Tunnel is Dug Across the Earth: If one can reach America from India in just a few minutes, then how small will the world become. When we dig a tunnel to reach the other end of the world, we have to cover the diameter of the earth, which is about 12,742 km long. Whereas the maximum depth of the tunnel dug by the Russians in Kola Well is 7 km (23,000 feet)

The idea of digging a tunnel through the earth has always been very interesting for humans. Imagine how small the world would become if one could travel from India to America in just a few minutes. Much faster than air travel, this journey could be possible with the help of gravity. But is it really possible? What would happen if a tunnel is dug through the earth and what would be its effect?

Well, when a tunnel is dug through the earth, it becomes very easy to travel from one country to another. For example, you can reach America from India in just a few minutes. But is it possible? In short, we do not have the engineering capability to do this. However, there was an attempt once, which lasted for about 19 years. Meanwhile, now many researchers have tried to dig tunnels and check how far they can reach inside the earth. So let’s know whether it is possible or not.

Can you dig to reach other side of the world
When we dig a tunnel to reach the other side of the world, we have to cover the diameter of the earth, which is about 12,742 km. While the maximum depth of the tunnel dug by the Russians in Kola Well is 7 km (23,000 feet). This project was started in 1970 and this depth was achieved within five years. Then it was cancelled in 1989, because while digging, the drilling got stuck in a hard rock bed at a depth of about 12 km below the surface of the earth 🌍 why is digging deep so difficult
The temperature at depth is very high (more than 500°C). The rocks are extremely hard and solid. The pressure is so high that machines fail. Due to all these reasons, making a tunnel through the earth is impossible even with today’s technology. This is the reason why the engineering challenges in digging the tunnel will be huge. Even if digging is done from both sides, it will not be possible, because in both attempts, a distance of more than 6000 kilometers will have to be covered. But still people will definitely have this question in their mind that what will happen if digging a tunnel anywhere in the world is successful?

What if we get successful in digging a tunnel around the world 🌎

We have always imagined that by digging a tunnel so far, we can reach the other end of the world. This means that if we measure the distance in terms of diameter, we will reach from the Northern Hemisphere to the Southern Hemisphere.

What will happen if a tunnel passes through the centre of the earth? If we jump into that tunnel, we will move at the rate of 9.8 m/s2 and reach the centre due to the force of gravity. It will take about 21 minutes to reach the centre. During this time the speed of the human will be 28,000 km/h.

According to physics, when a person reaches the center of the earth, his behavior changes and he becomes weightless. While falling in the tunnel, after reaching the center, the inertia moment of the person will go against the Gravitational Force and take him to the other end. It will take him 21 more minutes to reach the other end of the tunnel. When he reaches his place, his speed will decrease from 28,000 km/hr to zero. The opposite point of that tunnel is called antipode.

What is antipode
You don’t need to dig a tunnel to find the antipode. It is the point exactly opposite to the start of the tunnel. Another example is that if you dig a tunnel in China, you will reach the antipode in Argentina in the Southern Hemisphere.

How to calculate the antipode?

It is obvious that the antipode will always exist on the other side of the other hemisphere on Earth. For example, if one considers a location in Memphis at 35° north latitude, its antipode will be somewhere in the Southern Hemisphere at 35° south latitude.

Is it possible to dig a tunnel through the earth

It is impossible to reach the antipodes by digging a tunnel from one place on Earth. To travel that far, one would have to cross a hot lava core. Despite engineering advancements, humans cannot do this in the present era.

However, in the future it may be possible that humans master the technology of traveling through the Earth through tunnels. You will be surprised to know here that traveling through these tunnels will not only consume less energy but also less time. Because the entire work will be done by gravity. This means that you will not have to spend any force to reach the other end of the world. Whereas it will take only 42 minutes to cover the diameter of the Earth.
