It will be a lifelong journey if you don't mind going through molten rock and crushing pressure. What will you see along the way?
How long will it take to get from one place to another on the earth?
And how will the train of gravity keep you alive?
The heat is high, and you're under pressure.
Imagine traveling from Argentina to China in less than an hour. All you need is a hole in the ground. But digging this hole will be the most challenging part of the effort.
You can fire a massive laser on the ground in a supervillain style. But today, we will travel through the most significant hole in the history of our planet.
The first thing you need to do is dig a deep hole that humanity has never thought of. We have already drilled a hole in the ground. So you know what to do. First, you will need a giant drill. And this project will take a few years to complete. You will be working in extreme heat and pressure.
But when the hole is closed, you will have your own gravity tunnel, a gateway between one side of the earth and the other. I will explain how it will work in a moment. Next, you will need a comfortable vehicle to cross the ground.
If you just jump into the depths of the earth, you will burn and crumble into pancakes. So get on the gravity train. This train will accelerate using only the force of gravity. And it will protect you from extreme heat and extreme stress.
The journey's first stage will take you through the earth's crust. The crust can be 5 to 70 kilometers (3 to 43 miles) thick, depending on where you start your journey. And surprisingly, it makes up only 1% of the whole earth.
You will find your journey relatively carefree. And 20 meters (67 feet) below the surface, you'll be on a subway or level like Paris Catacombs. But let's go a little further. At 2.5 kilometers (1.4 miles), you will be as deep as fossils have been discovered.
The deepest living animal
And once you reach 3.6 kilometers (2.2 miles), you will be able to see the devil (Halicephalobus Mephisto). It is the deepest living animal ever found. Is it just me, or is it getting hot? Believe it or not, some people are working in this depth. Gold mines in South Africa are so low that heat is a problem. And believe me, you won't enjoy the 60 ° C (140 ° F) temperature there.
Then gravity will take you further down. At 8.8 kilometers (5.5 miles) below the surface of the earth, you must have traveled more than the height of Mount Everest. And 11 kilometers (36,037 feet) underground, you'll be more profound than the Mariana Trench.
The deepest hole on the earth?
At 12.26 kilometers (7.61 miles), you will reach the depths of the Kola Superdeep Borehole. This is the most bottomless hole we have ever dug. And you will really feel a lot of pressure on your body.
At this depth, the air pressure is 4000 times higher than the sea level. As you approach the end of the first part of this epic journey, you will come across a lot of gems. I am talking about rubies, sapphires, and emeralds. They can be valuable gifts if you take them to the other side of the earth.
And 40 kilometers (25 miles) down, part of your journey will be behind you. It's up to you how you look at it.
Most people think that its structure is like lava. But in that depth, relatively speaking, this rock is solid. It will start to melt when you are deep. This will be the longest part of your journey. The mantle makes up 84% of the earth's volume.
The mantle is about 2,900 kilometers (1,801 miles) thick. You won't see anything in it except for one brilliant exception. A great deal of pressure and heat forms a diamond at this depth. They make their way to the surface of the earth through volcanic activity. And this is where we humans find them. But you are lucky to find them at their birthplace.
As you get about 410 kilometers (255 miles) below the surface, things start to get weird. The mantle rock will melt and warm. But the veil would be tightened instead of staying in its molten state. This is due to extreme pressure.
At the bottom of the mantle, just 1,000 kilometers (600 miles) below, you will experience the power of mantle blobs. These are hot rock supercharged plums. And if they do, they will become catastrophic supervolcanoes. Needless to say, you will feel very hot.
You will be about halfway across the earth, which should mean you are approaching the outer center. The outer core is made of iron and nickel at a depth of 3,000 km (1,864 miles). Will it be hot? Your ambient temperature will range from 4,500 C to 5,500 C (8,132 ° C to 9,932 ° F). 5,000 kilometers (2,107 miles) below the surface, you will reach the inner center of the earth.
The mind-boggling temperature of this giant solid iron circle is 5,200 ° C (9,392 ° F). And the pressure is 3.6 million times higher than the sea level. Let's hope your gravity train is ready to take on these extreme temperatures and pressures. I haven't read the booklet, but I'm sure you'll be fine.
Eventually, you'll be able to make it halfway through your underground journey. At the exact center of the earth, the mass will be equal in all directions. And you have to experience zero gravity.
But remember, it was only half the journey. You have to do it all over again. This trip will put a lot of pressure on you. This will make you warm, probably uncomfortable. You've collected all the diamonds, haven't you? How long do you think it will take to move from one side of the earth to the other?
Now it's time for me to tell you more about the Gravity Tunnel. It is a passage through the earth. Or just a hole in the ground, as I say. If made correctly, you can travel from one side of the earth to the other in about 42 minutes using the Gravity Train.
But as I mentioned earlier, traveling through the earth would be easy. If we can do that, it will revolutionize the journey. And you will have a short but incredible journey.
