Following is a records of the video.
Storyteller: If you wish to get to the opposite end of the world, it’s a walking. About 20,000 kilometers. However what if you didn’t need to take a trip throughout the surface area? What if you could dig directly through to the opposite?
If you’re attempting to dig to China from the United States, there’s something you ought to understand initially. The opposite point on earth isn’t in China. It’s someplace in the middle of the Indian Ocean. So, to get to China, you ought to begin digging in either Argentina or Chile.
Your very first difficulty would be digging through the Earth’s crust. It’s the thinnest of Earth’s 3 primary layers, yet human beings have actually never ever drilled all the method through it. As you come down, you ‘d quickly reach the depth of the Paris Catacombs, the inmost city station, and the devil worm, the inmost animal we have actually ever found underground.
Then, it would begin to fume. At 4,000 meters down, you ‘d pass the inmost mine on earth, which is cooled with ice to make employees comfy, since, down here, temperature levels are 60 degrees Celsius. By 8,800 meters, you’ll be as deep as Mt. Everest is high, however it’s still not the inmost point human beings have actually ever dug. That point is at the bottom of the Kola Superdeep Borehole, at 12,260 meters listed below the surface area. Down here, there’s 4,000 times more pressure than at sea level, and temperature levels push 180 degrees Celsius, so you ‘d require a great deal of insulation to continue and avoid melting.
At around 40,000 meters, you ‘d reach Earth’s 2nd and biggest layer, the mantle, that makes up a tremendous 84% of the world’s volume. Near the border, temperature levels reach around 1,000 degrees Celsius, hot enough to melt numerous metals, like silver, however not a steel drill. And advantage since you’ll require it to drill through the very first part of the mantle, which is made from strong rock, till you reach 100,000 meters, that is, when you may require to change to a prop.
Here, the pressure and temperature level are so high that, in some locations, rock handles a caramel-like consistency. In reality, it’s this rock that eventually emerges from volcanoes on the surface area. At 150,000 meters, keep your eyes peeled for diamonds. They form when heat and pressure restructure the carbon atoms in this area. When you reach 410,000 meters, the rock is strong once again, so it’s back to the drill. You see, while it’s still plenty hot at this depth to melt rock, the pressure is so severe that the particles inside actually can’t move into a liquid state.
Then, by 3 million meters down, you ‘d reach Earth’s 3rd layer, the external core. Unlike Earth’s crust and mantle, the core is made from iron and nickel. Temperature levels here are the very same as the surface area of the sun, hot enough to melt all that metal, so, yep, back to the prop. And it would need to be constructed out of some sort of supermaterial, since no recognized component has a melting point above 6,000 degrees Celsius. Making matters worse, the external core likewise has low gravity, because, when you’re that deep, much of the world’s mass is now above you, which produces a gravitational force that retreats from the center. So to continue, you ‘d require an extremely heat- and pressure-proof submarine that moves like rockets in area by shooting fuel out the back end.
You ‘d quickly get to the inner core, around 5 million meters listed below the surface area. The inner core is one huge sphere of strong iron, so it would absolutely be challenging to make it through. However if you did discover a method, you ‘d quickly strike the middle, about 6.4 million meters down, likewise called the center of the Earth. Now, there’s almost the very same quantity of mass all around you, pulling you similarly in all instructions, so there’s no gravity here.
And now is when the journey actually gets hard. The 2nd half. Due to the fact that as you dig past the inner core, you ‘d quickly feel the pull of gravity once again. And this time, it ‘d be pulling you from above, where most of Earth’s mass is now. So while you may be digging down, relative to where you began, it’ll seem like you’re going up. And if you didn’t have those helpful rockets moving you, you ‘d fall right back to the core. However 6.4 million meters later on, after powering through impenetrable iron, molten alloy, and strong and mushy rock, you ‘d show up, at long last, on the other side, in China.
That would definitely come as a relief, however it would not even be the very best part. Presuming you left a tunnel through the center of the Earth behind you, you ‘d now have the ability to take a trip back and forth in between China and Argentina in under an hour, just by leaping in. To discover why, take a look at another video we made about leaping through the center of the Earth.
