what if you just keep digging?


 

     Imagine sitting on a specially built drill ready to Bow through the Earth from one side to the other at first it might seem like a thrilling idea just dive into a tunnel free fall at incredible speeds and shoot out from the other side of the planet like a human bullet but as cool as it sounds this journey is a recipe for disaster let's break down why you see Earth isn't just dirt and rock it's a layered structure each layer more intense than the last so the first first challenge we'll be facing is drilling through the crust the outermost lay about 60 M thick this is where we live and even though it sounds manageable digging deep is no easy task the deepest hole ever drilled here is the cola super deep bore hole in Russia which only reached 7.6 miles and that's barely a scratch on the surface yes go deeper and you'd face skyrocketing pressure 4,000 times more than sea level and temperatures hot enough to melt steel but let's keep going through the crust and enter the mantle a 1,740 m thick layer of molten rock and shifting tectonic plates temperatures here so to over 2,570 de F and a regular drill would melt instantly so to survive this part of the journey you'd need a drill made of incredibly tough materials like titanium next comes the outer core a swirling sea of molten iron and nickel about 1,800 00 M below the surface temperatures here range between 7,200 F and 9,000 fah basically a giant ocean of lava and because it's a liquid metal digging through it would be like trying to carve a paath through molten soup still for the sake of imagination let's say you keep going if you somehow make it past the outer core you'll reach the inner core here the pressure is over 350 million times what we experience on the surface even though temperatures Remain scotching the immense pressure keeps the iron and nickel solid at this point your drill would be under unimaginable stress likely destroyed long before reaching the other side but let's suppose you managed to leave the inner core as you pass the earth center gravity starts pulling you back toward the side you originally came from rather than continuing toward the other side the further you move away from the center the stronger gravity becomes making it feel like you're being dragged back again the outter cor mold and turbulent is just as tough to navigate the second time plus now gravity is actively resisting your movement after fighting your way back through the outer Co You' reenter the mantle where the heat and pressure are still extreme yet as you climb closer to the surface gravity eases up and drilling becomes slightly less grueling finally you reach the crust again which compared to the inner earth seems like a breeze and then you've done it you've drilled through the entire planet traveling thousands of miles through rock molten metal and intense heat but what's the result well unless you're careful you might pop out in the middle of the ocean or in in someone's backyard since most of the earth's surface is covered by water you'd probably end up swimming with the fish what an anticlimactic end to a wild Journey triv your time did you know the boundary between the mantle and the crust is called the moo yes it's shot for mooro bich.



Thank you...

It's time for the world to end | 5 planets destroy |

  Have you ever wondered how will our world end?  If famous physicist stephen Hawking is to be believed he made some weird predictions about the future. He said that he was worried that someday ai artificial intelligence will completely replace humans. a form of life will evolve that would outperform humans. this perhaps would be the worst thing for humanity he also warned about climate change soon global warming would reach a point of no reversal but if artificial intelligence and climate change cannot end the world according to stephen Hawking in the next 1000 years we will definitely witness some nuclear confrontation and an environmental catastrophe. He said that if human want to avoid extinction over the next 100 years we would need to colonise some other planets....

Egyptian pyramids terrifying truth shocked scientists | pyramind mystery solved |

The  great Pyramid of Giza :     white a hight of 147 meters this remained the tallest structure in the world for over 4000 years. heavy stones were used to build the pyramid and its is said to weigh 6 million tonnes. the question that people dumbstruck how was it built?
