When you were little, you must have thought one thing, that if you start digging a hole in the ground, can you reach another part of the earth? This question is so common that almost every child has wondered, however, you may not have been able to find the answer until you grew up. So today we will remove this dilemma of yours. What happens if a hole is made through the earth (What happen if we fell in a hole through earth center) and an object is thrown into it?
Under News18 Hindi series Ajab-Gajab Gyaan, we bring for you such unique information which can surprise you. Today we are talking about making a hole in the earth, which goes through. Actually, a question related to this has been asked on the social media platform Quora, which has been answered by many people. However, those are the answers of common people, so we cannot say with certainty how correct they are.
What answers did people give on Quora?
Animesh Kumar Sinha said – “That object (space) will continuously move from one end of the Earth to the other and back to the center of the Earth, which is called simple harmonic motion. It is like the pendulum of a wall clock. In physics, this is called gravity tunnel problem or gravity train problem. A person named TS Ramani said- “It depends on the force applied on the thrown object. At half the distance through the hole across the Earth, i.e. at the center of the Earth, objects become weightless, but not massless. A lot of force will have to be applied to take the object to the center of the Earth. Then a lot of power will have to be applied to move it from the center of the Earth to the other side of the Earth. Then energy will have to be applied to pull it out of the Earth’s gravitational field. “A very powerful rocket would be needed to throw the object across the hole in the center of the Earth.”

What will happen if a hole is made through the earth?
According to Science ABC, a science-based website, first of all, it is impossible to create such a hole which divides the Earth into two parts and comes out from one side and goes to the other side. Some facts related to this have been mentioned on the website.
The deepest pit that humans have ever dug is the Kola borehole in Russia, which was only 12 kilometers deep. Even if someone stood at the bottom of this hole, he would come only 0.3 percent closer to the earth’s surface.
The core of the Earth i.e. the middle part is made of boiling lava and metals which are rotating at very high speed. The temperature here is around 6 thousand degrees Celsius. It is so hot that a human body will instantly turn into ashes. In such a situation, there will be no way to cross the core and reach the other side of the Earth. Now whether it is a human being or any other thing, it will have the same outcome.
Within minutes of the jump, the person will die from claustrophobia or lack of oxygen. The pressure on the earth’s core is so high that if a hole of the size of a human palm is made in the earth, it can cause a huge explosion which can kill the creatures living on the surface.
