survive the incredibly difficult conditions underground. Take the bacteria that live near deep-sea hot springs. They don't need sunlight or oxygen, and can tolerate high temperatures of hundreds of degrees Celsius.

And some underground bacteria are even more amazing. The most impressive is an extremophile called Deinococcus radiodurans, which can survive in different extreme conditions, can be dried, and can Withstand high doses of ultraviolet rays and ionizing radiation 2,000 times lethal to the human body. Therefore, it is not yet possible to draw a conclusion as to whether "people from the center of the earth" exist.
