What happens if you fly through the Earth?

The Funniest part of theoretical physics is that you can ask a stupid question and get your answer (sometimes too stupid). For example, what if you drilled a hole through the center of the Earth and leap through it? "Who could do such a stupid thing to do?" - You ask. Apparently no one. Such an act will kill you very sophisticated and split the millions of times. Let's assume that some brave soul ventured into it for the sake of science? What can happen, theoretically?


First, let's state the obvious: you can not drill a hole through the center of the Earth. To say that we do not have enough technical capacity to carry out this significant effect will be a very great exaggeration. But, of course, we can drill a hole in the ground at all. How deep we went?

To date, the deepest hole in the world is Kola ultradeep well. Its drilling began in 1970 and ended 20 years later when drillers reached a depth of 12,262 meters. It is about 12 kilometers. But it is not even a hair compared to the diameter of the Earth. Why are we stopping? As you approach the center of the Earth heats up everything. This is because the Earth's core consists of liquid metal and heated up to 5400 degrees Celsius. And even at a depth of 12 kilometers drillers faced with a temperature of 170 degrees Celsius.

I think you know that at this temperature, you will not live long. But if you manage somehow to dive even deeper, at a depth of 48 kilometers you will find the magma. At this point, you'll be incinerated.

And even if we assume that you have managed to overcome this embarrassing inconvenience, if you have developed some sort of pipe that allows you to safely pass through the burning magma, you would kill the very air. More specifically, the air pressure. Just as you feel the pressure, plunging deep into the water, you feel the pressure when at you a lot of air (hence the thick atmosphere of Venus you flatten into a pancake). On our own planet you need to dive to a depth of 50 kilometers, before the pressure in the pipe will be as high as on the ocean floor.

Therefore, if your goal is not to self-destruction, we should not remain at such depths.

But even if you manage to make a pipe that will allow you to penetrate the magma to resolve issues with the air and the suit lot easier for you, there are problems. For example, the rotation of the planet. Halfway to the Center ofCenter of the Earth the Earth, you will move in the direction of about 2,400 kilometers per hour faster than the walls of your chimney. It's not good for your health. You can hit the wall of the tube, and die well, it turns out.

Well, if this question, we have also decided if able to jump through the Earth, your momentum will allow you to drive on the other side of the nucleus. How long will it last?

This is the answer to all the questions, as we know. 42 minutes.

But the fun does not end there. Due to the powerful gravity of the Earth and your powerful impulse as soon as you find yourself on the other side, you will once again fall to the ground. And you come all the way from the beginning. You will oscillate back and forth in a sinusoidal manner as is currently the yo-yo.
